If a patient has herpes on the lips after taking herbal medicine, it may be related to the nature of the herbal medicine or it may be a viral infection. It may be related to the fact that the herbal medicine taken is too warm, which may occur when using too large a dose of warm medicine or using it for a long period of time; However, the appearance of herpes is not necessarily caused by taking traditional Chinese medicine, so you should stop taking the medicine and go to the hospital for relevant examinations to clarify its cause. Generally herpes around the lip is mostly a viral infection, which is mainly treated by antiviral drugs, such as oral acyclovir. The above drugs should be taken under the guidance of a physician, and patients should not blindly take them on their own. If the herpes improves, should be under the guidance of the physician to determine whether to continue to take the previous Chinese medicine.
