Amygdalin ('Laetrile')..has been employed medically for many centuries. Ancient herbal pharmacopeias recommended the bitter almond for the treatment for a variety of illnesses.
Six patients with advanced cancer were treated with amygdalin at dosages similar to those employed by Laetrile practitioners....intravenously... (and) orally...No clinical or lab evidence of toxic reaction was seen (by us).
One patient had severe pre-treatment pain resulting from skeletal meta-stases...at 5 weeks after the onset of (laetrile and metabolic) therapy, she claimed complete relief.
