नस्य कर्म (Nasya Karma)

Definition (परिभाषा)

"नासा हि शिरसो द्वारं तेन तद्व्याप्य हन्ति तान्" (Charaka Samhita, Siddhisthana 9/89)

Classification (भेद) - 5 Types as per Charaka

1. Navana Nasya (नावन नस्य)

• Administration of medicated oils or ghee (Sneha Dravyas) through the nose
• Also called Pratimarsha when done daily in small doses

2. Avapida Nasya (अवपीड नस्य)

• Fresh plant juice or paste is squeezed and instilled
• More potent than Navana
• Used in acute Kapha conditions

3. Dhmapana / Pradhamana Nasya (प्रधमन नस्य)

• Dry powder (Churna) is blown into the nose using a tube
• Most powerful Shodhana type
• Used in unconsciousness, epilepsy, heavy Kapha disorders

4. Dhuma Nasya (धूम नस्य)

• Medicated smoke is inhaled through the nose
• Used for Kaphaja conditions, hoarseness, rhinitis

5. Pratimarsha Nasya (प्रतिमर्श नस्य)

---

Important Classical References

---

Mechanism of Action (Modern Perspective)

• Nasal mucosa has rich vascular and lymphatic supply
• Drugs absorbed via olfactory epithelium reach the brain directly (bypassing blood-brain barrier)
• Stimulates hypothalamus and limbic system
• Drains paranasal sinuses by mucociliary clearance
• Reflex stimulation via trigeminal nerve

---

Important Exam Points (Short Notes / MCQs)

• Nose = Shirodwara (gateway of head) - Charaka
• Pratimarsha Nasya = 2 drops, can be done daily
• Pradhamana = powder blown = strongest Shodhana
• Best Nasya drug = Anu Taila
• Contraindicated in pregnancy, acute fever, immediately post-bath
• Ardita (facial palsy) = classic indication
• Manyastambha (neck stiffness) = classic Vata indication
• Time for Nasya = not at night, not on cloudy day

Method of Preparation (निर्माण विधि) - The 10-Cycle Process

STEP 1: All herbs taken in equal quantities
         ↓
STEP 2: Mixed in 100 times pure RAIN WATER
         ↓
STEP 3: Boiled until reduced to 1/10th = Kwatha (Decoction)
         ↓
STEP 4: 1/10 sesame oil added to the decoction
         ↓
STEP 5: Boiled on mild fire (Mridu Agni) until only oil remains
         ↓
STEP 6: THIS PROCESS IS REPEATED 9 MORE TIMES (Total 10 cycles)
         ↓
STEP 7: At the 10th (final) cycle, equal quantity of GOAT'S MILK
         is added along with decoction and oil
         ↓
FINAL OIL: Deeply potentised Anu Taila

• Each cycle increases potency and penetrating ability
• Active phytochemicals get progressively concentrated in the oil
• Oil becomes increasingly "Sukshma" (subtle) - able to penetrate fine Srotas
• This is ancient Ayurvedic potentisation - analogous in principle to homeopathic potentisation

Pharmacological Actions (कर्म / Guna)

Ayurvedic Properties

Detailed Actions (Karma)

1. Shodhana (Purificatory Action)

• Mobilises accumulated Kapha and Vata Doshas from head, chest, throat, palate

• Herbs like Vidanga, Kantakari, Bilva contribute to this

2. Brumhana (Nourishing / Anabolic Action)

• After Shodhana (cleansing), the oil nourishes the same tissues
• Strengthens muscles, ligaments, and tendons of neck, shoulders, chest
• Shatavari, Jivanti, Sthira, Bala provide this Brumhana action
• Beneficial in Manyastambha (cervical stiffness), Ardita (facial palsy)

3. Snehana (Oleating Action)

• Sesame oil base provides deep tissue oleation
• Prevents dryness of nasal mucosa, throat, eyes
• Pacifies Vata in Shirogata region

4. Indriya Bala Vardhana (Sensory Organ Strengthening)

• Increases the efficiency and acuity of Nasa (nose), Netra (eyes), Karna (ears)
• Nourishes the Olfactory epithelium - improves sense of smell
• Regular use improves vision, hearing, and voice quality
• Herbs: Chandana, Utpala, Padmakesara act on Alochaka Pitta (visual function)

5. Rasayana (Anti-aging / Rejuvenative Action)

• Clears sinuses - excellent in Peenas (sinusitis), Pratishyaya (rhinitis)
• Mucociliary clearance stimulation
• Anti-inflammatory effect on nasal mucosa

---

Modern Pharmacological Perspective

Why does Anu Taila work? (Mechanism)

Nasal instillation
        ↓
Olfactory epithelium absorption
        ↓
Direct entry into CNS (bypasses blood-brain barrier)
        ↓
Limbic system and hypothalamus stimulation
        ↓
Neuromodulatory effects

• Acts as an emulsifier and mucosal protectant
• Its small fat globules enhance nasal mucosal absorption
• Lighter than cow's milk, less irritating to nasal passages
• Enhances penetration of oil into Sukshma Srotas
