1. Tea as medicine in TCM

Tea (cha) has been a part of Chinese medicine for at least 2,000 years and is older as a medicine than as a beverage. The earliest Chinese references to tea describe it as a remedy — an antidote to poisons, a digestive support and a clarifier of the senses — long before it became the everyday drink it is today. Tea retains this dual role in modern China: it is at once an ordinary social beverage, a refined cultural art form, and a precise therapeutic agent within the framework of Chinese food therapy.

Different teas and infusions have specific therapeutic actions, each suited to particular constitutions, seasons, conditions and times of day. Green tea clears heat and is suited to summer and damp-heat patterns; black tea is warming and supports yang; pu-erh resolves damp from rich meals; oolong descends Stomach qi and supports metabolism; chrysanthemum cools the Liver and brightens the eyes; goji nourishes Liver yin and blood. Drinking the right tea at the right time is one of the simplest, most widely applicable forms of Chinese food therapy — one that integrates effortlessly into a modern lifestyle.

2. A brief history of Chinese tea

Tea is native to the borderland between Yunnan, northern Burma and Assam — the original homeland of Camellia sinensis. Cultivation in China is documented from at least the Han dynasty (206 BCE–220 CE), but the first comprehensive treatment of tea is the Cha Jing (Classic of Tea) by Lu Yu, written around 760 CE during the Tang dynasty. Lu Yu's three-volume work codified the production, brewing and aesthetics of tea and is recognised as the first monograph on the subject in any culture.

The Tang dynasty drank tea as compressed cakes broken and boiled in pots; the Song dynasty whisked powdered tea into a froth (the parent of Japanese matcha); the Ming dynasty (1368–1644) introduced the modern method of steeping loose leaves in hot water, which has been the predominant Chinese style ever since. The development of partial oxidation in the late Ming and early Qing dynasties produced oolong; gradual fermentation in storage produced pu-erh; controlled bruising and full oxidation produced black tea (called "red tea" / hong cha in China).

Through the Tea-Horse Road (Cha Ma Gu Dao), Chinese pressed tea travelled to Tibet, Mongolia, Persia and Russia, becoming the staple of populations whose meat- and dairy-heavy diets needed digestive support. Through the maritime Silk Road and later the Dutch and British East India trade, tea became the global beverage it is today.

3. The six categories of Chinese tea

Modern Chinese tea is classified into six families based on processing method and degree of oxidation, each with characteristic colour, flavour and TCM action:

Beyond the six true tea categories are the flower and herbal infusions (hua cha when including blossoms, often grouped with herbal teas) which are technically not teas but are used in the same way: chrysanthemum, rose, jasmine, osmanthus, goji-chrysanthemum, red-date-ginger and Eight Treasures tea all sit in this category. These caffeine-free infusions form the bulk of medicinal Chinese tea use.

4. TCM properties of the major teas

Each tea family has a distinct TCM signature:

Green tea (lu cha)

Cool to cold, bitter and slightly sweet; enters Heart, Lung and Stomach channels. Clears heat, descends fire, resolves damp-heat, alerts the mind. Best suited to damp-heat constitutions, summer drinking, and after-meal use to reduce greasiness. Avoid in cold-pattern stomach problems and in winter for cold constitutions.

Black tea / red tea (hong cha)

Warm, sweet and slightly bitter; enters Spleen, Stomach and Heart channels. Warms the middle, tonifies yang gently, supports digestion. Best for cold mornings, cold constitutions, mild yang deficiency. Avoid in yin-deficient heat patterns and damp-heat.

White tea (bai cha)

Cool, sweet and slightly nutty; enters Lung and Stomach channels. Clears heat gently without being chilling. The most delicate of teas. Good for tea drinkers with sensitive stomachs and for hot weather. The aged-white tradition (white tea aged 3+ years) becomes more warming.

Oolong (wulong cha)

Neutral to slightly warm, depending on roast and oxidation. Descends Stomach qi, supports digestion of fats, balanced for daily use across constitutions. The most versatile of the true teas. See the oolong page for full detail.

