  • Rhus dermatitis treatment composition and method
    Patent number: 6022565
    Abstract: A poison ivy (and related dermatitis) treatment composition and method in which a novel composition containing a combination of active ingredients gives new and unexpected results over compositions of the prior art. The inventive composition includes three essential ingredients: extract (fresh sap) of jewelweed (Impatiens species); fresh sap of plantain leaf; and an aqueous colloidal dispersion of subdivided whole oat grains. It is believed that the amphiphilic nature of the aqueous colloidal oat dispersion both preserves the activity of the plantain and jewelweed enzymes, as a result of its oat oil fraction, and also enhances topical delivery to the epidermis due to its aqueous fraction and the stabilizing effect of the oat bran as bulking agent.
    Type: Grant
    Filed: March 26, 1999
    Date of Patent: February 8, 2000
    Assignee: Albros, L.P.
    Inventors: Brian M. Albert, R. Richard Riso
