Rosemary Essential Oil Raw Ingredients


Rosemary (Rosmarinus officinalis) is a plant belonging to the Mint (Lamiaceae) family, the same one as Sage, Lavender and Basil. It is an aromatic herb with a woody fragrance and green, needle-like leaves. In bloom, it has white, pink, blue or purple flowers. Its name comes from the Latin ros meaning “dew” and marinus meaning “sea,” translating to “dew of the Sea.”


Rosemary is a very popular cooking and baking ingredient, but its uses as an essential oil go beyond common household knowledge.

1. Diffusing Rosemary Essential Oil Can Improve Brain Function

Who doesn’t want their brain to work a little better? Studies have shown that rosemary essential oil can help improve cognitive function, increase mental clarity, boost memory and improve speed and accuracy of mental tasks.

According to, diffusing rosemary essential oil “helps prevent the breakdown of acetylcholine, a brain chemical important for thinking, concentration and memory.”

Some research has also shown that it can be used in a blend with other essential oils to help with some neurodegenerative brain diseases by improving “brain function in older adults with dementia, including those with Alzheimer’s disease.”1

To boost memory, clarity and cognitive function, you can use just rosemary oil, but if you’d like to try making your own blend at home, we recommend testing it out with different ratios of lavender, peppermint, lemon, or grapefruit essential oils.

2. Stress Relief

Work piling up? Big date coming soon? Have a presentation or a big meeting tomorrow?

Plug in your diffuser, drop in some rosemary essential oil, and let its therapeutic stress relieving properties do the rest!

Studies have shown that rosemary essential oil can be a powerful stress fighter. One studies was done that showed breathing in rosemary oil while stressed lowered the heart rate at an average of 9%. Another study was done where researchers tested the saliva of participants after inhaling rosemary oil for 5 minutes and the study found that they had “23% lower levels of the stress hormone cortisol compared to those who smelled a non-aromatic compound.”1

According to Healthline, heightened levels of cortisol can “suppress your immune system, contribute to insomnia and cause mood swings, among other potential problems.”1

For stress relief, we recommend blending rosemary essential oil with eucalyptus, lavender and a citrus of your choice.

3. Using Rosemary Oil for Pain Relief

Achy joints? Sore muscles? Rosemary oil might do the trick!

Rosemary oil can be used for both pain relief and to reduce joint inflammation. This is because it has been demonstrated to “possesses anti-inflammatory and peripheral antinociceptive activity.”2

Additional studies have shown that rosemary, when combined with accupressure was able to help patients see a “30% reduction in pain” while those “who received only acupressure had a 15% reduction.” A study done on animals showed that rosemary essential oil was “slightly more effective for pain than acetaminophen,”1 the active component in Tylenol.

Honestly, rosemary oil is probably most effective for pain relief when mixed with a carrier oil like jojoba or coconut oil and applied via massage, but we recognize on-demand massages are more of a dream than an every day possibility!

So for pain relief, we recommend combining topical application with the use of a diffuser. Mix it with a carrier oil or a neutral lotion and place a little on the spot that’s bothering you and rub it in.

4. Boost Your Immune System and Fight Off Colds

As we’ll discuss later, rosemary essential oil is packed with different phytochemicals that provide a swath of different benefits and properties. Two of these properties combine to make rosemary oil a potent immune system booster. Those properties are it’s natural antibacterial and anti-fungal qualities. It also works as a decongestant for your nose and sinus. So when cold and flu season starts, it might not be a bad idea to diffuse some rosemary oil in your home.

While rosemary works great on its own for boosting the immune system, lavender oil is always a great addition too! If you want to try a blend with more flavors, try adding eucalyptus, clove or cinnamon essential oils.

5. Increase Circulation

If you ever feel like your fingers or toes are cold or tingly even when the surrounding temperature is average or warm, diffusing rosemary essential oil might be a cost-effective solution. However, if you have a serious condition, we recommend visiting a healthcare professional.

The improved circulation from rosemary oil might be due to the fact that it can expand “your blood vessels, thereby warming your blood so that it reaches your fingers and toes more easily.”1

For improving your circulation, we recommend combining topical application with the use of a diffuser, similar to when using rosemary oil for pain relief. Add the rosemary to a carrier oil and massage into the spots that are experiencing any coldness or numbness.

6. Natural Bug Repellent

While bugs can be quite annoying, no one feels good about inhaling those chemical-based aerosol bug repellents. Diffusing rosemary essential oil might be an easy solution!

According to the studies collected by Healthline, a rosemary oil-based pesticide was able to reduce “the population of two-spotted spider mites by 52% without harming the” greenhouse tomato plants. It can also work to repel ticks and mosquitos. In a test, a “dilution of 12.5% rosemary oil repelled 100% of the mosquitoes for 90 minutes.”1

That sounds pretty effective to us!

If you really want to keep those mosquitoes away, we suggest trying a blend with citronella essential oil.

7. All Natural Air Freshener

If you enjoy the herby aroma of rosemary essential oil, use it as an air freshener or deodorizer! As you’ve seen from the wide range of benefits, there are plenty of things you can do with rosemary oil and one bottle goes a long way!

For the best benefits, we always recommend using an essential oil made from 100% pure, natural ingredients.
