Onion Overview
Onion, a common vegetable, has a long history of use in traditional medicine. It is believed to have a number of health benefits due to its high content of antioxidants, such as quercetin, as well as its anti-inflammatory properties.
It is often used to treat respiratory conditions, such as colds and flu, due to its expectorant and decongestant effects. It is also believed to be helpful in relieving symptoms of asthma and bronchitis and is thought to have antimicrobial properties, making it useful for treating infections and wounds. Additionally, onion is believed to help lower cholesterol levels, reduce the risk of heart disease, and improve blood sugar control. Most dietary supplements containing onion are an extract that contains allicin.
dabigatran Overview
-
Dabigatran is used to treat deep vein thrombosis (DVT; a blood clot, usually in the leg) and pulmonary embolism (PE; a blood clot in the lung) in adults and children 3 months of age and older who have been treated with an injectable anticoagulant ('blood thinner'). It is also used to reduce the risk of a DVT and PE from happening again after initial treatment is completed in adults and children 3 months of age and older. Dabigatran is used to help prevent DVT and PE in adults who have had hip replacement surgery. Dabigatran is also used to help prevent strokes or serious blood clots in adults who have atrial fibrillation (a condition in which the heart beats irregularly, increasing the chance of clots forming in the body, and possibly causing strokes) without heart valve disease. Dabigatran is in a class of anticoagulant medications called direct thrombin inhibitors. It works by preventing blood clots from forming in the body.
