What traditional systems uses this plant?
This plant, known as wilfordii root, has been utilized for centuries within Oriental medicine systems to treat various inflammatory and metabolic conditions. In traditional Chinese medicine, practitioners have historically prescribed it to clear heat and resolve toxicity in the body. It was frequently used to address skin ailments, swellings, and digestive irregularities. Some historical applications also focused on its ability to regulate blood flow and promote healing in internal organs. These long-standing practices laid the groundwork for modern scientific investigations into its bioactive compounds.
According to a study published by "Biological & pharmaceuctical bulletin", Cynanchum wilfordii is one of the most widely used medicinal plants in Oriental medicine for the treatment of various conditions. The study utilized an extract of Cynanchum wilfordii roots (CWE) and its isolated component, cynandione A (CA). In experiments, CWE up to 500 µg/mL and CA up to 80 µM did not exhibit cytotoxic activity. These substances significantly decreased LPS-induced nitric oxide production and iNOS expression in a concentration-dependent manner. Research indicates that CWE and CA may have effective anti-inflammatory activities via NF-κB inactivation in stimulated microglial cells.

According to a study published by "Nutrition research (New York, N.Y.)", Cynanchum wilfordii extract is used to attenuate liver fat accumulation and damage in mice fed with a high-fat and high-fructose diet. This extract was evaluated in a murine model of nonalcoholic fatty liver disease using doses of 50, 100, or 200 mg/kg with n=6/group. Supplementation of the extract at 100 and 200 mg/kg (P<.05) ameliorated impaired liver functions, such as increased blood levels of glutamic oxaloacetic transaminase and glutamic pyrviic transaminase. The treatment also suppressed signaling pathways associated with inflammatory responses, specifically COX-2, NF-κB, and p38 MAPK, when administered at 100 and 200 mg/kg. Ultimately, the study found that the extract reduced fat accumulation and damage in the liver induced by high-fat and high-fructose diets.