Pu-erh (pu er cha)

Warm to neutral, bitter and slightly sweet; enters Spleen, Stomach and Liver channels. Resolves food stagnation, descends rebellious qi, transforms damp, reduces lipid and fat accumulation. The classic after-rich-meal tea. See the pu-erh page for full detail.

Chrysanthemum (ju hua)

Cool, sweet-bitter-pungent; enters Lung and Liver channels. Clears wind-heat, calms Liver yang, brightens the eyes. Caffeine-free. Used alone or in blends with goji.

Goji berry tea (gou qi zi)

Neutral, sweet; enters Liver, Kidney and Lung channels. Tonifies Liver and Kidney yin and blood, brightens the eyes, moistens the Lung. Caffeine-free, safe for daily long-term use. See the goji-chrysanthemum page.

Red date and ginger (hong zao jiang cha)

Warm, sweet-pungent; enters Spleen, Stomach and Heart channels. Tonifies qi and blood, warms the middle, harmonises. The classic Chinese women's warming tonic. See the red date and ginger tea page.

Eight Treasures tea (Ba Bao Cha)

Slightly warm overall; sweet and aromatic. The composite tonic blend of northwest China. Tonifies qi and blood, calms the spirit, supports the eyes. See the Eight Treasures tea page.

5. Choosing tea by condition

6. Choosing tea by constitution

Constitution is one of the strongest determinants of which tea suits you. See the nine TCM body constitutions page if you are unsure of yours.

7. Brewing principles

Across all Chinese teas, certain principles produce the best cup:

1. Use good water. Filtered or spring water is preferred. Hard tap water dulls flavour and creates a film on the surface (calcium binding to tea polyphenols).
2. Match water temperature to tea type:
   • Green and yellow tea: 75–85°C (full boil bitters them)
   • White tea: 75–85°C
   • Light oolong: 85–95°C
   • Dark oolong, black tea, pu-erh: 95–100°C
   • Floral and herbal: 80–90°C (full boil destroys delicate aromatics)
3. Rinse the leaves for compressed pu-erh, dense oolongs and aged teas: pour over hot water, count to 5, discard. This wakes the leaves.
4. Use generous leaf, short steep, multiple infusions — the gongfu way. Same leaves brewed 5–10 times reveal evolving flavours and extract more therapeutic compounds in total than a single Western steep.
5. Drink while warm. Tea cools quickly; cold tea loses both flavour and TCM action. Reheat gently rather than drinking cold.
6. Drink between meals for general use; drink after meals for digestion-supportive teas (pu-erh, oolong); drink in the morning for tonifying teas.

Vessels

1. Gaiwan (covered porcelain cup with saucer) — the most versatile traditional vessel; suits all tea types.
2. Yixing teapot (unglazed clay) — absorbs and concentrates flavour over time; reserved for one tea type per pot.
3. Glass teapot — ideal for visual teas: goji-chrysanthemum, Eight Treasures, white tea.
4. Mug with infuser — the everyday Western alternative; works for all teas though aroma is less concentrated.

9. General cautions

1. Caffeine: all true teas (green, white, yellow, oolong, black, pu-erh) contain caffeine. Limit total caffeine to under 200mg per day in pregnancy. Avoid late evening if caffeine-sensitive.
2. Iron deficiency: tea tannins reduce non-haem iron absorption. Drink between meals, not with iron supplements or iron-rich plant meals.
3. Dehydration myth: tea is not significantly dehydrating at normal drinking quantities — modern research has overturned the older belief that tea acts as a diuretic.
4. Anticoagulants: tea polyphenols and goji have mild blood-thinning effects. Discuss with your prescriber if you are on warfarin or other anticoagulants.
5. Acid reflux: stronger teas can aggravate reflux in some people; reduce strength or switch to a lighter category.
6. Tea on an empty stomach: strong tea (particularly pu-erh and oolong) on an empty stomach can produce nausea, lightheadedness and tremor in some people. Drink with or after food.
7. Children: avoid caffeinated tea for children under 12. Caffeine-free goji-chrysanthemum and weak red date are appropriate.
