title: A double-blind study of sublingual provocative food testing: a study of its efficacy.
abstract: Fifteen patients with chronic allergic conditions were tested in a double-blind manner, using sublingual food drops containing egg, corn, milk, yeast or placebo. Edema and swelling of the nasal mucosa were observed as frequently when a placebo was given as when sublingual food drops were given. This method of testing does not differentiate between placebo and food drops.
