The tropical and subtropical regions of Asia, Africa and the Caribbean are home to the bitter melon, a long, warty green fruit of the gourd family. Also known by the names bitter gourd and bitter squash, this fruit is infamous for its bitter flavor. In spite of this, it is commonly used in a variety of culinary dishes, particularly in Okinawa, where it is known as ‘goya’ and treated as a local delicacy. It is also used to make several beverages, including a soft drink in japan, some types of Asian beer, and an herbal tea. Apart from its culinary uses, bitter melon has also been applied as an herbal medicine. It is most commonly used to support immune system function, digestion, and to regulate blood sugar levels.
