Immune Terrain

Astragalus: Benefits, Dosage & What the Science Says

Astragalus membranaceus (Huang Qi) is one of the most important herbs in the Chinese pharmacopoeia, used for over 2,000 years as a foundational Qi tonic and immune modulator. Its polysaccharide and saponin fractions have been extensively studied for NK cell activation, T-cell proliferation, and interferon induction -- properties that make it central to Lyme-literate naturopathic immune terrain protocols.

What Is Astragalus?

The premier TCM immune tonic -- deep immune modulation and adaptogenic support

Evidence-Based Benefits

  • Deep immune modulation and NK cell activation
  • Qi tonification and fatigue resistance
  • Adaptogenic support for chronic immune load

Recommended Dosage

500--1500 mg standardized root extract daily, or 4--7 g dried root in decoction. Often used long-term (months to years) as a foundational immune tonic. Used in LymeCore and Lyme-literate protocols as a daily terrain support herb.

Generally very well tolerated; may potentiate immunosuppressive drugs -- consult before use if on cyclosporine or similar; some sources caution against use in active high-fever conditions (TCM: do not use when pathogen is in the exterior stage).
