#CitrusHystrix

For centuries, the aromatic leaves and knobbly fruits of the kaffir lime—known in Thai as makrut—have graced Thai kitchens, ritual spaces, and medicine cabinets. Its distinctive fragrance is instantly recognisable in tom yum soup and green curry, yet beyond its culinary appeal lies a trove of traditional healing wisdom. Today, scientists are delving deep into this humble plant’s chemistry, revealing how ancient practices may be supported—and sometimes challenged—by modern research.

In every Thai kitchen, the knobby green fruit known as makrut lime (Citrus hystrix DC.) is more than a culinary staple – it’s an emblem of culture, tradition, and natural healing. From northern rural hamlets to Bangkok’s bustling wet markets, the aroma of makrut lime leaves and the zingy freshness of its peel invoke centuries of folk medicine, family wisdom, and scientific intrigue. As modern research shines new light on this beloved herbal staple, makrut lime’s remarkable journey from ancient remedy to subject of laboratory scrutiny underscores the vibrant intersection of indigenous knowledge and contemporary health science.
