What is Zinc?
Not every Ayurvedic "herb" grows in the ground. Zinc, called Yashada or Jasada in Sanskrit, is one of the metals classical Ayurveda turns into medicine, and it is used almost entirely in one processed form: Yashad Bhasma, a fine ash made by purifying and calcining the metal.
The Bhavaprakash Nighantu (Varga 7, verses 111 to 113) describes it as cooling and especially useful in Pitta conditions. Its three listed uses are eye health, diabetes and wound healing.
The key point for a newcomer: raw zinc is never the medicine. The classical texts insist that it be properly purified and processed first, and the Sharangadhara Samhita (Madhyama Khanda, Chapter 11) sets out those purification (Shodhana) and calcination (Marana) procedures alongside those for silver, copper, iron and other metals.
Benefits of Zinc
Classically, Zinc is bitter and astringent (Tikta, Kashaya Rasa), light (Laghu), cold in potency (Sheeta Virya) and pungent after digestion (Katu Vipaka). Cooling and drying, it is a Pitta remedy.
Eye health
The Bhavaprakash Nighantu lists it as beneficial for the eyes (Netrya), and Yashad Bhasma is used in eye diseases. The eyes are a classical seat of Pitta, so a cooling mineral fits.
Diabetes
It is listed as anti-diabetic (Pramehaghna), acting against Prameha, the classical group of urinary disorders that includes diabetes.
Wounds and skin
It is wound-healing (Vranaropana) and linked to skin disorders. The Ashtanga Hridaya (Sutrasthana, Shastrakarma Vidhi) even advises covering wounds with a lot of fat and Kapha with thin sheets of copper, iron, zinc or lead.
How to Use Zinc
In Ayurveda, Zinc is taken only as a properly prepared bhasma, prescribed by a practitioner. Our sources give no home dose.
| Form | Dose | Best For | When to Take |
|---|---|---|---|
| Yashad Bhasma | Practitioner-set | Eye diseases, diabetes, wound healing | As prescribed |
| Thin zinc sheet over a wound | External only | Wounds with excess fat and Kapha, per the Ashtanga Hridaya | Classical surgical practice |
Buy only from manufacturers who follow classical purification (Shodhana) and calcination (Marana). An unprocessed or poorly processed metal preparation is exactly what the texts warn against.
Safety & Side Effects
- Processing is everything: the Bhavaprakash Nighantu states that zinc must be properly purified and processed before use. Never take raw or improperly prepared metal.
- Supervision: metal-based bhasmas belong under a qualified practitioner, with a set dose and course.
- Diabetes medication: if you take medicine for blood sugar, tell your doctor before adding Yashad Bhasma, since its classical use targets the same condition.
- Drug interactions and overdose: our sources document none specifically, which is a gap rather than reassurance.
Recommended: Start Here
The one sensible starting point for Zinc in Ayurveda is a consultation, then a properly made Yashad Bhasma at the dose your practitioner sets.
Why not self-dose: this is a processed metal. The classical texts make proper purification a condition of use, and the right amount depends on what you are treating.
What to look for: a reputable Ayurvedic manufacturer that states classical Shodhana and Marana processing on the label.

Do not take any metal bhasma without a qualified practitioner, and tell your doctor if you are on diabetes medication.
Zinc vs Other Herbs & Supplements
| Comparison | Yashad Bhasma | Alternative | Verdict |
|---|---|---|---|
| Yashad Bhasma vs other metal bhasmas | Cooling; eyes, diabetes, wounds | Silver, copper, iron, lead, tin and others, purified by the same Sharangadhara procedures | Each metal has its own indications; a practitioner chooses by condition |
| Zinc vs Willow | Cooling mineral for Pitta, used as an ash | Cooling bark for Pitta, used as a decoction | Both cool Pitta; Willow is a plant you can use more simply, Zinc needs supervision |
Zinc for Specific Populations
Pregnancy & Nursing
Our sources give no safety data for Yashad Bhasma in pregnancy or nursing. Avoid it unless a qualified practitioner directs otherwise.
Children
No child dosing is recorded. Metal preparations should not be given to children without professional supervision.
Elderly
Its classical uses for eyes, diabetes and slow-healing wounds are common concerns in later life. Any use should be supervised and checked against existing medications.
Athletes
Our sources say nothing about athletic use.
Frequently Asked Questions
What is Yashad Bhasma?
It is zinc that has been purified (Shodhana) and calcined (Marana) into a fine ash, the form in which Ayurveda uses the metal.
Is Yashada the same as Jasada?
Yes. Yashada, Jasada and Kharpara are Sanskrit names for zinc; in Hindi it is Jasta.
Is Zinc heating or cooling in Ayurveda?
Cooling. It has a cold potency and is especially used in Pitta conditions.
Can I take a regular zinc supplement instead?
Our sources describe only the classical bhasma, not modern zinc supplements. The two are prepared very differently, so ask your doctor or practitioner which, if either, suits you.
