Astragalus

Figure 1. The Astragalus membranaceus plant.

Astragalus is the scientific genus name that spans over 3,000 species of herbs and small shrubs belonging to the legume family Fabaceae and the subfamily Faboideae. It is the largest genus of plants in terms of described species. The genus is native to temperate regions of Northern Hemisphere countries.

Astragalus or more specifically, its root, is used in traditional Chinese medicine to treat various disorders. It is considered an adaptogen. Extracts of Astragalus roots include diverse phytochemicals, such as saponins and isoflavone flavonoids, which are used to increase lactation among nursing mothers in traditional medicine. Astragalus is also often promoted for beneficiary effects on the human immune system, respiratory system, hay fever, asthma, kidney, liver, heart, and cardiovascular system. Topical use (application to the skin) of astragalus is promoted for improving blood flow and speeding wound healing. However, there is insufficient scientific evidence presently to support these applications.

Most astragalus supplements contain Astragalus membranaceus (synonymous Astragalus propinquus), a type of flowering plant, or otherwise known as huang qi (in Mandarin) or Mongolian Milkvetch. The herb is said to offer multiple health benefits for multiple conditions.

Consumption of Astragalus may induce possible side effects, including rashes, itching, nasal symptoms, or stomach discomfort.
