Robert’s formula usually consists of cabbage leaf, geranium, marshmallow, slippery elm, echinacea and goldenseal. It sometimes contains bismuth, which kills H. Pylori, usually found in upper GI ulceration, as well as other microorganisms. Although never fully studied in placebo-controlled trials, Robert’s Formula has long been favored by naturopaths treating suspected inflammation in the GI tract. A typical dose is at least one capsule tid between meals.
Robert’s formula is becoming harder to find unless one goes to a liquid formula. Gaia Herbs has a preparation labeled Roberts Formula in a 4 oz size from their Supreme Compounds series. This is available through various outlets.
