A review of the pharmacology, application, ethnopharmacology, phytochemistry, quality control, processing, toxicology, and pharmacokinetics of Paridis Rhizoma

Paridis Rhizoma (PR) is also known as the flower with seven leaves and one branch, PR with golden thread, etc. It tastes bitter, numb, and slightly cold and has little poison. It is often used for the treatment of external skin infection, sore throat, snake bite, fall pain, frightening convulsion, and other diseases. PR has analgesic, sedative, anti-inflammatory, hemostatic, antitumor, antibacterial, antiviral, and renal and liver protective effects; inhibition of angiogenesis; immune regulation; and antioxidant and cardiovascular effects, and antifertility and anti-early pregnancy sperm killing effects. Steroidal saponins, β-ecdysone, polysaccharides, microelements, flavonoid glycosides, and amino acids were isolated from PR. In this paper, its pharmacology, application, ethnopharmacology, phytochemistry, quality control, toxicology, and pharmacokinetics were reviewed. This information suggests that we should focus on the development of new drugs related to PR, including specific ingredients, so as to make PR play a greater therapeutic potential. At the same time, attention should be paid to the rational use of PR resources to avoid excessive using, resulting in resource shortage. Therefore, we can carry out the research on the substitutes of PR, a large-scale planting of (Paridis Rhizoma) PR, and develop the same genus of PR and other resources. So far, great progress has been made in pharmacology and phytochemistry, especially in antitumor research, and many traditional uses have been confirmed and clarified by modern pharmacological research. However, there are few studies on the mechanism of its pharmacological action and few studies on processing. To develop new drugs in the future, more studies and experiments are still needed to prove the effect of PR and explore more new effects.
