Cold Sores
Although homeopathic substances listed in this article are generally not known to cause serious side effects, their effectiveness has not been demonstrated by scientific research. Consumers should check labels carefully, since a homeopathic product that is not diluted, or not diluted enough, may contain ingredients that cause allergic reactions, side effects, or interactions. It is always advisable to discuss any new treatment program with your healthcare practitioner.

Herpes is a common viral infection that causes painful cold sores around the mouth, as well as genital eruptions. A burning or itching sensation may precede the outbreak by several days. Eruptions are most likely to come out in times of stress and tend to reappear in the same locations. Homeopathic treatment can speed up the episodes of cold sores and limit their extension.
