Devil's Claw Overview
Devil's claw (Harpagophytum procumbens) is a plant native to southern Africa and a member of the Pedaliaceae family. The plant has large, lobed leaves and produces small, purple flowers. It gets its name from the small, hard, black seeds that are contained within the plant's fruit, which are shaped like small claws or hooks.
In traditional medicine, devil's claw is purported to have anti-inflammatory and analgesic (pain-relieving) properties. It has been used to treat a variety of health conditions, including arthritis, joint pain, and lower back pain.
Ranitidine Bismuth Citrate Overview
-
Ranitidine is used to treat ulcers; gastroesophageal reflux disease (GERD), a condition in which backward flow of acid from the stomach causes heartburn and injury of the food pipe (esophagus); and conditions where the stomach produces too much acid, such as Zollinger-Ellison syndrome. Over-the-counter ranitidine is used to prevent and treat symptoms of heartburn associated with acid indigestion and sour stomach. Ranitidine is in a class of medications called H2 blockers. It decreases the amount of acid made in the stomach.
