Dear John
By and large you are right in your reference to Hoodia Gordonii as it really does depend on which manufactured goods containing Hoodia Gordonii you buy/use.
Unfortunately, unscrupulous trading practices have seen this wonderful plant become the subject of controversy as all products with the exclusion of GCT products, now contain other substances.
In our trials, we found that by using the entire plant and not just isolating the P57, and putting it through our DCD process, we are able to break the cell structures down to a molecular level making the plant as a whole more effective.
We have also been able to determine and prove that the use of the plant as a whole leads to some remarkable benefits such as lowered blood pressure, lowered cholesterol as well as stabilisation of blood sugars which overall promotes better sleeping habits, better focus, improved bowel movements and appetite control rather than suppression. Just as a note of interst, the P57 active ingredient was patented by the South African CSIR. Hope you find this helpful – kind regards Kaz
