Bitter melon (Momordica charantia) is a tendril-bearing vine in the Cucurbitaceae family native to tropical Asia and widely cultivated in other warm regions. It has deeply lobed leaves, yellow flowers, and distinctive warty fruit that turns orange as it ripens. The fruit is the part most often used, although the leaves also appear in some traditional preparations.

Across Asian, Caribbean, and tropical folk traditions, bitter melon is valued both as a food and as an intensely bitter plant in household herbal use. It is commonly cooked as a vegetable, steeped as a tea, or included in short-term bitter preparations where its cooling, drying, and strongly bitter qualities are emphasized.
