Several uncontrolled clinical studies support the topical use of echinacea to enhance wound healing. A trial involving 4598 people investigated the effects of a preparation consisting of the juice of the aerial parts of E. purpurea on various wounds, burns, skin infections and inflammatory skin conditions (Kinkel et al 1984). Topical application of echinacea produced a 85% overall success rate, and the key constituent
responsible for enhancing wound healing appears to be echinacoside (Speroni et al 2002).
Commission E approves the external use of E. purpurea herb for poorly healing wounds and chronic ulcerations (Blumenthal et al 2000).
