Rosemary Essential Oil is derived from the aromatic herb belonging to the mint family, which also includes basil, lavender, myrtle, and sage. It is orginally native to the Mediterranean and receives its name from the latin words “ros” (which means dew) and “marinus” (which means sea), the full meaning coming to “dew of the Sea.” It also grows in England, Mexico, the USA, and northern Africa, namely in Morocco. Known for its distinctive fragrance that is characterized by an energizing, evergreen, citrus-like, herbaceous scent.
Rosemary was once considered to be a sacred plant by ancient Greeks, Egyptians, Hebrews, and Romans. The Greeks used to wear rosemary garlands around their heads while studying, as it was believed to improve their memory, and both the Greeks and the Romans used rosemary in almost all festivals and religious ceremonies as a symbol of purity.
In the Middle Ages, rosemary was believed to be able to ward off evil spirits and to prevent the onset of the bubonic plague. With this belief, rosemary branches were commonly strewn across floors and left in doorways to keep the disease at bay.
It has also been used throughout civilizations in cosmetics for its antiseptic, anti-microbial, anti-inflammatory, and anti-oxidant properties as well as in medical care for its health benefits.
Rosemary had even become a favorite alternative herbal medicine for the German-Swiss physician, philosopher, and botanist Paracelsus, who promoted its healing properties, including its ability to strengthen the body and to heal organs such as the brain, heart, and liver.
