Strawberries are a quintessential part of the British summer. We slice them onto scones, blend them into smoothies, and pile them high with cream during Wimbledon. However, while most of us are familiar with the sweet, red fruit, fewer people realise that the leaves of the strawberry plant hold significant potential as a therapeutic herbal remedy.
Strawberry leaf tea has been used for centuries in traditional medicine to treat various ailments, ranging from digestive issues to joint pain. Today, modern science is beginning to catch up with this ancient wisdom, investigating the compounds found within the greenery of the Fragaria genus.
If you are looking to diversify your herbal tea rotation or are seeking a caffeine-free alternative to black tea, strawberry leaf tea might be the perfect addition to your cupboard. It offers a mild, fruity flavour profile and a host of bioactive compounds that may support your overall wellbeing.
In this article, we explore the potential health benefits, nutritional profile, and safety considerations of drinking strawberry leaf tea.
What Is Strawberry Leaf Tea?
Strawberry leaf tea is an herbal infusion made from the fresh or dried leaves of the strawberry plant. While the leaves of the common garden strawberry (Fragaria x ananassa) can be used, herbalists often prefer the leaves of the wild strawberry (Fragaria vesca).
Wild strawberry leaves are generally considered to have a higher concentration of beneficial compounds compared to their cultivated counterparts. These leaves are typically harvested in the spring or early summer before the fruit fully ripens, as this is when their phytonutrient content is thought to be at its peak.
Unlike traditional teas derived from the Camellia sinensis plant (such as green or black tea), strawberry leaf tea is naturally caffeine-free. This makes it an excellent option for those looking to reduce their stimulant intake or for an evening beverage that won’t disrupt sleep patterns.
The tea itself usually brews into a light golden colour with a subtle, pleasant taste that is slightly sweet and earthy, lacking the bitterness often associated with tannic herbal teas.
Historical and Traditional Use
Historically, the tea was not just a pleasant beverage but a functional medicine. In traditional European herbalism, it was frequently utilised as a diuretic and an astringent. It was often prescribed to treat diarrhoea, dysentery, and even to soothe sore throats when used as a gargle.
It is important to note that while traditional use provides a fascinating backdrop, we must look to modern evidence to confirm these benefits.
Potential Health Benefits of Strawberry Leaf Tea
Research into the specific health effects of strawberry leaves is ongoing, but initial studies and chemical analyses have identified several key mechanisms through which this tea may support health.
1. Rich in Antioxidants
One of the most compelling reasons to consume strawberry leaf tea is its impressive antioxidant profile. Antioxidants are molecules that fight free radicals in your body. Free radicals are compounds that can cause harm if their levels become too high, leading to oxidative stress.
Strawberry leaves contain significant amounts of ellagic acid, a polyphenol found in many red fruits and berries. According to Healthline, maintaining a diet high in antioxidants is crucial for reducing the risk of chronic diseases, including heart disease and certain cancers.
In addition to ellagic acid, these leaves are a good source of Vitamin C, which further supports immune function and skin health. Regular consumption may help bolster your body’s natural defences against environmental stressors.
2. May Support Digestive Health
For centuries, the primary use of strawberry leaf tea was to settle an upset stomach. This effect is largely attributed to the presence of tannins. Tannins are naturally occurring compounds that have astringent properties.
This means they can bind to proteins and other organic compounds, effectively helping to reduce inflammation in the digestive tract. This binding action is why the tea has traditionally been used to treat mild diarrhoea.
Furthermore, by reducing inflammation in the gut lining, the tea may provide relief from cramping and bloating. Organisations like Guts UK highlight the importance of managing gut inflammation for overall health, and gentle herbal remedies can sometimes play a supportive role alongside medical treatment.
3. Potential Blood Sugar Regulation
Emerging research suggests that the bioactive compounds in strawberry leaves may help regulate blood sugar levels. This is particularly relevant given the rising prevalence of type 2 diabetes in the UK.
