Are there problems with essiac when taken with other drugs?
Many people are concerned that there might be problems with essiac together with other drugs. Although nothing has ever led us to believe essiac is not totally safe, you should always let your doctor or health care provider know you are taking it, as well as any other supplements, herbs, vitamins, etc. you may be using.
An excellent source for drug/herb interactions can be found in the book Herb Contraindications And Drug Interactions, Second Edition (Paperback) by Francis Brinker.
Essiac problems or interactions are not well studied scientifically. Most potential interactions are based on theoretical and known reactions associated with herbal components of essiac: burdock root ( Arctium lappa ), sheep sorrel ( Rumex acetosella ), slippery elm bark (Ulmus fulva), and Turkish rhubarb ( Rheum palmatum ). However, the interactions of these individual herbs are also not well studied. Our formula also contains blessed thistle (Cnicus benedictus), kelp (Laminariales) , red clover (Trifolium pratense), and watercress (Nasturtium officinale).
