The Taiwan FDA has introduced new regulations limiting the use of aloe vera in food products to prevent safety concerns. The regulations mandate the use of Aloe Ferox leaves, with the skin completely peeled, and limit the presence of aloin, a potent laxative, to less than 10 ppm. Products containing aloin must carry caution labels, unless tested to contain less than 1 ppm. The regulations also warn that companies not complying with these regulations could face significant fines. Similar restrictions are under consideration in Europe and South Korea due to the potential toxicity and carcinogenicity of hydroxyanthracene derivatives present in aloe vera.
