Astragalus propinquus, Astragalus membranaceus


Astragalus propinquus (Huang Qi) has been a foundational herb in Traditional Chinese Medicine for hundreds of years. It is included in formulas to support Wei Qi (Chi), or the conceptual “shield” which serves as a primary defense mechanism against pernicious threats to the system. Sweet and nourishing, Astragalus is often included in recipes for soups, which are used for convalescence and general strengthening of the system. In Traditional Chinese Medicine, Astragalus is said to tonify the “spleen” and hence is used for fatigue linked to decreased appetite. Astragalus is part of the Milk Vetch or Fabaceae family. Astragalus herb is traditionally used in its dried powdered form or as a strong decoction, made from boiling the dried root in water for an extended period.
