Longan fruit is a tropical fruit that grows on the Longan tree, a small tree native to China. A cousin of the lychee, it is very popular in Asia for its very sweet pulp. In traditional Chinese medicine, dried longan (Long yan rou in Chinese) is one of the plants that tonify the Blood.

Indeed, Long yan rou tones and increases the Heart and the Spleen, nourishes the Blood and calms the Shen (the Spirit). Thus, this fruit preserves the balance of the body and allows a regain of tone.
