When herpes zoster is broken, it should be treated symptomatically according to the damage degree of local skin lesions. If it is only the rupture of the herpes blister wall that forms a certain erosion phenomenon, zinc oxide ointment can be applied externally to prevent the development of exudation reaction. If bacterial infection is secondary to skin damage, certain antibiotics should be used to prevent the spread of bacterial infection. For example, roxithromycin can be taken orally, and at the same time, it should be combined with waifusidic acid cream. It can also be treated with cold compress after the decoction of purslane according to the erosion degree caused by the damage.
