What is Longan Aril?
Longan Aril (long yan rou, 龙眼肉) is the ripe pulp of the fruit of an evergreen tropical tree which is native to Southern Asia and later introduced to India and other warm regions such as Thailand, Cambodia, Laos, Vietnam and Malaysia in the 18th century. Its Chinese name Long Yan Rou means the flesh of the Dragon’s eye. It is named so due to the translucent white colour of the fresh, peeled fruit and the dark brown seed that shows through the flesh, which resembles the bulging pupils of a Dragon.
In the early Autumn, after harvesting these ripe pupils, the small, round and hard seeds are removed before Longan Aril can be sold to its consumers. The dried Longan fruits then become a lovely golden colour and acquire a unique flavour. The Compendium of Materia Medica stated that good quality Longan fruit is large, thick, soft, yellowish and translucent with an intensely sweet taste.
In Traditional Chinese Medicine (TCM), Longan Aril falls under the category of ‘Tonic herbs for Blood Deficiency’, Such herbs are used for patterns of Deficiency to replenish one’s ‘Four Treasures’ (qi, blood, yin, yang). Warm in nature, the herb can also help individuals who are experiencing too much ‘Cold’ in their body, such as those having a Yin Excess or Yang Deficiency, to restore a healthy yin-yang balance.
Sweet in taste, Longan Aril tends to slow down acute reactions, detoxify the body, and has a tonic effect on the human body by replenishing qi and blood. In particular, Longan Aril targets the Heart and the Spleen.
