Feverfew Overview
Feverfew (Tanacetum parthenium) is a flowering plant belonging to the daisy family. It is native to Europe and has been traditionally used for a variety of medicinal purposes, including the treatment of fever, headache, and inflammation. Some studies have suggested that feverfew may help to reduce the frequency and intensity of migraines, although the results have been mixed.
Most feverfew dietary supplements are standardized for the parthenolide content, a lactone thought to be responsible for some of its effects.
Codeine Phosphate Overview
-
Codeine is used to relieve mild to moderate pain. It is also used, usually in combination with other medications, to reduce coughing. Codeine will help relieve symptoms but will not treat the cause of symptoms or speed recovery. Codeine belongs to a class of medications called opiate (narcotic) analgesics and to a class of medications called antitussives. When codeine is used to treat pain, it works by changing the way the brain and nervous system respond to pain. When codeine is used to reduce coughing, it works by decreasing the activity in the part of the brain that causes coughing.
-
Codeine is also available in combination with acetaminophen (Capital and Codeine, Tylenol with Codeine), aspirin, carisoprodol, and promethazine and as an ingredient in many cough and cold medications. This monograph only includes information about the use of codeine. If you are taking a codeine combination product, be sure to read information about all the ingredients in the product you are taking and ask your doctor or pharmacist for more information.
