The active substance affects the herpes virus (Herpes simplex) type 1 and 2 and the Varicella zoster virus.
The causative agent may be present in the body for a sufficiently long period and not be active. At the time of its activation (for example, when a flu, a cold or due to fatigue occurs), the virus begins to multiply. This provokes the formation of bubble rashes.
