Salvia miltiorrhiza is one of the 40 most commonly used traditional Chinese medicinal materials in clinics.It is effective in activating blood circulation,removing blood stasis,relieving pain through the meridian,clearing the heart and removing irritations,and cooling blood and eliminating blemishes.Each main production area has developed a unique production method and processing technology,in accordance with local conditions.The processed products included in Chinese Pharmacopoeia are purified and wine-fried S.miltiorrhiza.In addition,the Chinese province's standards include the vinegar-fried and wine-fried types.S.miltiorrhiza is produced in more areas and is more extensively processed,with large variations in specifications.The challenge in establishing a uniform quality standard affects the clinical application of decoction pieces.This review has explored the books of the past dynasties,summarized the relevant literature published in the past three decades,discussed the processing methods of S.miltiorrhiza,and provided a basis for further research on the processing method of the original sample.In particular,we integrate fresh cut processing as the starting point for in-depth research,discuss the processing technology specifications,and formulate quality product standards.
