What Is Neem?

The neem tree (Azadirachta indica) is commonly used in India and Africa for everything from infections and fevers to teeth brushing. Indian Ayurveda and traditional medicine widely use plants like neem (aka Indian lilac), turmeric, and others in their arsenal.

More recently, there have been hundreds of studies on neem for a wide range of issues. The leaves, flowers, seeds, roots, neem seed oil, and bark were traditionally used. Much of the current research and uses are for neem seed extract and leaf though.

Scientists have identified over 140 constituents and active compounds in neem. Nimbin is one of the main active components behind neem’s medicinal properties.

Health Benefits of Neem

Neem has an impressively long list of purported health benefits. And a lot of the traditional uses are now being supported with current research. Many of the studies are done in test tubes and on animals, so the results aren’t always conclusive.

Not much research has been done on neem’s direct effect on humans. However, neem does have an extensive history (thousands of years!) of use in humans in certain cultures. The benefits below include both traditional use and ones backed by modern research. As always this isn’t medical advice and I encourage you to do your own research.

Neem Benefits for Oral Health

One of the most popular ways to use neem is for oral health. You’ll find it widely used in Ayurvedic toothpaste, mouthwash, and oral hygiene. It’s even in the whitening toothpaste from Wellnesse. Neem products have a lot of benefits for the mouth and gums.

They’re antimicrobial to fight harmful strains of bacteria in the mouth. The anti-inflammatory properties also help soothe gingivitis and irritated gum tissue. While a healthy, whole foods diet is the best first line of defense when it comes to a healthy mouth, neem can also be a helpful ally.

A 2021 study found that neem helped with several bacteria found in tooth decay. A 2020 meta-analysis reported on neem’s positive track record against mouth cancer. Multiple studies show it helps fight drug-resistant bacteria and tricky biofilms in the mouth.

Several studies have shown promising results with neem’s ability to control plaque and reduce gum inflammation. However, a 2017 review found that many of these mouthwash studies were flawed or biased. Because neem is such a potent antimicrobial and anti-inflammatory, it’s still a welcome ingredient in my oral care routine.

Neem, Dandruff, and Yeast

Ayurvedic medicines, like neem, are traditionally used to address scalp issues. The main culprit behind dandruff is an overgrowth of the yeast, Malassezia. Neem is antimicrobial, anti-inflammatory, and has anti-fungal properties that help fight dandruff.

Diabetes and Metabolic Syndrome

A 2021 review looked at neem’s role in metabolic syndrome. The researchers found neem’s antioxidants play an important role. They also report on neem’s ability to lower blood sugar levels, help with weight, and lower high blood pressure.

A 2019 trial looked at neem leaf and neem twig extract for metabolic syndrome. The subjects had better blood sugar levels, less insulin resistance, and better hemoglobin A1c levels over time. They also saw improved endothelial function and less inflammation and oxidative stress.

In a rat study, neem leaf extract had some surprising effects. It improved weight gain and helped regenerate beta cells. We rely on beta cells to make insulin, so their health is critical to diabetes prevention.

While neem leaf can help with metabolic syndrome, the bark plays a role in wellness too. A 2009 review found neem bark extract helped with ulcers and protected the gastrointestinal system.

The Bottom Line on Benefits of Neem

Neem has a whole lot to offer, but like any supplement or plant, it should be used wisely. Do some research to see if it could be a good fit for your personal situation. I’ve found it really helpful for my own family when it comes to things like warding off pests!
