A formulation, method and system for the topical, transdermal or transmucosal administration of a therapeutically effective active agent. Particularly, the invention provides a formulation, system and method for enhancing the permeation or penetration of active agents across the dermal or mucosal surfaces of a mammalian subject. The formulation includes a plant extract of the genus Curcuma of the family Zingiberaceae, a germacrone, or a natural or synthetic constituent thereof, which has been found to increase penetration of the active agent across the dermal or mucosal surface. If desired, a secondary permeation enhancer of a polyalcohol, a monoalkyl ether of diethylene glycol, a tetraglycol, or a mixture thereof can be used for certain active agents for optimal permeation enhancement. |
