Key Takeaways
- Summer heat (暑, shu) is a yang pathogen that consumes qi and fluids, causing thirst, fatigue, and irritability.
- The TCM strategy for summer: clear heat, generate fluids, and resolve dampness (humidity compounds heat).
- Chrysanthemum + goji clears Liver heat; mung bean clears heat and detoxifies; lotus leaf resolves damp-heat.
- Mint cools through the Lung; honeysuckle clears heat toxicity; hawthorn generates fluids and aids summer digestion.
- Cooling teas should be drunk warm or at room temperature — ice-cold drinks shock the Spleen and worsen dampness.

Summer in TCM is the season of fire and earth. The Heart fire is most active, the Spleen is most vulnerable (cold drinks and damp heat weaken it), and the body loses fluids through sweat. The classical strategy is not simply to “cool down” with ice — in fact, TCM cautions against ice-cold drinks, which shock the Spleen, impair digestion, and paradoxically worsen the feeling of internal heat by trapping it beneath a layer of cold. Instead, the tradition favours teas that clear heat through the body's natural channels: urination, gentle sweating, and the Liver's dispersing function.

Summer Heat in TCM Theory
Summer heat (暑, shu) is one of the six external pathogens in TCM. It is strongly yang in nature — it ascends, scatters, and consumes. Its hallmark signs are profuse sweating, thirst, fatigue, irritability, and in severe cases, dizziness and confusion. Because sweating consumes qi and fluids, summer heat simultaneously creates qi deficiency (fatigue, shortness of breath) and yin/fluid deficiency (dry mouth, scanty urine). This is why a hot afternoon leaves you not just hot but tired and dry.
Compounding this, summer humidity creates damp-heat. When heat and dampness combine, the result is the classic summer malaise: heavy limbs, foggy head, loss of appetite, sticky sweat that does not evaporate, and a greasy tongue coating. The Spleen — the organ most averse to dampness — struggles, and digestion slows. This is why rich, heavy meals feel unappealing in summer and why the traditional summer diet leans toward light, cooling, slightly bitter foods.
TCM strongly cautions against ice-cold drinks in summer. Cold shocks the Spleen and Stomach, contracting the digestive vessels and impairing the very transformation function that generates qi and fluids. The result is a paradox: you feel momentarily cooled but become more sluggish and damp over time. Drink cooling teas warm or at room temperature for the best effect.
Six Cooling Teas for Summer
Chrysanthemum and Goji Tea (Ju Hua Gou Qi Cha, 菊花构杉茶)
Pattern it suits: Liver heat with yin consumption — dry eyes, headache, irritability, feeling of heat in the head and face, thirst.
Ingredients: 8–10 dried chrysanthemum flowers, 1 tablespoon dried goji berries, 2 cups water.
Nature, flavor & meridians (性味归经): Chrysanthemum: cool, sweet/bitter, Lung/Liver. Goji: neutral, sweet, Liver/Kidney. Together they clear heat while replenishing the fluids that heat has consumed.
Ascending / descending / floating / sinking (升降浮沉): Ascending and dispersing (chrysanthemum) balanced by nourishing and slightly descending (goji).
Traditional use (功效): Traditionally used to clear Liver heat, benefit the eyes, and nourish Liver and Kidney yin. This is the most popular summer tea in China — the chrysanthemum clears the heat, the goji replaces the fluids. See our chrysanthemum tea guide and goji tea guide.
Brewing method (冲泡方法): Place chrysanthemum and goji in a glass. Pour hot water (85–90°C) over them and steep 5–7 minutes. The goji berries plump and can be eaten. Drink 1–2 cups daily, warm or at room temperature.
Compatibility & contraindications (配伍禁忌): No major classical incompatibility. The pairing is traditional and well balanced.
Precautions (注意事项): Chrysanthemum is cooling; those with cold digestion should add a slice of ginger or drink it less frequently. Goji should be used cautiously with anticoagulant medication.
Mung Bean Tea (Lǘ Dou Cha, 绿豆茶)
Pattern it suits: Heat toxicity and summer heat — thirst, irritability, restlessness, heat rash, boils, dark or scanty urine.
Ingredients: 1/2 cup dried mung beans, 4 cups water.
