Eczema in a forty-day-old baby usually appears as papules and papules, with some of the rashes fusing into patches, accompanied by a certain amount of itching, and if the itching is more intense, vesicles and oozing can also occur. Usually, oral medication is not given, but can be applied topically, but the specific treatment plan needs to be chosen according to the specific form of the rash. If there is a large area of vesicles and exudation, a cold moist compress of Chinese herbal medicine with decoction of fresh amaranth, honeysuckle, forsythia, scutellaria, and scutellaria should be applied to the affected area twice/day for 5 minutes, followed by anti-inflammatory ointment mupirocin or compound polymyxin B ointment. In case of large rash fusion, a weak glucocorticoid ointment, such as hydrocortisone ointment, can be applied twice/day. After the rash improves apply zinc oxide borate ointment as a replacement therapy to reduce the side effects of hormones.
