Summer arrives, and suddenly your kitchen feels like a furnace. The last thing you want is a steaming bowl of ginger soup or a sprinkle of warming cinnamon on your morning oatmeal. You crave something light, something that cools you from the inside out. But here’s a secret my mother taught me while we sliced cucumbers on sweltering August afternoons: the most powerful cooling agents aren’t always in the refrigerator. Sometimes, they’re already sitting in your spice rack, waiting for you to use them in a different way. This isn’t about adding ice to everything. It’s about understanding a core concept in Traditional Chinese Medicine (TCM) called thermal nature—the inherent temperature of a food or herb that affects our body’s internal climate, independent of its actual temperature. A chilled peppermint tea is cooling not just because it’s cold from the fridge, but because mint itself has a cooling nature that helps disperse heat and clear summer irritability. Let’s explore five common spices you already own that can help you harness this principle and turn your summer kitchen into a sanctuary of balance.
- 1. Mint (Bo He): The Instant Cool-Down
- 2. Cilantro / Coriander (Xiang Cui): The Dual-Purpose Cooler
- 3. Chrysanthemum (Ju Hua): The Flower That Cools Your Eyes and Mind
- 4. White Pepper (Bai Hu Jiao): The Surprising Summer Spice
- 5. Green Tea (Lü Cha): The Antioxidant Cooler

1. Mint (Bo He): The Instant Cool-Down
If there’s one herb that embodies summer cooling, it’s mint. In TCM, peppermint (Mentha piperita) and spearmint (Mentha spicata) are classified as acrid and cool. This means they have a dispersing, upward-moving quality that literally helps “ventilate” the body, releasing trapped heat through the pores. Think of it as opening a window in a stuffy room. My grandmother would hang bundles of fresh mint near the kitchen door in June. “For guests who come in flushed from the sun,” she’d say, “so we can offer them a drink that works from the tongue to the toes.”
The science aligns with the tradition. Menthol, the active compound in mint, triggers cold-sensitive receptors in your skin and mouth (the same ones that respond to actual cold temperatures), creating a genuine sensation of cooling. This isn’t just psychological—it can lower perceived body temperature and may even slightly reduce skin temperature.
How to Use It Today:
- The 2-Minute Cooling Infusion: Don’t boil mint to death. Steep 10-12 fresh leaves (or 1 teaspoon dried) in 8 oz of water that’s just off the boil (around 175°F/80°C) for only 2-3 minutes. Over-boiling releases bitter compounds and diminishes the cooling volatile oils.
- Savory Application: Chop fresh mint and fold it into a yogurt sauce with cucumber and a pinch of salt. Serve alongside grilled lamb or chickpeas. The mint cools the “heat” of the protein, according to food-combining principles.
- Unexpected Move: Add 5-6 fresh leaves to a pitcher of water with slices of cucumber and lemon. Let it sit in the sun for 30 minutes (a “sun tea”). The gentle infusion creates a profoundly refreshing drink that hydrates and cools simultaneously.
2. Cilantro / Coriander (Xiang Cui): The Dual-Purpose Cooler
This is the herb people love or hate, but its cooling properties are undeniable. What’s fascinating is that the leaves (cilantro) and the seeds (coriander) have similar but distinct actions. Both are cooling in nature, but the fresh leaves are more potent for releasing exterior heat—think of heat rashes, summer colds with sore throats, or that feeling of being overheated and slightly nauseous. The seeds are gentler, often used for cooling the digestive tract and alleviating “damp heat” like summer bloating or urinary discomfort.
“Cilantro is like a gentle breeze that clears the kitchen smoke. It doesn’t overpower; it just makes the air breathable again.”
A personal story: My uncle, a farmer, would chew on a few fresh cilantro leaves after a long day in the fields to prevent heatstroke headaches. He claimed it worked better than any commercial drink because it “told his body the sun was gone.” Modern research shows cilantro has potent antioxidant and anti-inflammatory effects, and some studies suggest it may help chelate heavy metals from the body—a bonus for overall detoxification, which is crucial in summer when our systems are already taxed.
