My capsule story.
I have a very clever scientist brother-in-law. Some 15 years ago his wife was diagnosed with an aggressive blood cancer with a two-month likelihood of her death. He researched world wide (not just a quick Google enquiry). He was able to find four other scientists wrestling with cancer cures.
From India, Australia, Argentina (I think) and America, they were all working on the cancer-destroying properties of curcumin. One scientist (the American) had stopped his own cancer with curcumin 20 years before! So, my brother-in law, using their exchanged information and publicly available data, developed curcumin pills and gave them to his wife. He bought her about 12 full years with the capsules.When he learned that I had cancer he summoned us to learn how to make the pills. He did not feel that he could ethically make them for me.
With his guidance I sourced the equipment and ingredients. The two most important were the curcumin (which had to be 98% plus pure) and the capsules (which had to be acid resistant in order to pass through the stomach to the gut – and thence into the blood stream). The capsule suppliers that satisfied the stringent requirements were (and are still) sourced from DR T & T Health UK Ltd.
