Curry leaves are a staple in Indian, Sri Lankan, and Southeast Asian cooking. Although originating from the Indian subcontinent, curry leaves are famous worldwide for their distinctive aroma and earthy, slightly citrusy flavour. Beyond their remarkable flavour, curry leaves are also a rich source of nutrients, antioxidants, and phytonutrients that offer numerous benefits for overall well-being. From aiding digestion to promoting hair health and even possessing potential medicinal properties, this article talks about the remarkable health benefits curry leaves offer.
Benefits of Curry Leaves
Given below are the various benefits of curry leaves that make them a promising addition to any diet.
Anti-cancer Benefits
Curry leaves exhibit impressive potential in cancer prevention due to the various beneficial compounds they contain. An alkaloid named girinimbine found in curry leaves has shown the ability to induce cell death in colon cancer cells, marking a significant breakthrough. Moreover, curry leaves are rich in antioxidants, including quercetin, catechin, rutin, and gallic acid, which, along with girinimbine, possess anti-cancer properties.
The application of curry leaf extract has demonstrated anti-cancer properties by effectively inhibiting the proliferation of an aggressive strain of breast cancer. It not only reduced the viability of two distinct breast cancer cell types but also induced cell death in these malignant cells. Additionally, studies also indicate the efficacy of curry leaf extract in curbing cervical cancer cells.
Oral administration of curry leaf extract effectively lowers tumour growth and limits the spread of breast cancer cells to the lungs. While the evidence is promising, further research is necessary to gain a comprehensive understanding of curry leaves’ cancer-fighting potential.
Protects From Heart Diseases
High levels of triglycerides and cholesterol are common risk factors for heart disease. Curry leaf extract plays a vital role in reducing excessive triglycerides and cholesterol levels. In a 2-week trial involving obese individuals, oral supplementation with 136 mg of curry leaf extract per day (equivalent to 300 mg per kg of body weight) led to a significant reduction in cholesterol and triglyceride levels. This reduction is due to the presence of the alkaloid mahanimbine within curry leaves.
Mahanimbine acts as a potent agent that hinders the development of diet-related issues known to increase the risk of heart disease, including elevated blood lipids, fat accumulation, inflammation, and oxidative stress. Although these findings are promising, continued research is necessary to substantiate these claims further.
Protects From Oxidative Damage
Curry leaves are a rich source of defensive plant-based compounds, including glycosides, phenolic compounds, and alkaloids. Comprehensive research shows a spectrum of beneficial chemicals within curry leaves, such as linalool, caryophyllene, myrcene, mahanimbine, alpha-terpinene, and murrayanol. Many of these compounds act as antioxidants, effectively combating potentially harmful substances known as free radicals and thereby reducing oxidative stress, a precursor to chronic diseases.
Oral administration of curry leaf extract has demonstrated a protective effect against stomach damage induced by medication and a reduction in oxidative stress markers. These findings underline the potential of curry leaf extract in safeguarding the body against oxidative stress-induced harm to vital organs, including the heart, brain, kidneys, and the neurological system.
Combats Neurological Problems
Emerging evidence suggests that curry leaves play a significant role in safeguarding neurological health. Potential compounds within curry leaves that could offer protection against neurological problems, including Alzheimer’s disease.
Curry leaf extracts increase levels of brain-protective antioxidants, including superoxide dismutase (SOD), glutathione reductase (GRD), and glutathione peroxidase (GPx). Furthermore, curry leaf extract helps reduce oxidative damage to brain cells and lowers the activity of enzymes responsible for the progression of Alzheimer’s disease.
Dermatological Benefits
Curry leaves offer a range of remarkable benefits when applied topically. They possess valuable antimicrobial properties, making them a favoured ingredient in herbal soaps. Furthermore, these leaves impart a refreshing, cooling sensation when used in summertime deodorants, leaving one feeling rejuvenated and fragrant. In addition to their cooling effect, curry leaves also boast potent antibacterial, antifungal, and antiseptic qualities, making them a standard inclusion in various facial creams and body lotions.
Creating a paste from curd, turmeric, and curry leaves can alleviate skin rash and irritations. Moreover, a blend of curry leaves and coconut oil can be applied to the hair to improve its quality, while a mixture of curry leaves and lemon juice can strengthen hair roots. Curry leaves contain antioxidants, such as beta-carotene, which may help maintain the hair’s natural colour and slow down the greying process.
Summary
Curry leaves offer a multitude of health and dermatological benefits. They have shown promise in cancer prevention due to compounds like girinimbine and antioxidants like quercetin, catechin, rutin, and gallic acid. Notably, curry leaf extract has demonstrated anti-cancer properties against breast and cervical cancer cells, as well as inhibiting tumour growth in breast cancer. In addition to their cancer-fighting potential, curry leaves can aid in heart disease prevention by reducing cholesterol and triglyceride levels, thanks to the alkaloid mahanimbine. These leaves are also rich in antioxidants, protecting against oxidative stress, which is a precursor to chronic diseases. Emerging evidence suggests that curry leaves may have a protective role in neurological health, potentially guarding against conditions like Alzheimer’s. Curry leaves’ antimicrobial, cooling, and antibacterial properties make them a valuable ingredient in herbal soaps and skincare products. Topical applications, such as paste with curd and turmeric or mixtures with coconut oil and lemon juice, can alleviate skin issues and strengthen hair. While the evidence is promising, further research is necessary to understand the extent of curry leaves’ health benefits fully.
