The role of Chemotherapy is to directly attack and kill the rapidly growing cancer cells using chemical agents. These agents are basically strong poisons and they quickly put a serious strain on the Canine metabolism and immune system as the body tries to break these poisons down and get rid of them. A collapse of aspects of the immunity is the fundamental cause of all cancers and it is important to reverse this as soon as possible to offer the best chance of healing. One of the best strategies during and after chemotherapy is to rid the body of dead cells and other toxic by-products of this treatment while supporting the return of healthy tissue. The herbal Chemotherapy support formulation includes the herbs; Chamomile, St Mary's Thistle, Alfalfa, Rosehips, Thuja, Parsley, Fennel, Blue Flag, Ginger and Liquorice. I also include the Bach Flowers; Rescue Remedy, Walnut, Wild Oat, Scleranthus, Honeysuckle and Crab Apple. The fact is, that the chemotherapy does its work and the Herbal Mixes assist the dogs system by minimising the side effects.
