On March 8, 2015, Women’s Day, I saw a 20-year-old female patient with eczema, rash on both hands and feet, distal lower extremities, dark red patches, partial exudation, intense itching. 5-6 years, Western medicine used various methods, also took a year of hormones, recurrent episodes, this time to our hospital acupuncture treatment, the effect is not obvious, and came to the dermatology clinic, explicitly requested internal Chinese medicine, refused antihistamines and He came to our hospital for acupuncture treatment and had obvious results. I had to prescribe Chinese medicine for 7 days based on tongue, pulse and skin lesions. When she came back to the clinic in the second week, the itching was reduced and the rash improved, so the original prescription was slightly modified and she continued to use the medicine for a while. I asked her if her diet was okay, and then I said how often do you take a bath, and she said once a day. I asked her to change her habit, but she said she couldn’t, but she was willing to take the medication and was very prompt in her follow-ups. After a period of treatment, especially with topical moisturizing emollients, the rash improved significantly after reducing bathing. I would like to remind some patients with skin diseases, such as eczema, pruritus and atopic dermatitis, that excessive bathing is not suitable, especially in winter when topical skin care products can be used to increase skin humidity, which is beneficial to the healing of skin lesions.
