1. LEAD (Plumbum / Pb)

Identification

Soft, bluish-grey, heavy metal
Compounds used as poisons: Lead acetate (sugar of lead), lead carbonate (white lead), lead monoxide (litharge), red lead (Pb3O4), lead sulphide
Hydrochloric acid produces a white precipitate soluble in boiling water, crystallizing on cooling (diagnostic test)

Type of Poison

Inorganic metallic poison; heavy metal; cumulative poison

Fatal Dose

Acute: ~450-500 mg of lead acetate; chronic - no fixed safe threshold
Blood lead >70 µg/100 mL is considered severely toxic

Fatal Period

Acute poisoning: several days to weeks
Chronic poisoning: months to years (cumulative)

Judicial Uses (2)

Lead missiles (bullets) embedded in tissues may cause delayed lead poisoning - important in forensic investigation of gunshot injuries
Detection of lead in hair, bone, and tissues at autopsy is used to confirm lead poisoning as cause of death in criminal/medico-legal investigations

Non-Judicial Uses (2)

Battery manufacturing, plumbing, paint (white lead, red lead) - occupational/industrial use
Diachylon paste (lead oleate) historically used as an abortifacient

Clinical Features

Acute: Metallic taste, burning abdominal pain, vomiting, constipation
Chronic (Plumbism/Saturnism):
- Facial pallor (especially around mouth - due to vasospasm)
- Anaemia with punctate basophilia (stippled red cells)
- Burton's/Lead line: bluish-black line on gums at junction with teeth (lead sulphide deposits near carious teeth)
- Lead colic: severe intestinal, ureteric, uterine colic, worse at night
- Constipation (classic)
- Lead palsy: wrist drop (radial nerve - extensor muscles of wrist), foot drop; tremors, hyperesthesia
- Lead encephalopathy: headache, irritability, insomnia, convulsions, delirium, coma (more in children)
- Renovascular: Fanconi syndrome, interstitial nephritis, hypertension
- Reproductive: oligospermia, infertility, miscarriage
- Children: low IQ, cognitive impairment, premature birth, delayed growth

Mechanism of Action

Inhibits delta-aminolevulinic acid dehydratase (ALAD) - disrupts haem/porphyrin synthesis
Inhibits 5-pyrimidine nucleotidase - impairs RNA degradation in RBCs - basophilic stippling
Substitutes for calcium at synapses and in bone
Inhibits Na-K ATPase and other enzymes
Causes peripheral axonal neuropathy (demyelination + axon degeneration)

2. ARSENIC

Identification

Arsenic trioxide (white arsenic / As2O3): white, odourless powder with sweetish taste; most commonly used
Other compounds: sodium arsenate, copper arsenite (Paris green), lead arsenate
Marsh's test, Reinsch's test, Gutzeit test for detection
Hair and nails accumulate arsenic (keratin affinity)

Type of Poison

Inorganic metallic poison; protoplasmic and capillary poison; cumulative

Fatal Dose

Arsenic trioxide: 180 mg (but doses as low as 30 mg have been fatal; individual tolerance varies widely)

Fatal Period

12-48 hours after ingestion; may be fatal within 2-3 hours with large doses

Judicial Uses (2)

Hair, nail, and urine analysis (ion emission spectroscopy) for diagnosis and medico-legal proof of chronic arsenic poisoning (Mees' lines in nails are pathognomonic)
Marsh's test on stomach contents / exhumed tissues to establish homicidal/suicidal arsenic poisoning in court

Non-Judicial Uses (2)

Pesticides/insecticides (Paris green - copper arsenite), wood preservatives
Historically used in Fowler's solution (1% arsenious trioxide) as a tonic/medicine; used by homicides due to tastelessness and resemblance to flour

Clinical Features

Acute (within 30 min):
- Metallic taste, garlicky odour (characteristic), dry mouth, dysphagia
- Severe nausea, projectile vomiting (dark brown/yellow, with blood and mucus)
- Profuse diarrhoea - rice-water stools (resembles cholera), bloody in some
- Intense thirst, burning pain in throat and stomach
- Increased salivation, periorbital oedema
- Cramps in calf muscles, restlessness
- Cyanosis, cold clammy skin, hypoxia, convulsions, coma
- Acute tubular necrosis, haematuria, oliguria, proteinuria
- ECG: prolonged QT interval, T-wave inversion
- Death from irreversible circulatory insufficiency
Subacute/Chronic (2-4 weeks after non-lethal dose):
- Hair loss (alopecia)
- Mees' lines: white transverse lines on nails (appear up to a year after poisoning)
- Sensorimotor peripheral neuropathy
- Skin: raindrop pigmentation (melanosis), hyperkeratosis of palms and soles, Bowen's disease
- Hepatitis, cirrhosis, ascites (Fowler's solution)
- Renal failure

Mechanism of Action

Combines reversibly with sulfhydryl (-SH) groups in tissue proteins
Interferes with enzyme systems essential for cellular metabolism (pyruvate oxidation, Krebs cycle)
Capillary poison - dilates capillaries - plasma transudation, hypovolemic shock
Fatty degeneration of liver
Hyperaemia and haemorrhages in intestinal mucosa (vesicle formation, sloughing)
Renal tubular necrosis
Peripheral nerve: disintegration of axis cylinder (axonal neuropathy), fragmentation and resorption of myelin

