Chemistry in the Vagbhata.
A typical example is contained in the following recipe:
Sulphate of copper, red ochre, realgar, orpiment sulphate of iron, &c., are recommended for external application for genital sores.
Preparations of Gold, Silver, Copper, Iron and Lead
Gold, copper, silver, iron or tin are to be taken with the myrobalans, rock-salt and honey, &c.
Gold, silver, copper and iron are to be taken in conjunction with bitumen and milk.
Take 30 parts of lead, 5 parts of sulphur, 2 parts of copper and orpiment each, 1 part of tin and 3 parts of stibium. Now roast them in a closed crucible.
[Here as well as in the preceding sloka, we have distinct mention of अन्धमूषा or a crucible with the lid on. This is one of the preparations which can be brought into line with those of the Tāntric and Iatro-chemical periods.]
Preparation of Alkali and Caustic Alkali
[As Vāgbhata borrows his method of preparation of alkali almost word for word from Susruta, it is quite superfluous to reproduce it here.]
Use of Mercury
Take equal parts of mercury and lead and make them up into a collyrium with their equal weight of stibium and camphor. [This is perhaps the only instance in which the mention of mercury is found.]
- "स्रोतोञ्जन" Srotonjana is evidently stibnite or the native sulphide of antimony (See p. 53); Dutt translates it, we know not on what grounds, as calx-spar.
