Can the flowering parts of Clinacanthus nutans be eaten?

Generally speaking, the flowers of Clinacanthus nutans are edible, but excessive consumption is not recommended. The detailed explanation is as follows:

Clinacanthus nutans flowers have a pungent taste and cool nature. They are rich in beneficial nutrients essential for the human body, including betulin, pentacyclic diterpenes, flavonoids, amino acids, chlorophyll, vitamin C, and dietary fiber. These components endow the flowers with functions such as clearing heat, eliminating dampness, relaxing tendons, and promoting blood circulation.

The flowers can be eaten by briefly blanching and serving cold or boiling and drinking the liquid. However, it should be noted that consuming too much at once may irritate the gastrointestinal tract, potentially causing symptoms such as bloating and vomiting; therefore, moderate intake is advised. Additionally, avoid consuming them together with chicken, duck, crab, or similar foods, as this may affect their nutritional value. During consumption, maintain a balanced diet by eating plenty of fresh fruits and vegetables such as apples, bananas, and spinach. Combine this with regular作息 (daily routines) and physical exercise to help enhance overall immunity.
