Echinacea
Immune & Inflammation · Herbal immune modulator
Tier B-
Bottom line
Read Off Label grades Echinacea as B- (6.2/10) based on weak-moderate evidence, low-med benefit magnitude, and a low-risk safety profile.
Quality hugely variable — different species, different plant parts, different extraction solvents, and different alkamide/cichoric acid standardization all produce different clinical results.
Typical use: Species and preparation specific; 300-500 mg 2-3x/day dried herb or equivalent tincture — OTC.
What this is
Quality hugely variable — different species, different plant parts, different extraction solvents, and different alkamide/cichoric acid standardization all produce different clinical results. A. Vogel Echinaforce (E. purpurea fresh-pressed) has the most positive trial data. Start at first cold symptoms rather than chronic prophylaxis.
Mechanism
E. purpurea, E. angustifolia, E. pallida — alkamides, cichoric acid, polysaccharides; proposed TLR activation and macrophage/NK stimulation; aerial parts vs root differ
Dose & route
Species and preparation specific; 300-500 mg 2-3x/day dried herb or equivalent tincture

Common questions
- Does Echinacea work?
- Read Off Label rates the evidence for Echinacea as Weak-Moderate and the benefit magnitude as low-med, producing an overall grade of B- (6.2/10). Quality hugely variable — different species, different plant parts, different extraction solvents, and different alkamide/cichoric acid standardization all produce different clinical results.
- Is Echinacea safe?
- Echinacea has a low risk profile in published human data. Legal status: OTC. This is not medical advice — see the disclaimer.
