Direct current successful against herpes

U.S. Patent 5,133,352 Method for Treating Herpes Simplex states "By the application of an electrical field and current to the area of the manifestation of the disease on the body there is activated a reaction at the cell level to combat the virus and disrupt its attack on the healthy cell structure. The present method comprises a direct application of a low voltage direct current, low amperage stimulation to the skin about the infected location for a few seconds every hour for a length of time sufficient to prevent formation and/or heal the resultant lesion."
"The most successful test group were those who treated themselves prior to lesion onset, group #3. The average duration of lesion existence for this group was only 1/4 day. It was also discovered that the sooner treatment starts after symptoms, the better the results. To prevent lesion formation it's necessary to start treatment within the first 12 hours after onset of symptoms."
