The Magic of Rosemary
If your kitchen had a signature scent, there’s a good chance it would be rosemary. This bold, piney herb doesn’t just smell amazing, it has a history as rich as its aroma and more uses than you might imagine. Let’s take a fresh look at this timeless favorite!
A Little History, A Lot of Legend
Rosemary has been around for centuries, and not just on roasted potatoes. Native to the Mediterranean region, the Roman armies brought rosemary (Rosmarinus officinalis) to Britain. It was considered sacred by the ancient Greeks and Romans. Students in ancient Greece would tuck sprigs behind their ears to help boost memory during exams.
In ancient times, rosemary symbolized remembrance and fidelity. It was often also used in weddings and funerals.1
Health Benefits
While rosemary has earned its culinary stripes, it’s also packed with benefits that go beyond the plate.
- Brain Booster: Oxidative damage is one of the factors that contribute to aging. Neuron dysfunction in aging-related illnesses, such as Alzheimer’s disease, is thought to be primarily caused by oxidative stress. Free radicals cause oxidative stress and aging. Aging and related disorders arise when endogenous antioxidants are unable to counteract free radical damage to cells and biological molecules. Plant extracts containing antioxidants could be very beneficial. Rosemary extract administered for 90 days appeared to improve learning and memory. The scent of rosemary oil has even been demonstrated to boost exam performance in students, partially by lowering free radicals and cortisol levels.2
- Pain Control: Rosemary contains compounds, such as eugenol, rosmanol, and heperidine that work alongside medications to control pain. These compounds target some of the same receptors that opioids and NSAIDs target. Using rosemary essential oil can provide synergistic effects to pain medications, which allows for lower doses of these medications and fewer side effects.3
- Stress Relief: The anti-anxiety effect of rosemary has been attributed to its antioxidant and anti-inflammatory effects. The plant contains many phytocompounds that act throughout the central nervous system. One of these compounds, called apigenin, can increase the effect of the GABA neurotransmitter. Benzodiazepines, common medications used to treat anxiety, also target GABA receptors. Fortunately, the plant compounds do not cause dependence, whereas benzodiazepines can.3
- Infection Prevention: Bacteria can join together and form biofilms, which offer them protection against the immune system and antibiotics, so they can more easily cause infection. Extracts from rosemary have shown the ability to prevent microbes from sticking together, reducing their ability to form these biofilms. Rosemary may be particularly useful for oral hygiene. Microorganisms that cause oral infections commonly form biofilms that adhere to surfaces, such as teeth, oral mucosa, and orthodontic appliances. Therefore, the addition of rosemary to toothpaste and other oral hygiene products could be beneficial.3
- Hair Growth: Alopecia can be a chronic condition resulting in hair loss. It can stem from a variety of causes, including genetics, hormonal changes, medical conditions, medications, and even stress. Rosemary oil has been proven to be effective for alopecia by improving the vascularity and the circulation of blood, in addition to enhancing the regeneration of the hair follicles. In some cases, it has been as effective as prescription medications, without the side effects.4
