When July hits its stride and the sun feels less like a gentle friend and more like an overbearing houseguest, my mind drifts to a specific sound from my childhood: the rhythmic thud of a cleaver on a wooden board. My mother, preparing dinner in our family’s sweltering kitchen, would turn to the windowsill, where a small forest of pots held her secret weapons. “Hot weather, cool herbs,” she’d say, snipping a generous handful of mint, its bright, clean scent instantly cutting through the humid air. She wasn’t making a garnish; she was brewing medicine, a practice as natural and unremarkable as turning on a fan. In Traditional Chinese Medicine (TCM), summer is the season of maximum yang energy—outward, expansive, and fiery. The goal isn’t to fight the heat with more cold, but to balance it with gentle, internal cooling, guiding that fiery energy inward to maintain harmony. Your kitchen, it turns out, is your first and best apothecary for this task.

The TCM Concept of “Clearing Summer Heat”
Before we name the herbs, let’s understand the problem they solve. In TCM, we don’t just say “it’s hot.” We diagnose a specific pattern called Summer Heat (暑热, shǔ rè). This isn’t ordinary warmth; it’s a pathogenic factor that invades the body, particularly when our defensive energy (qi) is low from sweating, poor sleep, or stress. Symptoms are distinct: a sudden feeling of heat, heavy sweating that doesn’t relieve the heat, a parched mouth, irritability, and sometimes even a mild fever or nausea. Think of it as your internal thermostat breaking down, leaving your system overheated and your energy scattered.
The herbal strategy here is brilliant in its simplicity: use herbs that have a naturally cooling thermal nature and a dispersing or draining action. They don’t just cool the surface; they help your body vent the excess heat outward, much like opening a window in a stuffy room. They encourage gentle sweating (a therapeutic diaphoretic action, not a drenching sweat), promote urination to flush out heat, and calm the spirit. This is a fundamental pillar of seasonal eating—using food as a precise tool to counterbalance the climate.
1. Mint (薄荷, Bò He) – The Instant Breeze
If summer heat were a stuffy room, mint is the person who throws open the windows and turns on the ceiling fan. Its primary action in TCM is to dispel wind-heat and clear the head and eyes. This isn’t just poetic; it’s practical. That refreshing, almost sharp sensation you feel when you taste mint is its volatile oils (like menthol) at work, triggering cold-sensitive receptors in your mouth and skin. Internally, this translates to a cooling, dispersing effect that can relieve the headache, red eyes, and sore throat that often accompany summer heat.
Actionable Use: Don’t just toss a sprig into your iced tea. For a true therapeutic brew, use it properly. Take 5-6 fresh sprigs (about 1/4 cup packed leaves) or 2 teaspoons of dried mint. Steep in just-boiled water for no more than 3-5 minutes. Over-steeping releases more bitter compounds, diminishing the bright, dispersing quality. Drink it warm or at room temperature for best effect; an ice-cold drink can constrict the stomach and trap the heat you’re trying to release. My mother would brew this for us after we’d been playing outside in the Guangzhou summer heat, and it always seemed to cool us faster than a popsicle.
“Mint doesn’t fight the heat with cold; it invites the heat to leave, like a gentle host showing a disruptive guest the door.”
2. Chrysanthemum (菊花, Jú Huā) – The Eye-Soothers
In China, chrysanthemum tea is the summer beverage of choice, not for its delicate floral taste, but for its profound effect on what TCM calls the Liver system. The Liver is associated with the Wood element and is easily aggravated by heat, leading to symptoms we directly feel in the eyes: redness, dryness, gritty irritation, and headaches centered behind the eyes. This is incredibly common in our screen-saturated summers.
Chrysanthemum’s sweet, slightly bitter flavor has a cooling and nourishing nature. It clears heat and toxins from the Liver channel, directly benefiting the eyes. It’s not just a folk remedy; modern research has identified its rich antioxidants, like luteolin, which support ocular health.
Actionable Use: For a true Liver-cooling tea, use the small, yellow Hangzhou or Anhui chrysanthemum buds. Place 8-10 buds in a glass or ceramic pot (avoid metal, as it can affect the taste). Pour hot water over them, just off the boil (about 185°F/85°C). Let them bloom for 5 minutes until the water turns a pale gold. You can re-steep them 2-3 times throughout the day. For an extra boost, add 5-6 goji berries (枸杞, gǒu qǐ) in the last minute of steeping—the combination is a classic TCM pairing for eyesight, balancing chrysanthemum’s clearing action with goji’s gentle nourishment.
3. Mung Bean (绿豆, Lǜ Dòu) – The Heat Detoxifier
If mint is the breeze and chrysanthemum is the eye-soother, mung bean is the deep cleaner. This humble legume is a powerhouse for clearing heat and resolving toxins from the blood and body. It’s a food-grade herb so potent that it’s the star of the most famous summer detox soup in Chinese culture. My grandmother would make a big pot every Sunday during the hottest months, and we’d drink it lukewarm, sometimes with a tiny piece of rock sugar, sometimes plain.
