Astragalus, usually referring to Astragalus membranaceus, is a perennial root herb in the Fabaceae family. Native to northern and eastern China, Mongolia, and Korea, it produces upright stems, small pinnate leaves, and pale yellow flowers. The dried root is the part most often used in traditional herbal practice and is commonly sliced for decoctions, soups, and tonic preparations.
In traditional East Asian herbal systems, astragalus is regarded as a strengthening root used to build daily vitality and support resilience over time. It is often simmered for long periods with other herbs or foods rather than taken as a quick infusion, which reflects its long-standing role as a slow, nourishing herbal tonic.
A mature astragalus root is usually harvested after several years of growth, and older roots are often preferred for herbal use because they are denser, sweeter, and more developed.
