Astragalus is a large genus of plant consisting of approximately 2,000 species of herbs and small shrubs. This genus is native to the temperate regions of the Northern Hemisphere. Astragalus contains numerous compounds, including flavonoids, triterpene glycosides (in particular, astragalosides I – VII), amino acids and trace minerals, all of which contribute to its many benefits. The specific species used by traditional Chinese medicine is Astragalus membranaceus but it is commonly known as astragalus.
Traditional Chinese medicine has used astragalus as a remedy for weakness, edema, respiratory infections, diabetes, night sweats, diarrhea, heart disease and high blood pressure. Research in China also indicates that astragalus may provide antioxidant benefits to those who suffer severe forms of heart diseases by relieving symptoms and improving heart function. Other studies show that astragalus may help boost the immune system and improve survival in cancer patients.
On the other hand, astragalus has only been the subject of studies recently in the United States. Certain medical journals suggest that this powerful herb may stimulate the immune system and the body’s ability to combat various diseases. Investigations by the National Cancer Institute are on-going as they try to explore other possible medical benefits of astragalus, including the treatment of AIDS. It is believed by many that this herb holds promise in treatment options as it has many potential applications and few, if any, known side-effects.
There is no set recommended daily intake value for astragalus because much is still being studied. Capsules, containing 150 – 500 mg of astragalus powder and taken 8 – 9 times per day, are often sold as herbal supplements. Fluid extracts are also available in the market. In traditional Chinese medicine, it is common to consume astragalus in combination with other herbs.
