Cancer comfrey

The leaves from the myrtle (Myrtus communis) make into a tea that is good for diabetes and also acts against cancer. For cancer, comfrey and aloe vera are added. It is said to be active against breast, limg, bone, and glandular cancers. 

Heinerman s penultimate chapter is titled Traditional and Clinical Therapies for the Treatment of Cancer. It is divided into sections on Vitamin-Mineral Therapy, Laetrile, Hoxsey Therapy, The Kelley Method, The Gerson Therapy, Essiac, Comfrey, and Chaparral. These subjects are also covraed in the several other books cited herein, such as WaltCTs (1993), Moss (1992), and Pelton and... 

Nevertheless, Foster and Johnson emphasize that comfrey also contains toxic pyrrolizidine alkaloids (PAs), as documented in Chapter 6. Although PAs will help stop bleeding, the negative effects outweigh the beneficial, for comfrey has been found to cause liver damage and produce cancerous liver mmors. Despite its long history in herbal medicine, no clinical smdies have documented any positive effects attributable to comfrey. Many studies, however, have demonstrated its liver toxicity. 

Rats fed diets containing 2 or 8% comfrey root for 12 weeks did not develop liver toxicity but did have a higher mutation rate in liver and lung cell genes, and expressed genes that were involved in liver injury and abnormalities, including liver fibrosis and cancer development (Mei et al. 2005,2006 Mei and Chen 2007).
