I'm still getting strong reactions from the cat's claw. I know it is from the cat's claw, as the muscle ache and discomfort get much worse a few hours after I take it. On days that I need to be active, I skip the morning dose of cat's claw so that I am able to function.

One important thing about cat's claw. Women who are pregnant or who might become pregrant need to avoid cat's claw.
