Health Benefits of Wild Strawberry Leaf Tea

Herbal tea made by infusing strawberry leaves – especially wild strawberry leaves – in hot water has a long history both as a culinary treat and as a herbal remedy. In folk medicine, this caffeine-free alternative to black tea has been used to treat everything from gastrointestinal problems and rheumatoid arthritis to excessive menstrual bleeding and water retention. Scientific research on the health benefits of wild strawberry leaf tea, however, is somewhat limited. What we do know is that wild strawberry leaf extract has extremely strong antioxidant properties in vitro and that is has vasodilatory effects, similar to those of hawthorn leaf extract. Scientific studies have also proven that wild strawberry leaves are a good source of ellagic acid (compound with anti-cancer potential) and tannins (polyphenols that have been used to treat diarrhea). To get the full lowdown on the potential health benefits of wild strawberry leaf tea, keep reading.

Wild Strawberry Leaf Extract Ranks on Top in Terms of Antioxidant Activity

Wild strawberry leaf tea may be a great option for those who want to keep their antioxidant levels topped up and are looking for a caffeine-free alternative to green tea or black tea. A study published in the Czech Journal of Food Sciences found that a water extract of wild strawberry leaves had the strongest antioxidant activity among the tested herb and berry extracts, as measured by DPPH free radical scavenging ability. This study assessed the antioxidant activity of water extracts of 17 medicinal herbs and berries, including oregano tops, blackberry leaves, raspberry leaves, rosehips, thyme tops, nettle flowers, mint, elderflowers, linden flowers, chamomile flowers, blueberries, rowan berries and sea-buckthorn berries.

Vasodilatory Effects

While it is too early to state that wild strawberry leaf tea is good for people with high blood pressure, the results of early research carried out in animals have been promising. A Croatian study published in the journal Phytomedicine in 2009 found that an aqueous extract of wild strawberry leaves had marked vasodilatory activity in isolated guinea pig hearts and rat aortic rings. In terms of potency, the vasodilatory effects of the wild strawberry leaf extract were similar to those of hawthorn extracts. The vasodilatory effects of hawthorn leaf extracts have been well documented, which is why the researchers chose hawthorn (Crataegus oxycantha, L) as the reference plant for this study.

As you may know, vasodilators are substances that dilate blood vessels. They work by relaxing the muscles in the walls of your arteries, allowing the blood flow more easily. As a result, your heart doesn't have to pump as hard and your blood pressure is reduced.

Wild Strawberry Leaves Contain Ellagic Acid

You may have already heard of ellagic acid, a compound that has been shown to neutralize cancer-causing substances, boost the immune system, and induce apoptosis (self-destruction) of cancerous cells. Wild strawberries, raspberries, blackberries, pomegranates, and cranberries are perhaps the most famous food sources of ellagic acid, but also some edible leaves – including wild strawberry leaves and blackberry leaves – have been shown to contain this powerful anti-cancer compound. Whether drinking strawberry leaf tea can actually have any significant anti-cancer effects in humans, however, has not been evaluated in clinical trials (as of the writing of this article).

Tannins in Wild Strawberry Leaf Tea May Provide Benefits for the Gastrointestinal Tract

Infusion made from wild strawberry leaves has been traditionally used to treat diarrhea, indigestion, and dysentery, and now there's at least some evidence to support this use. A study published in Gene, Genome and Genomics in 2011 analyzed the phytochemical composition of wild strawberries native to Chile and found that them to be a rich source of tannins. Also the leaves of cultivated strawberries have been shown to contain significant amount of tannins. Tannin-rich plant extracts have been widely studied, particularly in relation to their anti-diarrhea activity.

Uses in Folk Medicine

Folk healers and practitioners of herbal medicine have also used wild strawberry leaf tea to treat conditions like rheumatoid arthritis, skin rashes, respiratory complaints, leucorrhoea, catarrh, nervousness, excessive menstrual bleeding, and water retention. However, no or limited research is available to support these uses.
