Well, I never support the mainstream "search for a cure" groups because all the money they make ends up going for medical testing that is totally biased against holistic and true herbal healing.
Many in these campaigns are sincere, but they are never going to get anywhere near a cure unless they look into honest healing involving what God put here on the Earth-- and not corrupted pharmacuetical science.
The campaigns I will help are the local ones where a family is having some kind of small town fundraiser to help someone going through medical bill debt due to a life threatening illness.
