Bitter gourd, also called bitter melon or karela, is a tropical climbing vine of the Cucurbitaceae family whose cucumber-like fruits are prized across Asia, the Caribbean, and parts of Africa for their intensely bitter flavor and reputed medicinal properties.
History & Origins
Bitter gourd has been cultivated for millennia, with references in Chinese herbal texts dating to the 14th century and earlier Ayurvedic practice in the Indian subcontinent. It was carried to the Americas via the African and Asian diasporas, where it naturalized in the Caribbean and Brazil and became a fixture of Creole, Surinamese, and West Indian cookery. Today China, India, the Philippines, and Vietnam are the leading producers, and the fruit is grown in tropical and subtropical regions worldwide.
