American White Water Lily Overview

American White Water Lily Nymphaea odorata, also known as the American white water lily, is a North American aquatic plant with fragrant white flowers that float on the water's surface, accompanied by large, round leaves. It is found in ponds, lakes, and slow-moving streams, providing habitat for aquatic life. In traditional medicine, the rhizome and root of the American white water lily have been used topically for vaginal conditions, throat and mouth diseases, and as a poultice for burns and furuncles. The plant contains tannins, contributing to its astringent and antiseptic properties. Active components include nymphaeoside A, icariside, flavonols like afzelin and myricitrin, as well as alkaloids, gallic acid, mucilage, starch, gum, resin, sugar, ammonia, and tartaric acid. Afzelin, in particular, has been investigated for its potential role as an anti-prostate cancer agent.

Verapamil Overview

  • Verapamil is used to treat high blood pressure and to control angina (chest pain). The immediate-release tablets are also used alone or with other medications to prevent and treat irregular heartbeats. Verapamil is in a class of medications called calcium-channel blockers. It works by relaxing the blood vessels so the heart does not have to pump as hard. It also increases the supply of blood and oxygen to the heart and slows electrical activity in the heart to control the heart rate.

  • 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.
