Method of manufacture of garlic extract for use as a preventive and therapeutic agent for human prostate and bladder cancers

Abstract

This invention is concerned with clinical investigation of therapeutic effects of garlic extracts containing allicin, diallyl disulfide, and diallyl trisulfide. Because the intake of garlic or therapeutically active substance such as allicin from garlic, induces immunostimulation and possess strong antitumor effects concomitant with apoptosis of tumors that can in turn induces a programmed cell death of human prostatic and bladder tumor cells. This invention claims that garlic and/or garlic extracts possess very effective therapeutic substances not only to treat human prostate and bladder cancers to extend life span of patients, but also to suppress or prevent bladder and prostate gland cancers.

What is claimed is:  
     
         1 . A chemopreventive and chemotherapeutic composition against human prostate cancers comprising allicin-containing garlic extracts isolated and purified from garlic, as an effective ingredient.  
     
     
         2 . A chemopreventive and chemotherapeutic composition against human bladder cancers comprising allicin-containing garlic extracts isolated and purified from garlic, as an effective ingredient.
