Astragalus (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. It is sweet, and nourishing and often included in recipes for soups which are used for convalescence and general strengthening of the system. In Traditional Chinese Medicine it is said to tonify the "spleen" and hence is used for fatigue linked to decreased appetite. It is part of the Milk Vetch or Fabaceae family. It 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.
There is a great deal of research interest in Astragalus. The triterpenoid sapponins known as astragalosides support the integrity of mucous membranes and epithelial cells in the respiratory tract through an antioxidant mechanism. The polysaccharides are of particular interest for their immune supporting properties. It also supports deep immune function by promoting normal levels of specific immune cells and aids in their function. It appears especially effective when immune function is stressed by environmental or endogenous challenges.
