Treatment of Atopic Dermatitis, Dermatophytes, and Syphilis by Indigenous Peoples Prior to 1850.

The Iroquoian and Algonquian-speaking Peoples of North America discovered numerous natural treatments to dermatological conditions long prior to European settlement. Anthropological evidence suggests that treatments for atopic dermatitis, dermatophyte infections, and syphilitic lesions were derived from Sassafras albidum, genus Salix trees, and Sassafras officinale. Literature suggests these medicinal properties are attributed to the naturally abundant safrole, salicylic acid, and ascorbic acid in these flora. Numerous instances of these natural medicinal discoveries later being implemented into European literature reaffirms the impact of Indigenous medicine on contemporary dermatology.
