9 Benefits and Uses of Curry Leaves
Curry leaves are the foliage of the curry tree (Murraya koenigii). This tree is native to India, and its leaves are used for both medicinal and culinary applications. They’re highly aromatic and have a unique flavor with notes of citrus.
Curry leaves are not the same as curry powder, though they’re often added to this popular spice mixture and popularly used in cooking to add flavor to dishes, such as curries, rice dishes, and dals.
Aside from being a versatile culinary herb, they offer an abundance of health benefits due to the powerful plant compounds they contain.
Here are 9 impressive benefits and uses of curry leaves.
Curry leaves are rich in protective plant substances, such as alkaloids, glycosides, and phenolic compounds, that give this fragrant herb potent health benefits.
Research has shown that curry leaves contain many compounds, including linalool, alpha-terpinene, myrcene, mahanimbine, caryophyllene, murrayanol, and alpha-pinene (2Trusted Source, 3Trusted Source, 4Trusted Source).
Many of these compounds function as antioxidants in your body. Antioxidants play an essential role in keeping your body healthy and free from disease.
They scavenge potentially harmful compounds known as free radicals and suppress oxidative stress, a condition that’s associated with chronic disease development (4Trusted Source).
Curry leaf extract has been shown to provide potent antioxidant effects in several studies.
For example, a study in rats demonstrated that oral treatment with antioxidant-rich curry leaf extract protected against medication-induced stomach damage and reduced markers of oxidative stress, compared with a placebo group (5Trusted Source).
Other animal studies have shown that curry leaf extract may help protect against induced oxidative damage of the nervous system, heart, brain, and kidneys (6Trusted Source, 7Trusted Source, 8Trusted Source, 9Trusted Source).
Keep in mind that human research on the antioxidant effects of curry leaves is lacking. Nevertheless, there’s no doubt that curry leaves are packed with plant compounds that may help promote overall health by providing powerful antioxidant protection.
Curry leaves are packed with antioxidants that may protect your body by reducing oxidative stress and scavenging free radicals.
Risk factors like high cholesterol and triglyceride levels may increase your risk of developing heart disease. Adding curry leaves to your diet may help reduce some of these risk factors.
Research shows that consuming curry leaves may benefit heart health in several ways. For example, animal studies have found that curry leaf extract may help reduce high cholesterol and triglyceride levels.
A 2-week study in rats with high-fat-diet-induced obesity showed that oral treatment with 136 mg of curry leaf extract per pound (300 mg per kg) of body weight per day significantly lowered cholesterol and triglyceride levels.
These results were correlated with the high amount of an alkaloid called mahanimbine in the leaves (10Trusted Source)
In another 12-week study in mice on a high fat diet, mahanimbine prevented diet-induced complications, such as high blood lipids, fat accumulation, inflammation, and oxidative stress — all of which may increase the risk of heart disease (11Trusted Source).
Other animal studies have also shown that curry leaf extract reduces cholesterol levels (12Trusted Source).
Although these findings are promising, research in humans is lacking. For this reason, more studies are needed to confirm this potential benefit of curry leaves.
Consuming curry leaves may benefit heart health by reducing heart disease risk factors, such as high cholesterol and triglyceride levels. However, more research is needed.
Some research has shown that curry leaves may help protect the health of your nervous system, including your brain.
Studies have demonstrated that curry leaves contain substances that may help protect against neurodegenerative conditions like Alzheimer’s disease.
A study in mice found that oral treatment with high doses of curry leaf extract improved levels of brain-protecting antioxidants, including glutathione peroxidase (GPx), glutathione reductase (GRD), and superoxide dismutase (SOD), in brain cells (8Trusted Source).
The extract also reduced the amount of oxidative damage in brain cells, as well as enzymes associated with Alzheimer’s disease progression (8Trusted Source).
Another study showed that oral treatment with curry leaf extract for 15 days improved memory scores in both young and aged mice with induced dementia (13Trusted Source).
Keep in mind that human research in this area is lacking, and more studies are needed before strong conclusions can be made.
Some research in animals suggests that curry leaf extract may protect against neurodegenerative diseases. However, more research is needed.
Curry leaves contain compounds that have significant anticancer effects.
A test-tube study involving three curry extract samples from curry leaves grown in different locations in Malaysia found that they all exhibited powerful anticancer effects and inhibited the growth of an aggressive type of breast cancer (14Trusted Source).
Another test-tube study found that curry leaf extract altered the growth of two types of breast cancer cells, as well as decreased cell viability. The extract also induced breast cancer cell death (15Trusted Source).
Additionally, curry leaf extract has been shown to be toxic to cervical cancer cells in test-tube research (16Trusted Source).
What’s more, test-tube studies indicate that an alkaloid compound in curry leaves called girinimbine induces colon cancer cell death (18Trusted Source).
In addition to girinimbine, researchers attribute these powerful anticancer effects to the antioxidants in curry leaves, including quercetin, catechin, rutin, and gallic acid (14Trusted Source).
While it’s clear that curry leaves contain compounds that have the potential to fight certain cancer cells, research on its effectiveness in humans is needed.
Test-tube and animal research suggests that curry leaves may have powerful anticancer properties.
In addition to the potential benefits listed above, curry leaves may benefit health in the following ways:
- Beneficial for blood sugar control. Animal research has demonstrated that curry leaf extract may help reduce high blood sugar levels and protect against symptoms related to diabetes, including nerve pain and kidney damage (19Trusted Source).
- May have pain-relieving properties. Research in rodents has shown that oral administration of curry extract significantly reduces induced pain (20Trusted Source).
- Has anti-inflammatory effects. Curry leaves contain a wide array of anti-inflammatory compounds, and animal research has shown that curry leaf extract can help reduce inflammation-related genes and proteins (17Trusted Source).
- Offers antibacterial properties. A test-tube study found that curry leaf extract inhibited the growth of potentially harmful bacteria, including Corynebacterium tuberculosis and Streptococcus pyogenes (2Trusted Source).
It should be noted that these benefits have been demonstrated in test-tube or animal research. Future research in humans is needed to substantiate these potential benefits.
Curry leaves may offer antibacterial, antidiabetic, pain-relieving, and anti-inflammatory effects, though more research is needed.
Curry leaves have been used since ancient times in traditional Indian cuisine. Their unique taste is often described as carrying subtle notes of citrus with a hint of nuttiness.
The leaves are commonly added to dishes to bring about a robust, rich flavor and popularly used in meat dishes, curries, and other traditional Indian recipes.