How to Use It Today:
- Post-Meal Digestive Cooler: Crush ½ teaspoon of whole coriander seeds between your teeth after a spicy or greasy summer meal. Sip warm water with it. This can soothe the stomach and counteract the “internal fire” from heavy foods.
- Cooling Pesto Twist: Make a traditional pesto but replace half the basil with fresh cilantro leaves. Use it on cold pasta salads or as a dip. The basil is slightly warming, but the cilantro brings it back to a neutral-cool balance, perfect for summer.
- Topical Soother: For heat rashes or insect bites, make a paste by mashing fresh cilantro leaves with a tiny amount of water. Apply to the affected area for 15-20 minutes. The cooling and anti-inflammatory properties can provide quick relief.
3. Chrysanthemum (Ju Hua): The Flower That Cools Your Eyes and Mind
This might be the most surprising entry for a Western kitchen. Dried chrysanthemum flowers are a staple in Chinese households, especially in summer. Classified as sweet, bitter, and slightly cool, they are famous for two things: clearing heat from the head and eyes, and calming an agitated mind. Ever feel your eyes burning after too much screen time on a hot day? Or get a summer headache that feels like pressure behind the forehead? That’s the “rising heat” that chrysanthemum targets.
In TCM theory, summer corresponds to the Heart and Fire element. Excess heat can easily disturb the Heart, leading to anxiety, insomnia, and irritability. Chrysanthemum tea is a classic remedy to “calm the Shen” (the spirit or mind). My mother would brew it with goji berries (gou qi zi) for my father, who worked long hours under fluorescent office lights. “For the computer eyes and the busy mind,” she’d say. The combination is synergistic: chrysanthemum clears heat, and goji nourishes the Yin (cooling, moistening fluids) that the eyes depend on.
How to Use It Today:
- The Classic Duo Tea: Place 6-8 dried chrysanthemum flowers and 1 tablespoon of dried goji berries in a mug. Pour 12 oz of hot water (just under boiling) over them. Let steep for 5-7 minutes. The goji berries will plump up. Drink this in the afternoon to combat the 3 PM energy slump and eye strain.
- Chrysanthemum “Cool” Simple Syrup: Make a syrup by simmering 1 cup of water with ½ cup of sugar and ¼ cup of dried chrysanthemum flowers for 15 minutes. Strain and cool. Use 1-2 teaspoons in iced tea, sparkling water, or even drizzled over fresh fruit salad for a cooling, aromatic twist.
- Eye Compress: After drinking your tea, save the soaked flowers. Let them cool to room temperature, then place them gently over your closed eyelids for 10 minutes. It’s a simple, cooling compress for tired, puffy eyes.
4. White Pepper (Bai Hu Jiao): The Surprising Summer Spice
This is the most counterintuitive item on the list. Pepper? In summer? Absolutely. But it’s crucial to distinguish between black pepper (which is warming) and white pepper. In TCM, white pepper is considered acrid and warm, but its key action is dispersing cold and dampness. In the peak of summer, we create a perfect storm for internal dampness: we eat cold foods (ice cream, salads, iced drinks), we live in air-conditioned environments, and we sweat, which depletes Yang (warming) energy. This can leave us feeling bloated, sluggish, and paradoxically, still hot on the outside while cold and damp on the inside.
White pepper gently warms the digestive center (the Spleen and Stomach in TCM) to help it metabolize fluids and prevent this damp accumulation. It’s not about adding fiery heat; it’s about stoking a small, efficient digestive fire so you can process the lighter, cooler summer foods without creating stagnation. Think of it as lighting a small pilot light in a damp, cool basement to prevent mold.
How to Use It Today:
- The Morning Sprinkle: Add a scant ⅛ teaspoon of ground white pepper to your morning eggs, avocado toast, or even a smoothie bowl. It blends surprisingly well into sweet-savory flavors and gives your digestion a gentle wake-up call.
- Cooling Soup Base: Make a simple summer broth: simmer vegetable scraps (carrot tops, celery ends, onion skins) in water for 30 minutes. Strain. Just before serving, stir in ¼ teaspoon of white pepper and a pinch of sea salt. Sip this warm (not hot) broth before your main meal to prepare your stomach without overheating you.
