Andrographis is effective for herpes zoster, but because it is toxic, it is usually used topically to treat herpes zoster. In addition, herpes zoster that develops on the head and face, especially in the eyes and ears, must be taken seriously. Herpes zoster in the eye has an effect on vision and may even remove the eye if it causes severe infection. Herpes zoster that occurs in the ear may affect the eardrum, causing tinnitus and deafness. Herpes zoster that occurs on the face is more likely to induce facial paralysis, so it is important to pay attention to it and seek early medical attention. Please consult your doctor for specific medication and treatment instructions.
