Overview of pharmaceutical technology of Lei Yun Liushen Pill.

Suzhou is located in the humid zone, with mild climate and abundant rainfall. It has the regional characteristics of low-humidity land, is prone to plague and epidemic, and has a high incidence of febrile diseases. Therefore, the influential Wumen Medical College has gradually formed. Traditional Chinese medicine in Beijing Tongrentang is mostly used as court medicine in the form of pills, while that in Suzhou Leiyun is in the form of small pills, which are used in small quantities and cheap, and are specially used for preventing and treating diseases for ordinary people. Liushen pill is one of the representative drugs.

Liushen Pill has enjoyed a high reputation since it came out in the early years of Tongzhi in Qing Dynasty, and its unique pill-making technology is unique to Lei, including the treatment of the original medicinal materials, which has its own uniqueness. Liushen Pill is finished by hand from material selection, pill spreading to final molding. Pan-pill is a traditional process of traditional Chinese medicine, but it is impossible for the general Chinese medicine industry to pan-produce pills as small as mustard seed as Liushen Pill. Therefore, the country regards the formula and technology of Liushen Pill as the key point of confidentiality, and it is strictly forbidden to visit and introduce it. Successive generations come down in one continuous line, which better protects its original craft tradition.
