Although astragalus has over 2,000 species, the one most used in medicine is Astragalus membranaceus. It usually grows as a small, bushy, perennial plant in dry, sunny areas.
The perennial grows to about 0.3 m by 0.3 m. The flowers are hermaphrodite (have both male and female organs) and are pollinated by bees, moths and butterflies. The plant cannot grow in the shade. It requires dry soil.
This herb is the root of perennial herbaceous plants Astragalus membranaceus (Fisch. ex Link.) Bunge., and Astragalus mongholicus Bunge., of the family leguminosae. Native to east Asia, the plant is grown on dry sandy soils in China, Mongolia.
The part of astragalus used in medicine is the root, which is long, thin, and woody with many small offshoots. Fresh roots are white, yellow, or cream-colored and they smell and taste somewhat like licorice. Astragalus roots are dried either whole or after being cut into slices, which may have been dipped into honey. In China, where astragalus is grown commercially from seed, plants must be 3 or 4 years old before their roots can be harvested. Because it is in high demand, astragalus may also be grown more quickly in bioreactors large tanks that use artificial conditions to grow plants or other organic material such as fungi or yeast.
In China, A. membranaceus is mainly produced in Inner Mongolia, Hebei, Shanxi, Gansu,Nign Xia,Heilongjiang, Jilin,north to the westernmost province of Xinjiang,west to the mountains of Sichun and other areas. Generally, only plants of more than 4 years old can be used.
It is found along forest margins, in shrub thickets, thin open woods, and grasslands near the edge of forests. The Chinese harvest its roots when plants are four to five years old. Before completely dry, the roots are sliced into thin diagonals or sliced lengthwise, producing a dried product that looks like a tongue depressor.
The root can be dug out in spring and autumn. The root is cleared of stem and leaves and of fibrous rootlets, cleaned, thoroughly moistened, cut into thick slices, dried and used unprepared or honey-processed.
Also called Membranous Milk Vetch Root and Chinese Astragalus Root.
