Rosemary was the favorite plant of German-Swiss botanist and physician Paracelsus, who believed that it was an overall strengthening herb for the entire body, and internal organs in particular. Rosemary essential oil has a lovely and very aromatic smell that is both appetizing and refreshing. It stimulates hair growth, nourishes the scalp and is believed to slow down premature hair loss. Thus, it is a wonderful addition to hair care formulas of all kinds, and can even be used on its own as a rinse. Rosemary is also a calming essential oil that relieves stress by lowering cortisol levels in the body, and can be used as an antibacterial and immune system boosting oil as well.
