The latest scientific research has established that Fennel Tea benefits can offer as much potential as the likes of Camomile, Peppermint and Hibiscus Tea. While perhaps not as well known as its counterparts, it is an infusion worthy of including in your daily routine. The following article will be making a case for just that. Please keep reading to find out more information - supported by evidence. 

Once you’ve discovered the facts and figures, you’ll undoubtedly want to try a cup of delicious, wholesome and increasingly popular Fennel Tea for yourself. Look no further than The Kent and Sussex Tea and Coffee Company, where everything is packed fresh to order to ensure its quality and consistency. But let’s not get ahead of ourselves. Now is the time to uncover how it helps your health.

Fennel Tea Properties

Fennel Tea Properties and Nutrition Facts

Fennel Tea’s nutritional value is the primary reason why it is so sought after. It contains a wealth of vitamins, minerals and other antioxidants that, with frequent consumption, combat free radicals in the body. Free radicals, in turn, are unpaired - and unsafe! - electrons that wreak havoc on your system when left unchecked. Fennel Tea benefits serve as a line of defence through the following constituents:

Fennel Tea Benefits

The age-old history of Fennel Tea’s health benefits is a fascinating story. During the Olympics in ancient Greek times, athletes ate Fennel Seed Tea to boost stamina before a race. Doctors of the period then prescribed the leaves to nursing mothers to increase breast milk (more on that below). Centuries later, the renowned Roman physician Pliny the Elder (23-79 CE) recommended them for twenty-two ailments. 

The difference today is that we have the research to support such claims, which is what we’ll be exploring in the rest of our article. You’ll learn about its ability to ease insomnia, aid digestion, boost immunity, promote weight loss, relieve menstrual cramps and much more. Though there are side effects to recognise (something we’ll do in due course), it is, for the most, good news going forward.

Fennel Tea Help You Sleep

1. Does Fennel Tea Help You Sleep?

Insomnia is a common sleeping disorder mostly found in adults. According to statistics from the National Institutes of Health, approximately 30% of the general population struggles with it. The most famous Herbal Tea associated with a restful night is, of course, Camomile Tea. But utilising Fennel Tea benefits for sleeping issues could also lend a helping hand - albeit in somewhat different ways.

One such way is that its calmative properties serve as muscle relaxants, which then ease muscle tensions in the digestive system that might be more active before bedtime. Another way is the fact that it is an appetite suppressant, thereby helping you avoid late-night snacking when you should be asleep! Additionally, its absence of caffeine makes it an excellent alternative to the likes of Black and Green Tea.

Increase Oestrogen

2. Does Fennel Tea Increase Oestrogen?

Evidence has found that Fennel Tea increases oestrogen and, therefore, acts as a hormone balancer. This can promote your health and wellbeing via several processes. There are suggestions, for example, that it prevents female hirsutism. One study discovered that topical use (i.e. applying it to the skin) reduced male pattern body hair on women, which, understandably so, boosted participants’ confidence. 

Furthermore, scientists have theorised that the benefits of Fennel Tea for menopause work by reducing hormonal imbalance after drinking it. Anecdotal reports have even noted the possibility that it promotes breast enlargement, although it is far from proven. However, it is vital to note that those with cancers that are sensitive to oestrogen should avoid the Herbal Tea under any and all circumstances. 

Fennel Tea and Bloating

3. Fennel Tea and Bloating?

Bloating is an all too common and most irksome digestive issue that takes place in the abdomen (stomach), often through the gastrointestinal tract filling with air or gas. When people experience bloating, it tends to feel like they’ve eaten a big meal and there’s no room for more food. The abdomen feels full and tight, causing much discomfort and, on occasions, varying measures of pain. 

Is Fennel Tea good for bloating? You can count on it. First is its diuretic activity (more on that later). Second is its capacity to act as a mild laxative and, as a result, has a stimulating effect on the bowel. Third, which we’ve already mentioned, is its calmative properties. Other options worth considering include Dandelion Tea, Peppermint Tea and Green Tea Benefits to alleviate bloating.

