Donovan's solution is an inorganic compound prepared from arsenic triiodide and mercuric iodide.[1] Despite its name, it is a compound and not a solution.
Method
Donovan's solution can be prepared by mixing arsenic triiodide, mercuric iodide, and sodium bicarbonate in aqueous solution.[2][3]
Cooley's cyclopædia of practical receipts and ... information on the arts, manufactures, and trades gives a more complex method.[4]
Uses
The solution been used in veterinary medicine to treat chronic diseases of the skin[3] and as a folk remedy.[5] It was used during the 19th century to treat lepra vulgaris[6] and psoriasis[7][8] in humans, taken internally.