3. SEEDS OF ABRUS PRECATORIUS (Jequirity / Rosary Pea / Gunchi / Ratti)

Identification

Seeds: oval, egg-shaped, 8 mm long × 6 mm broad; bright scarlet red with a large black spot at one end (hilum); weigh ~105-120 mg
Tasteless and odourless
Also known as: Indian liquorice, Crab's eye, Gulganji
Active principle: Abrin (a toxalbumin/phytotoxin)
Seeds may occasionally be all black, white, yellow, or blue

Type of Poison

Vegetable/organic irritant poison; toxalbumin (phytotoxin); acts like bacterial toxin

Fatal Dose

1-2 seeds by mouth (decorticated/powdered)
90-120 mg of abrin by injection

Fatal Period

3-5 days

Judicial Uses (2)

Malingerers use powdered seeds to produce artificial conjunctivitis - detection is important in medico-legal cases
Suis (poisoned needles made from abrus powder + opium + dhatura paste) used to kill cattle; identification of sui at injury site is key forensic evidence in cattle-poisoning cases

Non-Judicial Uses (2)

Used as arrow poison by tribal communities
Used as an ornamental/decorative bead in jewellery (rosary beads) - inadvertent puncture risk

Clinical Features

When seeds are swallowed whole (raw or cooked): usually not poisonous (intact testa prevents absorption)
When injected / applied to wound (via sui):
- Local: painful swelling, ecchymosis, oedema, necrosis, haemorrhagic fluid from puncture
- Systemic (resembles viper bite): vertigo, cardiac arrhythmia, convulsions, coma, death
- Animal: apathy, drowsiness, refusal of food, unable to move after 3-4 days, coma and death
When ingested as extract/powder:
- Nausea, vomiting, colicky abdominal pain, diarrhoea, haemorrhage, collapse

Mechanism of Action

Abrin inhibits protein synthesis by inactivating the 60S ribosomal subunit (same mechanism as ricin - depurination of 28S rRNA)
Causes agglutination and lysis of red blood cells (haemagglutination)
Acts like viperine snake venom (haemorrhagic, cytotoxic)
Antigenic properties - can raise antibodies (anti-abrin)

4. FRUITS OF SEMECARPUS ANACARDIUM (Marking Nut / Bhilawan / Bhilwa)

Identification

Fruit: black, heart-shaped (cone-shaped) with rough projection at base; thick cellular pericarp
Juice: brownish, oily, acrid; turns black on exposure to air (used by washermen as marking ink)
Active principles: Semecarpol (0.1%) and Bhilawanol (15-17%)
Also called Marking nut tree

Type of Poison

Vegetable/organic irritant poison; vesicant and corrosive

Fatal Dose

5-10 gm

Fatal Period

12-24 hours

Judicial Uses (2)

Juice applied to skin produces blisters resembling bruises (artificial bruise) - important in medico-legal cases involving false charges of assault; must be differentiated from true bruise
Juice used to introduce into vagina as punishment for infidelity - constitutes criminal assault; detection is medico-legal evidence

Non-Judicial Uses (2)

Used by washermen (dhobis) as marking ink on clothes
Used in Ayurvedic/traditional medicine for paralysis and pain relief (Vaidya's administer juice)

Clinical Features

External application:
- Irritation, painful blisters containing acrid serum
- Eczematous eruption spreading to adjacent skin, itching
- Lesion resembles bruise, may ulcerate and slough
Internal ingestion (large doses):
- Blisters in mouth and throat
- Severe gastroenteritis
- Dyspnoea, tachycardia, hypotension, cyanosis
- Absence of reflexes, delirium, coma, death

Mechanism of Action

Bhilawanol acts as a direct contact irritant and vesicant on skin and mucous membranes (chemical burn mechanism, similar to urushiol of poison ivy - same Anacardiaceae family)
Internally: direct irritation of GI mucosa causing haemorrhagic gastroenteritis
Systemic absorption causes autonomic and cardiovascular toxicity

5. CROTON SEEDS (Croton tiglium / Jamalgota / Nepala)

Identification

Seeds: oval, blackish-brown colour with white oily kernel; have longitudinal lines on them
Resemble castor seeds in size/shape (small) but differ in appearance
Oil: brownish, viscid, unpleasant smell, bitter taste
Active principle: Crotin (toxalbumin - irritant and vesicant); also crotonoside (glycoside, less poisonous)
Oil contains powerful vesicating resin (crotonoleic acid, methyl crotonic acid)

Type of Poison

Vegetable/organic irritant poison; toxalbumin

Fatal Dose

Seeds: 4-5 seeds
Oil: 1-2 mL (20 drops of oil)

Fatal Period

6 hours to 3 days (may be as early as 4-6 hours or delayed up to 6 days)

Judicial Uses (2)

Used with homicidal intent - mixed in food; identification of seeds/oil in stomach contents is forensic evidence
Used as abortifacient - taken internally or applied locally; medico-legal significance in criminal abortion cases

Non-Judicial Uses (2)

Used in traditional/folk medicine as a purgative (in small doses)
Used as arrow poison by wild tribal communities

Clinical Features

Hot burning pain from mouth to stomach
Salivation, nausea, copious vomiting
Powerful purging/diarrhoea with burning pain at anus
Vertigo, prostration
External skin application: burning, redness, vesication (blistering)
Collapse, coma preceding death