Some studies indicate that ellagic acid and other flavonoids found in the leaves may inhibit enzymes involved in breaking down starches into glucose. This inhibition can lead to a slower release of sugar into the bloodstream following a meal, preventing sharp spikes in blood glucose.
While this should not replace prescribed medication, incorporating the tea into a balanced diet could be a helpful lifestyle modification. For comprehensive advice on managing glucose levels, resources from Diabetes UK offer vital guidance on diet and monitoring.
4. Cardiovascular Health
Heart health is a major concern globally. The flavonoids found in strawberry leaves, including quercetin and kaempferol, are associated with cardiovascular protection.
Some research published in the National Library of Medicine suggests that these compounds may help improve blood flow by promoting vasodilation (the widening of blood vessels). This can potentially assist in lowering high blood pressure, a significant risk factor for heart attacks and strokes.
Additionally, the antioxidant activity prevents the oxidation of LDL (bad) cholesterol, a critical step in the formation of arterial plaque. The British Heart Foundation emphasises that dietary choices play a massive role in maintaining healthy blood pressure levels.
5. Diuretic Properties
Strawberry leaf tea acts as a mild diuretic. Diuretics help the body eliminate excess fluid and salt through urine. This can be beneficial for individuals suffering from mild water retention or bloating.
By promoting the removal of excess fluids, the tea may support kidney function and help clear out toxins from the urinary tract. However, because it increases fluid loss, it is vital to drink plenty of plain water to stay hydrated. Refer to NHS Inform for guidelines on maintaining proper hydration and mineral balance.

Side Effects and Precautions
While strawberry leaf tea is generally considered safe for most people, there are specific precautions to consider before adding it to your daily routine.
1. Allergic Reactions
Strawberries belong to the Rosaceae family. If you have an allergy to strawberries, you may also react to the leaves. Symptoms of a mild allergic reaction can include itching in the mouth, hives, or a skin rash.
In rare cases, severe reactions can occur. If you experience difficulty breathing or swelling of the throat, seek immediate medical attention. The NHS provides detailed information on recognising and managing food allergies.
2. Pregnancy and Breastfeeding
Although raspberry leaf tea is famous for its use during pregnancy, strawberry leaf tea has not been studied as extensively. Some herbalists advise caution due to the tannin content and the potential for uterine stimulation, although this effect is generally considered mild.
If you are pregnant or breastfeeding, it is always best to consult with your GP or midwife before consuming herbal products. The Royal College of Obstetricians and Gynaecologists often provides guidance on safe dietary practices during pregnancy.
3. Interference with Iron Absorption
The tannins that make this tea excellent for diarrhoea can also inhibit the absorption of non-heme iron (plant-based iron). If you suffer from iron-deficiency anaemia, you should avoid drinking this tea immediately before or after meals.
To maximise iron uptake, drink the tea between meals rather than with them. For more on how diet affects nutrient absorption, you can consult resources from GOV.UK regarding iron and health.
Frequently Asked Questions
Does strawberry leaf tea taste like strawberries?
Not exactly. While it has a subtle fruity note, the flavour is more herbal and earthy, similar to a mild green tea but without the bitterness. It is pleasant and light.
Can I make tea from the strawberry leaves in my garden?
Yes, provided they have not been sprayed with pesticides. Garden strawberry leaves (Fragaria x ananassa) are edible, though wild strawberry leaves (Fragaria vesca) are preferred for their potency. The Royal Horticultural Society offers excellent guides on identifying and growing these varieties safely.
How do I prepare the tea?
Use approximately one teaspoon of dried leaves (or two teaspoons of fresh leaves) per cup of boiling water. Let it steep for 5 to 10 minutes. You can add a slice of lemon or a drop of honey to enhance the flavour.
Is it safe to drink every day?
For most healthy adults, drinking 1 to 3 cups daily is considered safe. However, due to the diuretic effects and tannins, excessive consumption may lead to constipation or dehydration. Moderation is key.
The Bottom Line
Strawberry leaf tea is an overlooked gem in the world of herbal infusions. It offers a caffeine-free alternative to traditional tea, packed with antioxidants like ellagic acid and Vitamin C.
