The medicine is prepared, not only can improve the efficacy and reduce the toxic and side effects of the medicine, but also is convenient to store, is a necessary process of clinical medication of traditional Chinese medicine, is prepared traditional Chinese medicine decoction pieces as the material basis of traditional Chinese medicine treatment, and is not raw medicinal materials; the traditional Chinese medicine processing has the functions of enhancing efficacy and reducing toxicity, but different processing methods and processing techniques have great influence on the content of the active ingredients of the pummelo peel and even directly influence the clinical curative effect, so that the selection of a proper processing technique is very important for the curative effect of the pummelo peel in the processing process of medicinal materials.
Pummelo peel is originally found in Guangdong Tong Zhi (Guangdong Tong Zhi) in Kangxi 14 years, and originally belongs to the item of pummelo peel, and is separated out separately from pummelo peel in the Shenlong 30 years Zhao Zhimin (materia Medica gang mu Shi Yi). According to the record of the 2015 edition of pharmacopoeia of the people's republic of China, pummelo peel is derived from immature or nearly mature dry outer peel of pummelo peel of Rutaceae. The former is commonly called "Mao Ju hong", the latter is commonly called "Guang Qizhi" and "Guang Wu Zhi", which are warm in nature, pungent and bitter in taste. Has effects in regulating qi, relieving epigastric distention, eliminating dampness, and eliminating phlegm, and can be used for relieving cough, eliminating phlegm, protecting health of cardiovascular and cerebrovascular systems, caring skin, and removing toxic substance. Pummelo peel is the most important traditional Chinese medicine in the phlegm theory, and is called as Nanshen.
Pummelo peel is used as a traditional medicinal material, the history is long, the pummelo peel is usually processed in a moistening mode during processing, however, because the quality of immature pummelo peel fruits is hard and spherical, the moistening time is too long when the pummelo peel is processed by adopting a traditional moistening method, the interior is difficult to moisten, the content of effective components in the pummelo peel cannot be maximized, the content of the effective components of the pummelo peel in batches is unstable, and the processed pummelo peel is poor in taste.
