Hawthorn berries (Crataegus spp.) have been a part of traditional healing for centuries, with a long-standing reputation for having a positive impact on heart and circulation function.
In recent times, scientific studies are proving long-standing claims, with studies finding that Hawthorn extract can actually lower blood pressure and enhance cardiovascular function. Let’s review the scientific studies that detail the use of Hawthorn berries in treating high blood pressure and see why it has such a long-standing heritage in traditional medicine.
The berries in Hawthorn have vasodilatory compounds such as flavonoids and oligomeric procyanidins, whose function is to widen blood vessels, lower arterial tension, and stimulate the production of nitric oxide, all of which contribute towards lowering blood pressure. Hawthorn possesses a mild diuretic property, and its use helps in controlling blood pressure levels even more effectively.
Clinical studies have examined Hawthorn’s efficacy in mild to moderately hypertensive subjects with some nice results. As a complementary therapy and not a complete substitution for conventional antihypertensives, Hawthorn can serve as a beneficial alternative for anyone interested in a natural remedy.
A 2012 randomized double-blind placebo-controlled study by AIA Al-Gareeb explored Hawthorn extract’s effects on stage I hypertensive patients. It was observed that there was a significant reduction in systolic and diastolic blood pressure compared to the placebo group. Moreover, the patients also had improved lipid profiles, including lowered LDL cholesterol levels, pointing towards Hawthorn’s cardiovascular-supportive role. [Read the study.]
Another clinical trial conducted in 2021 by M. Abbasi and colleagues tested the effects of Hawthorn extract on blood pressure and sleep in hypertensives. Results revealed a noteworthy reduction in blood pressure and enhancement of sleep, depicting further beneficial effect on general well-being. [Read the study.]
The study, “Effect of Crataegus oxyacantha Extract on Digoxin-Induced Arrhythmias in Anesthetized Wistar Rats,” aims to investigate the antiarrhythmic potential of Hawthorn (Crataegus oxyacantha) extract in mitigating cardiac toxicity caused by digoxin. Digoxin is a widely used cardiac glycoside for treating heart failure and arrhythmias, but in excessive doses, it can lead to life-threatening cardiac arrhythmias.
The precise mechanism by which the extract exerts its antiarrhythmic effects remains unclear, but researchers hypothesize that it may involve calcium regulation, antioxidant activity, and modulation of ion channels in cardiac cells.
