Olive tree leaves contain a variety of active compounds shown in clinical trials to lower blood pressure and bad (LDL) cholesterol. In addition, reputable peer review journals report that olive leaf extract does kill bacteria and viruses in the tube, meaning the extract will kill a bacteria or virus grown in a lab dish or tube, and an NIH study is under way to determine if olive leaf extract inhibits cancer growth. Should folks interested in good health swallow olive leaf extracts? Maybe. Olive leaves have been used medicinally for thousands of years primarily in ancient Egypt and other Mediterranean cultures. The leaf extract can be taken as a liquid or powder supplement or in pill and capsule form. Smokers (even closet smokers [see examiner.com/longevity examiner/closet smoking is killing Roanokers] and cigar smokers) might do well to take olive leaf extract because cigarettes, as most people know, increase blood pressure and bad cholesterol. Adverse side effects of olive leaf extract include excessively low blood pressure and blood glucose. Anyone who has low blood pressure normally or who is hypoglycemic should probably avoid olive leaf extract. Nutritional supplements, especially those used for thousands of years, may very well have the qualities ascribed by testimony and may be a very viable alternative to overly potent and expensive synthetic pharmaceuticals. However, to depend on the underlying studies as proof of efficacy, one must question whether the compound investigated works only in a dish or whether it actually shows potency in living human beings. After all, bleach kills bacteria and viruses in the dish but is not recommended as an antibiotic.
