Can Lycium barbarum (goji berries), red dates (jujubes), and chrysanthemum be steeped together in water for consumption?
Under normal circumstances, goji berries, red dates, and chrysanthemum can be consumed together as a herbal tea, but moderation should be observed when consuming them. Detailed explanations are as follows:

Goji berries, red dates, and chrysanthemum each offer certain health benefits. Goji berries can improve vision and nourish the liver and kidneys; red dates have the effect of replenishing qi and nourishing blood; chrysanthemum can soothe the liver, improve vision, clear heat, and detoxify. When combined, these three ingredients can provide health benefits such as clearing heat, improving vision, and promoting general wellness when consumed in moderation by healthy individuals.
However, excessive consumption may lead to physical discomfort, such as heatiness or indigestion. It is generally recommended to consume 1–2 cups per day. Additionally, due to their high sugar content, red dates may not be suitable for people with diabetes to consume in large quantities. Moreover, because chrysanthemum has a cooling nature, individuals with cold deficiency of the spleen and stomach should consume it in small amounts to avoid worsening symptoms. Those with a cold due to寒邪 (cold pathogenic factors) should avoid consuming it altogether.
In daily life, maintaining a balanced diet and drinking such herbal teas in moderation will help maximize their health benefits. It is also important to monitor your body's response, and if any adverse reactions occur, discontinue use immediately and consult a healthcare professional.
