Description:
Astragalus propinquus (syn. Astragalus membranaceus) also known as huáng qí (yellow leader) or bi qí, huáng hua huáng qí, is a flowering plant in the family Fabaceae. It is one of the fundamental herbs used in traditional Chinese medicine. It is a perennial plant and it is not listed as being threatened.
Astragalus (Astragalus membranaceus) has been used in traditional Chinese medicine for thousands of years to promote the discharge of urine, lower blood pressure, and increase endurance. Clinically, it is used primarily for general digestive disorders such as diarrhea, gas, and bloating, as well as chronic  phlegm production. This herb is also used for its immune enhancing properties, especially for the prevention and treatment of the common cold and chronic hepatitis. 
In the United States, astragalus has been investigated as a possible treatment for patients whose immune systems have been compromised by chemotherapy or radiation. Astragalus supplements have been shown to speed recovery and extend life expectancy in these patients. Research regarding the use of astragalus in people with AIDS has produced intriguing but inconclusive results. 
Recent research in China indicates that astragalus may offer antioxidant benefits in people with severe forms of heart disease, relieving symptoms and improving heart function. Because astragalus has many potential applications and few, if any, side effects, it holds promise as an alternative treatment option.
