At a glance
Duzhong leaf tea uses leaves of Eucommia ulmoides, distinct from bark, seed oil or male flowers. Choose a labelled finished leaf product and its complete preparation rather than transfer a medicinal bark claim to a cup.

Taste and appearance
The old table describes tight curled fine leaf material, glossy dark colour, clear orange-yellow to bright yellow liquor, fresh fragrance and a slightly bitter substantial taste with a long sweet finish. The lower comparison permits fragments. Its old thin serrated-leaf description is retained only as a comparison, not a botanical identification key. Original cup and material pictures remain contextual, without a measured nutrient or compound analysis.
The cover is the original material illustration. These images are not TeaPlain tasting samples or proof of origin, grade, age, authenticity or image rights clearance.
Grade characteristics
This preserves the earlier Chinese edition’s sensory comparison. It is not a complete verified current standard table and does not grade your packet. Plant material, growing area, processing and grade are separate details. Decorative star rankings are omitted.
On a small screen, scroll the table sideways to compare the grades.
| Feature | Extra grade (old comparison) | Grade 1 (old comparison) |

| Aroma | Fresh fragrance | Fresh fragrance |
| Taste | Slightly bitter substantial mellow cup with long sweet return | Slightly bitter fairly mellow fresh cup |
| Infused material | Fine thin tender leaves with serrated edges | Thin tender even leaves |
These inherited comparisons are not a complete verified current product standard. Appearance and cup colour cannot authenticate plant identity, source, purity or food suitability.
Names and origin
The 2023 Chinese announcement and its attachment identify Eucommia ulmoides leaves among newly listed traditional food/medicinal materials; that does not make all parts interchangeable or certify every marketed product. A separate producer’s actual product specifies 100% Eucommia leaves and its own preparation, independently supporting the leaf-versus-bark distinction. The old silianpi/chesipi names concern bark associations and are not used as synonyms for the leaf ingredient. Old amino-acid/mineral assertions are not a measured nutrient value for this infusion, and fermentation is not established for all commercial styles.
Everyday benefits
An unsweetened, clearly identified food-grade infusion can be enjoyed for flavour and as an alternative to a sweetened drink. The earlier therapeutic claims are not established for this cup. It is not a treatment or a substitute for food or prescribed care.
Who may enjoy this tea
For people who enjoy a clearly identified slightly bitter leaf drink with returning sweetness, subject to its ingredients and label. It is not a blood-pressure, sleep, liver/kidney or weight-loss treatment.
When to take care
The Chinese interpretation of the 2023 additions does not recommend these materials for pregnant or breastfeeding readers or infants/young children. Check the actual product with a professional if you have medical conditions or use medicines; this is not permission to replace blood-pressure or kidney care. If taking medicines or Iron supplements, follow their instructions and ask a pharmacist about the actual product rather than assume that all herbal drinks have the same interactions. Pregnancy, breastfeeding, allergies and suitability for children need the identified ingredients and preparation; this page gives no medicinal dose.
How to brew
Original prose: glass or porcelain cup
The inherited method uses a heat-safe glass or porcelain cup, 1:50, 90–100°C / 194–212°F water, refilling at about one-third remaining and roughly three infusions. It gives no first steeping time. For an identified food-grade product only, an arithmetic example is 3 g with 150 mL Actual water; that is not a dose validated for every herb. Follow the complete packet instructions first. Different plant species, plant parts and processing cannot share one universal recipe.
These inherited directions are awaiting hands-on testing. Refilling changes the concentration and is not a new measured batch. Let the drink cool enough to sip; do not use a photograph to identify unknown plants.
Read the original illustration separately
Illustration: cup. Add 5–10 g Eucommia leaf, 80°C / 176°F hot water, wait 3–5 minutes, repeat infusions as desired. It gives no Actual water volume, vessel capacity or fixed repeat count. This is distinct from the old prose’s 1:50/90–100°C. It is not a medicinal daily dose and is not interchangeable with a manufacturer’s separately tested boiling method.
For ordinary teaware options, see brew without a gaiwan. Keep each complete method together instead of selecting temperature, dose and time from different preparations.
Adjust your cup
Identify the ingredients and follow the actual food product’s complete preparation instructions first. Once that is clear, adjust within those directions for taste. Do not increase the dose or boiling time of unknown plant material to make it suitable for drinking.
How to buy
Check Eucommia leaf identity, plant part, food-use label, processed style, full ingredients, maker, dates and instructions. A compound claim or a bark-related trade name does not validate a leaf product.

China price reference
Undated figures retained from the Chinese edition, in Chinese yuan (CNY). No original brand, batch, harvest or quotation date was recorded. These are not verified current retail quotes, a market average or manufacturer-suggested retail prices.
| Chinese-edition tier | CNY per 500 g (one jin) | Equivalent CNY per 100 g |
|---|---|---|
| Extra grade | 700 | 140 |
| Grade 1 | 450 | 90 |
Per 100 g is an arithmetic conversion, not a quoted packet. Do not infer a missing sensory or price tier. Compare actual growing area, style, harvest, roast, weight and channel. A currency conversion does not make a UK or US retail offer comparable to a China historical figure.
How to store
Original storage method
Protect the product from sun and rain and store in a ventilated dry place, separately from toxic or harmful substances and strong smells. The source gives 18 months under those conditions; this is an undated source-specific claim, not a shelf life for every Eucommia product. Keep the actual package closed as directed and use its printed dates. Protect from kitchen steam and moisture; do not store a wet infusion using these dry-product instructions.
Origin, processing and history
The inherited chart labels withering, rolling, fermentation and drying. It illustrates one claimed processed style rather than a verified manufacturing sequence for every Eucommia leaf product. It does not describe bark, seed oil or flowers.
Common questions
Can I substitute duzhong bark for the leaf tea?
No such substitution follows from the shared plant name. Leaves, bark, male flowers and seed oil are different materials with different uses and conditions. Identify the finished product and follow its label.
Can I move one number from this recipe into a different vessel?
Keep leaf form, measured dose and actual water, temperature, timing and separation together. Nominal capacity or a fill fraction is not a measured ratio.
