Humm just watched the doctor from your links and he said herbal remedies might not be effective if you have an impaired stomach. I've had two major operations on my stomach and one small one, my pancreas is shot, oh and I've had gastroenteritis a few times. Don't know why I'm writing this because if they end up not working there's nothing I can do about it.
So I'll keep on smiling through the purple haze and get on with it.
