Safrole is regarded by the U.S. government to be a weak carcinogen in rats.[4] It naturally occurs in a variety of spices such as cinnamon, nutmeg, black pepper and herbs such as basil. In that role safrole is believed, although not proven, to make a small but measurable contribution to the overall incidence of human cancer, equal to the hazards presented by orange juice and tomatoes.[5] In the United States, it was once widely used as a food additive in root beer, sassafras tea, and other common goods, but was banned by the Food and Drug Administration (FDA) after its carcinogenicity in rats was discovered. Today, safrole is also banned for use in soap and perfumes by the International Fragrance Association.
According to a 1977 study of the metabolites of safrole in both rats and humans, two carcinogenic metabolites of safrole found in the urine of rats, 1'-hydroxysafrole and 3'-hydroxyisosafrole, were not found in human urine. This brings to question the actual carcinogenicity of safrole in humans.[6]
