Astragalus is a large genus of about 2,000 species of herbs and small shrubs, belonging to the legume family Fabaceae, subfamily Faboideae.黄芪属大类，约有XNUMX种草药和小灌木，属于豆科Fabaceae，Faboideae亚科。 The genus is native to temperate regions of the Northern Hemisphere.该属原产于北半球的温带地区。 Common names include milk-vetch (most species), locoweed (in western US, some species) and goat's-thorn (A. gummifer, A. tragacanthus).常见名称包括milk子（多数种），猪杂草（在美国西部，一些种）和山羊刺（A. gummifer，A。tragacanthus）。 Some pale-flowered vetches are similar in appearance, but vetches are more vine-like.一些淡花水的外观相似，但水more更像藤蔓。
Astragalus membranaceus is now being purified by supplement companies for the particular natural telomerase activating extracts.现在，补品公司正在纯化黄芪，以用于特定的天然端粒酶活化提取物。 Despite lack of evidence and testing, these extracts have started to be marketed as telomere enhancing, and life prolonging extracts.尽管缺乏证据和测试，这些提取物已经开始以增强端粒和延长寿命的提取物的形式销售。 As of January 2009 only three companies offer telomerase activator supplement products from Astragalus: TA Sciences, Terraternal, and RevGenetics provide Astragaloside IV or another extract derived from Astragalus for this purpose.截至XNUMX年XNUMX月，只有三家公司提供来自黄芪的端粒酶激活剂补充产品：TA Sciences，Terraternal和RevGenetics为此目的提供了黄芪甲苷IV或另一种从黄芪中提取的提取物。 However no independent tests have confirmed that these supplements actually activate telomerase in a human.然而，没有独立的测试证实这些补充剂实际上能激活人类的端粒酶。
