Where to find herbals...

A lot of the places that were recommended were out of stock of cat's claw. I did order fine powder cat's claw to make pills but it is non-standardized (2.5%) so I'm looking now for the 10% standardized cat's claw - any ideas?

I use amazon.

This is the cat's claw product I use. It is 1.5% standardized, but also 10:1 concentrate.
