🌱 Tea Plant Nutrition and Health Benefits: What to Know

Tea plant nutrition and health benefits start with a healthy Camellia sinensis plant and a well-brewed cup. Tea provides beneficial plant compounds, but it isn’t a cure-all; the most dependable everyday perk may be enjoying a flavorful, low-calorie drink instead of a sugary one.

At Growing Teas™, we’ve learned that a yellow leaf can spark a fertilizer hunt, but the real culprit may be sogy roots or soil that’s too alkaline. In the cup, too, the details matter: green, black, white, and olong tea all come from the same plant, while processing changes their character.

So what deserves your attention: the nutrients in the soil, the compounds in the brew, or the claims on the tea tin? We’ll sort the garden facts from the wellness hype—and help you get more from both your tea plant and your teapot.

Key Takeaways

• Tea comes from Camellia sinensis. Green, black, white, olong, and pu-erh teas are processed differently; herbal infusions come from other plants.
• Healthy tea plants need acidic, well-drained soil, steady moisture, and balanced feeding. Test the soil before adding fertilizer.
• Plain brewed tea is low in calories and contains plant polyphenols; caffeine levels vary by tea and brewing method.
• Research suggests possible health associations, not guaranteed benefits. Tea can complement healthy habits, but it does not replace treatment or medication.
• Mind the cautions: caffeine may affect sleep, tea can reduce absorption of plant-based iron, and very hot drinks should be allowed to cool.
• For homegrown tea, harvest lightly from established plants and process leaves carefully for safe, enjoyable brewing.

⚡️ Quick Tips and Facts

• “Tea plant” means Camellia sinensis. Green, black, white, olong, and pu-erh tea all come from this plant; their differences mainly reflect how the leaves are processed. Chamomile, peppermint, and hibiscus are herbal infusions—not true tea.
• A plain 8-ounce cup of brewed tea has about 2 calories, but its caffeine and polyphenol content vary with the tea, leaf quantity, water temperature, and steeping time. Harvard’s Nutrition Source notes that tea is generally rich in polyphenols while providing few significant nutrients.
• Tea leaves need acidic, well-drained soil. Aim for about pH 4.5–6, steady moisture, and balanced feeding rather than a heavy dose of fertilizer. Our first rule in the garden: test the soil before reaching for the fertilizer bag.
• The same plant can yield green or black tea. The difference is processing: green tea is heated soon after picking to limit oxidation; black tea is rolled and oxidized.
• Tea may fit into a healthy routine, but evidence for specific disease-prevention claims is mixed. Tea is a beverage, not a treatment.
• Let freshly brewed tea cool before drinking. The International Agency for Research on Cancer classifies beverages consumed above 65°C (149°F) as probably carcinogenic, with the concern linked to heat rather than tea itself. IARC
• Want to grow your own? Start with a healthy plant, acidic soil, and patience. Tea plants are evergreen shrubs, not instant teabags. 🌱

🌱 Tea Plant Nutrition: What the Camellia sinensis Plant Needs

Tea plant nutrition has two meanings: what nutrients the living tea shrub needs to grow, and what nutrients or compounds end up in the cup you drink. The plant side comes first. If the roots are struggling in alkaline, waterlogged soil, no premium fertilizer will perform a miracle.

In our growing beds, we’ve learned to treat the soil like a pantry: keep it acidic, airy, and stocked in balance. Overfeeding can produce lush-looking leaves while making the plant more vulnerable to stress. And when leaves yellow or curl, nutrition isn’t always the culprit: common pests and diseases that affect tea plants can create similar symptoms.

For practical growing guidance, see our resources on green tea cultivation, fertilizers for tea plants, and organic farming techniques.

Essential nutrients for healthy tea plants

Like other plants, tea shrubs need macronutrients and micronutrients. Their proportions matter: a plant needs nitrogen, but that doesn’t mean “more nitrogen” is always better.

