Abstract: A topical composition is disclosed for reducing a urushiol-induced allergic response and the dermatitis associated therewith. The composition is a preparation having an acorn derivative and a nontoxic dermatologically acceptable aqueous dispersion material. The acorn derivative is acorn ash, acorn mash, roasted acorn, or acorn extract and comprises about 0.1 to 50 percent by weight of the treating preparation. After the initial preparation, preservatives are then added. Optionally, additional ingredients such as surfactants and emulsifying agents, antihistamines, topical anesthetics, colloidal oatmeal, topical antipruritics, astringents, and emollients may be added to the aqueous acorn dispersion. With processing varied according the examples provided, the ingredients are combined so as to create sprays, creams, gels, ointments, and lotions.