Fennel Tea for Digestion

4. Fennel Tea for Digestion?

Is Fennel Tea good for digestion as a whole? Absolutely. For starters, its chemical compounds have anti-inflammatory, antispasmodic and muscle-relaxant properties. A 2012 review published by the International Journal of Food Sciences and Nutrition showcased promising findings. It discovered that the herb increased spontaneous gastric motility and gastric acid secretions in animal models.

Meanwhile, according to a 2016 study, a combination of Fennel Tea and curcumin found in Turmeric Tea helped those living with Irritable Bowel Syndrome (IBS). After thirty days of consumption, volunteers involved in the project experienced symptom relief and less abdominal pain. Another trial blending Fennel, Caraway Seeds, Wormwood and Peppermint Tea established similar findings.

Fennel Tea for Heartburn

5. Fennel Tea for Heartburn

Acid reflux (known widely as “heartburn”) is a condition easily recognised by a burning pain in the lower chest area. It occurs when acid in the stomach flows back up into the food pipe (oesophagus). Should it happen more than twice a week, it might be a sign of Gastroesophageal Reflux Disease (GERD). Is Fennel Tea good for acid reflux and GERD? It turns out to be a little complicated. 

You may have noticed while reading about Fennel Tea for digestion that it increases gastric acid. This makes it somewhat of a mixed bag for supporting those with acid reflux. On the other hand, certain experts have noted that it is low in acid despite it promoting acid secretion. The bottom line is that until we know more, The Kent and Sussex Tea and Coffee Company does not endorse it for such a purpose.

Coughs and Colds

6. Fennel Tea for Coughs and Colds

Your immune system is an expansive network of cells, organs, proteins and tissues working together to protect against pathogens. The body would be open to attack from viruses, parasites and harmful bacteria without it. But even then, there is still the chance that some nasty attackers will slip through the net and cause colds, flu (influenza) and other illnesses that make you feel “under the weather”. 

The abundance of Vitamin C in your cuppa ensures that it boosts the immune system to stop coughs and colds from manifesting in the first place. Drinking Fennel Tea for sore throats is likewise a worthwhile endeavour when you’re already sick. The evidence comes from a study conducted by Italian researchers, which found that it loosened mucus in the lungs and so relieved symptoms.

Fennel Tea Good for Weight Loss

7. Fennel Tea Good for Weight Loss

We’ve already established that Fennel Tea is an appetite suppressant. It stands to reason, then, that it helps you steer clear of snacks in between meals. Are you worried that it might be as bad for you as those naughty nibbles you’re avoiding? Take comfort in knowing that there are no four calories per serving, making it a suitable alternative to sugary and fatty soft drinks. It tastes better, too, in our opinion. 

And that’s not the end of it. Preliminary (emphasis on “preliminary”) research points to the possibility that it boosts the metabolism of fat cells. Doing so enables the body to burn fat quicker and more efficiently, leading to periods of exercising producing better and more noticeable results. Just don’t expect it to do all of the hard work for you. Keep eating well and frequently exercising to see dramatic changes.

Fennel for Menstrual Cramps

8. Fennel Tea for Menstrual Cramps

Experiencing moderate cramping during menstrual periods is a normal part of the cycle. However, it doesn’t make it any less uncomfortable or painful, nor prevent your period from interfering with your daily life. There are no fix-all solutions that will work for everyone. What there are instead are over-the-counter medications and, for some women, Fennel Tea for menstrual cramps. 

The proof comes from an Iranian study that involved a combination of Fennel extract and Vitamin E. It demonstrated a remarkable reduction in cramping pain from menstruation following the consumption of the mixture. Participants later concluded that it was more effective than medicinal pain relievers. The main reason is the Tea’s antispasmodic properties that relax the muscles in the uterus.