Nutrient	What it does for a tea plant	What a shortage may look like
Nitrogen (N)	Supports leafy growth and chlorophyll formation	Older leaves may pale or yellow; growth may slow
Phosphorus (P)	Supports roots, energy transfer, and establishment	Weak growth; symptoms can be subtle and soil-dependent
Potassium (K)	Helps regulate water movement and supports stress tolerance	Leaf-edge discoloration or poor vigor may occur
Magnesium (Mg)	Central component of chlorophyll	Yellowing between veins, often on older leaves
Calcium (Ca)	Supports cell walls and growing tissues	New growth may be distorted if deficiency is severe
Sulfur (S)	Helps form proteins and enzymes	General yellowing can resemble nitrogen deficiency
Iron (Fe)	Needed for chlorophyll production and other plant functions	Yellow young leaves with greener veins, especially in alkaline soil
Manganese, zinc, boron, copper, molybdenum	Needed in small amounts for enzyme activity and normal development	Symptoms vary; excess can also harm plants

These symptoms are clues, not diagnoses. For instance, iron can be present in the soil but unavailable to roots when the soil pH is too high. A yellow leaf does not automatically mean “add iron.” Check drainage, pH, root health, watering, and pests before changing the feed.

Tea plants are generally acid-loving shrubs. The University of Florida’s Camellia growing guide gives useful advice for related ornamental camellias; tea is also a camellia, though growing conditions and harvest goals differ.

How soil pH, drainage, and organic matter affect tea

For a home tea plant, the basics are more valuable than a complicated fertilizer schedule:

• Soil pH: Aim for roughly 4.5–6.0. A soil test gives you a better starting point than guessing from leaf color.
• Drainage: Tea roots need moisture, not a swamp. Use a pot with drainage holes and a loose, acidic medium.
• Organic matter: Mature compost or suitable leaf mold can improve soil structure. Keep it modest and well decomposed.
• Water: Water consistently, particularly in containers and during hot weather. Let excess water drain away.
• Mulch: A light layer of pine bark or other suitable organic mulch can help conserve moisture. Keep mulch away from the stem.
• Light: Bright, filtered light suits many young plants; established plants can tolerate more sun when acclimated and sufficiently watered.

A useful first step is checking the pH and texture of the growing medium. Our team has seen more than one plant blamed on “weak fertilizer” when the real problem was a pot that held water like a bathtub. If you’re growing other tea-related plants, our herbal tea planting guide covers plants such as mint and chamomile, which have different growing needs from Camellia sinensis.

Nutrient deficiencies and signs to watch for

Use this quick diagnostic sequence before fertilizing:

1. Look at which leaves are affected. Older leaves often show mobile nutrient deficiencies first; new leaves can show issues with less-mobile nutrients.
2. Check moisture and drainage. Both drought and waterlogged roots can cause yellowing, leaf drop, and weak growth.
3. Inspect the leaves closely. Look for stipling, webing, sticky residue, chewed edges, or lesions that may point to pests or disease.
4. Test the soil or poting medium. Check pH and, if possible, nutrient levels.
5. Feed only if the evidence supports it. Follow the product label, use a tea-appropriate fertilizer, and avoid applying concentrated fertilizer to a dry or stressed plant.

Don’t diagnose by color alone. Yellow leaves can result from pH, cold, overwatering, root damage, pests, or natural aging. The University of California’s plant nutrient deficiency guide explains why diagnosis needs context.

🍃 Tea Plant History, Origins, and Growing Regions

The tea shrub belongs to the genus Camellia. Two widely discussed forms are the smaller-leaved China type, Camellia sinensis var. sinensis, and the larger-leaved Assam type, var. assamica. Their descendants grow across a broad range of climates, from cool mountain slopes to warm, humid regions.

Tea has been cultivated for centuries, and its history is not a single tidy origin story. China, India, and other parts of Asia have long tea-growing traditions, with local cultivars, processing styles, and customs shaping what ends up in the cup. The Royal Botanic Gardens, Kew lists Camellia sinensis as a recognized species.

Growing conditions influence leaf size, harvest timing, aroma, and flavor. Climate and soil shape the plant; processing shapes the tea style. A garden-grown shrub may not produce the same profile as a high-elevation commercial tea, but fresh leaves can still make a rewarding cup.

🫖 Tea Nutrition Facts: What’s in a Cup?

Plain tea is low in calories and contributes plant compounds, but it is not a meaningful source of most vitamins or minerals. The minerals in a cup are usually present in small or trace amounts. Adding milk, sugar, honey, or syrup changes the nutrition substantially.

