ABSTRACT
Shengmai San (SMS), also known as Shengmai Yin, is a traditional Chinese medicinal formula that is usually administered as a decoction. Over the past decades, a number of modern dosage forms have evolved from the modification of the original formula including the Codonopsis- and Ginseng-formula (Chen 1998; Hu et al. 1998). Although the official dosage form of SMS described in the Year 2000 edition of the Chinese Pharmacopoeia (CP) is an oral tonic, official standards of other dosage forms, such as capsule, syrup, granule, tea bag, tablet, and injection have also been established by the Ministry of Health, China.
