    Benefits

    Astragalus The benefits of astragalus root have been known for a long time. For thousands of years, it has been used to treat viral infections in traditional Chinese medicine, including the common cold. It has been shown to increase white blood cells (WBCs) in individuals with leukopenia (a condition characterized by low WBCs) and, according to animal research, stimulate T-cell activity and other factors of the immune system. It appears especially useful in improving immunity function in patients undergoing chemotherapy or radiation.[1-3]

    A recent study at the UCLA AIDS Institute says it is possible astragalus root may be a powerful weapon against the HIV virus (without the harmful side effects of prescription drugs).

    Astragalus root is an adaptogen, meaning it increases the body's resistance to fatigue, anxiety, stress, and trauma. It is said to help treat gastrointestinal disorders, including stomach ulcers, gas, bloating, and diarrhea. Other possible benefits include treating heart disease, high blood pressure, kidney diseases, respiratory infections, and asthma.

    Locoweed

    There are many species of astragalus but the one used for medical purposes is astragalus membranaceus. Another species of astragalus (astragalus lentiginosus - also known as locoweed) grows in the western part of the United States and should not be used. This species contains neurotoxins and is harmful to herbivores, mostly cattle and horses. It got its name locoweed (loco meaning "crazy" in Spanish) because of the behavior from the animals that consumed it.