Beverage or ingredient	Typical nutrition note	What to keep in mind
Plain brewed tea	About 2 calories per 8-ounce cup in the WebMD nutrition summary	Caffeine and polyphenols vary by brew
Sugar or syrup	Adds sugars and calories	Sweetened bottled tea can differ greatly from plain tea
Milk or cream	Adds calories, protein, and sometimes fat	Taste and nutrition change with the amount used
Lemon	Adds flavor and a small amount of vitamin C	A squeeze is not a major nutrient source
Matcha	Powdered tea leaf is consumed rather than only an infusion	Contains more leaf material per serving than steeped tea

The USDA FoodData Central is useful for comparing specific products, but packaged tea drinks vary by recipe. Check the label: “tea” on the front does not guarantee a low-sugar drink.

Calories, caffeine, and key compounds

Caffeine is naturally present in traditional tea, but the amount changes with the leaf, serving size, water temperature, and steeping time. WebMD’s tea overview gives approximate figures of 47 mg per 8-ounce cup of brewed black tea and 28 mg for green tea; actual cups can land above or below those estimates. See WebMD’s tea overview and the FDA’s caffeine guidance.

Drink	Caffeine?	Main source
Black, green, white, olong, pu-erh	Usually yes	Camellia sinensis leaves
Decaffeinated tea	Usually a small amount remains	Processed Camellia sinensis
Chamomile, peppermint, hibiscus	Typically caffeine-free	Flowers, leaves, or calyces from other plants
Yerba mate	Yes	Ilex paraguariensis, not Camellia sinensis

“Herbal tea” is a broad everyday label for a tisane, or plant infusion. Harvard Health explains this distinction in its article on three herbal teas.

Catechins, theanine, and tea polyphenols explained

Tea contains polyphenols, a large family of plant compounds. Green tea is especially associated with catechins such as EGCG; black tea contains oxidation products including theaflavins and thearubigins. These compounds are studied for possible biological effects, but a compound showing activity in a laboratory does not prove that drinking tea prevents or treats disease.

Tea also contains L-theanine, an amino acid associated with tea leaves. Research has explored how it may interact with caffeine and attention, but results depend on study design, dose, and individual response. Harvard’s Nutrition Source tea overview reviews tea polyphenols and the limits of health evidence.

How green, black, white, olong, and pu-erh tea differ

All five can come from Camellia sinensis. Their color and taste reflect harvest and processing.

Tea type	Typical processing	Flavor profile
Green	Heated soon after harvest to limit oxidation	Fresh, vegetal, grassy, nuty, or sweet
White	Young buds or leaves receive relatively gentle processing	Delicate, floral, light
Oolong	Partially oxidized; methods vary widely	Floral to roasted, depending on style
Black	More fully oxidized before drying	Robust, malty, fruity, or brisk
Pu-erh	Traditionally made through distinctive microbial aging or processing	Earthy, mellow, and often complex

These are general patterns, not strict flavor promises. Cultivar, weather, harvest season, and craft all matter. For growing notes focused on the tea shrub and leaf harvest, visit Green Tea Cultivation.

💚 Potential Health Benefits of Tea

Tea’s best-supported everyday advantage may be simple: plain tea is a flavorful, low-calorie drink that can replace sugar-sweetened beverages. Research also associates regular tea drinking with several health outcomes, but association is not proof of cause and effect. People who drink tea may differ in other ways from people who do not.

Harvard’s Nutrition Source reports that observational studies have linked drinking around 2–3 cups a day with lower risks of some cardiovascular outcomes and type 2 diabetes, while emphasizing that stronger clinical evidence is needed. Read its evidence overview.

Heart health, cholesterol, and blood pressure

Some large observational studies have found associations between tea consumption and lower cardiovascular risk. For example, Harvard’s review summarizes a Japanese cohort of 82,369 adults in which drinking green tea was associated with lower stroke risk. That finding is interesting, but it cannot show that tea alone caused the difference.

Clinical trial findings on cholesterol and blood pressure are mixed and often modest. Some reviews report small changes in cholesterol with green or black tea; other analyses find no significant effect. Tea can be part of a heart-supportive routine, but it should not replace prescribed medication, blood-pressure monitoring, or medical advice.

Our practical recommendation: enjoy unsweetened tea if you like it, and think of it as one small part of a broader pattern that includes a balanced diet, movement, sleep, and not smoking.

Tea, brain health, focus, and mood

Caffeine can temporarily increase alertness, while the overall experience of a warm drink and a regular tea break can feel calming. Individual responses vary: one person’s bright-eyed morning cup is another person’s jittery 4 p.m. mistake.

