Health Science Institute carried a story a while back about a fry cook wanting to clean his fryer easily. He enlisted the help of a friend who was a chemist. After testing many plant extracts, he found Sea Buckthorn, a local shrub, provided the answer. The fryer was cleaned easily with the extract. Since Sea Buckthorn is non-toxic and may have medicinal properties - it seems logical to assume it may work wonders on one's cardiovascular system. It is wise to do one's own research about what one consumes. Drugs come with risks, while natural therapies like this appear to have less risk.
