I highly recomend these. This really works Posted by 5479302713122314152 on Jul 06, 2012 | Verified Purchase This is a fabulous product. I suffer from high blood pressure and three months ago it had reached 155/95. I started taking this Hawthorn product twice a day with Kyolic garlic capsules and now my BP is consistently 118/74 and normal. This proves that you can achieve results as good or better than prescription medicines.
