There’s a particular kind of heat that settles into your bones by late July. It’s not just the air temperature; it’s a feeling of being slightly overcooked from the inside out. Your skin feels tight, your mind feels foggy, and your energy seems to evaporate before noon. In Traditional Chinese Medicine (TCM), we don’t just say “it’s hot outside.” We say the Summer’s Yang energy, which is expansive and active, can become excessive and disrupt our internal balance, leading to what we call “Summer Heat” or Shu Re. The remedy isn’t always to blast the AC; it’s to invite a gentle, cooling counterbalance into our bodies from the inside. And the most accessible place to find that balance is often right in your own kitchen spice rack.
Why “Cooling” Doesn’t Mean “Cold”: Understanding Thermal Nature in Food
Before we dive into the herbs, let’s clear up a common misconception. In Western thinking, “cooling” foods are often just those served chilled—like a salad straight from the fridge. In TCM, the concept of a food’s thermal nature is far more nuanced. It’s not about its physical temperature when you eat it, but its inherent energetic effect on your body after digestion.
Think of it like this: A jalapeño pepper is physically at room temperature, but eat one and you’ll feel heat radiating from your mouth and scalp. That’s a “hot” food. Conversely, a watermelon, even if left in the sun, has a “cool” nature—it helps clear heat and generate fluids. This is the principle of Si Qi (the Four Natures): hot, warm, cool, and cold. Cooling herbs and foods help to clear internal heat, calm inflammation, and promote hydration. They are the gentle rain to the summer sun’s blaze.
My grandmother had a wonderful way of putting it. On sweltering days, she’d never say, “Don’t drink cold water.” Instead, she’d say, “Your stomach is a gentle fireplace. Pouring ice on it puts out the flame and makes everything damp and sluggish. Instead, add a cooling wood to the fire—something that calms the blaze without extinguishing it.” This is the wisdom of using cooling herbs: they work with your body’s own systems to restore equilibrium.
The Cooling Quintet: Your 5 Kitchen All-Stars
You likely have most of these already. The key is knowing how to use them not just for flavor, but for their specific cooling properties.
1. Fresh Mint (Bo He)
Mint is the poster child of cooling herbs. Its volatile oils, especially menthol, provide an immediate sensation of relief. In TCM, mint is prized for its ability to “release the exterior”—meaning it helps push out the invading heat from the surface of your body, particularly through the skin. It’s fantastic for the heat headache, the slight fever, or the general feeling of being “stuck” in the heat.
- Actionable Use: Don’t just brew a tea. For a powerful cooling effect, steep 1 large handful of fresh mint leaves (about 15-20 leaves) in 2 cups of just-boiled water for only 3-4 minutes. Any longer and you lose the volatile oils. Drink it warm, not iced, to encourage a gentle sweat that will actually cool you down faster.
- Quick Fix: Feeling overheated and headachy? Muddle 5-6 mint leaves in the bottom of a glass, add a squeeze of lime, top with sparkling water, and drink it immediately.
2. Chrysanthemum (Ju Hua)
If mint is for the body’s surface, chrysanthemum is for the heat rising to the head and eyes. This delicate flower is a cornerstone of summer wellness in China. It specifically targets what we call “Liver Fire Rising”—a pattern of heat that manifests as red, irritated eyes, a throbbing headache (especially behind the temples), irritability, and dizziness. It’s the perfect antidote for screen fatigue on a hot day.
I remember my father keeping a large glass jar of dried chrysanthemum flowers and rock sugar on his desk every summer. He’d brew a big pot in the morning, and we’d all sip it throughout the day. It wasn’t just a drink; it was our family’s preventative medicine against summer grumpiness.
Actionable Use: For a classic, balancing brew, use 8-10 dried chrysanthemum flowers and 2-3 small pieces of rock sugar (or a teaspoon of honey) per cup. Steep in hot water for 5-7 minutes. The sweetener isn’t just for taste; in TCM, it helps “guide” the herb’s cooling properties to the right places and protects the stomach.
3. Green Onion / Scallion (Cong Bai)
This one surprises people. The white part of the green onion is a potent, yet gentle, cooling and releasing agent. It’s particularly useful at the very first sign of a summer cold—the kind where you feel a slight chill, maybe a scratchy throat, and then get hit with a fever. It helps your body “sweat out” the pathogen, a process we call releasing the exterior.