Mechanism of Action

Crotin (toxalbumin): inhibits ribosomal protein synthesis (similar to ricin/abrin) - cell death
Acts as a direct local irritant and vesicant on skin and GI mucosa
Causes severe inflammatory reaction with oedema, erosion, haemorrhage in GI tract
Oil component (phorbol esters related to croton oil): activate protein kinase C - acts as tumour promoter; causes intense local inflammation

6. SEEDS OF RICINUS COMMUNIS (Castor Seeds / Ricin)

Identification

Seeds: oval, glossy brown, mottled (speckled); two sizes (big and small)
Small seeds resemble croton seeds (~1.25 cm long × 0.85 cm broad)
Active principle: Ricin (supertoxic toxalbumin/phytotoxin)
Castor seeds are poisonous when eaten raw; harmless when swallowed whole (intact testa) or after cooking
Extracted castor oil does NOT contain ricin (non-poisonous)
Residual press cake (after oil extraction) is highly poisonous (contains ricin)

Type of Poison

Vegetable/organic irritant poison; toxalbumin (phytotoxin); supertoxic

Fatal Dose

6 mg of ricin (equivalent to ~10 seeds)
By injection: as little as 1 µg/kg body weight (bioweapon dose)

Fatal Period

Several days (multi-organ failure is delayed)

Judicial Uses (2)

George Markov assassination (London) - ricin-filled pellet fired from umbrella tip - represents political assassination weapon; detection in autopsy tissues is forensic evidence
Used by terrorists - poisoning of water/food or ricin-laced projectiles; used as potential bioweapon; its identification is a forensic/national security matter

Non-Judicial Uses (2)

Castor oil used commercially as a lubricant, in cosmetics, and in Ayurvedic medicine (purgative)
Powder of seeds used to produce local irritation of skin/mucous membranes (by criminals to cause harm)

Clinical Features

Ingestion of raw seeds:
- Burning in throat, salivation, nausea
- Copious and painful vomiting
- Colicky abdominal pain
- Bloody purging (haemorrhagic diarrhoea)
- Dehydration, cramps
- Coma and convulsions preceding death
Dust inhalation (occupational): Dermatitis, conjunctivitis, rhinitis, asthma, allergy
Injection (bioweapon): Multi-organ failure, haemorrhage, death

Mechanism of Action

Ricin is a Type II ribosome-inactivating protein (RIP)
A-chain (ricin toxin A chain): N-glycosidase activity - cleaves a specific adenine residue from the 28S rRNA of the 60S ribosomal subunit (depurination) - permanently inactivates ribosomes
B-chain: lectin - binds to galactose residues on cell surface glycoproteins/glycolipids - facilitates endocytosis of ricin into cells
Result: complete inhibition of protein synthesis - cell death
No specific antidote exists

7. CAPSICUM SEEDS (Chilli / Lalmirch)

Identification

Seeds: ~0.30 cm long and wide; pale yellow, small, thin, smooth and round; embryo curved inward (on section)
Pungent smell and taste
Active principles: Capsaicin and Capsicin (acrid, volatile, non-alkaloidal, non-fatal substances)
Differ from Dhatura seeds: chilli seeds are smaller, paler, smooth vs. dhatura seeds which are larger, brown/black, kidney-shaped, pitted, and reticulated

Type of Poison

Vegetable/organic irritant poison; non-fatal irritant (NOT a lethal poison in ordinary doses)

Fatal Dose

No established fatal dose - considered non-fatal in ordinary quantities

Fatal Period

Not applicable (not typically fatal)

Judicial Uses (2)

Powder used as a means of torture to extort money or confession - introduced into nostrils, eyes, urethra, vagina, or rectum; constitutes assault and torture in law
Chilli bomb (pepper spray) used by police for crowd/mob control - regulated use by law enforcement

Non-Judicial Uses (2)

Universal condiment (red pepper/lalmirch) in food
Used in superstitious practices to scare away evil spirits; burnt to irritate aggressors

Clinical Features

Skin: Irritation, vesication (blistering)
Eyes: Burning, lachrymation (tearing), redness, intense pain
Ingestion: Burning sensation from mouth to oesophagus and stomach; irritant gastroenteritis
Inhalation (fumes): Irritation of eyes and upper respiratory passages

Mechanism of Action

Capsaicin selectively binds to TRPV1 (Transient Receptor Potential Vanilloid 1) receptors on sensory neurons (C and Aδ fibres)
TRPV1 activation causes massive influx of Ca²+ and Na+ - intense burning pain sensation
Depletes substance P from sensory nerve terminals (initially causes pain, then desensitization/analgesia with repeated use)
Direct membrane irritant on mucous membranes at high concentrations

8. DHATURA SEEDS (Datura stramonium / Thorn Apple / Jimsonweed)

Identification

Seeds: brownish to black, kidney-shaped, finely pitted and reticulated; embryo curved outward (on section); bitter taste; odourless; larger and thicker than chilli seeds
Fruit: greenish-grey, apple-shaped with thorny projections ("Thorn Apple")
All parts of plant are poisonous; seeds contain maximum concentration of active principles
Active principles: (1) Hyoscine (Scopolamine), (2) Hyoscyamine, (3) Atropine (anticholinergic alkaloids)

Type of Poison

Vegetable/organic deliriant/cerebral poison; anticholinergic alkaloid

Fatal Dose

50-100 crushed seeds (if ingested)

Fatal Period

1-2 days if untreated

Judicial Uses (2)