The logic is beautifully practical. Summer heat can create toxins in the body, leading to skin rashes, boils, or a general feeling of sluggishness. Mung bean, being cool in nature and sweet in flavor, enters the Heart and Stomach channels. It clears summer heat, quenches thirst, and has a diuretic effect, helping to flush out dampness and heat through urination. It’s your internal cooling system’s deep clean cycle.
Actionable Use: Mung Bean Cooling Tea (Lǜ Dòu Tāng). Rinse 1/2 cup of whole mung beans. Place in a pot with 6 cups of water. Bring to a vigorous boil, then immediately turn the heat down to a very low simmer. Cook for only 15-20 minutes. The key is to drink the clear, greenish liquid, not the mushy beans. The beans’ cooling properties are most potent in the early stages of cooking. Strain the liquid, let it cool to room temperature, and drink 1-2 cups daily. You can add a few slices of fresh tangerine peel (Chén Pí) during simmering to add a hint of citrus and aid digestion.
4. Licorice Root (甘草, Gān Cǎo) – The Harmonizer
This one might surprise you. Licorice root? Isn’t that for sore throats? In TCM, licorice is the ultimate team player. Its sweet flavor and neutral-to-warm temperature might seem out of place in a cooling lineup, but its role is critical: it harmonizes the actions of other herbs and protects the Stomach and Spleen. When we consume a lot of cooling foods and herbs in summer (like the mung beans and chrysanthemum above), we risk creating internal dampness or chilling the digestive system, which can lead to bloating or loose stools. Licorice root prevents this.
It’s not a primary cooling herb, but a moderating one. It helps the body absorb and utilize the cooling properties of the other herbs more effectively, and its sweetness has a calming, nourishing effect on the spirit, which can become agitated from summer heat.
Actionable Use: Use it as an adjunct, not the main event. Add a single, 1-inch piece of dried licorice root (available at Asian markets or herb shops) to your mung bean soup or chrysanthemum tea during the last 5 minutes of steeping/simmering. Important Caveat: Licorice root is contraindicated for people with high blood pressure, during pregnancy, and when taking certain medications (like blood thinners or diuretics). If you have any chronic health conditions, consult a healthcare provider or a licensed herbalist before using it regularly.
5. Winter Melon (冬瓜, Dōng Guā) – The Dampness Drain
Don’t let the name fool you—winter melon is a summer superstar. Its name comes from its incredible ability to be stored for months over winter, not its growing season. This large, pale green gourd is a cooling and draining food that enters the Lung, Bladder, and Small Intestine channels. Its primary action is to promote urination and reduce edema. In the sweltering humidity of summer, our bodies can accumulate dampness, leading to that feeling of heaviness, puffiness, and lethargy. Winter melon is a gentle, food-based way to drain that dampness.
Actionable Use: The most potent preparation is Winter Melon Tea (Dōng Guā Chá). This is not made from the flesh, but from the skin and seeds, which hold the strongest diuretic and cooling properties. Take the rind from about 1/4 of a melon (with some flesh attached) and a handful of seeds. Boil them in 8 cups of water for 30-40 minutes. Strain, and you’ll have a slightly sweet, very mild-tasting tea. Drink 1-2 cups cool. This is a classic remedy for summer puffiness and urinary tract discomfort. For a heartier meal, make a simple winter melon and lean pork bone soup—the melon absorbs the savory broth and becomes a silky, cooling vegetable.

Common Questions
Can I use these herbs if I’m already feeling sick with a summer cold?
It depends on the symptoms. If your summer cold presents with clear heat signs—fever, yellow phlegm, sore throat, intense thirst—then mint and chrysanthemum can be helpful. However, if you have chills, runny nose, and body aches without much thirst, you likely have a wind-cold pattern, and these cooling herbs could make you feel worse. When in doubt, start with a simple, neutral food like congee or rice soup and consult a practitioner.
I have a very sensitive stomach. Which of these is the safest to start with?
Chrysanthemum tea is generally the gentlest. It’s mild, cooling without being harsh, and its sweet flavor is soothing to the digestive system. You can also try adding a single slice of fresh ginger to any of the teas to warm the middle burner and aid digestion, creating a balanced, harmonious drink.
How often can I drink these teas? Is it okay every day?
For most people without underlying health conditions, drinking 1-2 cups of one of these teas daily during a heatwave is perfectly fine and can be quite beneficial. Listen to your body. If you start feeling chilly in an air-conditioned room or notice your digestion becoming loose, it’s a sign to reduce the frequency or switch to a less cooling option. The goal is balance, not to turn yourself into a refrigerator. Rotate between them based on your symptoms—mint for headaches, chrysanthemum for eyes, mung bean for overall heat.
The bottom line: Summer cooling isn’t about blasting the AC and drinking ice water—it’s a subtle, ancient art of using your kitchen to restore balance. By incorporating these five cooling herbs and foods—mint, chrysanthemum, mung bean, licorice root, and winter melon—you can create simple, potent remedies that address the specific discomforts of the season, from headaches and eye strain to puffiness and internal heat. Start with one that matches your primary symptom, prepare it with intention, and notice how your body responds. This is mindful eating at its most practical and powerful.
