Urtica Dioica (Nettle) has long been used to treat high blood pressure. It stimulates the production of nitrogen oxide, which acts as a vasodilator. Vasodilators relax the muscles of blood vessels, helping them to expand. Nettle also contains compounds that can act as calcium channel blockers, relaxing the heart, reducing contraction power. Nettle has been shown to reduce blood pressure and simultaneously increase antioxidant protection of the heart.

Taurine is amino acid, the high content of which in the blood evidently inhibits inflammation and improves the elasticity of the artery walls, contributing to a decrease in blood pressure, inhibits platelet aggregation in the circulatory system, has a positive effect on overall cholesterol in the blood and lowers triglyceride levels, inhibiting the progression of atherosclerosis. Taurine also has a protective effect on myocardial cells.

Crataegus Laevigata is used for diseases of the heart and blood vessels such as congestive heart failure (CHF), chest pain, and irregular heartbeat. It is also may be used to treat both low blood pressure and high blood pressure. It acts as a vasodilator, so it can relax constricted blood vessels, eventually lowering blood pressure. It is also useful for "hardening of the arteries" (atherosclerosis), and high cholesterol.
