Foundations of Ayurvedic Ophthalmic Therapy

Foundations of Ayurvedic Ophthalmic Therapy

Aschotana and Anjana are essential therapeutic modalities in Ayurveda used to address a wide spectrum of ocular disorders, ranging from irritation and itching to inflammatory conditions. These practices, detailed in the 23rd chapter of Ashtanga Hridaya Sutrasthana by Acharya Vagbhata, focus on the direct administration of medicated liquids and salves to restore eye health by balancing the internal Doshas.

Aschotana: The Application of Eye Drops

Aschotana involves the application of liquid medication directly into the eyes. This therapy is highly effective for alleviating symptoms like eye pain, pricking sensations, redness, excessive tearing, and itching.

• Temperature Guidelines: The choice of temperature is determined by the specific Dosha imbalance:

• Vata: Warm liquids are preferred.

• Kapha: Lukewarm liquids are recommended.

• Pitta and Rakta (Blood): Cold liquids are necessary to provide relief.

• Procedural Steps: The patient should lie in a breeze-free environment. The physician uses their left hand to hold the eye open while carefully administering 10–12 drops from a seashell or wick, positioned two finger-widths above the inner corner of the eye. Afterward, the eyes are cleansed, and a gentle fomentation (warm or cold depending on the Dosha) is applied.

Anjana: The Application of Eye Salve

Anjana, or collyrium, is a sophisticated treatment suited for patients who have already undergone bodily purification (such as Vamana or Virechana) and show signs of ripened ocular conditions like thick discharge or severe itching.

• Three Therapeutic Categories:

• Lekhana (Scraping): Used to clear blockages; typically prepared with pungent, bitter, or salty herbs.

• Ropana (Healing): Focused on restoration; prepared with bitter herbs.

• Prasadana (Soothing): Designed to clarify vision; prepared with sweet, cooling substances.

• Application Logic: The form of the Anjana—Pinda (pill), Rasakriya (gel), or Churna (powder)—is selected based on the severity of the Dosha imbalance. The physician utilizes specialized rods made of gold, silver, iron, or copper, depending on the desired therapeutic outcome.

Best Practices and Contraindications

The timing and physical condition of the patient are critical for the safety and success of these treatments.

• Timing: Generally, Anjana should be applied in the morning or evening. Application at midday, during sleep, or in extreme heat/cold is discouraged, as it may exacerbate Dosha imbalances or lead to further eye complications.

• Contraindications: Therapy should be avoided in cases of fear, fever, indigestion, intoxication, or immediately after a head bath or exposure to excessive smoke.

• Post-Therapy Care: After administration, the patient should gently rotate the eyeballs and massage the lids to ensure the medicine spreads. The eyes must be thoroughly washed after the drug's activity ceases to prevent irritation from leftover residue. If the eyes feel fatigued by strong medication, a Pratyanjana (counter-collyrium)—typically a cold powder—is applied to soothe the area.

In summary, Aschotana and Anjana represent a disciplined approach to ocular care, emphasizing that proper technique, precise herbal formulation, and timing are vital to ensure the eyes, which are governed by the Agni (Fire) element, remain healthy and clear.
