Anemarrhena rhizome is the dried tuber of Anemarrhena asphodeloides Bge. It is a rich source of various bioactive compounds such as flavonoids, saponins, alkaloids, tannins, choline, vitamins, and polysaccharides that support the optimal functioning of different organs including kidney, lungs, and stomach. Studies have reported that Anemarrhena rhizome improves symptoms of diabetes, cough, hot flushes, constipation, fever, and infectious diseases. Anemarrhena rhizome helps in clearing out heat from the body specifically from the stomach and lungs. It can also help control profuse sweating, irritability, high fever, and thirst during infectious conditions. Moreover, act as an expectorant, it can help to clear out phlegm produced in the lungs and relieve coughs. Medical studies have also reported that it inhibits the proinflammatory mediators, including interleukin and tissue necrosis alpha, and shows potent anti-inflammatory activity. Thus, it blocks not only the progression of inflammatory cascades resulting in inflammatory bowel disease and neurodegenerative disease, but also strengthens the immune response against unfavorable conditions.
Different studies have suggested that the Anemarrhena rhizome can be used to relieve fever, ease urination, decrease the level of cortical hormones, improve digestion via bile secretion, protect cells against toxins, and free radicals. It can also improve the symptoms of diabetes via decreasing insulin resistance and regulating the metabolism of glucose and lipids. It can also be used in combination with other herbs like licorice root, astragalus root, or Chinese yam for better control of diabetes.
Studies reported that Anemarrhena the rhizome contains potent steroid saponins that show anticancer activity and can be used to effectively manage different cancerous conditions such as breast and hepatic cancer etc. The mechanisms attributed to anticancer effects are inhibition of metastasis, apoptosis, and cancerous cell cycle arrest. Also, the presence of sarsasapogenin showed significantly antidepressant activity in animals via increasing the level of noradrenaline and serotonin.
Anemarrhena is an herb that can strongly drain heat from yin deficiency. It is categorized as a bitter, sweet and cold herb that clears heat and drains fire.
