Castellani Paint is a traditional pharmacy compound, still used mainly as a topical antifungal solution.
Magenta (basic fuchsin) makes a dark purple solution that appears red on the skin and can stain. It has some local anesthetic, bactericidal and fungicidal properties.
It has also been reported to stimulate granulation tissue and epithelialization.
Magenta free solution is also available, but has a weaker beneficial effect in comparison.
Ingredients: Ethanol (solvent with cooling and antiseptic properties), Boric acid (antiseptic and antifungal), Phenol (a caustic agent, which at lower concentrations inhibits nerve endings and helps relieve itch), Acetone (solvent with cooling and cleansing properties), Resorcinol (an important constituent with few beneficial effects).

Castellani's paint was perfected in 1905 by Aldo Castellani (1878-1971), an Italian physician and a specialist in tropical diseases. Castellani's paint is an excellent preparation for tinea cruris and moniliasis of intertriginous areas.1 It is effective in pustular dermatoses of the hands and feet,2 and has also been recommended for pruritus ani and pruritus vulvae.3 Colorless Castellani's paint may be used to reduce secondary bacterial contamination in onycholysis and in chronic paronychia.4
Castellani's paint dramatically improves inflamed skin around the the groin, particularly in patients with a history of long-term topical steroid application. Applying Castellani's paint is an effective way to dry oozing lesions, particularly in the groins and the toe webs.9
