Dandelion Overview

Dandelion Dandelion is a plant that belongs to the family Asteraceae. It is native to Europe, Asia, and the Americas, and is known for its distinctive, bright yellow flowers and puffy, white seed heads. Although considered a weed by many, it is considered valuable for a number of reasons as it can be used as food, in medicine, and to attract pollinators. Dandelion has a long history of use as a medicinal plant. It has been used to treat a variety of conditions, including liver and gallbladder problems, kidney disorders, skin conditions, and digestive issues. It is also purported to have a diuretic effect and dietary supplements containing dandelion often market it for being able to help reduce water retention.

Prescription naproxen tablets, extended-release tablets, and suspension are also used to relieve shoulder pain caused by bursitis (inflammation of a fluid-filled sac in the shoulder joint), tendinitis (inflammation of the tissue that connects muscle to bone), gouty arthritis (attacks of joint pain caused by a build-up of certain substances in the joints), and pain from other causes, including menstrual pain (pain that happens before or during a menstrual period). Nonprescription naproxen is used to reduce fever and to relieve mild pain from headaches, muscle aches, arthritis, menstrual periods, the common cold, toothaches, and backaches. Naproxen is in a class of medications called NSAIDs. It works by stopping the body's production of a substance that causes pain, fever, and inflammation.
