Relevant Discussion

"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."
