Bests & Worsts Reviews from Amazon

Apparently, some reviewer of this PawPaw extract believe it can cause tardive dyskinesia.... --- commonly seen as involuntary or negative body movements (such as involuntary blinking, tics, etc.). Where he ever obtained this information is unknown, --- because he never cited a literature source (for the fruit, possibly; for the twig; no). The major causes of TD are two types of medications used over an extended period of time: (1) anti psychotic drugs (2) tranquilizers This PawPaw extract of the PawPaw twig (the twig, not the fruit)fits neither profile, --- but if you are on these types of medications, don't expect any changes with your TD because of this PawPaw. As to the reviewer's comments about the "cytotoxcity" of this PawPaw extract, --- PawPaw is cytotoxic to cancer and tumor cells...cytotoxic defined as a "toxic effect preventing their growth"... --- particularly trilobacin, one of PawPaw's many acetogenins (which are also antineoplastic in nature). Please try to understand the difference here between "general cytotoxins" and what we are talking about here... --- very different. The basic idea behind this extract is to lower ATP levels,as well as to attack MDR tumors, --- the assumption being that cancer cells feed on ATP (therefore, the lower the ATP level, etc.) MDR tumors refers to "multiple drug resistant" tumors...a very common problem... --- commonly occurring subsequent to ADT therapy protocols for such cancers as prostate. To my knowledge, --- no extensive clinical trials on humans have been undertaken with PawPaw as of December, 2013... Is this extract a "magic bullet" that will kill all cancer cells? --- not suggesting it is because multiple variables impact the growth of cancer cells in humans. credentials of this reviewer: Ph.D. in Biochemistry from the University of Chicago, BS in Chemistry from Brown University (Providence, RI)
