Why Does Chrysanthemum Tea Turn Green?

If chrysanthemum tea turns green after steeping, it may be due to several factors, including prolonged soaking time, high water temperature, or alkaline water quality.

1. Prolonged Soaking Time: Chrysanthemum should not be steeped for too long. If the soaking time is excessive, the chlorophyll from the petals can dissolve into the water, causing the tea to take on a green color. Once the petals have changed color, it’s best not to consume the tea, as it may lead to bloating or diarrhea.
2. High Water Temperature: The water used for steeping should not be too hot. High temperatures can increase the activity of substances in the chrysanthemum, promoting the dissolution of chlorophyll and resulting in a green tea.
3. Alkaline Water: Chrysanthemum contains anthocyanins, which can react chemically with alkaline substances, leading to a change in color. Therefore, using alkaline water to steep chrysanthemum can also cause the tea to turn green.

From a traditional Chinese medicine perspective, chrysanthemum is considered cooling and slightly bitter, with benefits like dispersing wind and clearing heat, detoxifying, and reducing swelling. It can effectively alleviate symptoms of wind-heat colds and is rich in lignans and cellulose, which promote intestinal movement, lower blood pressure, and reduce blood lipids. This can help in preventing atherosclerosis and cardiovascular diseases.

While chrysanthemum tea offers many benefits, it may not be suitable for everyone, especially those prone to allergies.
