Essiac, given its name by Rene M. Caisse ("caisse" spelt backwards),
consists of four main herbs that grow in the wilderness of Ontario,
Canada. The original formula is believed to have its roots in native
Canadian Ojibway medicine.
The four main botanicals in Essiac tea - sheep sorrel, burdock root, the inner bark of the slippery elm and Indian Rhubarb - are each purported by herbalists to have beneficial effects. Sheep sorrel supports the endocrinal system. Burdock root apparently eliminates free radicals and purifies the blood. Slippery elm is believed to help maintain a healthy inflammatory balance in membranes and organs. And Indian rhubarb reportedly helps the body, especially the liver, rid itself of wastes and toxins.
The four herbs may help normalize body systems by cleansing the blood, purging toxic build up, promoting cell repair and aiding in effective assimilation and elimination. When combined it is believed that their separate beneficial effects are enhanced.
