Astragalus is a qi tonic, which is essential for tonifying the spleen and qi, and is often used clinically to treat prolonged diarrhea and prolapse of the anus, and loose stools (thin, unformed feces) caused by a deficiency of the spleen and qi subsidence. Astragalus with Huang Jing can increase the effect of qi tonic. 2. Huang Jing’s function is to tonify qi, nourish yin, strengthen the spleen, moisten the lungs and benefit the kidneys.
