The herpes simplex virus is very difficult to eradicate. This is because once the human body is infected with the herpes simplex virus, this virus may remain in the human body. When the body’s immune function decreases or when the body is overly tired, as well as staying up late, drinking alcohol, or eating spicy and stimulating foods, the herpes virus may be triggered to become active and cause a state of illness. Therefore, when treating herpes, specific medication should be used according to the patient’s state of illness. If a patient has a relapse, he or she should be treated with antiviral medication and topical application of penciclovir cream or acyclovir cream. If there are ulcers and erosions, you can also apply topical rehabilitative new liquid to promote wound healing. But this herpes virus is generally difficult to remove fundamentally in the body.
