Astragalus is available throughout the world. The most common species are grown in China, Japan, and Korea.
Astragalus is used to treat bronchitis, chronic obstructive pulmonary disease, colds, flu, gastrointestinal conditions, weakness, fatigue, chronic hepatitis, ulcers, hypertension, and (by injection) viral myocarditis (Chang et al, 1987). This herb is used in contemporary Chinese medicine and other models to improve immune system health. Astragalus is thought to be an aphrodisiac and may improve sperm motility.
