Selling dog skin plaster means

Speaking of selling dog skin plasters, it is somewhat derogatory, because dog skin doesn't sound like a very good thing. Dog skin plasters refer to people who cheat in Jianghu and sell them with some deceptive things as a panacea. So where did the saying of dog skin plaster come from? Let's find out.

Traditional dogskin plaster is made of more than a dozen Chinese herbal medicines such as Radix Aconiti, Radix Aconiti Kusnezoffii, Notopterygii Rhizoma, Radix Angelicae Pubescentis and Borneolum Syntheticum. The black ointment is made by crushing, frying, deslagging, filtering, taking ointment, melting and other processes. And spread on the supporting material to form a traditional dogskin plaster. No matter where there is pain, leg cold, knee arthritis, lumbar muscle strain and so on. Take a dogskin plaster, heat it slightly to soften it, and stick it on the sore spot or acupoint, and most of the medicine will be cured. The reason why "dog skin plaster" is now considered as a derogatory term is because people who used to run around the Jianghu often made fake dog skin plaster to cheat people. Over time, "dog skin plaster" has become a derogatory idiom.
