Hebesu
Hebesu or hebezu (平兵衛酢) is a small Japanese citrus fruit.It is green in color, rich in acid and reported to have high amounts of a specific flavonoid which supposedly has anti-cancer properties.[2][3] The fruit is considered a local delicacy of Hyūga, Miyazaki.[4][5] Supposedly, the fruit was initially found during the Edo period by a Chōsokabe Heibei, from whom the fruit got its name (which means "Hebe's vinegar").Chōsokabe began growing it on his land in what is now the Nishikawauchi Tomitaka area of Hyūga city.
