Astragalus (Astragalus membranaceus)

About

Ashwagandha (Withania somnifera), sometimes called “Indian ginseng,” is a sturdy shrub growing to about 5 ft (1.5 m) with oval leaves, greenish or yellow flowers, and small, round fruits. NCCIH says some preparations may help insomnia and stress, but there isn't enough evidence to know whether it helps most other conditions.

Astragalus (Astragalus membranaceus), known in China as huang qi, is a perennial reaching about 16 in (40 cm), with hairy stems and compound leaves composed of multiple leaflet pairs. Its root has been used for centuries in traditional Chinese medicine, often with other herbs, and NCCIH says it is promoted to improve the response of the immune system. NCCIH says there is not enough reliable evidence to know whether astragalus helps any health condition.
