What is Fennel Tea

What is Fennel Tea?

Fennel (Foeniculum vulgare) is a hardy, aromatic, perennial plant belonging to the Carrot (Apiaceae) family.

It grows yellow flowers and feathery leaves, which, although native to the Mediterranean, have since spread across the world. When brewed, most recognise it for its distinct aromatic character, bold anise notes and herbaceous undertones. 

No leaves from the Camellia sinensis (Tea) plant find themselves in this infusion. This means that, technically speaking, Fennel Tea isn’t a “Tea” at all. What it is, then, is a Herbal Tea or “Herbal Tisane” - although the latter term is rarely used.

Nevertheless, the industry has long adopted it as an “honorary” Tea, one that comes with Fennel Tea benefits.

History of this Herbal Tea

History of Fennel Tea

Fennel Tea shares close ties with the history of humankind. The plant itself grew on the site of the infamous Battle of Marathon in 490 BCE.

Such was its abundance there, in fact, that the decisive Greek victory over the invading Persian army took its name from this herb. The word “Marathon” (μαραθώνας), translated from Greek, means “a place of Fennel.” 

Famously, a young soldier called Pheidippides ran forty-two kilometres from Marathon to Athens to announce the outcome of the battle. He tragically collapsed and died after telling the good news, but his endeavours inspired the marathon sporting event closely associated with the Olympics.

It was during this period that athletes began to eat the Fennel seeds to boost their stamina before a race. 

Ancient Greek doctors eventually prescribed Fennel Tea to nursing mothers to increase breast milk. This is still the case today, and is but one example of Fennel Tea benefits.

Centuries later, Pliny the Elder (23-79 CE), the renowned Roman physician, recorded that serpents rubbed against it to improve their eyesight. He would go on to note twenty-two of its uses for humans, too. 

In Anglo-Saxon culture, Fennel became one of the “Nine Holy Herbs” alongside others such as Camomile and Nettle Tea. Hundreds of years after, during the 12th century, King Edward I would recommend it for warding off witches and evil spirits.

It then appeared in “The Book of Physicians of Myddfai,” its text reading: “He who sees Fennel and gathers it not, is not a man but a devil.”

Fennel Tea Properties

Fennel Tea Properties

It’s time now to start examining the science behind Fennel Tea benefits, beginning with its Fennel Tea properties.

These chemical compounds, when combined, can combat free radicals in the body, the product of natural, though often harmful, human oxidation.

This, in turn, reduces the risks of developing numerous chronic conditions - among other abilities.

Why Fennel Tea is Good for You

Alpha-Pinene Beta-Myrcene Bitter-Fenchone
Camphene Estragole (Methyl-Chavicol) Fenchone
Limonene P-Cymen Safrole
Beta-Carotene Vitamin C Calcium
Magnesium Iron Manganese
Potassium Sodium Zinc

It’s important to note, however, that some of the above constituents only exist in trace amounts in Fennel Tea. That means, in other words, that at least some Fennel Tea properties lack the potential of others.

Their strength, then, comes about from working together. If you’re interested in how they can improve your life in small yet significant ways, please keep reading.

Fennel Tea Benefits

Fennel Tea Benefits

Is Fennel Tea good for you? Absolutely. And in many, many ways. According to the latest scientific research, it promotes weight loss, helps breastfeeding mothers, aids digestion, combats heartburn, relieves menstrual cramps and even prevents colic.

Most remarkable of all, perhaps, is that this is to name but a few Fennel Tea health benefits. There are many more waiting to be discovered.

We must stress, though, that the following research is still in its early stages. Although it appears promising, it remains paramount that you seek medical consultation should you experience any of the ailments mentioned above.

First and foremost, The Kent and Sussex Tea and Coffee Company cares about the welfare of its customers. We are here to show, not endorse, the following evidence.

Fennel Tea for Babies

Fennel Tea for Babies

Is Fennel Tea good for babies? Yes, according to research from the University of Maryland Medical Center, USA, which recommends this herbal infusion for colic in babies.