Widely used as a stupefying agent for criminal purposes (robbery, rape, kidnapping) - crushed seeds mixed with sweet food or pan-beedi given deceitfully; person commits acts they don't recall - important in law
Used to dope cigarettes or cannabis - forensic detection of hyoscine/hyoscyamine in urine/blood/stomach contents is medico-legal evidence

Non-Judicial Uses (2)

Used by Himalayan Sadhus/ascetics as a psychoactive/religious substance for ages
Hyoscine (scopolamine) is used medically as anti-emetic, for motion sickness, and as pre-anaesthetic medication

Clinical Features (Classic Anticholinergic Toxidrome - "D's")

Hot as a hare - dry, hot skin (anhidrosis + fever)
Blind as a bat - mydriasis (dilated pupils), blurred vision, diplopia; conjunctiva red
Red as a beet - flushed face (cutaneous vasodilation)
Dry as a bone - dryness of mouth, xerostomia, dysphagia; dry skin
Mad as a hatter - delirium, hallucinations, agitation, restlessness, picking at imaginary objects, tries to run/jump, homicidal tendencies
Additional: nausea and vomiting, drunken gait, tachycardia, urinary retention, painful urination
Stupefaction/amnesia - person does not remember events
Convulsions followed by coma and death from respiratory arrest if untreated

Mechanism of Action

Hyoscyamine/Atropine/Hyoscine are competitive muscarinic acetylcholine receptor (mAChR) antagonists
Block all muscarinic effects of acetylcholine: smooth muscle relaxation (GI, urinary), decreased secretions (saliva, sweat, bronchial), tachycardia, mydriasis
Hyoscine additionally has CNS activity: causes delirium, hallucinations, amnesia (crosses blood-brain barrier more readily than atropine)
Antidote: Physostigmine (cholinesterase inhibitor) - 1-2 mg IV slowly, every 5 minutes until signs disappear

9. GANJA (Cannabis / Cannabis indica / Indian Hemp)

Identification

Ganja: resinous mass made from flowering tops of female Cannabis plant, specially grown for maximal resinous exudate; contains ~1-2% (some sources 25%) THC; rusty green colour with characteristic odour; smoked in pipe (chillum) or beedi
Active principle: Tetrahydrocannabinol (THC) (delta-9-THC) - fat soluble
Other preparations: Bhang (dried leaves, 15% THC, least potent), Majun (sweetmeat made with bhang), Charas/Hashish (resinous exudate from leaves/stems, 25-40% THC, most potent)
Cystolith test: microscopic identification; crystals appear like elephant tusk/bear claw; add 10% chloral hydrate, then 20% HCl - CO2 bubbles (effervescence)

Type of Poison

Vegetable/organic cerebral deliriant; hallucinogen; narcotic/psychoactive

Fatal Dose

No scientifically authenticated fatal dose
Some authors mention: IV cannabis ~1-2 g; oral ~700 g as potentially fatal
Lethal dose of ganja: ~8 g/kg body weight (Parikh); charas ~2 g/kg; bhang ~10 g/kg

Fatal Period

~12 hours in acute poisoning

Judicial Uses (2)

Used as a stupefying poison (majun/charas) prior to robbery, kidnapping, and rape - mixed in food/beverages; constitutes criminal use under NDPS Act (India)
THC detected in urine (50-100 ng%) up to 7-8 weeks after use - important in forensic drug testing; positive urine THC is admissible legal evidence; also used to detect doped cigarettes

Non-Judicial Uses (2)

Sadhus and temple priests use it to achieve religious fervour/spiritual states
Medically: THC (dronabinol) approved for chemotherapy-induced nausea, appetite stimulation in AIDS wasting syndrome

Clinical Features

Acute (triphasic pattern):
- Phase 1: Euphoria, relaxation, garrulity, hilarity; colours appear brighter, sounds clearer
- Phase 2: Philosophical thinking, introspection, hallucinations, sedation, increased appetite, conjunctival congestion (characteristic red eyes)
- Phase 3: Tachycardia, palpitation, hypotension, rhinitis, cough, bronchitis; convulsions and cardiac arrest (overdose)
Chronic:
- Cannabis psychosis (manic, schizophreniform, confessional psychosis)
- Amotivational syndrome: apathy, poor concentration, social withdrawal
- Cyclical hyperemesis syndrome
- Suicidal/homicidal tendencies, accidents
- Chronic lung disease, cancers of mouth and larynx, aspergillosis, clubbing of digits
- Hashish insanity: delusions of grandeur or persecution
- "Running amok" - frenzied desire to commit murders

Mechanism of Action

THC acts on CB1 receptors (endocannabinoid system) in the CNS (hippocampus, cortex, cerebellum, basal ganglia) and CB2 receptors (peripheral tissues)
Mimics/modulates endogenous neurotransmitters: GABA, dopamine, acetylcholine, histamine, serotonin, noradrenaline, and prostaglandins
Small doses: CNS excitation; large doses: CNS depression
Being fat-soluble, THC is stored in fat cells - acts as a time-release capsule; effects of single dose last >7 days
Smoking produces immediate effects; oral consumption produces slow, unpredictable effects
Inhibits adenylate cyclase via Gi-protein coupling

For each of the 9 poisons (Lead, Arsenic, Abrus, Semecarpus, Croton, Ricin, Capsicum, Dhatura, Ganja):

Colour-coded card with its own unique theme colour (steel blue, poison green, crimson, amber, orange, purple, red, teal, earthy green)
Active principle named prominently
Fatal dose + fatal period with coloured badges
Key molecular/receptor target highlighted
Mechanism of action (step-by-step)
Clinical features sorted by system/severity (danger/warning/info tags)
Antidote + judicial + non-judicial uses in the footer

Plus a 10-column rapid comparison table at the bottom covering all 9 poisons side-by-side for quick revision.

