Relevant Discussion 相关论述

"Compendium of Materia Medica Illustrations and Elaborations on Plant Names and Realities": "When the beans are tender, they can be used as vegetables. When mature, they can be stir-fried. In southern regions where black beans are not available, these are used as horse feed, precisely because their nature is not heat-inducing. Li Shizhen considered the 'Hu Dou Zi' mentioned in Collected Annotations to be peas, unaware that there is another kind of Hu Dou that is quite different from peas. Thus, the therapeutic indications he cited cannot be generalized."
《植物名实图考长编》：“其豆嫩时作蔬。老则炒食。南方无黑豆，取以饲马，亦以其性不热故也。李时珍以《拾遗》之胡豆子为即豌豆，不知别有胡豆，与豌豆殊不类，其所引治症，未可一例。”
