About Astragalus Extract
Astragalus Extract contains a wide array of constituents including flavonoids, sapponins, polysaccharides, free form amino acids, essential fatty acids and trace minerals. The triterpenoid sapponins known as astragalosides support the integrity of mucous membranes and epithelial cells in the respiratory tract through an antioxidant mechanism. The polysaccharides are of particular interest for their immune supporting properties. Astragalus is shown to effect non-specific defenses such as promoting macrophage and monocyte function as well as interferon activity. It also supports deep immune function by promoting natural killer cell and t-cell function. It appears especially effective when immune function is stressed by environmental or endogenous challenges.
Astragalus Extract is an herb that has been used for centuries as a natural way to support the body's immunity (defense) system.  Known since ancient times as the "superior tonic," Astragalus Root Extract is also used as a natural aid for healthy digestion and metabolism.  Many people also believe it helps boost their energy levels and overall stamina.
