Herbal Textual Research on Local Varieties of Codonopsis Radix / 中国实验方剂学杂志

ABSTRACT

Codonopsis Radix， one of the bulk commodities， has been commonly used for tonification in clinical practice. Apart from the medicinal purpose， it can also be utilized as food. Among the multiple local varieties， the ones called "Luduiduoji" in Tibetan medicine cannot be neglected， which have frequently been adopted for diminishing inflammation and swelling， invigorating spleen and stomach， and tonifying Qi， etc. Considering its complex origins and frequent substitution by or confusion with other medicinal materials， this paper reviewed the Si Bu Yi Dian， Jingzhu Bencao， ministerial and local standards， modern literature on Tibetan medicine， and the results of field investigation in major Tibetan medicine hospitals and medicinal material markets of Sichuan， Qinghai and Tibet to figure out the name， original plants， medicinal parts， effects， and local varieties of Codonopsis Radix in Tibetan medicine. The results showed that the names of local varieties were diverse， many of which were transliterated into Tibetan， with "Luduiduoji" being most well-known. It was derived from 14 species in genus Codonopsis and one in Adenophora of family Campanulaceae， with Codonopsis foetens subsp. nervosa， C. thalictrifolia var. mollis， C. canescens， C. alpina， and C. pilosula being the main species. According to literature records， the roots， aerial parts， and whole plants could all be employed as medicine， but there were certain differences in their clinical applications. At present， in order to protect the medicinal resources， Tibetan medical workers mostly collect the aerial parts， which are applicable to patients with yellow water， rheumatism， Gamba disease， and leprosy. This literature review of local varieties for Codonopsis Radix and textual research on their original plants are of great significance for elevating the standard， accelerating the pharmacodynamic research， expanding the sources and promoting the rational use of Codonopsis Radix.
