Astragalus
Astragalus (As-trá-ga-lus) is a large genus of about 3,000 species[1] of herbs and small shrubs, belonging to the legume family Fabaceae, subfamily Faboideae. The genus is native to temperate regions of the Northern Hemisphere. Common names include milk-vetch (most species), locoweed (in western US, some species; although most locoweeds are not genus Astragalus but in related genera)[2] and goat's-thorn (A. gummifer, A. tragacanthus). Some pale-flowered vetches are similar in appearance, but vetches are more vine-like.

Species
Astragalus species are used as food plants by the larvae of some Lepidoptera species including the following case-bearers of the genus Coleophora: C. astragalella (feeds exclusively on A. glycyphyllos), C. cartilaginella (feeds exclusively on Astragalus), C. colutella, C. euryaula (feeds exclusively on Astragalus), C. gallipennella (feeds exclusively on A. glycyphyllos), C. hippodromica (feeds exclusively on A. gombo), C. onobrychiella (feeds exclusively on Astragalus), C. polonicella (feeds exclusively on A. arenarius) and C. vicinella.
Traditional uses
The natural gum tragacanth is made from several species of Astragalus occurring in the Middle East, including A. adscendens, A. gummifer, A. brachycalyx,[3][4] and A. tragacanthus. Also Astragalus propinquus (also known as Astragalus membranaceus) has a history of use as a herbal medicine and is used in traditional Chinese medicine.[5]
Research
The biotechnology firms Geron Corporation and TA Therapeutics of Hong Kong have been working on deriving a telomerase activator from it. The chemical constituent cycloastragenol (also called TAT2) is being studied to help combat HIV, as well as infections associated with chronic diseases or aging.[6] However, the National Institutes of Health states: "The evidence for using astragalus for any health condition is limited. High-quality clinical trials (studies in people) are generally lacking. There is some preliminary evidence to suggest that astragalus, either alone or in combination with other herbs, may have potential benefits for the immune system, heart, and liver, and as an adjunctive therapy for cancer".[7]
In a study published in the 15 November 2008 Journal of Immunology, researchers shed light on the antiviral and antiaging benefits of Astragalus. In their paper, a team of researchers from the UCLA AIDS Institute described how their work with cycloastragenol reduces the aging process of immune cells, and enhances how these cells respond to viral infections. The compound works by boosting production of telomerase, an enzyme that allows for the replacement of short bits of DNA, known as telomeres, that play a key role in cell replication, cancer and human aging.[8]
Supplement use
Extracts of Astragalus membranaceus (syn. Astragalus propinquus) are marketed as life prolonging extracts in humans. A proprietary extract of the dried root of Astragalus membranaceus, called TA-65, 'was associated with a significant age-reversal effect in the immune system, in that it led to declines in the percentage of senescent cytotoxic T cells and natural killer cells after six to twelve months of use.'[9] In October 2010, Intertek/AAC Labs, an ISO 17025 internationally recognized lab, found the largest component of TA-65 to be Cycloastragenol.[10] Telomerase activation was feared to pose an increased risk of cancer because telomere shortening is a mechanism that limits cell proliferation. However, short telomeres result in chromosome instability, hence there is also a potential mechanism for telomere lengthening to protect against cancer (as distinct from mutation-induced activation).[11]
Side effects
Astragalus may interact with medications that suppress the immune system, such as cyclophosphamide.[7] It may also affect blood sugar levels and blood pressure.[7] Some Astragalus species can be toxic. For example, several species that grow in the United States contain the neurotoxin swainsonine.[7]
Toxicology
The family of Astragalus has been reviewed by Rios and Waterman, indicating that the toxicities vary from one species to another.[12]
Ornamental use
Several species, including A. alpinus (bluish-purple flowers), A. hypoglottis (purple flowers) and A. lotoides, are grown as ornamental plants in gardens.
