Non-toxic. Upright plant. Chestnut (Lizi) mainly benefits qi, thickens the stomach and intestines, tonifies kidney qi, and enables endurance of hunger (Recorded by Famous Physicians). [Names] [Bark] Fu. [Seedlings] [*Tujing* states] The tree is two to three zhang high, with cracks and broken branches. Chestnuts are sweet and delicious; those produced elsewhere do not compare. Chestnuts from Wa (Japan), Korea, and various islands are large as chicken eggs but short and tasteless. Guiyang has Xin chestnuts growing in clusters, fruits as large as apricots, with kernels, bark, and seeds identical in color and shape to common chestnuts, only slightly smaller. There are also Ao chestnuts, identical to common chestnuts, round and fine seeds; some say these are Xin chestnuts. Currently, this colored variety exists only in the Jianghu region. There are also Mao chestnuts (pronounced zhui), whose fruits are even smaller, trees indistinguishable from common chestnuts, differing only in spring sprouting, summer flowering, autumn fruiting, and winter withering. A single seed in the center of the burr is called "Li Xie" (Chestnut Wedge), especially effective for treating blood disorders. [Tao Hongjing says] Currently, Kuaiji produces the most Puji (pronounced ji) chestnuts, which are large but have thick, unappealing skin; Shan (pronounced shi ran qie) and Feng chestnuts have thin, sweet skins. It is said that someone suffering from weak legs ate several sheng of chestnuts under a chestnut tree and could then walk, illustrating the principle of tonifying the kidneys. However, they should be eaten raw; if used medicinally, steaming and drying are suitable. [Origin] [*Tujing* records] Flowers in autumn, fruits mature. [Harvest] Collect fruits in September.