It first noted that one of the leading causes of colic is gastrointestinal discomfort. As a result, they write, Loose Fennel Tea “helps relax the gastrointestinal tract and gets rid of gas.”

Other studies recognise its antispasmodic properties as the reason why it works. A 2003 project conducted by Alternative Therapies, in particular, found that 65% of infant participants had no symptoms of colic after consuming this herb.

This was significantly high to the second group of children who received a placebo. However, it’s essential to talk to a doctor before trying Fennel Tea for babies.

Fennel Tea Breastfeeding

Fennel Tea Breastfeeding

Is Fennel Tea good for breastfeeding, too? Greek doctors, thousands of years ago, seemed to think so. Now, though, it has the backing of modern science.

The belief is that it is a galactagogue, which is something that increases a mother’s breast milk supply.

This is because it has phytoestrogens, considered similar to the oestrogen hormone found naturally in the body.

Two small studies offer proof. They discovered a significant rise in important parameters such as milk volume, fat content and infant weight gain following Fennel Tea galactagogue therapy.

However, please be aware that this beverage should NEVER replace evaluation and counselling when it comes to breast milk production.

Consult with medical professionals before trying Fennel Tea to increase milk supply.

Does Fennel Tea Help you Sleep

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, roughly 30% of the general population struggles with this condition.

The most famous infusion for having a restful night is, of course, Camomile Tea. However, Loose Leaf Fennel Tea benefits sleep, too - albeit in slightly different ways.

Research indicates that it is a muscle relaxant, primarily muscles in the digestive system (we’ll talk about this more later), which can have a calming effect.

Additionally, it acts as an appetite suppressant, thus helping you to avoid late-night snacking. Other Herbal Tea types worth considering include Lavender Tea, Rose Petal Tea and Lemon Balm Tea. Nevertheless, Fennel Tea for sleep is a great choice.

Does Fennel Tea Increase Estrogen

Fennel Tea Increase Estrogen?

Evidence of Fennel Tea having estrogen properties indeed exists. This can enable it to act as a hormone balancer, thus promoting your health and wellbeing in several ways.

There are suggestions, for example, that it prevents female hirsutism. One study found that topical use of Fennel Tea reduced male pattern body hair on women, which, understandably so, boosted participants’ confidence.

Furthermore, some scientists have recognised a reduction in hormonal imbalance caused by menopause after drinking this beverage. There is even the possibility, although not yet proven, that Fennel Tea for breast enlargement is a worthwhile decision.

So, if you’re wondering “does Fennel Tea make your breasts grow?,” the answer is “maybe.” Please note, however, that side effects can arise from too much estrogen.

Fennel Tea and Bloating

Fennel Tea and Bloating

Many consider Fennel Tea one of the Best Teas for Bloating. This quite common digestive issue takes place in the abdomen (stomach).

It is usually the product of gastrointestinal tract filling with air or gas. When you’re bloated, it often feels like you’ve eaten a big meal and there’s no room for more food. The abdomen feels full and tight, which can be very uncomfortable or even painful.

Fennel Tea for bloating helps in two ways. First, it has some diuretic activity (read more in our blog, “Is Tea a Diuretic?”), meaning it enables someone to excrete excess water.

It can also act as a mild laxative and, as a result, has a stimulating effect on the bowel. Alternatively, you can try Green Tea Benefits, Dandelion Tea or Peppermint Tea to alleviate bloating.

Fennel Tea for Digestion

Fennel Tea for Digestion

Traditional Chinese Medicine (TCM) has long recognised Fennel Tea benefits as excellent for aiding digestion. More recent scientific research, too, supports this claim.

We will be examining a couple of specific areas in which this infusion can help your digestive system in a moment. Right now, however, let’s look into it from a somewhat broader perspective.

Many of the vitamins, minerals and antioxidants found in it offer anti-inflammatory, antispasmodic and muscle-relaxant properties.