Design highlights:

Dark forensic theme (professional and print-ready)
Danger badges (red = fatal, orange = warning, green = safe/non-fatal)
"TRPV1" target for capsicum, "mAChR antagonist" for dhatura, "Type II RIP" for ricin/abrin - all mechanistically precise
Classic anticholinergic toxidrome for dhatura displayed as the 5 mnemonics (Hot/Blind/Red/Dry/Mad)

Main Master Table (9 rows × 8 columns) — for each poison:

Column	Content
⚖ Judicial Use 1 & 2	Specific legal/court uses with tags
🔬 Non-Judicial Use 1 & 2	Industrial, folk, ritual, medical uses
📋 Medico-Legal Significance 1 & 2	Criminal types, litigation, reporting duties
🔍 Forensic Detection	Specific tests to identify each poison
★ Key Note	Landmark case or special legal consideration

Three Thematic Summary Panels:

Judicial use patterns across all 9 (homicide types, torture, abortion, bioterrorism)
Non-judicial use patterns (industrial, folk, ritual, pharmaceutical)
Medico-legal significance patterns (DFSA, exhumation, criminal insanity, mandatory reporting)

Quick Mode-of-Criminal-Use Table: shows at a glance whether each poison is used for homicide / suicide / accident / stupefaction / abortion / malingering / special crimes — with colour-coded severity badges.

Highlighted special cases: George Markov assassination (Ricin), Bhola Manucca chocolate case (Ganja), "Running amok" (Ganja), Dhatura as India's most common DFSA agent, Arsenic as the classic "inheritance powder."

This is the same question you asked earlier today — I already provided a comprehensive answer. Here's the complete summary again in clean point format:

1. LEAD (Plumbum / Pb)

Identification

Soft, bluish-grey heavy metal
Compounds: Lead acetate (sugar of lead), lead carbonate (white lead), lead monoxide (litharge), red lead (Pb₃O₄)
HCl test: white precipitate (PbCl₂) - soluble on boiling, crystallises on cooling

Type of Poison

Inorganic metallic poison; heavy metal; cumulative poison

Fatal Dose

Acute: ~450-500 mg of lead acetate
Chronic: blood lead >70 µg/100 mL is critically toxic

Fatal Period

Acute: days to weeks; Chronic: months to years (cumulative)

Judicial Uses

Retained bullet (lead missile) in tissues → delayed lead poisoning after 12-48 days; forensic proof in gunshot injury investigations
Lead detected in hair, bone, and teeth at autopsy → confirms chronic lead poisoning as cause of death in medico-legal cases

Non-Judicial Uses

Battery manufacturing, plumbing, paint (white/red lead), smelting, pottery glazing
Diachylon paste (lead oleate) used as abortifacient; red lead used as cattle poison mixed with arsenic

Clinical Features

Facial pallor (earliest sign - vasospasm around mouth)
Burton's lead line: stippled bluish-black line on gums at junction with carious teeth (lead sulphide)
Anaemia with basophilic/punctate stippling of RBCs
Lead colic: severe intestinal, ureteric, uterine colic (worse at night); constipation
Lead palsy: wrist drop (radial nerve - extensor muscles); foot drop; tremors
Lead encephalopathy: headache, irritability, insomnia, convulsions, delirium, coma
Renal damage: Fanconi syndrome, interstitial nephritis, hypertension
Children: low IQ, cognitive impairment, premature birth

Mechanism of Action

Inhibits δ-aminolevulinic acid dehydratase (ALAD) → disrupts haem/porphyrin synthesis
Inhibits 5-pyrimidine nucleotidase → impairs RBC RNA degradation → basophilic stippling
Substitutes for Ca²⁺ at synapses and in bone
Inhibits Na⁺K⁺-ATPase and vital enzyme systems
Causes peripheral axonal neuropathy (demyelination + axon degeneration)

2. ARSENIC (As₂O₃ - White Arsenic)

Identification

White arsenic (As₂O₃): white, odourless powder, slightly sweetish taste
Paris green (copper arsenite), sodium arsenate, lead arsenate
Garlicky odour of breath/vomit (characteristic)
Marsh's test, Reinsch's test, Gutzeit test
Keratin affinity: concentrates in hair and nails

Type of Poison

Inorganic metallic poison; protoplasmic and capillary poison; cumulative

Fatal Dose

Arsenic trioxide: 180 mg (as low as 30 mg can be fatal)

Fatal Period

12-48 hours; can be fatal within 2-3 hours with large doses

Judicial Uses

Marsh's/Reinsch's test on stomach contents and exhumed tissues - legally admissible evidence of homicidal poisoning; arsenic persists in tissues for years after burial
Hair and nail analysis (Mees' lines - 1 line = ~1 month exposure) to prove chronic poisoning, establish timeline and duration in court

Non-Judicial Uses

Pesticides/insecticides (Paris green), wood preservatives, semiconductor manufacturing
Fowler's solution (1% As₂O₃) - historical tonic/medicine; herbicides containing arsenic

