About Astragalus

Plant: Astragalus membranaceus (Huang Qi)

An immunostimulating herb that raises interferon-gamma and IL-2, and increases CD4 counts. Best suited to pre-exposure and early-stage Lyme.

Reference dosing

Tincture dose — 1:5	2.5–5ml, 3–4 times daily
Tincture dose — 1:3	1.5–3ml, 3–4 times daily
Capsule dose (mg)	1,000–4,000mg, 3–4 times daily (stated by Buhner)

Contraindicated in late-stage chronic Lyme — can aggravate symptoms by over-stimulating an already elevated Th1 immune response.

Capsule whole-herb extracts vary by manufacturer (a concentrated extract needs less than a plain powder). Treat these figures as a guide only and follow the product label.

These are figures from the sources used on this site. They are not a prescription. Follow the product label and your prescriber.

Safety and cautions

Contraindications: Contraindicated in late-stage chronic Lyme disease specifically — stimulates already-elevated Th1 immune pathways and can aggravate symptoms. Only appropriate for pre-exposure, early localized, or early disseminated stages.

Herbs can interact with prescription medicines and other supplements. Check with your prescriber or pharmacist first, and do not use herbs in pregnancy or while breastfeeding unless a doctor agrees.
