I've known Jeff & Wendee for years and know them to be completely honest and trustworthy; therefore, I trust their product to be what it says it is. I have used the salve, which is helpful to me, the 1000 mg lotion, which really works well on my hip bursitis, and now the roll-on product which has really helped my trigger finger to be less painful while I wait for the procedure to fix it. I recommend Cornerstone Botanicals for everyone and would give them 10 stars if it was possible!