Clinical Features

Acute (within 30 min): metallic taste, garlicky odour, dry mouth
Severe nausea; projectile vomiting (dark brown, bloody)
Profuse diarrhoea with rice-water stools (resembles cholera)
Intense thirst, burning pain in throat and stomach
Calf muscle cramps, restlessness
Cyanosis, cold clammy skin, hypovolemic shock
Acute tubular necrosis, haematuria, oliguria
ECG: prolonged QT interval, T-wave inversion; death from circulatory failure
Chronic/subacute: Mees' lines on nails; raindrop pigmentation (melanosis); alopecia; hyperkeratosis of palms/soles; peripheral neuropathy; hepatitis/cirrhosis

Mechanism of Action

Binds reversibly to sulfhydryl (-SH) groups in tissue proteins → enzyme inhibition
Inhibits pyruvate oxidation and Krebs cycle → cellular energy failure
Capillary poison: dilates capillaries → plasma transudation → hypovolemic shock
Intestinal mucosal vesicle formation and sloughing → bloody diarrhoea
Fatty degeneration of liver; renal tubular necrosis
Axonal neuropathy: axis cylinder disintegration, myelin fragmentation

3. SEEDS OF ABRUS PRECATORIUS (Gunchi / Rosary Pea / Ratti)

Identification

Oval, egg-shaped seeds; 8 mm × 6 mm; weight ~105-120 mg
Bright scarlet red with large black spot at one end (hilum)
Tasteless and odourless
Also: Indian liquorice, Crab's eye, Jequirity
Active principle: Abrin (toxalbumin/phytotoxin)

Type of Poison

Vegetable/organic irritant poison; toxalbumin (phytotoxin)

Fatal Dose

1-2 decorticated seeds by mouth
90-120 mg abrin by injection

Fatal Period

3-5 days

Judicial Uses

Sui-related cattle poisoning: sui fragments at wound site + histopathology of necrotic lesion = key forensic evidence in criminal cattle-poisoning cases (cheap hide production/revenge)
Artificial conjunctivitis (malingering): powdered seeds rubbed into eyes to simulate eye disease and get medical certificates or avoid duty - detection is medico-legal evidence

Non-Judicial Uses

Arrow poison by tribal communities - crushed seeds applied to arrowheads
Ornamental rosary beads and jewellery - inadvertent puncture/drilling risks abrin exposure

Clinical Features

Seeds swallowed whole: NOT poisonous (intact testa prevents absorption)
Injection/sui route: local painful swelling, ecchymosis, oedema, necrosis, haemorrhagic fluid; systemic - vertigo, cardiac arrhythmia, convulsions, coma, death (resembles viper bite)
Oral (extract/powder): nausea, vomiting, colicky abdominal pain, diarrhoea, haemorrhage, collapse

Mechanism of Action

Abrin = Type II Ribosome-Inactivating Protein (RIP)
A-chain (N-glycosidase): depurinates adenine-4324 of 28S rRNA on 60S ribosomal subunit → irreversible protein synthesis inhibition → cell death
B-chain (lectin): binds galactose residues on cell surface → receptor-mediated endocytosis
Causes haemagglutination and lysis of RBCs
Acts like viperine snake venom: haemorrhagic, cytotoxic, local necrosis

4. FRUITS OF SEMECARPUS ANACARDIUM (Marking Nut / Bhilawan)

Identification

Black, heart-shaped (cone-shaped) fruit with rough projection at base
Thick cellular pericarp; juice: brownish, oily, acrid; turns black on air exposure
Active principles: Semecarpol (0.1%) and Bhilawanol (15-17%)
Also called: Bhilwa, marking nut (used by dhobis as marking ink)

Type of Poison

Vegetable/organic irritant poison; vesicant and corrosive

Fatal Dose

5-10 gm of juice

Fatal Period

12-24 hours

Judicial Uses

Artificial bruise: juice applied to skin produces blisters resembling bruises → used to support false assault charges; forensic differentiation from true bruise is a key court issue
Vaginal introduction as punishment for alleged infidelity → constitutes criminal assault/grievous hurt; medico-legal examination is essential evidence

Non-Judicial Uses

Washermen's (dhobi's) marking ink on clothes - juice turns black on air oxidation
Ayurvedic medicine: Vaidyas administer juice for paralysis and chronic pain treatment

Clinical Features

External: irritation, painful blisters with acrid serum, eczematous eruption, lesion resembles bruise, may ulcerate and slough
Internal (large doses): blisters in mouth and throat, severe gastroenteritis, dyspnoea, tachycardia, hypotension, cyanosis, absence of reflexes, delirium, coma, death

Mechanism of Action

Bhilawanol acts as a direct contact vesicant/irritant (urushiol-like mechanism; same Anacardiaceae family as poison ivy)
Chemical burn on skin/mucous membranes → blister formation
Internally: direct GI mucosal irritation → haemorrhagic gastroenteritis
Systemic absorption → autonomic and cardiovascular toxicity (tachycardia, hypotension, cyanosis)

5. CROTON SEEDS (Croton tiglium / Jamalgota)

Identification

Seeds: oval, blackish-brown with white oily kernel; longitudinal lines on surface
Resemble small castor seeds in size/shape but differ in colour and texture
Oil: brownish, viscid, unpleasant smell, bitter taste
Active principle: Crotin (toxalbumin - irritant and vesicant); crotonoside (glycoside, less poisonous); phorbol esters in oil