Nature, flavor & meridians (性味归经): Cold in nature, sweet in flavour, enters the Heart and Stomach meridians.
Ascending / descending / floating / sinking (升降浮沉): Descending — it drains heat downward through urination.
Traditional use (功效): Traditionally used to clear heat, resolve summer heat, detoxify, and promote urination. Mung bean is the classic summer food-herb in Chinese households — drunk as a thin soup or tea on hot days. It is one of the strongest heat-clearing substances in the everyday pantry.
Brewing method (冲泡方法): Rinse 1/2 cup of dried mung beans. Bring 4 cups of water to a boil, add the beans, and simmer for 15–20 minutes until the water turns slightly green and the beans are just splitting. Strain the liquid and drink warm or at room temperature. The beans can be eaten with a little sugar.
Compatibility & contraindications (配伍禁忌): Avoid combining with warming tonics. Best consumed on its own or with a little rock sugar.
Precautions (注意事项): Mung bean is quite cold; those with cold digestion (loose stools, cold hands) should not drink it daily. Avoid during menstruation if you tend toward cold. Not suitable for long-term use.
Lotus Leaf Tea (He Ye, 荷叶)
Pattern it suits: Damp-heat in the Spleen — heaviness, foggy head, sluggishness, abdominal bloating, loss of appetite in humid weather.
Ingredients: 1–2 teaspoons dried, crumbled lotus leaf.
Nature, flavor & meridians (性味归经): Neutral (slightly cool) in nature, bitter and sweet in flavour, enters the Spleen and Stomach meridians.
Ascending / descending / floating / sinking (升降浮沉): Ascending — it raises the clear yang, clearing the foggy heaviness that dampness creates.
Traditional use (功效): Traditionally used to resolve summer heat, raise the clear yang, and “cut grease.” Lotus leaf is the traditional southern Chinese summer tea for the heavy, sluggish feeling of humid weather — it lifts the foggy head and lightens the body.
Brewing method (冲泡方法): Steep 1–2 teaspoons of dried crumbled leaf in hot water for 5–7 minutes, or simmer for 5 minutes. Drink 1–2 cups daily during hot, humid weather.
Compatibility & contraindications (配伍禁忌): Can be combined with hawthorn for digestive support. Avoid pairing with strongly astringent herbs.
Precautions (注意事项): Generally mild and well tolerated. Those with very cold Spleen patterns should add ginger. Avoid during pregnancy.
Honeysuckle Tea (Jin Yin Hua, 金银花)
Pattern it suits: Heat toxin or early wind-heat — sore throat, fever with slight chill, red swollen tonsils, summer skin eruptions.
Ingredients: 1 tablespoon dried honeysuckle flowers.
Nature, flavor & meridians (性味归经): Cold in nature, sweet in flavour, enters the Lung, Heart, and Stomach meridians.
Ascending / descending / floating / sinking (升降浮沉): Ascending and dispersing — it vents heat outward.
Traditional use (功效): Traditionally used to clear heat and dissipate fire toxicity, especially in the throat and on the skin. Honeysuckle is the summer tea for the first sign of a sore throat or a heat rash — it clears heat quickly but should be used short-term.
Brewing method (冲泡方法): Steep 1 tablespoon in hot water for 5–7 minutes. Drink 1–2 cups at the first sign of heat symptoms, then discontinue once they pass.
Compatibility & contraindications (配伍禁忌): Avoid pairing with warming tonics like ginseng or astragalus.
Precautions (注意事项): Honeysuckle is cold and should not be consumed for more than a few days. Avoid in cold-deficiency patterns. Not suitable for pregnant women without professional guidance.
Mint Tea (Bo He, 薄荷)
Pattern it suits: Wind-heat at the exterior — headache, sore throat, feeling of heat with slight chill, foggy head, chest tightness from heat.
Ingredients: A small handful of fresh mint leaves, or 1–2 teaspoons dried mint.
Nature, flavor & meridians (性味归经): Cool in nature, pungent in flavour, enters the Lung and Liver meridians.
Ascending / descending / floating / sinking (升降浮沉): Ascending and dispersing — it vents heat outward through the skin and Lungs.
Traditional use (功效): Traditionally used to disperse wind-heat, clear the head and eyes, vent rashes, and soothe Liver qi. Mint is the most accessible cooling herb in the Western pantry and grows easily in a garden or pot. Its pungent-cool nature vents heat outward through gentle sweating.
