The Gerson Institute (homepage)

The Gerson Institute's own current website, fetched directly. It describes the Institute as a 501(c)(3) nonprofit founded in 1978 and as a global source for information, licensing, training, and patient support. It claims the therapy boosts the immune system to heal cancer and other diseases while separately declining to guarantee individual effectiveness, and it says the Institute itself is not a medical facility. Used as the primary source for the active enterprise's current marketed claim.