Type of Poison

Vegetable/organic irritant poison; toxalbumin

Fatal Dose

4-5 seeds; 1-2 mL (20 drops) of croton oil

Fatal Period

6 hours to 3 days

Judicial Uses

Homicidal food contamination: croton oil mixed in food with homicidal intent; seeds/oil in stomach contents establish corpus delicti in murder investigations
Criminal abortion: oil taken internally or applied vaginally to cervix → constitutes criminal offence; signs of chemical irritation to reproductive tract = forensic evidence

Non-Judicial Uses

Traditional folk purgative: used in small doses in Ayurveda/folk medicine
Arrow poison: wild tribal communities apply oil to arrowheads for hunting

Clinical Features

Hot burning pain from mouth to stomach and anus
Salivation, nausea, copious vomiting
Powerful bloody purging/diarrhoea with burning pain at anus
Vertigo, prostration, collapse, coma, death
External application: burning, redness, vesication (blistering)

Mechanism of Action

Crotin (toxalbumin): inhibits ribosomal protein synthesis (same as ricin/abrin) → cell death
Phorbol esters (in oil): activate protein kinase C → intense local inflammation; also tumour promoter
Direct contact vesicant and irritant on GI mucosa → erosion, haemorrhage, inflammation
Crotonoside (glycoside): additional irritant component

6. SEEDS OF RICINUS COMMUNIS (Castor Bean / Ricin)

Identification

Oval, glossy brown, mottled (speckled) seeds; two sizes (big and small)
Small seeds resemble croton seeds (~1.25 cm × 0.85 cm)
Active principle: Ricin (supertoxic toxalbumin)
Castor seeds: poisonous when raw; SAFE when swallowed whole (intact testa) or cooked
Extracted castor oil does NOT contain ricin (non-poisonous)
Press cake (residue after oil extraction) is highly poisonous (contains ricin)

Type of Poison

Vegetable/organic irritant poison; toxalbumin; supertoxic

Fatal Dose

6 mg of ricin = ~10 seeds (oral)
Injection: ~1 µg/kg body weight

Fatal Period

Several days (multi-organ failure is delayed)

Judicial Uses

George Markov assassination (London, 1978): ricin-filled metallic pellet fired from umbrella tip → detection of ricin in autopsy tissues is cornerstone of bioterrorism/assassination forensic investigation
Bioterrorism: poisoning of water/food or ricin-laced projectiles/aerosols → forensic identification is a national security and criminal matter; CDC Category B agent

Non-Judicial Uses

Castor oil: industrial lubricant, cosmetics, purgative in Ayurveda, nylon manufacturing
Ricin A-chain immunotoxins: experimental targeted cancer therapy research

Clinical Features

Ingestion: burning in throat, salivation, nausea
Copious painful vomiting; colicky abdominal pain
Bloody purging (haemorrhagic diarrhoea); dehydration, cramps
Coma and convulsions preceding death; multi-organ failure (delayed)
Dust inhalation: dermatitis, conjunctivitis, rhinitis, asthma, allergy

Mechanism of Action

Type II RIP (Ribosome-Inactivating Protein) - heterodimeric A-B toxin
B-chain (lectin): binds galactose residues on cell surface glycoproteins → receptor-mediated endocytosis
A-chain (N-glycosidase): cleaves adenine-4324 from 28S rRNA of 60S ribosomal subunit (depurination) → permanently inactivates all ribosomes
Complete inhibition of protein synthesis → cell death in all cell types
No specific antidote exists

7. CAPSICUM SEEDS (Chilli / Lalmirch)

Identification

Seeds: ~0.30 cm long and wide; pale yellow, small, thin, smooth and round
Embryo curved inward on cross-section (key differentiator from dhatura)
Pungent smell and taste (persistent)
Active principles: Capsaicin and Capsicin (acrid, volatile, non-alkaloidal, non-fatal)

Type of Poison

Vegetable/organic irritant; non-fatal in ordinary quantities

Fatal Dose

NOT established - considered non-fatal

Fatal Period

Not applicable

Judicial Uses

Torture/confession extortion: powder introduced into nostrils, eyes, urethra, vagina, or rectum to inflict pain → constitutes criminal assault and torture; medical examination documents chemical mucosal injury
Police chilli bomb/OC (oleoresin capsicum) pepper spray: legally regulated use for crowd dispersal and riot control

Non-Judicial Uses

Universal food condiment (red pepper/lalmirch)
Capsaicin cream: topical analgesic for neuropathic pain, osteoarthritis, post-herpetic neuralgia (medical use)

Clinical Features

Skin: irritation and vesication
Eyes: burning, lachrymation, redness, intense pain
Ingestion: burning sensation from mouth to oesophagus and stomach; irritant gastroenteritis
Inhalation (fumes): irritation of eyes and upper respiratory passages

Mechanism of Action

Capsaicin selectively binds TRPV1 (Transient Receptor Potential Vanilloid-1) receptors on C and Aδ sensory nerve fibres
TRPV1 activation → massive Ca²⁺ and Na⁺ influx → intense burning pain sensation
Depletes Substance P from sensory terminals: initial pain → desensitisation/analgesia with repeated use
Direct membrane irritant on mucous membranes at high concentrations

