Elderberry Overview
Elderberry (Sambucus) is a plant that belongs to the Adoxaceae family. It is native to Europe, Asia, and North America, and has been used for centuries in traditional medicine. The Elderberry plant has distinctive dark purple or black berries, which are often used in different types of food, including jams, jellies, and syrups. In traditional medicine, elderberry is one of the most popular over-the-counter supplements due to its purported immune-stimulating effects and is used to treat colds, flu, and other respiratory infections. Some studies have suggested that elderberry may have antiviral and immune-boosting properties, but more research is needed to confirm these effects. It is important to note that there are several different species of elderberry, including American elder (Sambucus canadensis) and black elder (Sambucus nigra). Black elder is more commonly used in dietary supplements.
Atenolol Overview
-
Atenolol is used alone or in combination with other medications to treat high blood pressure. It also is used to prevent angina (chest pain) and improve survival after a heart attack. Atenolol 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.
