Can chrysanthemum and rose flowers be steeped together in water for drinking?
Generally, chrysanthemum and rose petals can be steeped together in water for drinking, but should be consumed in moderation. The detailed explanation is as follows:

Chrysanthemum is slightly cold in nature and sweet in taste, and has the effect of clearing heat and soothing the liver. Rose petals are warm in nature, sweet and slightly bitter in taste, and help regulate qi and relieve depression. Their medicinal properties complement each other—chrysanthemum's slight coolness balances the warmth of rose petals, preventing excessive internal heat, while the warming quality of roses moderates the cold nature of chrysanthemum, reducing the risk of harming the spleen and stomach. When steeped together, their fragrances blend into a refreshing and pleasant aroma, helping to ease emotional stress and relieve discomforts such as dry mouth and dry eyes. This combination is suitable for daily use to soothe the liver, relieve depression, clear heat, and moisten dryness, with no ingredient conflicts and harmonious flavor.
When purchasing, choose dried chrysanthemum and rose petals with intact petals and natural color, avoiding those fumigated with sulfur. Rinse quickly with warm water before brewing to remove surface dust. Use water around 80°C, cover, and steep for about 5 minutes. Individuals with deficiency-cold in the spleen and stomach should reduce the amount of chrysanthemum, and women during menstruation should moderately decrease the quantity of rose petals. Store the herbs sealed in a cool, dry, dark place to prevent dampness, mildew, and loss of fragrance. Do not use excessive amounts—3–5 grams of each is sufficient. Replace with fresh herbs once the flavor becomes weak.
