We usually add it as a spice in various dishes or possibly as a supplement to tea, but rosemary is a very powerful plant that can help improve physical and mental health in many ways.

Numerous studies have shown that rosemary is not just a spice, but also a superfood that has numerous medicinal properties, writes "Mind Body Green".

Throughout history, people have used rosemary to enhance memory. Even Shakespeare famously wrote about it in Hamlet.

Even today, rosemary is thought to help improve memory, but some research shows that it has a positive effect on improving mood and reducing stress.

In a 2018 study, laboratory mice exposed to chronic stress were given rosemary extract and found to have antidepressant effects.

Scientists believe that the reason lies in the fact that the plant has anti-inflammatory properties and helps alleviate inflammatory processes in the region of the brain called the hippocampus, but also in the gut. Although there is still research that attempts to connect gut health to brain health, it seems that a good mood, optimism and sharp mind are related to a healthy microbiome.
Rosemary contains a compound that binds to cannabinoid receptors. Although we don't yet know how or why, it appears that this binding to the receptors reduces the impact of the body's stress response.

Although the studies on rosemary and blood sugar to date have been laboratory and animal studies, there are strong indications that rosemary tea has a blood sugar-lowering effect. The effect is due to its so-called insulin-like components (primarily the aforementioned antioxidant compounds rosmarinic and carnosic acid), which means that rosemary helps to facilitate the absorption of glucose into muscle tissue.

Other research suggests that inhaling the essential oils of rosemary and similar herbs may have a positive effect on brain function in older adults, especially those suffering from Alzheimer's.

Drinking rosemary tea has similar effects.
