History and Traditional Uses of Kuko
Kuko is a deciduous shrub, native to Japan, Korea and China. It grows wild in wastelands and embankments and also finds its way into gardens. In summer, it bears pale purple flowers similar to those of a tomato or eggplant. These small flowers are followed by orange colored round fruits in autumn. The fruits and root bark are used medicinally while the leaves are used as vegetable.
Kuko is mentioned in the oldest Chinese herbal “Sinnouhonzougyou” (Divine Husbandman’s Classic of the Materia Medica) published 1800 years ago. In that text it is classified as superior tonic suitable for long term usage. The Chinese say it has the capacity to nourish “life force” and rejuvenate a person. According to this book, the fruits nourish the liver and kidney and make an excellent tonic in fatigue, lumbago, dullness, vertigo, anemia, and failing eyesight. The root bark is recommended to reduce fevers. In short, the ancient text suggests the drug as a powerful tonic for those failing to thrive.
Early in the eighth century Kuko appears in Japanese literature. By the early tenth century, it was an item presented to the Japanese royal court as a gift of great value. Highly prized by noblemen of the day as a vitality boosting tonic, Japanese peasants were encouraged to cultivate the plant. (This is probably why the plant can now be found growing wild in so many places in Japan.) From ancient times forward, legendary figures were reported to have lived to be over a hundred years of age and to be forever young as a result of daily Kuko use. The plant was seen as a panacea, able to heal whatever ailed you and to prevent you from ever ailing from anything!
