However, according to physician Sang, some people should not eat chrysanthemum greens because it can make their condition worse:

First, people with diarrhea and cold stomach:If you eat more cool chrysanthemum greens, the patient will feel more uncomfortable. In these cases, you should use hot foods to balance the situation.

Second, people with low blood pressure: This vegetable is good for people with high blood pressure and high cholesterol, but is contraindicated for people with low blood pressure because it can cause the patient to lower their blood pressure even more. Some cases with normal blood pressure also have a slight drop in blood pressure if they eat too much of this vegetable.
