The blistering phenomenon after being stabbed by plants is considered to be due to contact dermatitis, which is mainly an inflammatory skin disease caused by skin contact with external substances, and can be relieved by removing the causative factors, applying topical medications, and taking medications orally. 1. Removal of triggers: patients are mainly allergic to plant thorns, so avoid re-exposure. At the same time, avoid hot water or excessive scratching, so as not to cause localized erosion and oozing phenomenon. 2. Topical medication: patients in the subacute phase without oozing, can choose glucocorticoid medication, such as hydrocortisone, betamethasone ointment and so on.
