Astragalus has been prescribed for centuries for general weakness, chronic illnesses, and to increase overall vitality. The genus Astragalus is a very large group of more than 2,000 species distributed worldwide, and is commonly known as milk-vetch root. In Traditional Chinese Medicine (TCM), Astragalus is classified as an herb that tonifies the qi and is indicated for symptoms of spleen qi deficiency such as diarrhea, fatigue, and lack of appetite. Astragalus tonifies the lung qi and is used in cases of frequent colds, spontaneous sweating, and shortness of breath. Astragalus is typically prescribed as a dried root, powdered, or in a decoction. Classically, Astragalus is prescribed in combination with other Chinese medicinal herbs, depending on the desired therapeutic effect and the specific TCM diagnosis. Astragalus root has been used to promote immune function and as a tonic to build stamina. Research shows Astragalus root stimulates the immune system in many ways. Astragalus increases the number of stem cells in bone marrow and lymph tissue and encourages their development into active immune cells. It appears to help trigger immune ceils from a "resting" state into heightened activity. One study showed Astragalus root helps promote and maintain respiratory health. It also enhances the body's production of immunoglobulin and stimulates macrophages. Astragalus can help activate T-cells and natural killer (NK) cells.
