Rosemary Oil Benefits – According To Science

 

In ancient times, rosemary – the Latin term for “Dew of the Sea” – was prized by the Greeks, Egyptians, and Romans. The ancient Greeks and Romans believed it could improve memory, while the ancient Egyptians used the fragrant evergreen in their rituals.

Today, rosemary and rosemary essential oil is used in a variety of ways, like flavoring, fragrance, and disinfectant to name a few.

Here are a few initial studies that show some of the benefits of rosemary essential oil. 

Rosemary Essential Oil May Improve Short-Term Memory

A small study of 79 students ages 13 to 17 found that rosemary essential oil improved their short-term image and numerical memory.

The researchers grouped the students into 3 groups. The first group was the control group, the second group was sprayed with lavender essential oil, and the third group inhaled rosemary essential oil. Afterwards, the students were quizzed on a series of visual and numerical memory tests. They found that both essential oils significantly increased the image memory of subjects compared to the control group. However, in the numerical tests, the rosemary group recorded higher median values compared to the control or the lavender group.

Rosemary Oil May Repel Mosquitos 

A systematic review published in 2019 looked at the effectiveness of plant-based repellents against Anopheles mosquitoes. Rosemary was one of the plants studied. The review examined 2 studies on the repellency effectiveness of rosemary and noted that a 20% oil solution of rosemary provided protection against An. stephensi for 8 hours. They noted that another study supported the claim that rosemary at 1, 2.5, and 5 mg/cm2 concentrations completely repels An. subpictus for 1, 1, and 1.5 hours, respectively.

Rosemary Essential Oil May Be Antimicrobial

Studies have shown the bacteria-killing activity of rosemary essential oil against E. coli, Staphylococcus aureus, Salmonella choleraesuis, and other nasties.

Rosemary and other essential oils weaken and damage the cell membrane of bacteria. Rosemary essential oil was noted to also inhibit the growth of certain bacteria.

The Bottomline

The studies mentioned in this article were not conducted on Sapadilla products or Sapadilla products containing rosemary essential oils, and further tests are needed to verify these claims.
