According to the *Guangzhou Ji*: It grows in the valleys of the South Sea, growing as a vine. Mice love to eat it, hence the name "Shu Teng" (Rat Vine). People immediately use it as medicine where bitten by mice. Locals eat it, feeling like eating sugarcane. The taste is sweet and delicious. It primarily treats wind-cold in the waist and legs, greatly tonifies the Kidney Water (Kidney Yin), improves complexion, and strengthens bones and tendons. It should be chopped, decocted strongly, and taken orally. Alternatively, extracting the juice to soak in wine is even better.

According to the *Nei Dian* (Buddhist Scriptures): Its appearance resembles the locust tree. The *Yiwu Zhi* states: Its leaves resemble those of the Chinese toon.

It grows in the mountains of various regions in the South Sea. It produces fragrance after five or six years of planting.

According to the *Guang Zhi*: It grows in various countries of the South Sea. The tree's stem, leaves, roots, and trunk differ from Dafuzi (Areca catechu seed). It is also described as resembling a palm tree, with green leaves shaped like banana leaves. Tao Hongjing stated: Those facing the sun are called Binglang (Areca nut); those facing the shade are called Dafu. The taste is astringent, nature warm, non-toxic. It primarily treats Ben Tun Qi (a condition characterized by gas rushing from the lower abdomen to the chest/throat), Wu Ge Qi (Qi stagnation in five diaphragms), wind-cold qi, and undigested food retention. The *Xianggangjiao Lun* states: Grind one Areca nut in a cup of sand cow urine, take warm on an empty stomach to treat Xianggangjiao (Beriberi/Foot Qi) with toxic congestion and edema/fluid retention. Doctors from Qin state: Use two Areca nuts, one raw and one cooked, grind into powder, decoct in wine, and take. This effectively treats various Qi stagnation disorders of the Bladder.
