Owen, I have heard of Cat's Claw for many ailments, many times, and have recently considered taking it for my health problems (mainly Crohns disease, which I've heard it can help). I think it is Rio Health in the UK that stock the Samento that you mention. Your messages have just made my mind up for me, and I'm going to order some. Thank you for the information, this could be a momentous discovery! I'll let you know of any developments.
