Astragalus

Herb

Astragalus botanical products marketed for immune, kidney, or longevity claims. Clinical findings are preparation-specific, and a recent telomere trial tested a multi-ingredient Astragalus-based supplement in only 40 participants rather than Astragalus alone.

Pharmacokinetic model

A route-level PK model for astragalus is being prepared from published data. Dosing references, studies, and documented interactions are below; the app catalog is updated as models are validated.
