This Herb Is a Super Source of Apigenin, the Anti-Inflammatory Plant Compound Linked to Brain Health and Better Sleep

But aside from rosemary’s delicious flavor, it’s also an herb rich in health perks: It's been shown to help boost your immunity, cognitive health, memory, and focus, as well as your sleep. Many of the above—particularly the latter—is largely due to rosemary's rich apigenin content.

What is apigenin?

“Apigenin is a form of flavonoid—a type of plant compound—which is often found in many herbs,” says registered dietitian Trista Best, MPH, RD, LD. “Flavonoids are phytochemicals, which are chemical compounds produced by plants. Once consumed, phytochemicals are able to provide protection against illness as well as many other health benefits."

According to Best, rosemary is among the richest food source of apigenin. When you consume foods with rosemary, its high apigenin content is able to provide antioxidant-like benefits: Think fighting free-radicals and inflammation in the body, which helps stave off chronic illness, supports your immune system, and boosts your mood. "Other top sources of apigenin include oregano, parsley, celery, artichokes, and chamomile," Best adds. "The great news is that all of these foods taste delicious with rosemary, so you can easily double or triple your apigenin intake by pairing rosemary with another one of these all-star ingredients when cooking."

The health benefits of apigenin

While more research is needed to fully explain the connection between apigenin content and improvements in health and wellness, emerging research shows high potential. “The nutrition science world is quickly learning more regarding the impact apigenin may have on chronic disease and health overall,” says Best.

There are several studies, conducted on both animals and humans, which show promising results regarding the link between apigenin content and improved brain health and cognitive functioning. “Rosemary has been shown to help protect brain cells from damage and death, thereby improving brain health,” says Best. Even its aroma can boost alertness, focus, and memory, for better productivity and working skills, as shown in recent research. “Rosemary is a known natural cognitive stimulant, meaning it can help to enhance alertness and improve your mood.”

Lastly, anti-cancer benefits may also make the list of apigenin benefits, with the help of research, in time. “The impact of apigenin on cellular health has been shown to help slow and reverse damage, which may lower your risk of chronic diseases, like cancer and type 2 diabetes,” says adds. Apigenin may also play a role in slowing and preventing tumor growth at a cellular level, as shown in a 2017 study.

Rosemary’s apigenin content may also help you sleep better

“Some studies have shown that rosemary may have a secondary side effect of improving sleep, which this is due primarily to the impact rosemary has on anxiety and stress,” says Best.

According to Best, new research suggests an association between apigenin content and improved relaxation and wellbeing, which may signify that apigenin has anti-stress and other holistic, therapeutic benefits that work to improve sleep quality and duration. “Rosemary can improve stress by dampening the body's production of cortisol, the stress hormone, as well as potentially—though mildly—slowing your heart rate” says Best. “These two impacts can result in better sleep, though more research is still needed to validate these findings."
