Ethnopharmacological relevance Pinellia ternata (Thunb.) Breit. is a well-known perennial herb that is used in traditional medicine in China, Japan and Korea. It's drawing worldwide interests in medicinal applications owing such as anti-diarrhea, lipid-lowering, anti-tumor, anti-cough, expectorant, anti-gastric ulcer, etc. Aim of the study This review aims to provide useful information on the botany, traditional uses, phytochemistry, pharmacology, toxicity and quality control of Pinellia ternata to help increase its efficiency. In addition, this review will discuss the future research trends and development prospects of this plant. Materials and methods Data was obtained through a systematic search of published literature and online databases such as Google Scholar, Web of Science, PubMed, Science Direct, and Sci-Finder. The botanical names were confirmed using the World Flora Online and chemical structures were drawn using the ChemBio Draw Ultra Version 19.0 Software. Results Pinellia ternata is distributed in regions of China and other areas. Pinellia ternata and its compound preparations can be used for cough, vomiting, gastric ulcer and other diseases. Approximately 212 chemical constituents have been isolated from Pinellia ternata , including alkaloids, volatile oils, amino acids, organic acids, flavonoids, cerebrosides, phenylpropanoids and other compounds. Considerable pharmacological experiments in vitro and in vivo have demonstrated that Pinellia ternata possessed antitumor effect, antitussive effects, antiasthmatic effects, increasing resistance to gastric ulcer, and antidiarrheal effect. However, these extracts can also lead to various toxicities such as irritant toxicity, cardiotoxicity, hepatotoxicity and embryonic toxicity. Considerable experiments have demonstrated that different processing methods and suitable compatibility with other herbs can effectively reduce the toxicities and increase the efficiency of Pinellia ternata . Conclusions Pinellia ternata is an ancient herbal medicine with a broad spectrum of pharmacological activities that has been used for thousands of years in China. Future studies should perform an in-depth analyses of the pharmacokinetics and mechanisms of toxicity of Pinellia ternata . Quality standards should be developed to correspond to the various application methods to ensure the efficacy of drugs in actual treatment.
