Historical evolution of Salviae Miltiorrhizae Radix et Rhizoma processing methods / 中国中药杂志

ABSTRACT

China has a long history of Salviae Miltiorrhizae Radix et Rhizoma processing with multiple methods available. The pre-sent study collated and summarized the Salviae Miltiorrhizae Radix et Rhizoma processing methods recorded in 23 related herbal medicine books, all editions of Chinese Pharmacopoeia, the 1988 edition of National Regulations for Processing of Chinese Medicine, and 20 current local processing specifications and standards. The results demonstrated various processing methods of Salviae Miltiorrhizae Radix et Rhizoma, such as removing residual part of stem, plantlet, or soil, smashing, filing, cutting, decocting, washing with wine, soaking in wine, and stir-frying with wine or blood from pig heart, while raw and wine-processed products are mainly used in modern times. Due to the lack of unified standards, the phenomena of multiple methods adopted in one place and different methods in different places have led to uneven quality of Salviae Miltiorrhizae Radix et Rhizoma pieces, even affecting the safety and effectiveness of its clinical medication. This study is expected to provide a reference for the development of Salviae Miltiorrhizae Radix et Rhizoma processing and its rational medication.
