One study using curry leaf extract on rats showed a significant reduction in blood sugar levels and increased antioxidant effect after treatment.

5. Cholesterol Management

Curry leaves contain compounds that may help manage cholesterol levels by reducing the synthesis of LDL cholesterol and promoting the production of good HDL cholesterol. In a study conducted on animals, curry leaf extract treatment resulted in a significant decrease in cholesterol.

Here are some common ways to use curry leaf in cooking:

1. Tempering: In Indian cuisine, curry leaves are often used in a technique called “tempering” or “tadka.” To temper with curry leaves, heat oil or ghee in a pan, and then add mustard seeds, cumin seeds or other whole spices. Once the seeds start to crackle, add curry leaves, and fry them briefly until they release their aroma. Then add this tempered mixture to curries, dals, soups or rice dishes to enhance the flavor of these dishes.
2. Chutneys and dips: Curry leaves can be added to chutneys, dips or sauces for a unique flavor. Blend fresh curry leaves with other ingredients, like coconut, mint, cilantro, tamarind or yogurt to create a flavorful dip for snacks or main dishes.
3. Rice dishes: Curry leaves can be used to flavor various rice dishes, such as lemon rice, coconut rice or pulao. The leaves can be added to rice during the tempering process or stirred directly into cooked rice along with other spices and herbs.
4. Curries and stews: Adding curry leaves to curries — such as Thai green curry, coconut curried chicken or Thai curry kelp noodles— stews or other slow-cooked dishes infuses a complex flavor. You can add the leaves during the tempering process or stir them in while the dish is simmering.
5. Dry spice blends: Dry roasting curry leaves and grinding them with other spices will create a unique spice blend, like curry powder or sambar powder. You can use this blend to season a variety of dishes, from curries to stir-fries.
6. Marinades: Combine fresh or dried curry leaves with yogurt, lemon juice and other spices to create a flavorful marinade for meats, fish or vegetables.

When using curry leaves, it’s important to remember that they have a strong flavor, so a little goes a long way. Fresh curry leaves are generally preferred for their more robust flavor, but dried leaves can also be used in a pinch.

Store fresh curry leaf in an airtight container in the refrigerator for up to two weeks, or freeze for longer storage. Dried curry leaves should be stored in a cool, dark place in an airtight container.

Risks and Side Effects

​​Curry leaves are generally considered safe for consumption when used as a culinary ingredient in moderate amounts. However, some individuals may experience certain risks or side effects associated with consuming curry leaf.

Although it’s rare, some people may have an allergy or sensitivity to curry leaves, which could result in symptoms like itching, swelling or difficulty breathing. If you suspect an allergy to curry leaves, it’s essential to avoid consuming them and consult a health care professional.

Curry leaves may interact with certain medications, particularly those used to manage diabetes, as they may have blood sugar-lowering effects. If you are taking medication for diabetes or any other condition, be sure to consult with a health care professional before consuming curry leaves in large quantities.

The curry leaf plant has been found to contain trace amounts of a toxic alkaloid called girinimbine. However, the levels of this compound in curry leaves are typically very low, and consumption in moderate amounts is not considered harmful.

It’s important to avoid consuming large quantities of curry leaves or using them as a supplement, such as extract forms, without proper guidance from a health care professional.

When used as a culinary ingredient in moderate amounts, curry leaves are generally safe and well-tolerated by most people.