Brewing method (冲泡方法): Steep fresh or dried mint in hot water (just off the boil) for 3–5 minutes. Do not simmer — the volatile oils that give mint its cooling effect are lost with prolonged heat. Drink 1–2 cups daily.
Compatibility & contraindications (配伍禁忌): Do not combine with astringent herbs that would counteract its dispersing action.
Precautions (注意事项): Mint should be avoided by nursing mothers in large amounts (traditional caution). Those with cold deficiency should pair it with a small piece of ginger.
Hawthorn Tea (Shan Zha, 山楖)
Pattern it suits: Fluid deficiency with food stagnation — thirst, loss of appetite, heaviness after meals, sluggish digestion in hot weather.
Ingredients: 1–2 tablespoons dried hawthorn slices; optional rock sugar.
Nature, flavor & meridians (性味归经): Warm in nature, sour and sweet in flavour, enters the Spleen, Stomach, and Liver meridians.
Ascending / descending / floating / sinking (升降浮沉): Descending — it helps move stagnant food downward.
Traditional use (功效): Traditionally used to promote digestion, move blood, and transform stasis. In summer, hawthorn's sour-sweet flavour generates fluids (sour astringes and generates fluids in TCM theory) while aiding the digestion that heat and dampness have slowed. See our hawthorn tea guide.
Brewing method (冲泡方法): Simmer 1–2 tablespoons in 2 cups of water for 10–15 minutes. Add rock sugar to taste. Drink 1 cup after meals, especially in hot weather when appetite is low.
Compatibility & contraindications (配伍禁忌): Traditionally incompatible with ginseng.
Precautions (注意事项): Hawthorn is sour; do not drink on an empty stomach. Those on anticoagulant or blood-pressure medication should consult their provider.
A Summer Tea Routine
- Morning: A cup of lotus leaf or hawthorn tea to wake the Spleen and prepare for the day's heat.
- Midday: Chrysanthemum and goji tea after lunch to clear heat from the head and eyes.
- Afternoon: Mint tea for a gentle cooling lift, or mung bean tea on the hottest days.
- Evening: Return to room-temperature water. Avoid cooling teas right before bed if you tend toward cold at night.
- Temperature: Drink all teas warm or at room temperature. Ice-cold drinks impair the Spleen and paradoxically worsen internal heat. For seasonal context, see our winter warming teas for the counterpart guide.
The Bottom Line
Summer in TCM calls for a strategy of clearing heat, generating fluids, and resolving dampness — not shocking the body with ice. Chrysanthemum and goji clear Liver heat while replenishing fluids. Mung bean clears deep heat. Lotus leaf lifts the foggy heaviness of damp-heat. Honeysuckle tackles heat in the throat. Mint vents heat outward. Hawthorn generates fluids and supports digestion. Brewed warm and matched to your pattern, these six teas form a simple, effective framework for summer wellness. For the full safety context, see our herbal tea safety guide.
Frequently Asked Questions
Why does TCM say not to drink ice water in summer?
TCM views ice-cold drinks as a shock to the Spleen and Stomach. The cold contracts the digestive vessels, impairs transformation, and can trap heat beneath a layer of cold — paradoxically worsening internal heat over time. The tradition favours warm or room-temperature drinks that clear heat through the body's natural channels (urination, gentle sweating) rather than suppressing it with cold.
Can I drink mung bean tea every day in summer?
Mung bean is quite cold and is best consumed 2–3 times per week on the hottest days, not daily. If you notice loose stools, cold hands, or fatigue, reduce the frequency. Those with a cold constitution should choose milder cooling teas like chrysanthemum or lotus leaf instead.
Which cooling tea is best for humid weather?
Lotus leaf is the best choice for damp-heat — the heavy, foggy, sluggish feeling that comes with humidity. It resolves dampness while raising the clear yang. If you also have digestive heaviness, add a little hawthorn.
Are cooling teas safe during pregnancy?
Several cooling herbs — particularly honeysuckle, mung bean in large amounts, and mint — are traditionally used with caution during pregnancy. Chrysanthemum in small amounts is generally considered acceptable. Always consult your obstetric provider before using any herbal tea during pregnancy.
