Abstract: The present invention relates to a composition including decursinol as an active ingredient for preventing or treating angina, arteriosclerosis, cerebral infarction, and hypertension. Poorly soluble decursinol was found to improve angina, arteriosclerosis, cerebral infarction, prostate hypertrophy, and diabetic hypertension by inhibiting the overgrowth of vascular endothelial cells, and is expected to be usable in the development of a composition for preventing or treating angina, arteriosclerosis, cerebral infarction, prostate hypertrophy, and diabetic hypertension.
