Hawthorn (various Crategus species) received an endorsement in another Ernst-and-friends metareview. The review included 14 trials, and focused on hawthorn's ability to improve the maximum workload of the heart, and improve various cardiovascular markers during exercise-induced strain. The bottom line: hawthorn leaf and flower extract helps. A lot. Even if added to existing medication regimens.Just to be clear, no new clinical research is coming out of this review. Rather, it attempts to collate existing studies and compare them using a common denominator. Further details on the data are below, but for now my opinion continues to be that hawthorn, either as a berry, a tasty jam, or as a leaf-and-flower extract (or tea), should always be considered as part of the protocol for cardiovascular weakness or imbalance. In fact, I might go further to say that most colorful berries would accomplish similar effects and that, in fact, a nice cocktail of all sorts of berry fruits is probably the best way to go for managing blood pressure, improving capillary integrity, and increasing the efficiency
of the heart muscle. Eat well!
