2. Introduction Gairika is the second mineral drug of uparasa group. It is identified as mineral ‘Haematite’ or ‘Ochre’. Haematite is the mineral form of iron oxide (Fe,O,), one of several iron oxides. It is colored black to steel or silver-grey, brown to reddish brown, or red. It is mined as the main ore of iron.
Varieties include ‘kidney ore’, ‘martite (pseudomorphs after magnetite), ‘iron rose’ and ‘specularite’ (specular hematite). While the forms of hematite vary, they all have a rust-red streak. Hematite is harder than pure iron, but much more brittle.

3. SYNONYMS Raktadhatu – red in color, Lohadhatu – iron red in color, Gaireya, Girimruttika, Girika, Gairika, Girimrudbhava

4. Geographical Distribution Huge deposits of hematite are found in banded iron formations. Grey hematite is typically found in places where there has been standing water or mineral hot springs, such as those in ‘Yellowstone National Park’ in the United States. The mineral can precipitate out of water and collect in layers at the bottom of a lake, spring, or other standing water. Hematite can also occur without water, however, usually as a result of volcanic activity.

5. Clay-sized hematite crystals can also occur as a secondary mineral formed by weathering processes in soil, and along with other iron oxides or oxyhy- droxides such as goethite, is responsible for the red color of many tropical, ancient or otherwise highly weathered soils.
