Rosemary, also known as Rosmarini folium in Latin and Rosmarinus officinalis botanically, is a common herb that is used for both culinary and medicinal purposes. This fragrant, perennial herb bears small, pointed leaves that resemble pine needles, and once dried, these leaves can be prepared as an extract for oral ingestion. Research suggests that ingesting rosemary as a supplement could impart over a dozen health benefits including pain relief, neuroprotection, stress relief, and improved cardiovascular health.
The beneficial compounds in rosemary are water-soluble, so they absorb into your body quickly and efficiently.
In addition to consuming this herb in supplements, you can also consume dried rosemary needles.
Rosemary is not recognised as an essential nutrient, so there is no nutrient reference value (NRV) for this herb. In clinical studies, doses of up to 6mg of dried rosemary per day have been used.
The only common way to consume rosemary in food is to eat rosemary-infused bread. Unless you intend to eat rosemary bread every day, however, you’ll find it hard to get enough of this beneficial substance from the foods you eat.
Rosemary has been used since time immemorial as a herbal healing tool, which has led modern scientists to take a closer look at the potential medical benefits of this common culinary ingredient. So far, research has indicated that even inhaling rosemary essential oil is enough to provide beneficial effects, and it appears that orally ingesting this herb provides even stronger benefits. While scientists still aren’t sure how rosemary exerts all of its noted beneficial effects, a few different applications of this natural healing substance have been proposed.
Based on the available evidence, rosemary appears to be useful to people of all ages and backgrounds. This natural herbal supplement may be even more useful for individuals who are battling stress or having trouble concentrating in their day-to-day lives. Additionally, if you suffer from hair loss, you may want to try rosemary instead of conventional treatments.
Like most herbal supplements, it may take a few days or weeks of repeated supplementation to notice the beneficial effects of Rosmarinus officinalis, but many people who use this herb report immediate benefits.

A 2020 study indicates that rosemary may be useful as a treatment for allergies. This study found that rosemary extract improved the action of immune mast cells, which are involved in allergic responses. Also in 2020, a scientific review was released that summarises the results of recent enquiries into the potential neurological benefits of rosemary. The authors found that rosemary shows genuine potential as a treatment for anxiety, memory impairment, inflammation, and pain.
