About
Curry leaves are the aromatic foliage of Murraya koenigii (L.) Spreng (Family: Rutaceae), a tropical and subtropical plant native to the Indian subcontinent; they are slightly bitter, pungent, and weakly acidic, and are used extensively as a culinary herb and spice in South Asian, Southeast Asian, and Sri Lankan cuisines. They hold a centuries-long role in Indian Ayurvedic medicine (known as 'krishnanimba') and are valued both for their distinctive flavour and their broad spectrum of bioactive phytochemicals including carbazole alkaloids, terpenoids, and flavonoids.
Safety summary
Curry leaves are generally regarded as safe at culinary doses; a rat feeding study found no adverse haematological or serum-biochemical effects at doses equivalent to normal human dietary intake. Multiple peer-reviewed reviews document antioxidant, hepatoprotective, anti-inflammatory, nephroprotective, and antimicrobial properties with no evidence of intrinsic toxicity at food-use levels. Their documented hypoglycaemic and antihyperglycaemic activity may potentiate antidiabetic medications, and high-dose supplemental extract use during pregnancy lacks adequate clinical safety data.
Regulatory landscape
| Jurisdiction | Status | Note |
|---|---|---|
| EFSA (European Food Safety Authority) (European Union) | Approved | Curry leaves are not listed in the EU Union List of Authorised Novel Foods (Commission Implementing Regulation (EU) 2017/2470), indicating they are not classified as a novel food and have a recognised history of traditional consumption. No E-number is assigned as curry leaves are not used as a functional food additive. No specific EFSA safety opinion has been issued. Regulated as a traditional herb/spice under general EU food law (Regulation (EC) No 178/2002).source |
| FSSAI (Food Safety and Standards Authority of India) (India) | Approved | Regulated as a permitted spice and condiment under the Food Safety and Standards (Food Products Standards and Food Additives) Regulations, 2011, Chapter 2.9 (Salt, Spices, Condiments and Related Products).
