Eating 10 curry leaves every day can have several health benefits due to the rich nutritional profile of curry leaves. Curry leaves are a staple in Indian cooking and are loaded with vitamins, antioxidants and minerals that can boost health in numerous ways. Here is an overview of the top benefits that may occur from eating 10 curry leaves daily.

May Support Heart Health
Curry leaves contain several nutrients that are great for heart health. Just 10 curry leaves provide over 15% of the recommended daily intake for vitamin A, vitamin B6 and vitamin C (1). Vitamin A and C are powerful antioxidants that can help protect against free radical damage and inflammation, which are major risk factors for heart disease (2, 3). Vitamin B6 helps regulate levels of hom*ocysteine, high levels of which have been associated with increased heart disease risk (4). In one study, rats fed a high-fat diet supplemented with curry leaves for 10 days experienced an improvement in heart function and a reduction in total cholesterol levels, compared to a control group (5). Other studies have found that the antioxidants in curry leaves can reduce cholesterol levels and protect the heart against damage from toxins (6, 7).
May Lower Blood Sugar Levels
Several studies have found that eating curry leaves may help lower blood sugar levels, especially for those with diabetes. In one study, people with diabetes who consumed curry leaves daily experienced significant reductions in blood sugar levels after a meal, compared to a placebo group (8). Research also shows that curry leaves contain an ingredient called mahanimbine, which exhibits anti-diabetic properties in rats with diabetes (9). The fiber in curry leaves may also help slow the absorption of sugar in the bloodstream after meals (10). Eating just 10 curry leaves per day may help keep blood sugar levels in check. More studies are needed to determine optimal dosage for blood sugar control.
May Protect Against Cancer
Test-tube and animal studies demonstrate that curry leaves have powerful antioxidant and anti-inflammatory properties that may help protect against cancer. Curry leaves are rich in compounds like quercetin, gallic acid and flavonoids, which have been shown to inhibit cancer cell growth and reduce tumor formation in animal studies (11, 12). One study in rats found that supplementing the diet with curry leaves for 30 days reduced liver weight by 16% compared to a control group. Liver weight is a marker of liver damage and cancer risk (13). However, more research is needed to determine if eating curry leaves has anti-cancer effects in humans.
May Reduce Anxiety and Stress
Animal studies have found that curry leaf extract may reduce markers of stress and anxiety. In one study, rats fed curry leaf extract experienced less anxiety and improved antioxidant status compared to a control group (14). Curry leaves also contain carbazole alkaloids that exhibit anti-anxiety and antidepressant effects in animal models (15). While human studies are lacking, anecdotal evidence suggests curry leaf tea may lower anxiety levels and promote relaxation. The potential anti-anxiety effects may be due to antioxidants that reduce inflammation and lower levels of cortisol, one of the primary hormones involved in the stress response.
May Promote Hair Growth
Curry leaves are often touted as a natural remedy for stimulating hair growth and reducing hair loss, likely due to their content of beta-carotene and proteins. One study in mice found that oral administration of curry leaf extract for 30 days led to a 27-38% reduction in hair loss, compared to a control group (16). Test-tube studies demonstrate that curry leaf extract strengthens hair follicles and increases proliferation of hair follicle cells, which may promote hair growth (17). Human research is lacking, but applying a hair oil with a curry leaf base or eating curry leaves is unlikely to have any negative effects on hair health.
May Improve Gut Health
Some evidence suggests curry leaves may support gut health in several ways. First, they are high in fiber, providing around 7 grams per 100 grams of leaves (1). Fiber moves slowly through the gut undigested and helps promote the growth of beneficial gut bacteria (18). Test-tube studies also show that curry leaf extract may reduce the growth of certain types of harmful gut bacteria, including Helicobacter pylori, a major cause of stomach ulcers (19, 20). However, human studies are needed before recommendations can be made.
May Reduce Nausea and Vomiting
Traditional medicine practices have long used various parts of the curry leaf plant to treat nausea and vomiting. Some test-tube and animal studies indicate curry leaf extract may have anti-nausea and vomiting properties. One study found that curry leaf extract reduced vomiting in rats by 50-55% compared to a control group (21). Another study showed that ginger and curry leaf powder reduced nausea and vomiting during pregnancy (22). More studies are needed to confirm these effects in humans.
Easy to Add to Your Diet
Including more curry leaves in your diet is easy. You can simply pluck 10 fresh leaves to chew on daily. Curry leaves have a slightly sweet, citrusy flavor. Alternatively, try sprinkling them on top of meals, blending them into smoothies or juices or using curry leaf powder in soups, curries or stews. Dried curry leaves are also available and can be made into tea. Be sure not to confuse curry leaves with bay leaves, as they belong to different (though related) plant species.
