Gum guaicum, or guaiac resin,[2] is a substance produced from the tree species Guaiacum officinale. It is registered as food additive: as a preservative under the E number E241, and as an antioxidant under E314.[3]
Guaiac resin is also used medically for the stool guaiac test.
Chemically, it is mixture of approximately 70% alpha- and beta-guaiaconic acids, 10% guaiaretic acid, 15% guaiac beta-resin, and small quantities of other chemical compounds such as guaiac yellow and vanillin.[2]
