I started using this product for blood pressure and it has been working. My last three blood pressure test from different doctors, was in the 120's over 70's. That used to be my norm. I may ween myself off after a few more tests as when I had a mussel test I was told it wasn't working for me. That may because I no longer need it. Hawthorne Extract seemed to be helping the high side and Chaga was helping the low side. The only reason I know that is because I ran out of Hawthorne Extract and couldn't get any. I hadn't taken any for about three weeks when I had my blood pressure taken, the high was 158 and the low was in the low 70's. When I started taking the capsules because I couldn't get the Hawthorn Extract my top pressure came back down.
