Essiac is a tea made from four herbs. A Canadian nurse named Rene Caisse developed it in 1922. She said the formula originally came from an Ojibwa Indian medicine man. She named it after the backward spelling of her own last name, Caisse. The 4 main herbs in Essiac are burdock root (Arctium lappa), Indian or Chinese rhubarb (Rheum palmatum), sheep sorrel (Rumex acetosella), and the inner bark of slippery elm (Ulmus fulva or Ulmus rubra).
Burdock root is used in folk medicine to improve digestion, to clean the blood, to increase urination, or as a laxative. Laboratory studies have shown some anti-tumor effects. Rhubarb can be a strong laxative. Sheep sorrel is claimed to be effective against cancer. Slippery elm has a long, safe history in alleviating sore throats. It is used in many herbal cough drops or teas for sore throats.
Essiac is widely available as an herbal health food, without any specific health claims. There are several different versions of the product. There are also many claims and counterclaims about authenticity. In 2000, the US Federal Trade Commission filed a complaint against a distributor of Essiac for misleading health claims on several web sites.
A review of the scientific literature on Essiac concluded that there were no studies to support Essiacs traditional uses.
Many providers of Essiac claim that the only correct way to use the product is to drink a freshly brewed tea, one to three times a day on an empty stomach. Essiac is available in liquid form but is also sometimes sold as a mixture of herbs to be boiled and steeped by the user, or in capsule form.
Caisse reportedly had several variations of the recipe to treat different forms of cancer. Some versions of Essiac have more than the original four ingredients. The added ingredients are supposed to enhance the product's effectiveness and improve its taste. Two common additions are watercress and Pau d'arco. Yellow dock or curly dock are sometimes used instead of sheep's sorrel.
Advocates of Essiac suggest using it only if it is made in small batches with the freshest possible ingredients. They also disagree with using Essiac pills, capsules, or tea bags.
Proponents of Essiac claim that it strengthens the immune system, improves appetite, relieves pain, and improves overall quality of life. They also claim that it shrinks tumors and prolongs the lives of people with cancer.
