The only problem with that approach is the plant needs to be 5 yrs old. Cancer Can be Cured by Father Romano Zago talks all about how to prepare your own formula. There are other restrictions other than the 5 yrs stipulation.
These links will provide an introduction. I personally experienced seeing shock in a urologist's face with a PSA result he wasn't expecting. I had not told him I was now taking (this was in 2015) IP6 because he acted scornful of natural supplements and would not advise me. He was replaced when I moved with my wife from AZ to FL.
Remember to buy the powder not the capsules as you will need a heavy dose (the recommended dose on the canister is a preventive dose). Take it in water and stirred vigorously on an empty stomach (no food before for 2 hours). Avoid mixing with anything else particularly protein which can bind with the IP6 molecules. Do not eat anything for 1/2 to 1 hour. Good luck.
