Overview
Astragalus is the classic qi tonic for the body's surface. Where ginseng restores deep vitality, astragalus is traditionally used to firm the exterior, reduce spontaneous sweating, and support people who catch colds easily. In Korea it is a familiar ingredient in summer chicken soup (samgyetang).
