Best Tea for Psoriasis: 3 Options and Their Evidence

Green tea, black tea and white tea are three reasonable teas to drink if you have psoriasis, but none is proven to improve it. The ai symptom analyzer can help you organize symptoms to discuss with a clinician; it cannot diagnose psoriasis or determine whether tea will help.

These are practical drink choices, not ranked treatments. For a broader look at hydration and other choices, see the best drinks for psoriasis.

3 teas to consider for psoriasis

All three teas come from the Camellia sinensis plant. They contain plant compounds called polyphenols, including catechins, which are studied for their antioxidant and inflammatory effects. Psoriasis is an immune-mediated condition, but finding a possible effect on inflammation does not establish that drinking a tea improves psoriasis.

There is no established therapeutic amount of any of these teas for psoriasis, and the available evidence does not show that one is better than another for controlling symptoms. Choose primarily by taste, caffeine tolerance and whether the drink fits your routine—not by an expectation that it will clear plaques.

Green tea

Possible mechanism: Green tea contains catechins, plant compounds of interest in skin research. Researchers have explored whether delivering these compounds to the skin could affect processes involved in skin disorders, including psoriasis. That is a research question, not proof that a cup of green tea has the same effect.

Evidence: A 2022 review of tea catechins and skin delivery discusses ways to improve the delivery of catechins in topical formulations. It does not establish that drinking brewed green tea improves psoriasis. The review concerns the compounds and their delivery, rather than a demonstrated benefit from the drink.

How to brew: Place a green tea bag or loose green tea in a cup, add hot water and follow the package directions for the water temperature and steeping time. Remove the bag or strain the leaves. Drink it plain if you enjoy the taste; there is no evidence-based brewing method or dose for psoriasis.

Cautions: Green tea usually contains caffeine, although the amount varies by product and preparation. If caffeine makes you anxious, disrupts your sleep or causes a racing heartbeat, choose a decaffeinated version or another suitable drink. Avoid treating concentrated green tea extract as equivalent to brewed tea: supplements containing the extract have been linked to rare liver injury.

Do not assume that applying brewed green tea to a patch will reproduce the topical formulations discussed in research. Ask your clinician before putting a new product on irritated or broken skin.

Black tea

Possible mechanism: Black tea also contains tea polyphenols, but its leaves are processed differently from green tea leaves. Those compounds are a reason black tea is discussed in general research on tea, not evidence that it changes the immune activity responsible for psoriasis.

Evidence: The available evidence does not establish that drinking black tea reduces psoriasis plaques, itching or flares. There is also no sound basis from the evidence listed here to say it works better or worse for psoriasis than green tea. Consider it a beverage choice rather than a treatment choice.

How to brew: Put a black tea bag or loose black tea in a cup, add hot water and steep according to the package directions. Remove the bag or strain the leaves before drinking. Adjust the strength for taste rather than trying to reach an unproven therapeutic strength.

Cautions: Black tea contains caffeine, and the amount varies with the product and brewing method. If it affects your sleep or makes you feel jittery, try a decaffeinated version or have it earlier in the day. Poor sleep can make living with symptoms harder, so a tea you tolerate comfortably may be more useful to your routine than one you dislike.

Adding sugar, milk or another flavoring is a matter of preference; none has been shown here to turn black tea into a psoriasis treatment. Be cautious of blends that combine black tea with concentrated herbal ingredients, because their risks may differ from those of plain brewed tea.

White tea

Possible mechanism: White tea comes from the same plant as green and black tea and also contains polyphenols. Its composition depends on the product and preparation. The presence of these compounds does not show that the drink reaches affected skin in an amount that changes psoriasis.

Evidence: White tea has not been established as a psoriasis treatment in the evidence listed here. The review of catechins and topical delivery should not be read as a clinical trial of drinking white tea. It also does not establish a useful amount, brewing time or schedule for psoriasis.

How to brew: Place a white tea bag or loose white tea in a cup, add hot water and follow the package directions for water temperature and steeping time. Remove the bag or strain the leaves. Choose it if you prefer its flavor, not because it is marketed as a gentler or more potent skin remedy.

Cautions: White tea can contain caffeine; do not assume it is caffeine-free or always lower in caffeine than another tea. Check the product label if caffeine matters to you, and choose a decaffeinated product when appropriate. As with the other teas, a concentrated extract or multi-ingredient supplement is not the same as a cup of brewed tea.

If you notice that a particular drink seems to coincide with discomfort, record what you drank and what happened, then discuss the pattern with a clinician. A flare after a cup of tea does not by itself prove the tea caused it, and there is no need to restrict all tea on that basis.

Which teas should you avoid with psoriasis?

Avoid teas marketed as psoriasis cures, detoxes or cleanses. No tea has been established as a psoriasis cure, and these products may contain several herbs, laxatives or concentrated extracts. The liver and kidneys do most of the body’s detoxification; drinking a special tea does not flush toxins out of psoriasis patches.

Be particularly cautious with licorice-root tea, especially if you have high blood pressure, heart disease or kidney disease. Licorice can raise blood pressure and lower potassium, particularly with repeated or high intake. Ask a healthcare professional before using it rather than assuming that a herbal label means it is safe.

Avoid St. John’s wort tea unless your healthcare professional has checked it against your medicines. It can interact with many prescriptions, including some immunosuppressants and contraceptives. Multi-ingredient herbal teas deserve the same check because the front of a package may not make every ingredient obvious.

A plain tea does not need to be avoided solely because you have psoriasis. Read labels carefully, though, and skip a product that has caused a reaction for you. If you are considering an unfamiliar herbal blend, take the ingredient list to your pharmacist or clinician for review.

Who should be careful, and when should you see a doctor?

If you are pregnant or breastfeeding, ask your healthcare professional about caffeine and herbal ingredients before making a tea a regular habit. The same caution applies to children: check with a pediatric clinician before giving a child caffeinated or medicinal herbal teas. Decaffeinated tea can still contain ingredients other than tea leaves, so read the label.

If you have heart disease, high blood pressure, kidney disease, liver disease or an anxiety condition, ask whether caffeine or a particular herbal ingredient is suitable for you. If you take medicines—including psoriasis medicines, blood thinners or other prescriptions—check unfamiliar herbal products and extracts with your pharmacist or clinician. Continue prescribed treatment as directed; do not replace it with tea or stop it without medical advice.

Arrange a medical appointment if you have a new rash, worsening or extensive patches, significant itching, or symptoms that disrupt sleep or daily life. A clinician can assess whether psoriasis or another condition is responsible and discuss appropriate care. Report new joint pain, stiffness or swelling as well, because these symptoms need assessment in someone with psoriasis.

Seek urgent medical care for widespread redness and peeling, especially if you feel unwell, or for a rapidly worsening rash with fever, chills or pustules. These symptoms can signal a serious problem and should not be managed with tea at home.
