However, preliminary research suggests eating curry leaves may help prevent Alzheimer's disease. A rat study found that curry leaves not only protected against future brain cell damage, but also corrected some of the consequences of previous brain cell damage. Other studies have shown similar results in human cells. Curry leaves are a popular spice in India and many Indian dishes include this leaf or another member of the mint family. Traditionally, they are used as a garnish for rice and other vegetables, but today they are often added to meat dishes as well. The potential benefits of curry leaves for preventing Alzheimer's disease have yet to be confirmed by additional studies, but if these initial findings are confirmed, it could lead to new treatments for this condition. People who want to add more spices to their diets could try adding curry leaves to their cooking. Or you could drink curry leaf tea instead! There are several recipes for curry leaf tea on the Internet. One recipe calls for boiling one teaspoon of dried curry leaves in two cups of water for five minutes, then straining them out and drinking the liquid immediately. Some people may have an allergic reaction to curry leaves, so check with a physician before trying this diet change.
