This homeopathic remedy is made from cancerous tissue, usually obtained from the breast. Cancer is the second most common cause of death in the Western world (after heart disease). The development of a homeopathic remedy derived from cancerous tissue is attributed to two British homeopaths, Dr. Compton Burnett and Dr. Clarke, who first proved the remedy in the late 19th century. Its uses have widened considerably following work by Dr. D. M. Foubister of the Royal London Homeopathic Hospital and research published by the US homeopath Dr. J. Shore in 1989. Carcinosin is thought to be particularly beneficial for noncancerous conditions in people who have a strong family history of cancer. Carcinosin is best suited to people who were shy, over sympathetic, and hypersensitive during childhood, Such children typically suppress their emotions, dislike being criticized or scolded, and are easily offended. During puberty they may find it difficult to contain their sexual feelings. As adults, they tend to be passionate, and often become workaholics, continually pushing themselves to the limit. They may have a great desire for travel and excitement. Their yearning for deep fulfillment may lead to exhaustion and illness. People who benefit most from the remedy may have a strong craving for fatty foods, especially butter and chocolate. Physical symptoms may be positively or negatively affected by being at the seaside.
