text: I used to get sick every year, whether I got a "flu shot" or not. Then a couple years ago I had a massive eruption form on my arm at the injection site. I began taking Cat's Claw (Uno de Gato) at the first sign of illness and haven't been sick since. (Or had any more ugly sores on my arm from toxic vaccinations.) Not all vaccines are toxic, but not all are benign, or even effective, either. Cat's Claw is cheap and even available in bulk at herb stores.
