Astragalus extract is a concentrated form of the Astragalus membranaceus root, standardized to active compounds like polysaccharides or astragalosides. People take it to support immune function, especially during seasonal changes or stressful periods, and to help maintain vitality and energy.
People typically take astragalus extract in capsule or liquid form, with meals to aid absorption. Short-term use supports immune function, while longer use acts as a general tonic. Dosage depends on the extract's concentration.
Astragalus may interact with immunosuppressant drugs. If you have an autoimmune condition, avoid it unless a doctor supervises. It can also affect blood pressure and blood sugar, so consult a healthcare provider if you take medications for these. Do not use during pregnancy or breastfeeding.
