1. "Like cures like" (Similia Similibus Curentur) - A substance that causes symptoms in a healthy person can, in highly diluted form, treat similar symptoms in a sick person.
2. Law of Infinitesimals - The more a substance is diluted (through a process called "potentization" - serial dilution with vigorous shaking/succussion), the more potent it becomes therapeutically.
3. The Vital Force - Homoeopathy holds that disease arises from a disturbance in the body's "vital force" (life energy), and remedies work by stimulating this force to heal.
4. Individualization - Treatment is tailored to the individual's complete symptom picture - physical, mental, and emotional - rather than just the disease label.

• Potencies (e.g., 6C, 30C, 200C, 1M) - levels of dilution
• Repertory - an index of symptoms matched to remedies
• Materia Medica - the pharmacopoeia of homoeopathic remedies
• Miasms - Hahnemann's theory of chronic disease (Psora, Sycosis, Syphilis)
• Constitutional treatment vs. acute prescribing

The Kali Group in Homoeopathy

What is the Kali Group?

Doctrine of Signature / Physiology of Potassium

• Potassium draws water to where it is most concentrated - explaining the oedema and hydremia tendencies
• Reduction of muscle irritability - explains general debility, weakness, and paralysis in Kali remedies
• Strong affinity for fibrous and solid tissues, ligaments, joints, back, and blood corpuscles

Common (Group) Characteristics of ALL Kali Remedies

Constitution

• Flabby, fatty, pale individuals with tendency to obesity
• Anaemic with tendency to weakness and exhaustion
• Increased tendency to oedema and water retention
• Affinity for fibrous tissues - joints, ligaments, tendons

Mental/Emotional Generals (Kali Personality)

• Deep insecurity and fear of being alone or abandoned
• Strong need for relationships and dependency on family/loved ones
• Conscientious, responsible, duty-bound individuals
• Rigid thinking, conservative, moralistic, and rule-following
• Fear of the future, anticipatory anxiety, fear of death
• Anxiety about health of self and family members
• Family-oriented - the "householder type" (Kent)
• Suppression of emotions; difficulty expressing feelings
• Desire for company but also irritability with company
• Hypersensitivity to pain, noise, and touch

• Childhood: Dependence on parents; fear of separation
• Adulthood: Core insecurity leads to vulnerability, anxiety with desire for company
• Old Age: Multiple organ involvement (heart, kidneys, lungs); pathologies with water retention or dryness; degenerative/destructive conditions

Physical Generals

• Great weakness and debility - feels better lying down
• Aggravation at 2-3 AM (classic Kali time modality - esp. Kali carb)
• Aggravation from cold, cold air, cold weather
• Amelioration from warmth
• Sticking, stitching, stabbing pains - this is a hallmark of the Kali group
• Tearing, cutting, neuralgic pains; pains in small, pin-point areas
• Pulling, stitching, shifting pains
• Choreic movements, twitchings, jerkings, and convulsions common to all Kali salts
• Hemiplegia and paralysis - all Kali salts can produce paralytic conditions
• Power to arrest abnormal secretions - mucous, serous, perspiration, haemorrhage

Discharges

• Discharges tend to be thick, stringy/ropy, tenacious (especially Kali bich)
• Mucous membranes prominently affected
• Green-yellow and bloody, foul-smelling muco-pus: Kali iod, Kali phos
• Haemorrhagic remedies: Kali carb and Kali phos (phosphorus content adds haemorrhagic tendency)
