I have been championing the cause of melatonin for years now. An increasing number of studies indicate that melatonin protects normal cells from radiation and chemotherapy while at the same time reducing cancer-cell growth. It doesn’t get much better than that for an integrated cancer therapy. Which is why I now consider melatonin to be a standard for the treatment of all solid tumors. But what about the blood-based tumors, such as leukemia? A recent study looked at the answer to this question.

A few months ago, I told you about how olive leaf extract can help you lower your blood pressure naturally. I’m a big fan of this option, as I think it’s much safer than a lot of the blood pressure drugs on the market. Most of the research on olive leaf extract has been positive, and I’ve told you about some of those studies in the past. But occasionally, studies of olive leaf extract have had some inconsistencies. Researchers at the University of Reading, Massey University, and the Commonwealth Scientific Industrial Research Organization decided to try to get to the bottom of the olive-leaf debate once and for all.

Babies need vitamin A to help their hearts develop properly. But the effects of vitamin A on your heart after you’re born aren’t as clear-cut. Vitamin A does affect your heart in several ways – that much is known. But researchers haven’t yet decided whether the net effect of this vitamin on the heart is positive or negative. There have been plenty of studies conducted on this topic, but they seem to come to opposite conclusions. Whatever the final answer is, vitamin A is not a topic we should ignore.
