[Origin] *Tujing Bencao* states it grows on the north side of Mount Tai. Su Gong says it comes from the mountains of Cizhou; it is not heard that it grows on the left side of Mount Tai. Currently, it is only found in Luzhou Prefecture. Luzhou is close to Cizhou, so the local product should also be usable. It was frequently used in ancient formulas and is still widely used by physicians today.
[Origin Supplement] *Tangben Zhu* notes it comes from the mountains of Yuhang, Hangzhou, which are no longer harvested; Suzhou now offers it as tribute, but it is not very suitable for medicinal use. The best quality comes from the mountains of Yanzhou. It is extracted between two stones. In Yanzhou, when besieged by foreign enemies and lacking water, people dig pits three to five zhang deep and wide, sealing them with a mixture of earth lipid and honey to store water, which remains non-leaking for a long time. This method is considered optimal.
