T/CAQ 29021-2024 Quality Chinese medicinal herbs Poria cocos

Scope

Scope: This document specifies the requirements, testing methods, inspection rules, judgment rules, labeling, packaging, and storage for high-quality traditional Chinese medicinal materials, Poria (Fuling). This document applies to the evaluation of high-quality Poria (Fuling). Main technical content: Poria (Fuling) is a commonly used traditional Chinese medicinal material in China. It has the functions of promoting water excretion and dampness elimination, strengthening the spleen, and calming the heart. It is used in the treatment of edema, oliguria, phlegm-dampness-induced dizziness and palpitations, spleen deficiency with poor appetite, diarrhea and loose stools, and restless sleep. The *Pharmacopoeia of the People's Republic of China* (2020 Edition) stipulates the testing items of "appearance", "identification", "inspection", "extraction", and "content" for Poria (Fuling) materials, and also sets limits for 33 prohibited pesticides. However, the existing standards cannot meet the diverse needs of market transactions for Poria (Fuling) materials. It is necessary to establish quality grading standards to guide high-quality and high-priced products and form a virtuous cycle, jointly promoting the high-quality and healthy development of the Poria industry. To better assess the quality of Poria (Fuling), high-quality traditional Chinese medicinal materials Poria (Fuling) have emerged. The quality indicators of high-quality Poria (Fuling) exceed the requirements of the *Pharmacopoeia of the People's Republic of China*, and the limits for exogenous contaminants such as lead, cadmium, mercury, and arsenic are lower than those in the *Pharmacopoeia of the People's Republic of China*. Compared with the provisions in the *Pharmacopoeia of the People's Republic of China*, high-quality Poria (Fuling) adds limits for heavy metals and harmful elements such as lead, cadmium, mercury, and arsenic, and also stipulates the maximum residue limits for 226 pesticides.
