What is Fennel Seed Water?

Fennel seed water is simply water infused with fennel seeds, either through immersing them in hot water or steeping it overnight in cool water. Fennel water has a light golden colour, smells fresh and clean, and the taste is not bad at all! In the beginning, I did find the taste weird but I got used to it real quick!

Fun fact: Fennel seeds or fennel water actually has a mild licorice flavor, so it leaves a sweet taste in your mouth, and is actually potent breath freshener!

Fennel Water Recipe for Weight Loss

Making fennel water is a simple task that doesn't require any complicated procedures.

Let's get right into the recipe. In my experience, you can make fennel water two ways:

  1. Brewing fennel seeds in boiling water and allowing it to cool
  2. Overnight steeping.


  • If possible, use distilled water, the purest form of water.
  • For extra aroma, roast the fennel seeds in a pan until it gives out a sweet toasted scent (only about 20 seconds of toasting on a heated pan is needed).
  • For beginners, consider starting out with a smaller dose of seeds by using half the amount in the recipe. Work your way up as you get used to it.

How to Make Fennel Seed Water



  • 1 liter or 4 cups of drinking water
  • 2 tablespoons of raw fennel seeds


  1. In a deep pan, bring the water to a boil. You can use hot water straight out of your kettle too.
  2. When the water starts bubbling, toss in the fennel seeds, and switch off the flame immediately.
  3. Cover the pan with a lid and allow this to cool to room temperature.
  4. Once it cools, your fennel water is now ready! All you have to do is to transfer it into your glass jar or bottle and drink it throughout the day.
  5. You can even make larger batches and store in the fridge if you don't have time to make a fresh batch everyday. Simply double the recipe above.


Lately I've been preferring the overnight steeping method for making fennel water. It's easier for me to prepare fennel water at night so I don't forget in the morning as I'm in a rush to head out the door. Also, it doesn't apply heat so the nutrients in the fennel seed have no chance of being destroyed. Lastly, it requires less utensils so I have less washing up to do!

In this method, all you have to do is:

  1. Get a glass jar, add in 2 tablespoons of fennel water and fill it up with 1 litre of water.
  2. Then, cover it with a lid and you can forget about it until the next morning.

At first the seeds will be floating at the top, but by morning the seeds will be engorged with water and will have sunk to the bottom.

How It Helps You Lose Weight

  1. It increases metabolism. Metabolism refers to the rate at which our cells use up energy from the food we eat. By boosting metabolism, calories in food are burned off faster in the body, aiding in fat loss.
  2. It is a natural appetite suppressant. Thinking of purchasing artificial appetite suppressing tablets? Consume natural fennel seeds instead. Chewing on fennel seeds helps naturally quell appetite.
  3. The seeds aids in blood purification. Fennel seed water helps clear out excess uric acid in the blood stream and breaks down bile. It promotes digestion of fats in the liver as well.
  4. The water helps to detoxify the body. In today's world, we are bombarded with toxins from every angle, from car exhaust fumes to cosmetic products. This drink helps flush out the toxins in the blood stream via the kidneys.
  5. It is mildly diuretic. Fennel seed water has a mild diuretic effect and can help you keep alert and awake, minus the caffeine! Sipping the water throughout the day can help you keep alert and awake, giving you just enough motivation to get up and exercise, without the usual caffeine crash.
  6. An anti-spasmodic effect. The anti-spasmodic effect of fennel helps suppress hunger pangs by relaxing the stomach muscles that produce the sensation. This can help you intake less calories and lose excess weight.
  7. It stimulates melatonin. Melatonin is a natural hormone produced in the brain by the pituitary gland, which is responsible for regulating sleep. A good night's sleep of 6-8 hours is crucial for healthy weight loss and can help maintain healthy weight levels as well.

How Much Should I Drink?

As much as fennel water is a great drink for weight loss, it does not mean that the more your drink of it, the more weight you lose! In fact, as with all things, everything should be done in moderation.

  • Follow the recipe given and make one batch of 1 litre or 4 cups per day and sip throughout the day. Take your weight loss on a day by day basis.
  • If you are worried of any adverse symptoms, begin with one cup of fennel water per day and see how you react to it. You can the build up to 4 cups per day gradually.
  • Always consult your health care practitioner.


Although this is an all natural remedy, it's best to always consult your health care practitioner before undertaking any new healthcare regimen, especially if you have any known adverse health conditions or allergies. Pregnant women may want to avoid fennel or fennel water altogether.

      Nice hub. I always eat fennel seeds as a mouth fresher but didn't know other benefits earlier. One of my friend keeps chewing fennel seeds all day. Does over eating has any side effects? And is eating fennel seed has the same benefits as

      fennel water ?

      Hello, preweb! I believe fennel infused tea or fennel water is the remedy for weight loss in particular. Water has zero calories and fills your stomach and the fennel in fennel water has many properties that help suppress appetite.

      As for your second question, is it possible to overdose on fennel seeds? The answer is, too much of anything can be bad for you. Eating a teaspoon of fennel seeds after every meal, for breath freshening is quite enough. You wouldn't need to eat fennel seeds more often than this.

      Hope you found this helpful!

      Wow, I am grateful for this hub: This reaffirms why I started drinking this and fenugreek tea/water in the morning to detox for better health (I am fascinated with herbal medicine from all cultures!). I definitely feel more energized and leaner when fenugreek and fennel seeds are in my diet.

      Also, although I completely agree that everyone should do their own research and make educated/informed decisions when starting a new "diet", did you know that after pregnancy fennel and fenugreek is good for you? Apparently it increases lactation/milk production and balances hormones out!

      I've been eating fennel after each meal now for the past week and a half. I've also included drinking warm/hot water in my diet. This helped me loose about an inch on my belly without changing the way I eat or consume food. This does say something I guess..

      6. Relieves Menstrual Problems

      Many factors, including stress and poor diet, can interrupt a woman’s regular menstrual cycle. Fennel seeds have emmenagogue properties that promote and regulate menstrual flow. The herb also has phytoestrogens that help with issues like premenstrual syndrome, menopausal disorders, and breast enlargement.

      A 2012 study conducted by researchers from Babol University of Medical Sciences and Health Services in Iran also indicates that fennel can help reduce symptoms of dysmenorrheal or painful menstruation.

      Apart from menstrual benefits, fennel is traditionally used as a galactagogue to promote lactation in nursing mothers. It also works as an aphrodisiac to increase libido in both men and women.
