Abstract
The natural poison skin treatment method of the present invention includes applying to skin a composition including an effective amount of natural poison skin treatment medication selected from the group consisting of benzoyl peroxide and salicylic acid, an effective amount of a vasoconstrictor and an inert carrier. The natural poison skin treatment medication is therapeutic to natural poison skin conditions by acting as an antibacterial agent. The vasoconstrictor removes the redness normally associated with natural poison skin conditions as well as additional redness which may be caused by the benzoyl peroxide itself. The carrier is simply an inert flowing carrier to permit the application of the active ingredients to the skin. In preferred embodiments about 1 to 15% of the natural poison skin treatment medication based on the total weight of the composition is included. The preferred natural poison skin treatment medication is benzoyl peroxide and the preferred vasoconstrictor is tetrahydrozoline hydrochloride or a combination of tetrahydrozoline hydrochloride and zinc sulfate.