Additionally, a 2012 review published by the International Journal of Food Sciences and Nutrition showed promising findings.

It discovered that the herb increased spontaneous gastric motility and gastric acid secretions in animal models.

Is Fennel Tea Good for Acid Reflux

Is Fennel Tea Good for Acid Reflux?

Acid reflux is a condition easily recognised by a burning pain, known as heartburn, in the lower chest area. It occurs when acid in the stomach flows back up into the food pipe (oesophagus).

If this happens to an individual more than twice a week, it might be Gastroesophageal reflux disease (GERD). You may have noticed from the above benefit, however, that this beverage increases gastric acid.

So, is Fennel Tea good for acid reflux or not? In other words, is Fennel Tea for heartburn a blessing or a curse? It appears to depend on the person.

Many describe it as low in acid despite it promoting acid secretion in the body, thus making it somewhat of a mixed bag. For this reason, we do not at this stage recommend Fennel Tea for acid reflux. Instead, we support ongoing research.

Fennel Tea for IBS

Fennel Tea for IBS

Irritable Bowel Syndrome (IBS) is a common problem that affects the gastrointestinal system in many ways. It can lead to symptoms such as stomach cramps, bloating, diarrhoea and constipation, among others.

Most sufferers find it to be a lifelong problem, with it currently affecting between 10% and 20% of the general population. Fennel Tea for IBS, meanwhile, seems to have great potential.

A blend of Fennel and Curcumin (found in Turmeric Tea), according to a 2016 study, yielded positive results.

Participants, after 30 days of consumption, experienced symptom relief and had less abdominal pain. Another research project combining Fennel, Caraway Seeds, Wormwood and Peppermint Tea showed similar findings. Whether this Tea works by itself, though, remains to be seen.

Fennel Tea for Coughs and Colds

Fennel Tea for Coughs and Colds

Fennel Tea benefits here have been proven to work well against coughs brought on by minor illnesses. This is partly because it contains an abundance of antioxidants and, most importantly, Vitamin C.

The latter chemical compound, in particular, famously boosts the immune system. In doing so, it supports your body in its vital work fighting viruses, parasites and harmful bacteria.

This helps very little, though, when you’re already feeling unwell. However, according to Italian researchers, drinking Fennel Tea can also loosen mucus in your lungs and relieve your cough or sore throat.

Other choices when it comes to the Best Teas for Immune System Health include Echinacea, Rosehip, Pine Needles and Lemon and Ginger Tea.

Is Fennel Tea Good for Weight Loss

Is Fennel Tea Good for Weight Loss?

We’ve already established that Fennel Tea is an appetite suppressant, which in itself provides assistance to those looking to drop a few pounds.

Then there are Fennel Tea calories - or, rather, it’s lack of calories. Indeed, this infusion tends to contain no more than two calories per 8-oz cup.

This makes it an excellent alternative to sugary, fatty soft drinks. But there’s more.

Preliminary (emphasis on “preliminary”) research suggests that it can boost the metabolism of fat cells. What this does, then, is enable the body to burn fat quicker and more efficiently.

Ultimately, this leads to periods of exercise producing better, perhaps even more noticeable, results. It won’t do all of the work for you, however, so be sure to maintain a healthy and active lifestyle.

Fennel Tea for Menstral Cramps

Fennel Tea for Menstrual Cramps

Many of the same qualities to Fennel Tea benefits that improve digestion can also alleviate painful menstrual cramps. This is according to an Iranian study using a combination of Fennel extract and Vitamin E.

It noted a dramatic reduction in cramping pain from menstruation following the consumption of this mixture. Participants also recognised it as more effective than over-the-counter pain relievers.

The reason? Its antispasmodic properties. These can relax the muscles in the uterus while relieving cramping, releasing muscle tension and soothing inflammation.

Yet please be aware that it has its limitations. As such, The Kent and Sussex Tea and Coffee Company once again urges caution when drinking this Tea for this purpose. Always speak to your doctor first before doing so.

