More than one-fourth of egg-allergic children lost their egg allergies altogether after receiving carefully metered and increasingly larger doses of egg-white powder over a 10-month period. Other research has shown that similar oral immunotherapy can be useful in treating children's allergies to milk and peanuts.

A three-day course of a drug derived from Thapsia garganica, a Mediterranean weed, reduced human prostate tumors grown in mice by more than 50 percent within 30 days. The same drug produced at least 50 percent regression in models of breast, kidney, and bladder cancers.
