Muscadines aren't so much a medicine like you think of in a medicine cabinet, but are more of a preventative medicine like toothpaste and cavities.
Muscadines are a native grape of North America. They grow wild and do not produce as much juice as domestic grapes. Often this skin, pulp and seed is used for fertilizer but don't waste it that way. The entire Muscadine except the seed is a great source of resveratrol. Mississippi State University nutritionists found that a Muscadine puree made from Muscadines without the seeds is an excellent source of resveratrol, dietary fiber, and other essential minerals.
Research has shown that powdered Muscadine puree has a whole lot of dietary fiber and is known to lower blood pressure, serum triglycerides, and both total and LDL (bad) cholesterol levels. Consuming Muscadines protects against coronary heart disease, gastrointestinal diseases, and colon cancer. So eat Muscadines in whatever fashion you like, wine, puree, powder or jelly/jams as all are a great preventative medicine for a number of ailments mentioned above.
