Rosemary, That's for Remembrance

As famously quoted from Shakespeare's play Hamlet "There's Rosemary, That's for Remembrance; Pray you Love, Remember", Rosemary has been around since ancient times and long known for it's properties of improving memory and stimulation of the nervous system. Now science is beginning to prove that rosemary essential oil may improve the ability to remember things that will happen in the future as well as long term memory.

On April 9th at the Annual Conference of the British Psychological Society in Harrogate,  the findings of a small study, by Dr. Mark Moss and Jemma McCready, were presented on how the aroma of rosemary essential oil may improve prospective memory in healthy adults.

Basically, the scientists were looking to see if blood levels of a compound in rosemary (1,8 cineol, also known as eucalyptol) were related to performance levels and changes of mood after exposure from a diffuser and how this affected the ability to remember to do certain tasks at a certain time in the future (prospective memory).

What the results of the experiment revealed was that those in the study who had been exposed to the diffused rosemary essential oil  did better on the tests to remember to do certain tasks at a particular time during the experiment and that the higher levels of 1,8 cineol in their blood suggested that this difference was pharmacological.

Now this is all fine and dandy, but what does it mean to you?

Using an aromatherapy diffuser, whether electric, candle or a diffuser ring on a light bulb, it allows the therapeutic benefits of the essential oil to enter the body via the nose and lungs just as in an aromatherapy shower. The advantage of using a diffuser is that you are not just scenting the air, you are getting the therapeutic benefits of your essential oils. By choosing essential oils that are high in 1,8 cineol to use in a diffuser such as eucalyptus, rosemary, or marjoram, you can possibly enhance your memory and recall.

How to Use a Diffuser

If you have an electric diffuser, follow the manufacturer's instructions.

For a candle diffuser: place some water in the top, but not to the rim as you need room for the essential oils. Add 5-8 drops of your essential oil(s) to the water and place lit tea candle underneath. Keep an eye on the water level as the candle causes the water to evaporate - you don't want it to run dry because burnt essential oils smell awful.

For a diffuser ring: place 5-8 drops of essential oil on the ring and place on (or over) a regular light bulb that's turned on - the heat from the bulb will cause the essential oils to diffuse into the air. (This type of diffuser is handy for the office)

Other forms of diffusers include wall plug in types like the Glade ones but using a pad, car diffusers (some just like the Febreze vent clips and those you plug into a car lighter socket), pocket diffusers that look like the Vick's inhaler tubes and Berger Lamps.
