Abstract
A method for treating rhus dermatitis caused by exposure to urushiol is provided, comprising the step of topically applying a therapeutically effective amount of a soluble manganese salt to the affected area of the skin. The manganese compound penetrates the pores of the skin and acts a chelating agent on the urushiol molecule, deactivating its toxicity. A detoxification agent for urushiol is also provided, comprising a composition containing a soluble salt of manganese, such as an aqueous or alcohol solution, wherein the weight percent of manganese in said composition is a therapeutically effective amount, such as between 0.01% and 10.0% manganese. The detoxification agent is also useful as a means of preventing rhus dermatitis when applied to the skin in an appropriate base.
