Once chickenpox symptoms begin, there is no chickenpox cure -- except time. When symptoms occur, the goal of treatment for chickenpox is to relieve the symptoms while the body fights the chickenpox virus. In 5-10 days, the symptoms of chickenpox should be gone.
Some people may think of the chickenpox vaccine as a chickenpox cure. By definition, a cure is a method or course of treatment, such as a drug, used to restore health. Since the chickenpox vaccine prevents chickenpox from occurring in the first place, it is considered to be a form of chickenpox prevention rather than a chickenpox cure.
