Astragalus
Adverse Effects
Adverse effects from astragalus are uncommon, but rash, itching, nasal symptoms, or stomach discomfort may occur. Astragalus might make the immune system more active, which can worsen the symptoms of autoimmune diseases such as rheumatoid arthritis and systemic lupus erythematosus. Astragalus should not be used during pregnancy or while breastfeeding. Animal studies suggest that astragalus can be toxic to the mother and fetus.
