Bellium (Hebrew bedolach) was an aromatic gum like myrrh that was exuded from a tree. It has been identified with the species Commiphora wightii, now called guggul, although bdellium was also used for the African species C. africana and at least one other Indian species, C. stocksiana. Bdellium was an adulterant of the more costly myrrh (Commiphora myrrha); guggul is still used as a binder in perfumes.
