Guggul, the Commiphora mukul, is a small thorny tree that is native to the Middle East and the Indian plains. Generally leafless, the tree exudes a thick, sticky resin that has been used in Ayurvedic medicine for centuries. Guggul has written historical information about it going back to 1000 B.C.E. It was used at that time for “clearing the coating and obstruction of channels”. The gum exuded by the guggul tree is similar to myrrh, and has been used traditionally in the same ways as myrrh. The Guggul Gum offered by Mountain Rose Herbs is raw, and may need further processing for some applications.

Commiphora erythraea (Burseraceae) resin derives from the bark injury of the plant, a small tree native to the Arabian Peninsula. The resin is commonly known as Haggar gum and it is traditionally used to protect livestock from ticks and to treat diseases related to inflammation. The resin is constituted by a volatile and a non-volatile fraction, they used it as incense in temples. It is fairly widespread in Somalia and in adjacent parts of the Ogaden region in Ethiopia, and speaking of its export, Somalia is considered the major exporter of scented myrrh.
