Mica for Conjunctivitis: Does It Work?
Does Mica (Abhrak) help with conjunctivitis? Only as a minor classical ingredient. The Sushruta Samhita lists mica (abhra) among the cooling ingredients for Pitta-type conjunctivitis. Raw mica is never a home eye remedy.
Ayurveda calls conjunctivitis Abhishyanda and our condition sources describe it chiefly as aggravated Pitta in the eyes. Mica's classical profile is cooling: sweet, bitter and astringent in taste, cold in potency and sweet after digestion.

How Mica Helps with Conjunctivitis
Ayurveda places the heat of conjunctivitis in Alochaka Pitta, the part of Pitta that governs sight. Red, burning, weeping eyes call for cooling.
Mica's properties
Mica is sweet, bitter and astringent (Madhura, Tikta, Kashaya), light and unctuous, cold in potency (Sheeta Virya) and sweet after digestion. That is a cooling, soothing profile, which explains why it appears among Pitta-type eye ingredients.
Mineral medicine, not a raw mineral
Mica is one of the most important minerals in Rasa Shastra, the Ayurvedic branch of mineral medicine. It is used as an ash (Bhasma) made through long purification and repeated heating. The Sharangadhara Samhita describes these purification and calcination steps in detail.
In the eye formula, mica is one of many ingredients, alongside cardamom, blue lotus, padmaka and cane. Our sources give no modern research on mica for conjunctivitis.
How to Use Mica for Conjunctivitis
For conjunctivitis, mica has no home use. Its eye role is as one ingredient in a classical Pitta-type preparation, and as a medicine it is taken only as a properly prepared ash under supervision.
| Form | Amount | For Conjunctivitis | Guidance |
|---|---|---|---|
| Classical Pitta-type eye preparation with mica | Not specified in our sources | Red, burning eyes | Practitioner only |
| Abhrak Bhasma (internal) | As prescribed | Not an eye treatment in our sources | Only under a Rasa Shastra practitioner |
| Raw mica | Never | None | Never in the eye, never swallowed |
The home approach instead
Our condition sources centre home care on a well-strained Triphala eye wash, rose water to soothe, and ghee to calm the heat within.
Frequently Asked Questions
Can I use mica for pink eye?
No. Mica appears in one classical eye formula as a minor ingredient. Raw mica must never go in the eye.
Is Abhrak Bhasma an eye medicine?
Our sources describe it as a major rejuvenative used in respiratory disease, chronic fevers, anemia and debility, not as an eye treatment. Take it only under a practitioner.
Who should avoid mica preparations?
Avoid them in pregnancy, nursing and childhood unless a practitioner directs otherwise, and buy only from a reputable Ayurvedic pharmacy.
Which herbs share mica's eye formula?
Green Cardamom, Wild Himalayan Cherry and Willow each have their own page. For an everyday option, see Amla.
Recommended: Start Mica for Conjunctivitis
If you want to start the Ayurvedic approach to conjunctivitis today, mica is not the place to begin. It is a minor classical ingredient and a supervised mineral medicine.
Best first step: have the eye checked, then use the home care our condition sources describe: a well-strained Triphala eye wash and pure rose water.

Safety: never put raw mica or any mineral in your eye, take Abhrak Bhasma only under supervision, and see a doctor for vision changes or severe pain.
Safety & Precautions
Mica is a mineral medicine, and its safety depends almost entirely on how it is prepared. Treat it as practitioner-guided, not as an over-the-counter supplement.
Preparation Is the Safety Step
- Never raw. Only properly purified (Shodhana) and calcined (Marana) Abhrak Bhasma is used internally.
- Higher grade, safer ash. The Bhavaprakash Nighantu states that Bhasma processed through more Putas is both more effective and safer.
- Source carefully. Buy only from a reputable Ayurvedic pharmacy, and use it under the supervision of a practitioner who works with Rasa Shastra medicines.
What Our Sources Do Not Cover
Our sources list no specific contraindications, drug interactions or overdose signs for Abhrak Bhasma, and no modern safety studies. That gap is a reason for caution, not reassurance.
If you are pregnant, nursing, giving it to a child, or taking prescription medicines, do not use it without a practitioner and your doctor both knowing. For anemia, get a blood test to confirm the type before you start.
