Origin, growth environment and varieties of longan

Since ancient times, Li Shizhen recommended longan as the best tonic, and people still like to eat longan today.

Longan

Longan, also known as longan, is one of the rare fruits in the subtropical region and an important tonic. It is named because its seeds are round and black, and its navel is white, which looks like the eyes of the legendary "dragon". Fresh longan is very tender, juicy, sweet, and delicious, which is beyond the reach of other fruits. Fresh longan is dried into dried fruit and becomes longan in traditional Chinese medicine.

Longan was cultivated before the Han Dynasty. It is said that Zhao Tuo, the King of Nanyue, once offered longan as tribute to Emperor Gaozu of Han. The Shennong's Herbal Classic states that "longan can strengthen the mind and intelligence, and keep the body light and young". The Southern Plants and Trees states that "Emperor Wen of Wei summoned his ministers and said: The true fruits of the south are longan and lychee", and gave a detailed description of their growth and shape. Regarding their health benefits, Li Shizhen said that "lychee is the best food, and longan is the best for nourishing."
