[The photodynamic effect in Herpes simplex: a review].

Photodynamic action is an extraordinarily potent physicochemical process which is dramatically lethal for herpesvirus and other organisms in vitro. Recent studies in animal models and man indicate that the process is effective against in vivo skin infections as well. Although a great deal is yet to be learned about the application of photodynamic action to clinical disease, current experience indicates that photodynamic action will find a permanent place in the physician's therapeutic armamentarium.