Research has examined tea drinking and cognitive health, but observational findings do not prove that tea prevents dementia or other brain conditions. If caffeine affects your sleep or anxiety, try a smaller cup, a shorter steep, or a caffeine-free herbal infusion. For reputable general caffeine advice, consult the FDA.

Digestion, gut health, and metabolism

Tea is not a digestive cure or a reliable fat-loss shortcut. Some people find warm liquids soothing; others find caffeinated tea worsens reflux or stomach discomfort. Ginger infusion is often used for nausea, but evidence about ginger itself should not be treated as proof that every ginger tea product has the same effect. Harvard Health summarizes what is known about ginger tea and other herbal infusions.

Be skeptical of “detox” or “slimming” teas. Some products contain laxative ingredients, which can cause diarrhea, dehydration, or electrolyte problems. The National Center for Complementary and Integrative Health cautions that detox and cleanse claims are not well supported.

Immune health, inflammation, and antioxidants

Tea polyphenols are studied for antioxidant and anti-inflammatory activity. That science is promising, but it is easy to overstate: antioxidants in a test tube are not the same as a proven immune boost in a person. No tea can guarantee protection from infections or take the place of vaccination, medical care, or adequate nutrition.

Herbal infusions also vary by plant. Chamomile, ginger, and hibiscus are not nutritionally or medically interchangeable with true tea. Harvard Health describes potential benefits and cautions for ginger, chamomile, and hibiscus teas.

Bone, oral, and overall wellness

Tea contributes fluid, and unsweetened tea can be a useful alternative to sugary drinks. Some tea contains fluoride, but amounts vary; tea should not be treated as a substitute for dental care or a reliable fluoride supplement. Tea’s role in bone health is also still being investigated, and findings are not strong enough to recommend it as a treatment.

A balanced view is the most useful one: tea can be a pleasant part of a healthy routine, not a shortcut around one. For more evidence-based tea topics, explore Growing Teas™ Health Benefits of Tea.

⚠️ Tea Risks, Side Effects, and Who Should Be Careful

For most healthy adults, moderate tea drinking is generally considered a low-risk habit. The caveats are caffeine, very hot drinks, medication interactions, and concentrated supplements. Herbal products can also interact with medicines, even when they look gentle in a teacup.

Caffeine sensitivity, sleep, and anxiety

Caffeine can cause restlessness, a faster heartbeat, tremor, headache, anxiety, or difficulty sleeping. Sensitivity varies widely, and caffeine from tea still counts toward your total intake from coffee, energy drinks, chocolate, and supplements.

Try these adjustments if tea is making you feel wired:

• Choose a smaller serving or steep for less time.
• Switch to decaffeinated tea, recognizing that it may still contain a little caffeine.
• Keep caffeinated tea earlier in the day.
• Choose a naturally caffeine-free infusion such as peppermint or chamomile, after checking whether it is suitable for you.

The FDA notes that caffeine tolerance differs from person to person; see its caffeine consumer guidance.

Tea and iron absorption

Tea polyphenols can reduce absorption of non-heme iron, the type found in plant foods and iron-fortified products. If you have iron deficiency or have been told to increase iron absorption, ask your clinician or dietitian whether to separate tea from iron-rich meals or supplements.

This does not mean everyone needs to avoid tea with meals. The practical response depends on your iron status, diet, and medical advice.

Pregnancy, medications, and health conditions

If you are pregnant, breastfeeding, taking medication, or managing a health condition, check with a qualified health professional before using herbal teas regularly or in concentrated amounts. Herbal does not automatically mean harmless.

Examples of cautions highlighted by Harvard Health include:

• Ginger: may affect blood cloting and could interact with anticoagulant or antiplatelet medicines.
• Chamomile: may trigger allergic reactions, particularly in people sensitive to plants in the daisy family.
• Hibiscus: may interact with certain medicines, including some diuretics; seek professional advice.

See Harvard Health’s herbal tea overview for more context. Don’t stop prescribed medication or use tea as a substitute for treatment.

Brewed tea versus concentrated extracts

A cup of tea is not the same exposure as a capsule containing concentrated green tea extract. Supplements may deliver far higher doses of compounds and can have different risks. The NIH Office of Dietary Supplements discusses green tea and extract safety in its fact sheet for health professionals.