Fennel Tea Benefits Skin

Fennel Tea Benefits Skin

Would you believe that the benefits of drinking Fennel Tea extend to skin health as well? It’s true.

Having Fennel Tea for acne, specifically, is a good idea because of its anti-inflammatory response. Its antioxidants also play a significant role in combating free radicals in the body.

Kaempferol and quercetin, in particular, fight several skin disorders. And that’s just the beginning.

Fennel Tea benefits skin health by acting as a toner. It likewise has anti-ageing properties, which reduces the presence of wrinkles, while also improving skin texture.

Nevertheless, it’s important to note that most research on the benefits of Fennel Tea for skin refers to its seeds. For this reason, we cannot in good conscience recommend it until more evidence surfaces.

Fennel Tea Side Effects

Fennel Tea Side Effects

Some of the chemical compounds found in this infusion, especially those related to its estrogenic properties, might lead to Fennel Tea side effects.

Perhaps most vital is to recognise the risk involved with drinking it to relieve menopausal symptoms. While its hormone-balancing abilities might help some, they could also, very potentially, cause health concerns in others.

This herb could likewise negatively interact with certain medications, including estrogen pills and certain cancer prescriptions. Furthermore, there is the possibility of it decreasing milk supply rather than increasing it.

Simply put, Fennel Tea benefits don’t work for everyone. You should, as a result, always seek medical consultation if you experience any of the above symptoms.

Fennel Tea Pregnancy

Fennel Tea Pregnancy

It’s sometimes advisable to err on the side of caution when drinking Herbal Tea while pregnant. Some beverages, including Liquorice Root and Sage Tea, can cause adverse complications in expecting mothers.

But what about this particular brew? Is Fennel Tea safe in pregnancy? Unfortunately, it is yet another example of an infusion you should avoid.

The reason is to do with its estrogenic properties. One study observed its influence on a pregnant woman’s body, concluding that it disturbed fetal growth and development.

It also noted that high doses might have toxic effects on fetal cells. Consider, instead, Raspberry Leaf Tea pregnancy benefits, which many midwives recommend during the third trimester.

Does Fennel Tea Have Caffeine

Does Fennel Tea Have Caffeine?

Around sixty plants naturally contain caffeine, a stimulating chemical compound capable of boosting energy. This includes Tea (Camellia sinensis), Coffee (Coffea) and that of lesser-known Yerba Mate (Ilex paraguariensis).

Fennel Herbal Tea, on the other hand, and as we’ve already mentioned, isn’t a “Tea” in the conventional sense. What it is, then, is a herbal infusion.

Due to its lack of so-called “real” Tea leaves, this beverage is 100% void of caffeine. As a result, if you’re looking for an extra kick in the morning, you’d be better off choosing another infusion.

If, however, you’re looking to cut down your intake, then it is an excellent choice. This is one of the reasons why so many caffeine-sensitive individuals flock to Fennel Tea!

How to Make Fennel Tea

How to Make Fennel Tea

And there you have it: Fennel Tea benefits and side effects backed with the latest research.

If you’re thirsty for more, all we can recommend is that you buy it and brew today. First, you’ll need to get a Tea Infuser or Filter (both of which we stock).

Once you have one to hand, as well as, of course, the Tea itself, be sure to follow these instructions below:

1. Use a Tea Infuser or Filter.

Put your Loose Leaf Fennel Tea into one of these accessories.

2. Boil the kettle.

Either filter or bottled water is best.

3. Put the Filter or Infuser into a cup or mug.

A porcelain mug has the least influence on the taste.

4. It’s time to add the freshly boiled water.

Fill your cup and mug with the water from the kettle.

5. Allow it to Infuse / Steep.

Let it brew for 5-10 minutes. The longer you leave it, the stronger it tastes.

6. Consider having additions.

Some people add honey or lemon, although it tastes best without any accompaniments.
