Compound salicylic collodion (Collodium Salicylicum Compositum) is a paint for corns and warts made of salicylic acid and extract of Indian hemp dissolved in collodion. The British Pharmaceutical Codex of 1907 gives it as salicylic acid 12 parts and extract of Indian hemp 2 parts, made up to 100 with acetone collodion, under the other names Collodium Callosum and "Corn Solvent", and says it "is used as a corn and wart 'solvent'".[1]: 273
King's American Dispensatory (1898) notes that "A combination of cannabis, collodion, and salicylic acid has been used to destroy corns, the extract of the hemp acting as an anodyne."[2] In the United States the National Formulary made its Collodium Salicylici Compositum with the fluid extract of cannabis, according to the Dispensatory of the United States of 1918.[3]
Formulas printed for proprietary corn cures also put cannabis in collodion with salicylic acid. Charles W. Oleson's collection of published formulas for patent medicines gives "Liebig's Corn Cure" as five parts of extract of Cannabis indica, 30 of salicylic acid and 240 of collodion, painted on for four nights and mornings: "The collodion protects the corn from irritation and rubbing, while the extract of cannabis indica acts as an anodyne, and the salicylic acid dissolves and disintegrates the corn."[4]: 110 The same book prints "Rogers's Excelsior Corn Cure" from the Medical World, of fluid extract of Cannabis indica, morphine sulphate and salicylic acid in collodion.[4]: 148
