Guggul is the common name for the flowering mukul myrrh tree (Commiphora mukul). It is a small, thorny tree that is most commonly found in India, in the arid climates of states such as Rajasthan and Gujarat.1, 2 Guggul also refers to the resin formed from the sap of the guggul tree, which has been used in Ayurvedic medicine for over two thousand years.3 Guggul is known by the Sanskrit name "Guggulu," which means, "protects from disease"4 and because Banyan tends to offer herbs according to their Sanskrit names, Guggul is offered as Guggulu. There are many varieties of guggul-each with different uses-determined in part by the color and age of the gum.1 It is said that the potency of guggul lasts 20 years.4 Guggul is a very important herb in the Ayurvedic tradition and while it is rarely taken by itself, an entire class of medicines has been built around the use of guggul.1 Banyan Botanicals carries several of these traditional Ayurvedic formulas, known as guggulus-compounds made from a base of purified guggul in a synergistic combination of other herbs.
