What are the benefits and side effects of Astragalus?
Astragalus membranaceus (Huangqi) is generally known for its effects of reinforcing qi and strengthening the defensive system, promoting diuresis to reduce edema, enhancing qi and fluid production, expelling toxins and promoting pus discharge, and boosting immune function. Potential side effects may include inducing heat-related symptoms, exacerbating yin deficiency with internal heat, causing blood pressure fluctuations, impairing digestive function, and triggering allergic reactions. Before using Astragalus, one should clearly understand their body constitution—those with qi deficiency may use it moderately, while individuals with yin deficiency and excessive fire or internal damp-heat should avoid it.
