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.
Galantamine Overview
-
Galantamine is used to treat the symptoms of Alzheimer's disease (AD; a brain disease that slowly destroys the memory and the ability to think, learn, communicate and handle daily activities). Galantamine is in a class of medications called acetylcholinesterase inhibitors. It works by increasing the amount of a certain natural substance in the brain that is needed for memory and thought. Galantamine may improve the ability to think and remember or slow the loss of these abilities in people who have AD. However, galantamine will not cure AD or prevent the loss of mental abilities at some time in the future.