Benefits Skin Health

9. Fennel Tea Benefits Skin Health

Topical application of Fennel Tea for acne could combat blemishes and restore your skin to its former glory. The condition, as those who live with it will know, occurs when hair follicles become clogged with oil and dead skin cells. It typically leads to a breakout in blackheads, whiteheads or pimples on the face, forehead, chest, upper back and shoulders. Enter the Tea’s anti-inflammatory response. 

Its antioxidants also play a role on a molecular level. Kaempferol and quercetin, in particular, fight several skin disorders, including acne. And there’s more. Fennel Tea benefits likewise act as a toner, while its anti-ageing properties reduce the presence of wrinkles and improve the skin’s texture. Think twice, in other words, about that £90 tub of skincare cream when there is a natural remedy available.

Fennel Tea Side Effects

Fennel Tea Side Effects

Is it safe to drink Fennel Tea every day? It depends on the person as there is a risk of side effects. Despite listing it as a benefit, we must stress that its oestrogenic properties might hinder rather than help menopausal symptoms in some instances. Equally, there is a chance of it decreasing milk supply rather than increasing it. Such complications likely stem from its influence on hormones. 

Additionally, it would make sense to once more highlight that anyone living with cancer that is sensitive to oestrogen should avoid it. Can Fennel Tea cause diarrhoea as well? Technically, yes, as it does have laxative properties with excessive consumption. Should you have any other concerns or suffer from other issues, we’d recommend that you speak with a doctor, nurse or another health professional.

Is Fennel Tea a Diuretic

Is Fennel Tea a Diuretic?

A quick recap: Fennel Tea benefits extend to digestion on multiple fronts, as well as sleep, hormone balancing, minor illnesses, weight loss, menstrual cramps and skin health. We now return to a question that countless people have wondered: Is Fennel Tea a diuretic? This term refers to promoting urine function, assisting those with high blood pressure, heart failure, swollen tissues and kidney disease.

We can once again offer good news: Fennel Tea appears to have a mild diuretic response. But it still might not be the best choice compared to the likes of Dandelion Root Tea and Milk Thistle Tea, both of which boast a considerable amount of supportive evidence. Other types of Diuretic Tea worth brewing include, but are not limited to, Black, Peppermint, Nettle, Ginger and Rooibos Tea. 

Fennel Tea Pregnancy and Breastfeeding

Fennel Tea Pregnancy and Breastfeeding

Ancient Greek doctors who once prescribed Fennel Tea to boost breast milk supply seem to have been right to do so. This is due to it being a galactagogue, which is something that increases breast milk through phytoestrogens, similar to the oestrogen hormone in the body. Two studies have established a rise in parameters such as milk volume, fat content and infant weight gain after having Fennel Tea. 

What about before you’ve given birth? After all, it is usually advisable to err on the side of caution when drinking Herbal Tea while pregnant. One study observed its influence on a pregnant woman’s body, concluding that it disturbed foetal growth and development. It also recognised that because of its oestrogenic properties, high doses might have toxic effects on foetal cells.

Fennel Tea for Babies

Between 20-25% of babies experience colic, a condition where an infant engages in lengthy episodes of crying for more than three hours a day for no immediately discernible reason. It could be happening because of restlessness, sleeplessness or, in severe cases, gastrointestinal issues. Is Fennel Tea good for babies? It’s a topic of much debate as Fennel Tea for colic and baby gas has a controversial history. 

According to research from the University of Maryland Medical Center, USA, its consumption “helps relax the gastrointestinal tract and gets rid of gas”. According to a 2003 study published in the Journal of Alternative Therapies, 65% of infant participants had no colic symptoms after having Fennel Tea. We nevertheless recommend medical consultation before trying it with your children.


There you have it: Fennel Tea benefits and side effects examined in-depth. We stock two types here at The Kent and Sussex Tea and Coffee Company. The first is Loose Leaf Fennel Tea, which we’ve explored here. The second is Fennel Seed Tea, which has its own unique potential.
