Provides Antioxidants

Because of its rich supply of antioxidants and bioactive chemicals (including phenolic diterpenes, such as carnosol and caffeoyl derivatives), consuming rosemary can help fight oxidative stress and support the immune system. It’s also known to promote healthy circulation and to defend against inflammation, which can lead to pain.

Another way that rosemary’s antioxidants can be beneficial is due to the ability to promote skin health by fighting free radical damage that leads to signs of aging.

Can Help Lift Your Mood and Boost Alertness

Like some other herbs in the mint family, rosemary’s smell is considered a “cognitive stimulant” and can help make you feel more awake and focused. Some studies have also shown that compounds within rosemary/rosemary oil have neuro-protective effects and the ability to improve memory and cognitive performance by preventing the breakdown of acetylcholine, a chemical in the brain that contributes to concentration and memory retention.

Additionally, the uplifting and energizing aroma of rosemary has been linked to improved moods, reduces drowsiness and reduced stress levels, including due to its ability to decrease release of the “stress hormone” cortisol. This is the reason you’ll find rosemary in some candles, home sprays, aromatherapy oils, etc.

May Help Stimulate Hair Growth

Rosemary (most often in the form of rosemary oil) is found in some hair care products intended to help promote hair growth and a healthy scalp, since it can fight against dandruff and skin irritation that causes dryness. It may also decrease the effects of testosterone on hair follicles, which can lead to hair loss and balding/thinning.

Helps Relieve Indigestion

This herb, whether cooked with or steeped in herbal tea, has long been a natural remedy for digestive issues, including loss of appetite, heart burn/acid reflux, gas, bloating and abdominal pains. It seems capable of stimulating the release of digestive fluids including bile, which assists in digestion and can support normal nutrient absorption.

Has Natural Antimicrobial Properties

Within rosemary there are compounds that can help defend against proliferation of certain types of harmful bacteria, including those that contribute to infections. Rosemary extracts are even used as food preservatives in some cases because they can help stop bacteria from growing.

The smell of rosemary also acts as a natural bug repellent and may help prevent certain insect bites, including from ticks and other bugs that can spread illnesses and viruses.

Can Help Promote Metabolic Health

Rosemary has been associated with metabolic benefits including helping to treat high blood sugar and poor insulin sensitivity. While it likely won’t be enough to prevent diabetes on its own, it’s recommended for people who wish to improve their high blood sugar levels.
