Parthiva · mineral origin · Uparasa
SHODHANA — NO MINERAL DRAVYA IS USED RAW
Boiled in ardraka swarasa or in agastya patra swarasa by the dola yantra method, repeatedly. As with haratala, this changes the form and removes gross impurity; the arsenic remains.
TRADITIONAL VIEW, WITH SAFETY LIMITS
Hindi name: Mainsil
What the texts say Manahshila does
What the evidence says. Toxicological literature is substantial for realgar across both Ayurveda and traditional Chinese medicine. Efficacy evidence for the classical preparations is not established.
Side effects and limits
This is arsenic, as haratala is. Realgar is used in traditional Chinese medicine as well and arsenic poisoning from both traditions is documented. Realgar converts to more soluble and more toxic arsenic species on exposure to light and air over time, which is a storage problem specific to this mineral.
Avoid or ask first: Pregnancy and breastfeeding.; Children.; Renal or hepatic impairment.; and more below.
A traditional classification, not a recommendation. The full safety record is below.
AS THE CLASSICAL TEXTS AND THE API PRESCRIBE

Never given alone. It appears in named yogas — Shwasa Kuthara rasa among them — prepared by a qualified practitioner.
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, guna, virya, vipaka and karma are recorded as the classical texts give them, with the text and section named so a student can open the book and check.
Constantly confused with Haratala. Manahshila is the RED disulphide; Haratala is the yellow trisulphide. Both are arsenic and a shop will supply either under either name.
Arsenic disulphide, As2S2 (also written As4S4). A red arsenic mineral.
A WAY TO REMEMBER IT
Manah-shila is mind-stone. Realgar is from the Arabic rahj al-ghar, powder of the mine.
Manahshila is an uparasa used in classical yogas for shwasa and kasa. As with haratala the texts class it as a poison requiring shodhana.
Constituents. Arsenic disulphide, As2S2 (also written As4S4). A red arsenic mineral.
| Status | Toxicological literature is substantial for realgar across both Ayurveda and traditional Chinese medicine. Efficacy evidence for the classical preparations is not established. |
| The honest gap | Mineral and animal dravya are far less studied than plant dravya, and what study exists is chiefly characterisation and toxicology rather than clinical efficacy. |
This is arsenic, as haratala is. Realgar is used in traditional Chinese medicine as well and arsenic poisoning from both traditions is documented. Realgar converts to more soluble and more toxic arsenic species on exposure to light and air over time, which is a storage problem specific to this mineral.
| Contraindications | Pregnancy and breastfeeding. Children. Renal or hepatic impairment. Any use outside a qualified Rasashastra practitioner's hands. |
| Interactions | Any drug prolonging the QT interval. Chelating agents — the treatment for arsenic toxicity. Any nephrotoxic or hepatotoxic drug — additive burden. |
| Pregnancy and breastfeeding | Absolutely contraindicated. |
