Samento is a concentrated extract of Cats Claw and I highly recommend it if you have Lyme. It is much more potent and effective, than ordinary Cats Claw extract. I have found Samento to be the best treatment for eliminating my Lyme symptoms, especially when taken with high doses of Vitamin C (3,000 to 5,000 mg per day for a few days). When I found out I had Lyme, I took Samento for a few weeks as directed. All my symptoms disappeared. Sometimes when I am getting run down, some of the symptoms return (aching muscles and stiff neck), but I just take Samento and Vitamin C again and I feel fine. From now on I will always keep Samento around!