May Cause Adverse Effects in Some People
Curry leaves are generally recognized as safe with very few reported side effects. However, some people may be allergic or sensitive to substances in curry leaves. Using curry leaf medicinal amounts greater than dietary intake may not be safe for pregnant women, as it might stimulate the uterus (23). Curry leaves contain oxalates, which can contribute to kidney stone development in susceptible people prone to that condition. But for most people, eating 10 curry leaves per day as part of a balanced diet is likely safe.
Some Drawbacks to Consider
While research shows curry leaves have many benefits, there are some drawbacks to consider:
- Most studies have been conducted in animals or test tubes, with limited human data
- There is little research on appropriate therapeutic dosages for humans
- Potential drug interactions are unknown
- Curry leaves may cause allergic reactions in some
- Overconsumption may contribute to kidney stones in prone individuals
As with any supplement, talk to your healthcare provider before adding curry leaves to your routine, especially if you take any medications or have underlying health conditions.
May Interact with Blood Thinners
Some sources indicate that curry leaves may have blood-thinning effects. Blood thinners work to prevent excessive clotting by reducing the clumping together of platelets. Common blood thinners include warfarin, heparin and clopidogrel. Consuming curry leaves may strengthen the effects of these medications, which could increase the risk of bleeding and bruising. Speak to your healthcare provider before consuming curry leaves if you are taking blood thinners (24).
Allergic Reactions Are Possible
Some people may be allergic to compounds found in curry leaves. Allergy symptoms may include itching, hives, swelling, tingling of the mouth and difficulty breathing. Discontinue use if any hypersensitivity reactions occur and consult a doctor if symptoms are severe. Curry leaves are part of the same plant family as celery, carrots, mugwort and birch pollen, so cross-reactivity is possible in people with known allergies to those foods or substances (25).
Excess Oxalates Could Trigger Kidney Stones
Curry leaves contain soluble oxalate salts, which can accumulate in the kidneys and form kidney stones in susceptible individuals. Those with a history of kidney stones may want to avoid eating large amounts of curry leaves. High oxalate foods like spinach, sweet potatoes, nuts and chocolate may also need to be limited for people prone to kidney stones (26). Stay hydrated and limit oxalate consumption from all sources if you are at risk of developing kidney stones.
Limited Research on Safety During Pregnancy
Due to limited data, curry leaf supplements are not recommended during pregnancy, as they may stimulate the uterus. However, eating a small number of curry leaves as part of a normal diet is likely fine. But check with your healthcare provider first if you are pregnant and wish to consume medicinal amounts or supplements containing curry leaf (27).
Could Cause Low Blood Sugar
Animal and test-tube studies show curry leaves may reduce blood sugar levels, especially in those with diabetes. Eating large amounts could potentially cause abnormally low blood sugar, or hypoglycemia, in some. Monitor blood sugar carefully if taking diabetes medications along with curry leaves (28).
Unknown Effects for Children
There is currently no data on the safety or efficacy of medicinal curry leaf amounts in children. Curry leaf supplements and extracts should be avoided in children until more research confirms appropriate pediatric dosing (29). However, incorporating a small number of curry leaves into a balanced diet is likely fine.
Could Cause Contractions During Pregnancy
According to some animal studies, compounds in curry leaves may stimulate uterus contractions. While the leaves are considered safe when consumed in normal dietary amounts during pregnancy, extracts, supplements or medicinal quantities may trigger premature contractions and should be avoided (30).
May React with Drugs Metabolized by the Liver
Animal data suggests compounds in curry leaves may increase liver enzymes that help metabolize medications. This could decrease the effectiveness of certain drugs broken down by the liver. Drugs using the CYP3A4 enzyme pathway may be particularly affected. More human research is needed, but talk to your doctor if taking any prescription medications along with curry leaves (31).
Could Cause Digestive Upset
Eating too many curry leaves may cause mild digestive upset in some people. Side effects can include diarrhea, cramping and abdominal pain. Start with small amounts and discontinue use if any discomfort occurs (32).
Dosage Has Not Been Established
There are currently no standard dosage guidelines for consuming curry leaves. Most research has looked at extracts providing doses of around 300-400mg per pound (600-800 mg/kg) of body weight in rats. However, human conversions cannot be made until more studies determine appropriate dosing and safety (33). Stick to normal dietary amounts of around 10 leaves per day until more data is available.
