ウメ
"Prunus mume" is a common fruit in Asia and used in traditional Chinese medicine. It has long been used as a traditional drug and healthy food in East Asian countries. A recent study has indicated that "Prunus mume" extract is a potential candidate for developing an oral antimicrobial agent to control or prevent dental diseases associated with several oral pathogenic bacteria. Recent studies have also shown that "Prunus mume" extract may inhibit "Helicobacter pylori", associated with gastritis and gastric ulcers. Experiments on rats suggest that "P. mume" extract administered during endurance exercise training may enhance the oxidative capacity of exercising skeletal muscle, and may induce the muscle to prefer fatty acids for its fuel use rather than amino acids or carbohydrates, thus assisting endurance.
