Cooling Drinks from the Chinese Medical Tradition
Watermelon, cucumber, and what summer heat actually requires
Traditional Chinese Medicine (TCM) has been thinking about food as medicine for two thousand years. The framework is different from Western nutrition. In TCM foods are classified by their thermal nature, their effect on the body’s internal climate.
TCM holds that every food has a heating or cooling action on the body. Watermelon, cucumber, mint, and mung beans are all classified as cold or cool in nature. They clear what practitioners call summer heat, support the kidneys, and calm “heart fire” which is the agitated, sleepless, short-tempered state that sustained heat tends to produce. The system operates through the concepts of qi (vital energy) and the balance of yin and yang, and in summer the heart is the governing organ. The goal is to cool from the inside out.
Western nutrition confirms the basics independently: watermelon is 92% water and rich in lycopene, citrulline, and potassium. Cucumber is 96% water with electrolytes and B vitamins. The cooling effect is real and measurable, not only theoretical.
Three Recipes
Watermelon & Mint Cooler
Blend 4 cups of seedless watermelon until smooth. Add the juice of half a lime and 8–10 fresh mint leaves; blend briefly. Strain through a fine mesh or serve as-is over ice. If you don’t have lime & you don’t have mint… just enjoy some watermelon- still nicely cooling!
Watermelon clears heat and promotes fluids; mint moves stagnant qi and has a lightening effect on the chest and mind. Together they’re the most straightforward version of summer cooling TCM offers.

Cucumber, Ginger & Honey Infusion
TCM doesn’t recommend blasting the body with cold. The idea of a summer filled with iced drinks is associated with weakened digestive fire which we need to properly break down and absorb nutrition from our food. The goal is to have overall thermally balanced foods and drinks. A small amount of ginger, which is warming, helps cooling foods work more effectively by keeping circulation moving and protecting digestion.
Thinly slice half a cucumber. Combine with 3 cups of water, 3–4 slices of fresh ginger, a tablespoon of honey, and a few leaves of basil or mint. Refrigerate for at least two hours or overnight. Strain and serve cold.
Serves 2–3.
Mung Bean & Chrysanthemum Tea
This is the classic Chinese summer remedy and the combination found in home kitchens across China from June through August. Chrysanthemum (菊花, júhuā) clears liver heat , brightens the vision and calms the nervous system. Mung beans clear heat and have a clean, mild flavor somewhere between green tea and lentils. Dried chrysanthemum flowers are available at most Asian grocery stores. You can also enjoy iced chrysanthemum tea (sweetened or not) on it’s own.
Rinse ¼ cup of mung beans and soak for two hours, then drain. Simmer in 5 cups of water for 20 minutes, until the beans begin to split. Add 3 tablespoons of rinsed dried chrysanthemum flowers and a tablespoon of rock sugar or honey; simmer another 5 minutes. Strain and serve warm or at room temperature — ice-cold is not traditional here, and TCM considers it a stress on the digestive system.
Serves 3–4.
The Mind in Summer
TCM has a concept called shen which is usually translated as spirit or mind. Shen is associated with the heart and becomes vulnerable when summer heat is prolonged. Disturbed shen shows up as poor sleep, scattered concentration, and irritability. Chrysanthemum and mint act specifically on the heart meridian and nervous system; their calming effect has been observed by practitioners for centuries and is increasingly supported by contemporary herbalism.
There is also something to be said for the preparation itself. Infusing, waiting, paying attention to temperature. Even slowing down to engage in small acts of deliberate preparation can slow us down and counter summer’s heat.
Dried chrysanthemum flowers and mung beans are available at Asian grocery stores and online. Look for whole flowers intended for tea. They are gorgeous to watch as you pour hot water on them and they expand. Rock sugar can be replaced with honey, maple syrup or omitted.
