Su Song stated: Bai Lian is rarely used in prescriptions for ingestion and alchemy, but is frequently used in formulas for astringing sores; hence its name Bai Lian.
Li Shizhen stated: "Huhé" (Rabbit Testicle) and "Maorluan" (Cat Egg) both describe its shape. "Kunlun" refers to its black skin.
**[Collection and Explanation]** *Mingyi Bielu* states: Bai Lian grows in the valleys of Mount Heng. The roots are harvested in February and August and dried in the sun.
Tao Hongjing stated: It grows everywhere in nearby regions. It is a vine; the root resembles *Atractylodis Rhizoma* (Baizhi, 白芷). It is sliced and threaded on bamboo sticks for sun-drying.
Zhen Gong stated: The root resembles *Asparagi Radix* (Tiandong, 天门冬). One plant has about ten roots beneath it; the skin is reddish-black, the flesh white, resembling *Paeoniae Radix Rubra* (Chishao, 赤芍), unlike *Atractylodis Rhizoma*.

The roots are elongated like chicken or duck eggs, with three to five growing from one cluster; the skin is black and the flesh white.
