Hawthorn Overview
Hawthorn is a shrub native to Europe, Asia, and North America. It is a member of the rose family and is known for its thorny branches and small, white or pink flowers, which bloom in the spring. The fruit, called a haw, is a small red berry that is edible and often used in traditional medicine. Hawthorn has been used to treat a variety of conditions, including gastrointestinal discomfort, heart disease, high blood pressure, and chest pain. For its purported blood pressure-lowering abilities, it is thought to work by dilating blood vessels and improving blood flow to the heart. Hawthorn dietary supplements are typically standardized extracts of the berry, leaf and flower of the plant.
Labetalol Overview
-
Labetalol is used to treat high blood pressure. Labetalol is in a class of medications called beta blockers. It works by relaxing blood vessels and slowing heart rate to improve blood flow and decrease blood pressure.
-
High blood pressure is a common condition and when not treated, can cause damage to the brain, heart, blood vessels, kidneys and other parts of the body. Damage to these organs may cause heart disease, a heart attack, heart failure, stroke, kidney failure, loss of vision, and other problems. In addition to taking medication, making lifestyle changes will also help to control your blood pressure. These changes include eating a diet that is low in fat and salt, maintaining a healthy weight, exercising at least 30 minutes most days, not smoking, and using alcohol in moderation.
