I must share this with anyone who is interested in stopping the growth of tumors. My brother has a massive tumor 15 cm in his liver. Prior to using the San Pedro Cactus along with two other supplements, his tumor has stopped growing. It grew almost it's double size in two months, and now it appears to be staying put. Our hope is that his tumor shrinks to an operable size. His tumor has encased his a portal vein, biles, and other sensitive areas. Doctors need it to shrink. We are big believers in natural and herbal remedies to aide in this monsterous battle. The cactus can be purchased online, simply enter it's name and information will come up how to buy it. A word of advice. If you get a call back on your order verifying it, don't say you what you want it for. I placed an order for 13 arms of the cactus, and when I made the mistake of sharing what I wanted it for, It wasn't sold to me. Simply say your'e into cactus and want it for your yard. It is known to grow in Arizona and Mexico, strangely enough my sister later found one plant only at Home Depot for $50. The 13 arms were going to run me $150. We know of a family friend who had a brain tumor, and he was given months to live, he has now been with us for over 15 yrs. His tumor has is still there, but it is "dormant", it hasn't grown a cm in all these years. He religously drinks this stuff like water. Think slices of the cactus are cut into rounds and boiled with water. Leave the slices in the water, place in sealed pitcher, refridgerate, and drink up. My brother is also drinking another concoction of a form of mushroom brought in from Mexico. It has helped others ward off the cancer. Hope this helps you as well.
