Rosemary (Rosmarinus officinalis) is a perennial woody evergreen herb native to the Mediterranean region. The herb has a warm, bitter, and astringent taste but yet it gives a wonderful flavor and aroma to soups, sauces, stews, roasts, and stuffing. It can be used in dried powder form or as fresh leaves. Its leaves can be used to prepare tea, essential oil, and liquid extract. The most interesting health benefits of rosemary include its ability to boost memory, improve mood, prevent Alzheimer’s and cancer, reduce inflammation, relieve pain, and protect the immune system. The herb also helps stimulate circulation, detoxify the body, protect the body from bacterial infections, prevent premature aging, and heal skin conditions. The oil of rosemary promotes hair growth, prevents baldness, slows graying, treats dandruff, and dry scalp. It also promotes healing by increasing microcirculation of scalp and decreases hair loss after shampooing. It helps improve memory performance and quality. It is also known to boost alertness, intelligence, and focus. The carnosic acid in rosemary has neuroprotective properties. A study suggests that it helps to reduce oxidative stress and overstimulation in nerve cells, ultimately protecting the nervous system.  It is also known to protect certain parts of the brain from tissue damage such as ischemic injury, heals nervous tissue, and reduce blood clots.
