SHODHANA — NO MINERAL DRAVYA IS USED RAW
Triturated with godugdha and dried, repeatedly.
TRADITIONAL VIEW, WITH SAFETY LIMITS
Hindi name: Geru
What the texts say Gairika does
What the evidence says. No modern clinical evidence establishes an effect on any named condition.
Side effects and limits
Iron oxide is poorly absorbed and is among the least toxic mineral dravya. Natural ochre can carry lead and arsenic from its source, which is a sourcing question.
Avoid or ask first: Iron overload states, as a precaution.; Unsourced or industrial pigment.
A traditional classification, not a recommendation. The full safety record is below.
A Samhita can only be read forwards, from the group to its members. This is the same list read backwards.

Ferric oxide, Fe2O3, with clay. The red earth pigment.
A WAY TO REMEMBER IT
Gairika is from giri, a mountain — the earth that comes off the hill. Ochre is from the Greek ochros, pale yellow, for the unburnt form.
Gairika is used in raktapitta and in burns, and is one of the oldest pigments and medicines in continuous use anywhere.
Constituents. Ferric oxide, Fe2O3, with clay. The red earth pigment.
| Status | No modern clinical evidence establishes an effect on any named condition. |
| 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. |
Iron oxide is poorly absorbed and is among the least toxic mineral dravya. Natural ochre can carry lead and arsenic from its source, which is a sourcing question.
| Contraindications | Iron overload states, as a precaution. Unsourced or industrial pigment. |
| Interactions | No specific drug interaction is documented for this dravya. Any oral drug taken at the same time — iron oxide can bind. Separate by two hours. |
| Pregnancy and breastfeeding | Not established as safe internally. |
