Crown Daisy (Tong Hao) and Egg White Soup

Why people make this soup

When late autumn rolls around, crown daisy greens (tong hao) come back to the markets. For middle-aged and older folks with high blood pressure, the usual advice is more vegetables and less meat — but if your stomach runs a little cold, you can’t take too many cooling greens. Crown daisy is the friendly exception: warmer-natured and easy on the gut. Nourilo cooks it into a quick soup with egg white, traditionally used to soothe the stomach, ease phlegm, and clear that heavy, dizzy-headed feeling some people get with high blood pressure.
