Many people use devil's club sold as a tincture. There are other herbs in it, too. New Rainbow Bridge used to sell Devil's Club Supreme by Gaia; apparently it is no longer sold. Azmira Animal Health sells the same stuff- they have their own names for their products. This is called Panc'rse & Glucobalance. You can call their order phone at 1-800-497-5665 or try online. Mary Jo D. has more information. Our vet was the one who recommended it. Just one drop twice a day helps a lot. I add it to the pred in chicken gravy with a speck of Nutri-cal to cover the taste. It smells bitter. Carol [Posted in FML issue 5191]