Use caution with supplements marketed for weight loss or detox. They may combine concentrated ingredients in ways that are difficult to assess from the label alone. If you are considering an extract, ask a clinician or pharmacist first.

🍵 How to Brew Tea for Flavor and Nutrition

A good cup is a balancing act between leaf quantity, water temperature, and steeping time. Too hot or too long can make some teas bitter; too cool or brief can leave them flat. We’ve brewed enough “why is this cup so angry?” tea to know that small adjustments matter.

Water temperature and steeping time by tea type

These are starting points, not laws. Follow the package guidance when it differs, especially for specialty teas.

Tea type	Starting water temperature	Starting steep time	Tip
Green	About 175–185°F (79–85°C)	1–3 minutes	Cooler water can soften bitterness
White	About 175–185°F (79–85°C)	2–5 minutes	Try a longer steep if it tastes too light
Oolong	About 185–205°F (85–96°C)	2–5 minutes	Many loose-leaf olongs can be steeped more than once
Black	About 200–212°F (93–100°C)	3–5 minutes	Shorten the steep if it turns harsh
Pu-erh	About 195–212°F (91–100°C)	2–5 minutes	Rinsing is common for some styles; follow the supplier’s method

Harvard’s tea guide suggests hot water around 210°F for black and olong and cooler water for green tea. Brewing advice varies because leaf size, tea style, and personal taste vary.

Loose-leaf tea, tea bags, and matcha

• Loose-leaf tea: Gives you control over leaf quantity and room for leaves to expand. Use an infuser or teapot and strain before drinking.
• Tea bags: Convenient and consistent. Their smaller particles may release flavor quickly, so watch the steep time.
• Matcha: Whisked powdered green tea. Because you consume the powder rather than just the infusion, it differs from steeped tea.
• Fresh homegrown leaves: Use correctly identified, unsprayed leaves and process them with care. Don’t assume garden leaves are ready to eat simply because the plant looks healthy.

For a first brew from your own shrub, start with a small batch. Record the leaf quantity, time, and temperature; changing one variable at a time makes it easier to learn what you like.

Adding milk, lemon, sugar, or honey

Additions are about preference, not virtue. A splash of milk can soften black tea; lemon can brighten the flavor; sugar and honey add sweetness. Harvard’s Nutrition Source notes that milk may reduce some measured antioxidant activity in certain studies, though a little milk does not make tea an unhealthy drink.

If you want to keep your cup low in added sugar:

• Try cinnamon, vanilla, or citrus peel for aroma.
• Brew a naturally fruity herbal infusion.
• Add sweetener gradually, tasting as you go.
• Check bottled tea labels for added sugars.

🌿 Growing Tea at Home: Soil, Feeding, and Harvesting

Growing tea at home is wonderfully satisfying—and slower than ordering a box of tea bags. Camellia sinensis is an evergreen shrub that needs the right conditions to establish and enough time to produce useful harvests.

Choosing a tea plant and the right growing conditions

Look for a healthy Camellia sinensis plant from a reputable nursery. The label should identify the species, not merely say “tea plant” without botanical detail.

Growing factor	Practical starting point
Light	Bright, filtered light for young plants; acclimate gradually to stronger sun
Soil	Acidic, organic-rich, and free-draining
Water	Even moisture, without standing water
Container	Drainage holes are essential; use an acidic poting mix
Climate	Protect young plants from severe cold, drying wind, and sudden exposure
Harvest expectation	Allow the shrub to establish before taking repeated leaf harvests

The exact cold tolerance depends on plant type, age, exposure, and local conditions. For container culture, a large pot gives roots room but is heavier to move. In-ground plants can establish more deeply but need a suitable climate and soil.

Fertilizing Camellia sinensis responsibly

Tea plants benefit from balanced, measured feeding during active growth, but the right product depends on your soil, poting mix, and local water. Use a fertilizer labeled for acid-loving plants or camellias, and follow its directions rather than guessing at a stronger dose.

A careful feeding routine:

1. Test first. Check soil pH and look for nutrient problems.
2. Choose an appropriate product. Avoid products intended for unrelated crops unless their label and nutrient balance suit your situation.
3. Apply during active growth. Avoid fertilizing a drought-stressed, waterlogged, or dormant plant.
4. Water as directed. Never leave concentrated fertilizer sitting against dry roots.
5. Watch the response. New growth should be steady, not unnaturally soft or scorched.
6. Reassess before repeating. More fertilizer is not automatically better.

