Astragalus - Astragali, Huang QiAstragalus Supports healthy immune function; supports upper respiratory health; promotes energy; boosts stamina and vitality; digestive support; supports healthy liver and spleen function.
Historically, astragalus has been used in traditional Chinese medicine, usually in combination with other herbs, to support and enhance the immune system. It is still widely used in China for chronic hepatitis and as an adjunctive therapy in cancer. It is also used to prevent and treat common colds and upper respiratory infections. Astragalus has also been used for heart disease.
Astragalus is renowned in the East and West for its ability to stimulate the immune system and speed healing. Chinese doctors also recommend astragalus to treat weakness and excessive sweating.
Modern research shows that simple preparations of astragalus as a whole herb stimulate the immune system in several ways. It increases the number of stem cells in bone marrow, and encourages their maturity into active white blood cells. It appears to help signal the white blood cells known as neutrophils to migrate to places they are needed to fight infection. Astragalus stimulates the "germ-eating" white blood cells known as macrophages, activates T-cells and natural killer (NIK) cells, and increases the production of immune globulins. Usually taken with a variety of other herbs, astragalus as a whole herb eases chronic respiratory infections, aids in recovery from both cancer and the side effects of cancer therapy, and enhances health in HIV.
Cautions for AstragalusAstragalus may interact with medications that suppress the immune system, such as the drug cyclophosphamide taken by cancer patients and similar drugs taken by organ transplant recipients. It may also affect blood sugar levels and blood pressure.
