Pregnancy rash is a small papular rash, maculopapular rash or papular eruption around the body, accompanied by intense itching, which is usually unbearable and affects sleep and life. In terms of treatment, topical medication is needed, because oral medication may affect the fetus, and topical medication is mainly chosen from traditional Chinese medicine, which is very effective and safe. You can apply the Chinese medicine compound Huang Pai Jie (Yellow Cyperus) to remove ringworm, or apply the skin care lotion and apply it to the affected area twice a day for 20 minutes. After the application, apply Longzhu ointment or Qingpeng ointment to apply foam to play a role in clearing heat and detoxification; you can also apply boric acid zinc oxide ointment and black bean distillation oil to strengthen anti-allergy treatment.
