This is chrysanthemum brain. Chrysanthemum is a close relative of the herbaceous chrysanthemum of the Asteraceae family. There are two types of chrysanthemum: small-leaf chrysanthemum and large-leaf chrysanthemum. The one with larger leaves is better in quality. Chrysanthemum brains are the most common dishes on folk tables, especially chrysanthemum brains and egg soup, which is a good way to prevent heatstroke in summer. Chrysanthemum brains are not only rich in nutrients, but also have the effects of clearing heat, detoxifying, regulating the body, appetizing, and lowering blood pressure. It is a wild vegetable with great development prospects. In the Jiangsu area, this wild vegetable is mainly eaten by residents near Nanjing.
