Were the Ancient Greeks and Shakespeare Right?
In Greek mythology, the story that led to the birth of Aphrodite, the goddess of love and beauty, also gave rise to the creation of rosemary.
Kronos, the youngest of the 12 Titans, ended his father’s reign by severing his masculinity with a sickle and casting it into the sea. It was from the foam that emerged in the Aegean and Mediterranean waters following this act that Aphrodite was born. Rosemary, too, began to grow in the very places where these foams washed ashore.
In addition to its role in mythological stories, it is also said that in ancient Greece, students would wear rosemary crowns, especially during exams, to enhance their concentration and memory. You might even see rosemary adorning the heads of brides from time to time.
Traces of rosemary can also be found in great literary works. In William Shakespeare's Hamlet, the beautiful Ophelia says to her brother Laertes:
- There’s rosemary, that’s for remembrance; pray, love, remember.
Rosemary essential oil, nearly as ancient as the use of rosemary itself, is composed of rich chemical compounds. While its composition varies depending on the region where it is produced and the distillation method used, the main active components are 1,8-cineole (30-50%), camphor (10-20%), and alpha-pinene (10-25%).
According to a study (1) analyzing the results of 76 different aromatherapy studies involving 6,539 participants, it was found that in 70% of the studies, participants who received aromatherapy experienced a reduction in stress levels compared to those who did not.
Aligned with literary and mythological narratives, there are also studies suggesting that inhaling rosemary essential oil improves memory and cognitive performance while reducing stress and anxiety. In an experiment involving 20 volunteers (2), changes in participants’ mood and blood values were recorded at the beginning and end of the trial. Results revealed a linear relationship between increased levels of 1,8-cineole in the blood and improved logical reasoning and visual information processing performance. This supports the idea that the compounds in rosemary essential oil independently influence cognition and subjective states through different neurochemical pathways.
Another fascinating scientific study in this field (3) focuses on the effects of aromatherapy using rosemary and lavender essential oils. Conducted on 337 students during their graduation exams, the results revealed that rosemary essential oil reduces levels of cortisol, also known as the stress hormone, thereby protecting the body from oxidative stress. Here are the details:
In the first exam, no intervention was applied to the students, while during the second exam, students were allowed to inhale lavender essential oil through a breathing device. The third exam was conducted using rosemary essential oil. Before and after all the exams, students underwent a test for performance anxiety, and their pulse and blood pressure values were recorded.
While no significant difference was observed between the pre and post-measurements of the first experiment, the results of the second and third experiments revealed notable differences.
-
The results of the performance anxiety tests in the second and third exams indicate that students who received aromatherapy experienced a reduction in stress levels.
-
Post-exam pulse measurements also show a noticeable decrease in the second and third exam.
-
While blood pressure, known as an indicator of prolonged stress, did not show a significant difference between pre and post-exam values, the fact that it remained stable is interpreted as a sign of low anxiety levels.
In summary, scientific studies show that rosemary and its essential oil offer numerous mental and physical benefits, in line with its traditional uses.
