Research suggests coumarin may also be useful as an antidiabetic agent. Recent findings show both natural and chemically synthesized coumarin can protect pancreatic cells from damage. They also improve abnormal insulin signaling, which dramatically increases the effectiveness of insulin. Researchers are hopeful future medications can benefit from this characteristic, thus alleviating many of the complications and issues that diabetes causes. There may still be some unknown negatives associated with coumarin, so research is ongoing.