Actionable Use: The classic remedy is “Cong Chi Tang” (Green Onion and Fermented Soybean Soup). It’s simple: Take 3-4 green onions, using only the white and light green parts, sliced. Add them to a bowl with 2 tablespoons of fermented black beans (dou chi, found in Asian markets). Pour 2 cups of boiling water over them, cover, and let steep for 10 minutes. Drink the warm broth, get under a light blanket, and prepare to gently perspire. This is most effective at the very onset of feeling “off.”
4. Mung Bean (Lü Dou)
Mung beans are the ultimate detoxifier of Summer Heat in TCM. They are sweet and cooling, and they have a special affinity for clearing heat from the blood and promoting urination, which is a primary way your body flushes out toxins and excess heat. They’re not just for sprouts; the whole bean is a summer superfood.
Actionable Use: Make a simple, sweet mung bean soup. Rinse 1 cup of dried mung beans and soak them for 2 hours. Drain, add to a pot with 6 cups of water, and bring to a boil. Reduce heat and simmer for 45-60 minutes until the beans are soft and starting to break down. Add a small piece of rock sugar or a tablespoon of honey to taste. Drink it warm or at room temperature. A small bowl daily during a heatwave is profoundly preventative.
5. Cucumber (Huang Gua)
Yes, a cucumber is technically a fruit, and in the TCM kitchen, it’s a first-rate cooling herb. It’s 95% water, but its cooling nature goes beyond simple hydration. It helps clear heat, quench thirst, and reduce irritability. The key is to eat it at room temperature or slightly cool, not ice-cold, to protect your Spleen Qi (your digestive fire).
Actionable Use: Move beyond salads. For a deeply cooling and hydrating drink, blend one whole peeled cucumber with 1 cup of water, a tablespoon of fresh lime juice, and a few mint leaves. Strain it if you like, and drink it within 30 minutes to preserve its vitality. This is far more effective than a sugary sports drink for replenishing fluids.

A Final Word: Balance is the Goal
“The wise nourish life by following the seasons. In summer, one must accommodate the joy and be outward, but also guard against the heat that scorches.”
— Huangdi Neijing (The Yellow Emperor’s Classic of Internal Medicine)
Using these cooling herbs isn’t about creating an arctic environment inside your body. It’s about listening to the signals—fatigue, irritability, headaches—and responding with gentle, intelligent nourishment. The goal is to enjoy the vibrant, active energy of summer without being depleted by it. A cup of chrysanthemum tea in the afternoon, a mung bean soup a few times a week, a sprig of mint in your water—these are small, profound acts of self-care that align you with the season’s rhythm.
So, next time the heat feels like too much, don’t just reach for the thermostat. Walk to your kitchen. Your secret weapon for summer balance is probably already waiting for you, in a jar, a bunch, or a bag.
Common Questions
Can I use these herbs if I have a “cold” constitution and am always chilly?
Absolutely, but with mindfulness. If you run cold, focus on the herbs that are cool rather than cold, and always consume them at room temperature or warm. Mint and green onion are excellent choices because they are pungent and help move energy. Avoid large quantities of mung bean soup or cucumber juice on their own; instead, add a few slices of fresh ginger to your chrysanthemum tea or mung bean soup to gently warm the formula and protect your digestion.
How often should I drink these teas or soups during a heatwave?
For general prevention, 1-2 cups of mint or chrysanthemum tea per day, or a small bowl (about 1 cup) of mung bean soup 3-4 times a week, is perfect. If you are actively experiencing heat symptoms (like a headache or irritability), you can safely have 2-3 cups of the appropriate tea throughout the day until symptoms improve. Listen to your body—if you start feeling cold or your digestion becomes sluggish, scale back.
Are there any people who should avoid these cooling herbs?
Yes, a few considerations: 1) If you are pregnant, consult a healthcare provider or a trained TCM practitioner before using any medicinally. 2) If you have severe digestive weakness (constant loose stools, bloating, fatigue), avoid large amounts of raw cucumber and be cautious with very cold preparations. Always consume cooling foods at room temperature. 3) If you are on blood-thinning medications, discuss regular use of large amounts of mint with your doctor, as it can have mild anticoagulant properties.
The bottom line: Your kitchen holds a powerful pharmacy for summer wellness. By understanding the cooling nature of common herbs like mint, chrysanthemum, green onion, mung bean, and cucumber, you can directly combat Summer Heat, soothe irritability, and restore your body’s natural balance. These are not just ingredients; they are time-tested tools for mindful, seasonal living.
