Well, MattN, I really cannot imagine what you think that your reference to John McDougall brings to the debate. Dr John McDougall is a qualified physician who advocates a particular diet. You could say exactly the same for Terry Wahls - they each believe that their particular diet has cured themselves, and are telling anyone who is interested about that diet. They do not sell anything that a rational person could construe as a drug. The mistake that the cherry growers made is probably that of failing to take legal advice before promoting their product in a particular way - by attempting to quote the science behind their product (and hence it's benefits), they did in fact position their product into the category of drug or medication. You, it would seem, are tending to confuse a product with a service.
You ask if I believe the Gerson therapy to be effective. Yes, it is certainly effective at putting people into hospital. Just remember for a moment that one of the only two licensed clinics that offer the Gerson therapy is in Tijuana, Mexico, and then ask yourself why they have had to send people over the border to hospital in San Diego.
To quote from Cancer Research UK:
"Available scientific evidence does not support any claims that Gerson therapy can treat cancer. In fact, Gerson therapy can be very harmful to your health."
Or, to quote from the American Cancer Society, who go into more detail:
"Gerson therapy can be dangerous. Coffee enemas have been associated with serious infections, dehydration, constipation, colitis (inflammation of the colon), electrolyte imbalances, and even death."
And, no, I did not feel that the "cherry producer question" had been put to rest. What I said was that jimmylegs had addressed it. Maybe you should read the thread behind the link that jimmylegs gave.
