【Excerpt】 《*Dictionary》

[Source] From Compendium of Materia Medica: Wei grows in wheat fields and also in marshes. Therefore, it is said in the Book of Songs that there are ferns on the mountain. It is not a water plant. That is the present-day wild pea. The people of Shu call it nest vegetable. It is a creeping plant, and its stems and leaves smell like peas. It is suitable as a vegetable or in soups. "Shishu" thinks it is a fern, and Zheng's "Tongzhi" thinks it is a golden cherry bud, both of which are wrong. Xiang said that there are two kinds of nest vegetables, large and small. The large one is the wild pea, which is the non-fruitful version of the wild pea, and the small one is what Su Dongpo called Yuanxiucai. This statement is correct.

Through the detailed introduction of the giant nest vegetable, I believe everyone has a certain understanding and can better improve our common sense of life.
