Lorenzo's oil is a 4:1 mixture of glycerol trioleate an glycerol trierucate (the triglyceride forms of oleic and erucic acid) used in the preventive treatment of adrenoleukodystrophy (ALD). The oil was formulated by Augusto and Michaela Odone after their son Lorenzo was diagnosed with the disease in 1984, at the age of five. Augusto received U.S. Patent No. 5,331,009 for the oil. The royalties he now receives are paid to the Myelin Project which he and Michaela founded to further research treatments for ALD and similar disorders. The Odones and their invention obtained widespread publicity in 1992 because of the film Lorenzo's Oil.
