Can Astragalus (Huang Qi) cause constipation?

When consumed properly, Astragalus (Huang Qi) generally does not cause constipation. It is typically prepared as an infusion—steeped in hot water and consumed as a tea. However, individuals with excessive Yang energy may experience constipation after drinking Astragalus tea, as its primary actions are to tonify Qi and elevate Yang. Astragalus tea promotes Yang generation; however, prolonged or excessive consumption may reduce intestinal moisture, potentially leading to constipation. In cases of Qi deficiency, appropriate use of Astragalus under medical supervision can help improve constitutional weakness. Individual responses to Astragalus vary depending on one’s constitution.