Our fertilizer guidance is collected in Fertilizers for Tea Plants, alongside broader organic farming techniques. For related camellia care principles, see the University of Florida guide.

Pruning, harvesting, and processing fresh tea leaves

Traditional tea harvest often targets a tender shoot with two leaves and a bud, but your young home shrub needs time to build strength. Avoid stripping a small plant bare.

A beginner’s harvest-and-process sequence:

1. Harvest only healthy growth. Choose tender, clean shoots from an established plant.
2. Keep the batch small. A modest harvest is easier to process consistently.
3. Sort and inspect. Remove damaged or dirty leaves. Do not use leaves from plants treated with products not approved for edible crops.
4. Choose the style you want. Green tea is quickly heated to limit oxidation; black tea is rolled and oxidized before drying. Oolong falls between, with many styles.
5. Dry thoroughly and safely. Inadequately dried leaves can spoil. Use a reliable method and store only when fully dry.
6. Brew a test cup. Note the taste and adjust processing next time.

Home processing is a craft, and the first batch may taste more “garden experiment” than “mountain tea.” That’s normal. Keep good notes, and don’t serve a batch if it smells moldy or appears contaminated. For leaf-production background, see our green tea cultivation resources.

⚖️ Tea and Weight Management: What the Evidence Says

Plain tea is low in calories, so replacing a sugary drink with unsweetened tea can reduce added sugar intake. That’s a practical substitution, not a special fat-burning effect.

Research on tea or green tea extracts and weight loss has not established tea as a dependable weight-management treatment. Be cautious of products claiming dramatic results, especially teas that promise to “detox” or cause rapid weight loss. Laxative-driven scale changes are not fat loss and can be harmful.

A sensible approach:

• Choose unsweetened tea if you enjoy it.
• Treat sweetened café and bottled drinks as beverages with their own nutrition profile.
• Avoid relying on tea extracts for weight loss without medical guidance.
• Focus on sustainable eating, activity, sleep, and support from a qualified professional when needed.

Harvard’s tea evidence review likewise notes that evidence for tea as a weight-loss aid is limited.

🔎 Tea Health Trends, Claims, and What Research Really Shows

Tea marketing often leaps from “contains antioxidants” to “prevents disease.” Those are not equivalent claims.

Popular claim	What we can responsibly say
“Tea prevents cancer.”	Laboratory and animal studies are not proof of prevention in people; human findings are inconsistent.
“Green tea melts fat.”	Evidence does not support dependable weight loss from tea alone.
“Herbal tea is always safe.”	Herbs can cause allergies and interact with medications.
“More tea means more benefit.”	More caffeine or concentrated extracts can increase risk without guaranteeing benefit.
“Very hot tea is healthier.”	Very hot beverages can injure tissue; let tea cool to a comfortable temperature.
“Tea and herbal tea are the same.”	Traditional tea comes from Camellia sinensis; herbal infusions use other plants.

There is also a genuine difference between observational studies and clinical trials. Large cohorts can identify patterns over many years, but people choose their own diets, so other habits may explain some of the association. Randomized trials can test cause and effect more directly, but many tea trials are small, short, or use extracts instead of ordinary brewed tea. That is why the strongest recommendation remains modest: enjoy tea as a beverage, not as medicine.

✅ Practical Tips for Making Tea Part of a Healthy Routine

• Choose plain tea most often if your goal is a low-sugar drink.
• Match caffeine to your day. Try black or green tea in the morning and herbal or decaffeinated tea later if caffeine affects sleep.
• Brew to taste. Adjust steeping time before adding sugar to fix bitterness.
• Let it cool. Avoid drinking tea at scalding temperatures.
• Store dry leaves well. Keep tea in an airtight container away from light, heat, moisture, and strong odors.
• Check labels. Bottled teas and tea blends may contain added sugar, flavorings, or other ingredients.
• Treat herbal teas as herbs. If you take medication or have a health condition, check for interactions.
• Grow slowly and observe. Test the soil before feeding your tea shrub, and harvest lightly until it is established.
• Keep the evidence in perspective. Tea can be enjoyable and fit a healthy pattern, but it does not replace medical care.