- Fruit “Spice”: Sprinkle the tiniest amount of white pepper on fresh pineapple or mango. The sweet, cooling fruit is balanced by the pepper’s ability to move dampness, and the flavor combination is electric.
5. Green Tea (Lü Cha): The Antioxidant Cooler
While not a “spice” in the traditional sense, green tea is the undisputed champion of summer beverages in Chinese culture. It is classified as cool in nature and bitter in flavor. The bitterness helps drain dampness and heat, while the coolness directly counteracts summer’s warmth. Unlike black tea (which is warming due to full oxidation), green tea is minimally processed, preserving its potent catechins (like EGCG) and its cooling properties.
The key is brewing temperature. Most Westerners brew green tea with boiling water, which scorches the leaves, releases excessive tannins (making it bitter), and destroys delicate compounds. For a truly cooling effect, brew it like the Chinese do: with water between 160-180°F (70-82°C). This results in a sweet, vegetal, profoundly refreshing liquor.
How to Use It Today:
- The Perfect Cup: Use 1 teaspoon of loose leaf green tea (Dragonwell or Sencha are great) per 8 oz of water. Heat the water until small bubbles form on the bottom of the kettle (about 170°F/77°C). Steep for 2-3 minutes only. Pour all the liquid out. Do not leave the leaves sitting in water, or it will become bitter.
- Cold-Brew for Maximum Cooling: Place 2 tablespoons of loose green tea in a pitcher with 4 cups of cold, filtered water. Refrigerate for 8-12 hours (overnight). Strain. This method extracts fewer tannins and more amino acids, resulting in an incredibly smooth, sweet, and deeply cooling tea with higher L-theanine (which promotes calm focus).
- Culinary Use: Use brewed and chilled green tea as the base for a salad dressing. Whisk 3 tablespoons of cold-brewed green tea with 1 tablespoon of rice vinegar, 1 teaspoon of honey, and 2 tablespoons of light olive oil. It’s fantastic on a watercress and pear salad.

Common Questions
Can I use these spices if I have a “cold” constitution already?
Yes, but with wisdom. If you naturally run cold (you’re always chilly, have pale lips, and crave hot drinks), you can still enjoy summer cooling spices, but use them in moderation and combination. For example, a cup of chrysanthemum-goji tea is gentler than pure chrysanthemum. A mint tea with a slice of fresh ginger can provide the cooling sensation while the ginger protects your digestive fire. Listen to your body—if a cooling drink makes you feel chilly or uncomfortable, reduce the amount or pair it with a neutral or slightly warming food.
Are there any spices that are truly “neutral” and safe for everyone in summer?
Several herbs occupy a “neutral” thermal nature, meaning they won’t significantly push you toward hot or cold. These are fantastic summer staples. Key examples include licorice root (Gan Cao)—excellent for harmonizing other herbs and soothing digestion—and lotus leaf (He Ye), which is famous for clearing summer heat and dampness without being overly cold. You can find lotus leaf tea in most Asian grocery stores. A neutral sweet potato or a bowl of well-cooked rice is also a safe, grounding base for any summer meal.
I see “cooling” spices like peppermint sold in essential oil form. Is that the same?
No, and caution is essential. Essential oils are highly concentrated and not equivalent to the whole herb used in food or tea. Ingesting essential oils can be toxic and irritating to the mucous membranes and liver. The cooling effect of mint in tea comes from a complex array of compounds gently extracted in water. For kitchen use, stick to fresh or dried herbs. Essential oils can be used topically for cooling (e.g., diluted peppermint oil on the temples), but that is a different modality with different safety rules. Never take essential oils internally unless under the direct guidance of a qualified clinical aromatherapist.
The bottom line: Your summer cooling toolkit is likely already in your pantry. By understanding the thermal nature of common spices like mint, cilantro, chrysanthemum, white pepper, and green tea, you can move beyond simple refrigeration and actively create internal balance. Start with one—brew a proper cup of green tea or make a mint-infused water today—and notice how your body responds. This is the art of seasonal eating: not following rigid rules, but learning to listen and adjust with the wisdom of nature.
