Radix Astragalus (Huang Qi 黄芪)

Radix Astragalus  黄芪

Astragalus, Radix (Chinese: Huang qi; English: milk-vetch root) was called "the senior of all herbs" in the Essentials of the Materia Medica (1694AD). Tonifies the Spleen, Stomach, qi and blood and benefits the immune system (1,2). Research has shown it to lower blood pressure (3) and increase endurance. This herb is considered one of the world's greatest immune tonics and in fact is the principal substance listed in the materia medica for stabilizing and strengthening the protective Qi (immune system). Combines well with Ginseng, Glycyrrhizae, Angelica Sinensis, Cinnamomi, or Paeoniae.
Notes: When Astragalus and Ginseng are combined, they complement each other. Astragalus contributes a quick, ascending quality, which stregthens the exterior and Ginseng prolongs the action, supporting the deeper areas of the body, and also nourishing and protecting the yin. This combination provides the foundation for many formulas, including Bu Zhong Yi Qi Wan and Shi Quan Da Bu Wan. You can also combine Astragalus with Codonopsis for the same effects as Codonopsis is commonly used as a Ginseng substitute.
Use 9-30 grams.
