皮炎平 is a medicine brand, which is used to treat skin diseases.

Hello, first of all this is a sentence of the typo, it should be“我生病了，悄悄地用完家中的皮炎平来擦，但是都没有任何效果，最后只好告诉妈妈我生病了” "I'm sick to rub quietly run out of the home in the Pi Yan Ping, but have no effect, and finally had to tell my mother I was sick." Pi Yan Ping drug is a treatment for the skin disease, is the name of the medicine, specializing in the treatment of dermatitis symptoms.Oh .... not quite understand?It does not matter, slowly Oh.

For the title, you should say "What does 皮炎平 mean?"
