RemarksThe original plant of Diyu (地楡) is Sanguisorba officinalis. The variants include var. longifolia (Bert.) Yu et Li, var. carnea (Fisch.) Regel ex Maxim. (Jap. name: Ezowaremokō), var. glandulosa (Kom.) Worosch and var. longifolia (Kitag.) Yu et Li.
Besides the above, the root of following plants are used for medicinal purposes:
S. tenuifolia Fisch. ex Link and S. tenuifolia Fisch. ex Link var. alba Trautv. et Meyer (Nagabonoshirowaremokō in Jap.) in northeast of China, S. applanata Yu et Li and its variants in Yantai of Shandong, S. alpina Bunge in a part of Ningxia.
Also, the rhizome of Polygonum bistorta L. of family Polygonaceae (Ibukitoranoo in Jap.) is called Diyu in Guiyang of Guizhou and the rhizome of Polygonum cuspidatum Sieb. et Zucc. (Itadori in Jap.) is called "Tudiyu" (土地楡, Dochiyu in Jap.) in southern Sichuan.
As for the rest, in Xinyang of Henan the rhizome of Astilbe chinensis Maxim. ex Fr. et Sav. of family Saxifragaceae is called "Zidiyu" (紫地楡, Shichiyu in Jap.) or "Chidiyu" (赤地楡, Sekichiyu in Jap.) which is also the name for the root of Geranium strictipe Kunth of family Geraniaceae in Kunming of Yunnan. Additionally, in a part of Yunnan, the root of Potentilla peduncularis D. Don of family Rosaceae and P. siemersiana Lehm. are called "Baidiyu" (白地楡, Hakuchiyu in Jap.). However, all of them are misused for Diyu.
