11 Amazing Benefits of Rosemary Oil

Rosemary oil is one of the most popular essential oils for its wide array of health benefits.

Rosemary, also known as Rosmarinus Officinalis, is very popular in the Mediterranean region as a culinary herb. Many dishes are cooked with rosemary oil and freshly plucked rosemary leaves. Rosemary essential oil is mostly extracted from the leaves. The rosemary bush belongs to the mint family which includes basil, lavender, myrtle, and sage.

Rosemary has been extensively used since ancient times for a variety of purposes. The Romans gave special importance to the rosemary plant and used it frequently in religious ceremonies. It was also used during wedding ceremonies, food preparation, cosmetic care, and medicinal herbal care. Rosemary plant and its extract were also used by the ancient, Egyptian civilization as incense.

The health benefits of rosemary essential oil made it a favorite of Paracelsus, a renowned German-Swiss physician and botanist, who made significant contributions to the understanding of herbal medicine during the 16th century. Paracelsus valued rosemary oil due because of its ability to strengthen the entire body. He correctly believed that rosemary oil had the ability to heal delicate organs such as the liver, brain, and heart.

Stress Relief: Aside from the relaxing nature of aromatherapy and general inhalation of rosemary essential oil, it has been proven to actually decrease the level of cortisol in the saliva. Cortisol is one of the main stress hormones that are released during the “flight or fight” response of the body to stress.

A study released in 2007 said that inhaling rosemary oil and lavender oil for five minutes significantly reduced the levels of cortisol in the test subject’s saliva, which could seriously decrease the dangers inherent from chronic stress.

Immune System Boost: Antioxidants are some of the most valuable defensive weapons we have in our body for fighting off infection and disease, so any food or essential oil that either adds to or stimulates the activity of antioxidants is a huge benefit to overall health. The same study which found that cortisol levels decreased after simultaneous massage and inhalation of rosemary essential oil also found that the scavenging free radical activity in the test subjects’ bodies also increased significantly. This means that regular use or inhalation of rosemary essential oil in aromatherapy sessions or in other ways can increase the strength of the immune system and help combat all of the diseases associated with free radicals, including cancer and heart disease.

In an oil burner, what ratio do you use, of rosemary oil to water?


never heat oils once you do they can lose some if not all of their therapeutic benefits. this is why nearly all people that use therapeutic grade oils use a cold water diffuser, not an oil heater, warmer or burner. Rosemary oils is considered a hot oil so you would only use 1-2 drops max (in some countries including the USA, a bottle of oil only has to have 5% of the actually plant oil it in to be considered pure oil (its sooooo wrong as the other 95% could be anything including synthetic oils) make sure you go with a company who make pure therapeutic grade oils (which you wont find over the counter, you would need to join as a member to purchase their oils, but definitely worth it.


I have begun to inhale Rosemary extract from essential oil bottle-- three deep breaths twice a day. Helps sinus condition.
As for memory, there is insufficient scientific evidence. So much hype is presented as "fact."


This is awesome


I started using this a few days ago in a vaporizer because of its purported benefits to memory. I didn't know anything about any other positive effects it might have, but I can testify to a definite mood improvement and more mental energy. I just feel good all day long. I'm not sure yet if it's aiding my old brain to remember things, but I plan to continue its use.


don't use the oils in anything that heats the water/oil. doing that you lose most of the health benefits of the oil. Use a cold water diffuser.


I don't see any references. I'd love to find a reliable source for rosemary's effect on sore throats.
