In addition to reversing inflammation and stopping the growth of cancer cells, research has found that rosemary essential oil is also very effective in many other areas.
1. Rosemary Oil Benefits Hair Growth
When applied to the scalp, rosemary essential oil helps stimulate hair growth. Many people also claim that it can prevent baldness, slow down graying and can be used to treat dandruff and dry scalp. After trying a lotion for the hair that he patented, Francesc Casadó Galcerá found a mixture of hops, rosemary and swertia and found some quite remarkable results:
- A 22.4% increase in new hair growth.
- An increase in “rapid” hair growth.
- An increase in microcirculation of the scalp, which promotes healing.
- An improvement in the ability of hair to resist traction.
- A decrease in hair loss after shampooing.
2. Rosemary Improves Memory
“There’s rosemary, that’s for remembrance, pray you love, remember.”
~ Ophelia (Shakespeare’s “Hamlet”)
Used by Greek scholars to improve their memory by taking exams, the capacity for mental strengthening of rosemary has been known for thousands of years. The International Journal of Neuroscience published a study that highlights this phenomenon.
In assessing how the cognitive performance of 144 participants was affected by aromatherapy withoil, aromatherapy with lavender oil and controls from the University of Northumbria, the Newcastle researchers discovered that,
- Probably due to its significant calming effect, “lavender produced a significant decrement in performance of working memory, and impaired reaction times for both memory and attention based tasks.”
- “Rosemary produced a significant enhancement of performance for overall quality of memory and secondary memory factors.”
- Rosemary helped people become more alert.
- Lavender and rosemary helped produced a feeling of “contentment” in the volunteers.

3. Liver Detoxification and Gallbladder Function
Traditionally used for its ability to help with gastrointestinal discomfort, rosemary is also a fantastic detoxifier. Studies have been conducted in India discovering how rosemary supplementation greatly improves your body’s bile flow (which is essential for fat metabolism and detoxification) and reduces liver enzymes in plasma (which has been linked to type II diabetes).
Essentially, by helping to improve the performance of the bile-producing gallbladder (in addition to balancing the microflora in the intestine) proper peristaltic activity is promoted, which increases the absorption of nutrients and helps reverse / prevent toxic overload.
4. Rosemary Lowers Cortisol
A study was conducted out of Meikai University, School of Dentistry in Japan that interestingly evaluated how 5 minutes of lavender and rosemary aromatherapy affected the salivary cortisol levels (the “stress” hormone) of 22 healthy volunteers.
Upon observing that both essential oils enhance free radical scavenging activity, they also discovered that both greatly reduced cortisol levels, which protects the body from chronic disease due to oxidative stress.
