Extended data:

The following people should not drink chrysanthemum tea.

Pregnant women: Chrysanthemum tea is cold and sweet, and has an excellent effect of removing internal heat. However, pregnant women have low immunity and weak spleen and stomach. Eating chrysanthemum tea can easily stimulate the stomach, causing abdominal pain, diarrhea and other symptoms, which is not conducive to the healthy growth of the fetus.

Hypotension: Because scented tea generally has a little antihypertensive effect, if people with low blood pressure drink chrysanthemum tea, they may feel dizzy. People with low blood pressure cannot drink chrysanthemum tea.

People with cold constitution: people with cold constitution are afraid of cold, weak in body, weak in spleen and stomach and low in immunity. Even in summer, they will have cold hands and feet, diarrhea, gastrointestinal discomfort and other symptoms. Cold chrysanthemum tea will only aggravate their symptoms and be harmful to their health.

Allergic people: In our real life, some people are allergic to chrysanthemum tea. If you drink chrysanthemum tea, it will cause allergic phenomena such as skin redness and rash. So people who are allergic to chrysanthemum tea will have side effects, which is not good for their health.

Diabetic patients: People with diabetes or high blood sugar should not drink sweetened chrysanthemum tea, and it is best not to drink more than three at a time. If you really want to drink tea, I suggest drinking mint tea and rose tea instead, but remember that everything will be counterproductive, so you must not drink too much.

People with yang deficiency constitution: people with yang deficiency constitution, if they blindly drink chrysanthemum tea with the effect of clearing away heat and purging fire, will easily damage healthy qi, and the more they drink, the weaker they will become, especially those with spleen and stomach deficiency and cold. Drinking more cool chrysanthemum tea is easy to cause stomach discomfort and lead to acid reflux.
