What Is It?

Astragalus membranaceus is one of the cornerstone herbal remedies in Traditional Chinese Medicine. It's long been used on its own and as part of herbal blends as a natural remedy for various disorders of the "qi." These conditions include fatigue, lack of appetite, diarrhea, and various ailments of the spleen.

Astragalus is considered an adaptogenic herb that helps protect the body against various stresses, including mental, emotional, and physical stress. Studies on Astragalus membranaceus have focused on its potential anti-inflammatory, cardioprotective, and longevity effects.

What Does It Do?

Astragalus membranaceus owes its effectiveness to the combination of the active ingredients contained within it. The main component that is most widely isolated and extracted is astragaloside IV (a steroidal sapogenin), which is patented and sold under the name TA-65. Typically, this proprietary extract is used as a longevity agent.

However, astragaloside IV has a relatively low bioavailability, meaning it isn't utilized by the body all that well post-ingestion. While this doesn't translate into elevated concentrations of the compound in the body, lower concentrations of astragaloside IV have demonstrated cardioprotective effects in clinical trials. The high flavonoid content of Astragalus membranaceus may also contribute to its cardioprotective effects.

Astragalus also demonstrates the capability the ability, via adipocytes (fat cells), to improve glucose metabolism and diabetic symptoms through a variety of mechanisms. Not much research exists on its effects regarding body fat, but it may possess a beneficial effect in treating obesity via increasing fat cell differentiation.

Lastly, and most important for the fitness enthusiast, Astragalus can enhance exercise endurance and performance. Studies using the herb found that supplementation reduced exercise-induced accumulation of the byproducts blood lactate and ammonia. This resulted in less fatigue and translates into improved exercise performance.
