Cloves are good for cholesterol. Regardless of the amount of cloves consumed, all those who ingested cloves showed a drop in glucose, triglycerides and LDL ("bad") cholesterol levels. Blood levels of HDL ("good") cholesterol were not affected among the clove eaters
Cloves have also been shown to be an effective platelet inhibitor, thus helping prevent blood clots. Eugenol, a component of cloves, was found to be 29 times more potent than aspirin in preventing platelet aggregation. It also inhibited lipid peroxidation, a cause of heart disease.
