SHODHANA — NO MINERAL DRAVYA IS USED RAW
Bhavana with the juice of ardraka, nirgundi or kumari, repeatedly, by the standard method for the mercury minerals. The shodhana does not remove the mercury and the texts do not claim it does.
TRADITIONAL VIEW, WITH SAFETY LIMITS
Hindi name: Giri sindoor
What the texts say Girisindura does
What the evidence says. Traditional use is documented in the Rasashastra texts. Modern evidence about this dravya is largely toxicological rather than therapeutic.
Side effects and limits
This is a mercury compound. Mercuric oxide is substantially more soluble and more acutely toxic than mercuric sulphide, which is what Hingula is - so Girisindura is the more dangerous of the two and the texts treat it as a specialist article. Mercury poisoning from Ayurvedic preparations is documented by regulators outside India, including the CDC. Anyone pregnant, on medication or managing a diagnosed condition should speak to a doctor or a qualified practitioner first.
Avoid or ask first: Absolutely not used in the raw, unprocessed state.; Not used where there is kidney disease.; Not used at all outside specialist Rasashastra practice.
A traditional classification, not a recommendation. The full safety record is below.
AS THE CLASSICAL TEXTS AND THE API PRESCRIBE
| Shuddha churna | 15–30 mg, within a yoga, specialist use only |
| Anupana | Madhu |
| Kala | As the yoga directs |
A quantity for the processed article inside a compound preparation, prescribed by a practitioner trained in Rasashastra. Never the raw mineral.
Reported from Sharangadhara Samhita and the Ayurvedic Pharmacopoeia of India. Laisha states what the texts prescribe; it does not recommend. No quantity here is adjusted for a particular person — not for agni, koshtha, bala, age, pregnancy, kidney or liver function, or anything already being taken.
| Rasa | KatuTiktaKashaya |
| Guna | LaghuTikshna |
| Virya | Ushna |
| Vipaka | Katu |
| Prabhava | Named in the texts as a rasayana and for kushtha, in the same register as the other mercury preparations. |
| Doshakarma | Kaphavatahara. |
Katu, tikta and kashaya with ushna virya and katu vipaka.
These are the actions the classical texts record. They are statements about what the tradition holds, and this library does not restate them as findings about a human body.
| Upayukta anga | Shuddha girisindura, and only within a yoga |
| Why it matters | The processed article, never the raw mineral. A lot received raw is a different material from the one the formula names. |
Girisindura is a natural mineral; Rasasindura is a prepared mercury-sulphur compound made in the laboratory. The names are close and the articles are not the same.

Red lead (sindura, lead tetroxide) is sold as Girisindura and the two names are close enough that the substitution is often not deliberate. That is a serious error: one is a mercury compound and the other is lead, and both are poisons of quite different kinds. A red powder sold under either name should be assayed and not assumed.
Given as a naturally occurring red mercury compound, usually read as mercuric oxide, HgO, and distinguished in the texts from Hingula, which is the sulphide. Some authorities read Girisindura as a prepared rather than a natural article.
A WAY TO REMEMBER IT
Giri is a mountain and sindura is vermilion - the red earth of the hills. The same word sindura names red lead, which is precisely why the two get confused in the market.
Girisindura is listed among the sadharana rasa of the Rasa Ratna Samuccaya and distinguished there from Hingula. That is what the tradition records.
Constituents. Given as a naturally occurring red mercury compound, usually read as mercuric oxide, HgO, and distinguished in the texts from Hingula, which is the sulphide. Some authorities read Girisindura as a prepared rather than a natural article.
| Status | Traditional use is documented in the Rasashastra texts. Modern evidence about this dravya is largely toxicological rather than therapeutic. |
| Suggested | The dravya has a defined place and a defined shodhana in the classical Rasashastra literature, and the processed form has a pharmacopoeial standing in India. That is a standard for the material, not evidence of an effect in a body. |
| Not established | There is not enough good clinical evidence to establish an effect on any named health condition. Long traditional use is not a substitute for that evidence, and this library does not present it as one. |
| The honest gap | Published analyses of preparations containing this dravya rarely record whether shodhana was performed or how, so a result cannot be attributed to the processed article rather than the raw mineral. |
This is a mercury compound.

| Contraindications | Absolutely not used in the raw, unprocessed state. Not used where there is kidney disease. Not used at all outside specialist Rasashastra practice. |
| Interactions | No specific drug interaction is documented for this dravya. That is the honest state of the evidence, not a statement that none exists - the mineral dravya have almost never been studied for interaction with modern medicines. |
| Pregnancy and breastfeeding | Not used in pregnancy. Mercury crosses the placenta and is a known developmental neurotoxin; no quantity has been established as safe. |
