Help! looking for anyone with knowledge of natural program to reverse aids

There was a guy in my support group who was talking about doing a volunteer study program for an all natural product that reverses the aids illness. Once he started the program he never came back. I asked around and someone told me that they heard that the product worked and it was reversing the illness, this is why he never came back. I've been asking around but no one else knows what program it was because they weren't interested to join. I'm desperate at this point and want to find anyone with information on this. Can anyone help?
