Garlic tumor growth inhibition

When garlic is extracted by methanol, aUyl methyl trisulfane is formed. Unsaturated polysulfanes from Allium species inhibit the growth of certain tumors. ... 

Early in vivo experiments (1913) showed that garlic and its compounds acted against mmors in mice, with similar results obtained by others (Reuter, Koch, and Lawson, in Garlic, pp. 178-186). Not only could mmor growth be inhibited, but alliin as freshly obtained from garlic bulbs and directly injected into rat sarcomas, resulted in reduction and dissipation. Similar results were obtained for intramuscular injections. Others, however, reported otherwise. On the other hand, allicin deactivated ehrlich ascites mmor cells, and also deactivated cells of Yoshida sarcoma (a mammary tumor). Other examples are described in the reference, with the note that fresh garlic neutralizes cancer cell virulence without compromising the immune response, whereby atumals at least become immune to untreated mmor cells. 

In addition to its chemopreventive effects, some of the sulfur compounds in garlic also inhibit the growth of induced and transplantable tumors in animal models. ...