8. DHATURA SEEDS (Datura stramonium / Thorn Apple)

Identification

Seeds: brownish to black, kidney-shaped, finely pitted and reticulated surface
Embryo curved outward on cross-section (opposite to chilli seeds)
Bitter taste; odourless; larger and thicker than chilli seeds
Fruit: "Thorn Apple" - greenish-grey, apple-shaped with thorny projections
Active principles: (1) Hyoscine (Scopolamine), (2) Hyoscyamine, (3) Atropine

Type of Poison

Vegetable/organic deliriant; anticholinergic alkaloid

Fatal Dose

50-100 crushed seeds (if ingested)

Fatal Period

1-2 days if untreated

Judicial Uses

Criminal stupefaction: crushed seeds mixed with sweet food, pan-beedi deceitfully given before robbery/rape/kidnapping - person is amnesic and helpless; most common DFSA (drug-facilitated sexual assault) agent in India; blood/urine atropine/hyoscine confirms offence
Doping of cigarettes/cannabis: seeds mixed with tobacco and smoked by victim; forensic detection in biological samples is evidence of drug-facilitated crime

Non-Judicial Uses

Himalayan Sadhus/ascetics: consumed for visionary/spiritual/religious experiences (ancient practice)
Hyoscine: used medically as anti-emetic, motion sickness patch, pre-anaesthetic; hyoscyamine: antispasmodic for IBS and urinary frequency

Clinical Features (Classic Anticholinergic Toxidrome - "D's" and mnemonics)

Hot as a hare - dry, hot skin (anhidrosis + fever)
Blind as a bat - mydriasis (dilated pupils), blurred vision, diplopia; red conjunctiva
Red as a beet - flushed face (cutaneous vasodilation)
Dry as a bone - dry mouth (xerostomia), dysphagia, anhidrosis
Mad as a hatter - delirium, hallucinations, agitation, picking at imaginary objects, runs/jumps
Additional: tachycardia, urinary retention, painful urination, drunken gait
Amnesia (stupefaction) - person cannot recall events
Convulsions → coma → respiratory arrest → death if untreated

Mechanism of Action

Hyoscyamine/Atropine/Hyoscine: competitive antagonists at all muscarinic ACh receptors (M1-M5)
Block all parasympathetic effects: decreased secretions (saliva, sweat, bronchial), smooth muscle relaxation, tachycardia, mydriasis
Hyoscine crosses BBB more readily than atropine → delirium, hallucinations, amnesia
CNS: initial excitation → seizures → respiratory depression → death
Decreased gut motility: gastric lavage effective even hours after ingestion
Antidote: Physostigmine 1-2 mg IV (physiological anticholinesterase antidote)

9. GANJA (Cannabis / Cannabis indica)

Identification

Ganja: flowering tops of female Cannabis plant; rusty green colour; characteristic odour; 1-25% THC; smoked in chillum/pipe
Bhang (dried leaves, 15% THC, least potent), Majun (bhang sweetmeat), Charas/Hashish (resin, 25-40% THC, most potent)
Active principle: Tetrahydrocannabinol (THC) - delta-9-THC; fat-soluble
Cystolith test: bear-claw/elephant-tusk crystals under microscopy; CO₂ effervescence with 20% HCl

Type of Poison

Vegetable/organic cerebral deliriant; hallucinogen; narcotic/psychoactive

Fatal Dose

No scientifically authenticated fatal dose
Ganja: ~8 g/kg body weight; Charas: ~2 g/kg; Bhang: ~10 g/kg (Parikh's)

Fatal Period

~12 hours in acute poisoning

Judicial Uses

NDPS Act (India): possession, sale, and use is a criminal offence; urine THC (50-100 ng%) detectable up to 7-8 weeks - legally admissible evidence for prosecution
Stupefying agent: majun/charas used by road poisoners to stupefy victims before robbery/rape; forensic urine/blood THC confirms drug-facilitated crime

Non-Judicial Uses

Sadhus and temple priests: religious/spiritual use to achieve altered/ecstatic states; cultural tradition at Holi/Janmashtami
Medical: dronabinol (THC) for chemotherapy-induced nausea and AIDS wasting; CBD (cannabidiol) for refractory epilepsy; analgesic for neuropathic pain

Clinical Features

Acute (triphasic): Phase 1 - euphoria, relaxation, hilarity, increased sensory perception; Phase 2 - hallucinations, introspection, sedation, conjunctival congestion (red eyes), increased appetite; Phase 3 - tachycardia, palpitations, bronchitis, convulsions, cardiac arrest (overdose)
Chronic: cannabis psychosis (manic, schizophreniform); amotivational syndrome (apathy, poor concentration); cyclical hyperemesis syndrome; suicidal/homicidal tendencies; "running amok"; chronic lung disease, cancers of mouth/larynx, clubbing of digits
Hashish insanity: delusions of grandeur or persecution; sexual jealousy crimes

Mechanism of Action

THC is fat-soluble → stored in adipose tissue → time-release effect (single dose lasts >7 days)
Agonist at CB1 receptors (hippocampus, cortex, cerebellum, basal ganglia) → psychoactive effects
Agonist at CB2 receptors (peripheral immune tissues)
Inhibits adenylate cyclase via Gi-protein coupling → ↓ cAMP → neuromodulation
Modulates GABA, dopamine, acetylcholine, serotonin, noradrenaline, histamine, prostaglandins
Small dose: CNS excitation; large dose: CNS depression → respiratory arrest
