《本草纲目》：“赤者杜，白者棠；或云牝曰杜，牡曰棠；或云涩者杜，甘者棠。杜者涩也，棠者糖也，三说俱通，末说近是。棠梨，野梨也。霜后可食，其树接梨甚嘉，有甘酢、赤白二种。”临床应用 相关配伍
"Compendium of Materia Medica": "Red is called 'Du', white is called 'Tang'; some say female is called 'Du', male is called 'Tang'; some say astringent is 'Du', sweet is 'Tang'. 'Du' is astringent, 'Tang' is sweet, all three explanations are plausible, but the last one is more accurate. 'Tangli' refers to wild pears. They can be eaten after the frost, and the grafted pears on the tree are excellent, with two varieties of sweet and sour, red and white." Clinical applications and related compatibility.
