Essiac
secondary literature · 2021
SUMMARY
MSKCC's current integrative-medicine monograph, stating plainly that "Essiac has not been shown to treat or prevent cancer," and noting that in laboratory studies rhubarb (an Essiac ingredient) suppressed part of the immune system, contradicting immune-boosting marketing claims. Lists the four core ingredients (burdock root, sheep sorrel, slippery elm, rhubarb). Fetched directly 2026-08-17.
NOTES
A current, major U.S. cancer center’s authoritative herb monograph, used as this case’s second present-day-critique source and for confirming the four-herb ingredient list independently of the promotional literature.
