Drinking chrysanthemum tea before bedtime can help relax the body and mind, allowing you to fall asleep more easily. Additionally, it can help reduce stress and anxiety levels, allowing you to feel calmer and more relaxed before bedtime. It is important to note though that drinking too much chrysanthemum tea can have a stimulating effect, so it is best to drink in moderation.
