These elements are essential for healthy bones, skin repair, and metabolism.

Anethole is a compound in fennel that suppresses your appetite and enhances metabolism, helping you to lose weight.
Natural Detoxifier and Diuretic
This sweet herb is a natural body cleanser and diuretic that helps to flush out toxins from your body, promoting better kidney health.
Improves Digestion
It contains compounds (fenchone and estragole) that stimulate digestive juices (in your gut) and improve digestion by relieving bloating, constipation, and gut spasms.
Manages Hypertension
Fennel seeds are rich in potassium and fiber and are great for high blood pressure and cholesterol, promoting better heart health.

Drinking soaked seeds (overnight) may alleviate menstrual cramps and promote menstrual flow.
Skin Repair
This versatile plant is rich in antioxidants, zinc, and selenium, which work together to give you firm, smooth, and flawless skin!
Tip: Make a face mask of fennel seeds (crushed) with honey or rosewater to reduce dark spots!

A 2020 study reveals this plant contains galactagogue (increases milk production) properties that stimulate breast milk flow.
Side Effects of Fennel – Take Precautions!
Fennel is POSSIBLY SAFE (for most individuals) when consumed in food amounts such as cooking and chewing a pinch of it as a mouth freshener after a meal.
However, their excessive consumption can cause some side effects.
Allergic Reactions
Fennel belongs to the same family as carrot, celery, and palsy. If you are already allergic to any of these, you should avoid taking it in your diet.
Fennel May Interfere With Your Hormones
Phytoestrogens, a compound in the seeds, mimic an estrogen hormone that can interfere with breast cancer, uterine cancers, and other gynecological conditions.
Sunburn
Cosmetics products containing fennel oil can make you sun sensitive and give you a suntan (or sunburn).
Fennel May Interact With Medicine
Its seeds may interact with medications (antibiotics and anti-epileptics).

Pregnant women should avoid taking fennel as it can stimulate their uterus and may cause premature delivery.
How to Grow and Harvest Fennel Effortlessly

Let me tell you, fennel is an easy herb, which means you can grow and harvest it effortlessly simply by following this complete guide.
Growing Fennel
- It grows best in a well-drained, fertile soil with a pH of 6.0-7.0 that welcomes full sunlight
- Add compost to prepare the soil
- Sow the seeds directly into the garden about 6-8 inches apart and cover them with a handful of soil (about 1/8 inch)
- Keep the soil moist but not soggy
- Thin seedlings will develop within 7-14 days
Tips:
- Protect your young seedlings from aphids and fungal infections using insecticidal sprays
- If you prefer growing fennel indoors, you can begin with a deep pot (about 15 inches) and four weeks after the last spring frost
- Remember to remove the pot before transplanting into your garden
- Be gentle with watering, as overwatering may rot the plant
Harvesting Fennel
Pick your favorite part from your homegrown fennel within approximately 70-100 days (count after the germination period).
Bulb
You can harvest the bulb in late summer or early autumn when it resembles the size of a tennis ball (about 3-5 inches).
I use a sharp knife to cut off the bulb from the plant’s base above the soil line.
Here’s a quick tip: Water your plant’s base well a few days before harvesting a bulb like a pro!
Leaves (Fronds)
The more you snip the leaves, the more you encourage your plant to grow! This technique also prevents the plant from bolting (a plant begins to produce a flower stalk and seeds prematurely).
I got my pruning shears to snip the leaves whenever needed, possibly in my stews, soups, and salad.
Seeds
You can harvest the seeds when the flowers turn brown.
My favorite part of harvesting is collecting its seeds. I prefer to wrap a loose-knitted thin cheesecloth around the flowerheads (the seeds will fall in cheesecloth when ripe), cut the stalk, and use the harvested seeds later.
Storing Fennel

Do you ever wish you could store your herbs and spices without doing anything yet still get the job done? Try my preferred and minimal-effort storage methods and elevate your cooking skills.
Refrigerate (Bulbs and Fronds)
After harvesting, I rinse the bulbs and fronds (leaves), pat them dry using a kitchen towel, wrap them in brown paper, and put them in my fridge door (to refrigerate). It’s that simple!
You can also freeze the bulbs and fronds using the same method (blanch them before doing a freezing method) and use them for up to six months!
Tip: If you prefer to freeze it, use freezer-safe bags instead of brown paper or plastic bags!
Drying (Seeds)
If you harvest the seeds (like I did), then it’s no big deal to dry them:
- Untie the knot from the cheesecloth
- Place the cheesecloth in an airy place in your home and let it sit for one week
- Once the seeds are dry, you can grind them into a powder or use them whole
- Store the seeds in airtight containers to retain their taste and aroma for a long time
Fennel Infused Oil
I used the infused oil (I prefer olive oil as a carrier oil) in my salad dressing and sautéed veggies for a subtle anise-like taste.
Fennel Tincture
As a mother of a boy who usually gets bloated, I used my DIY fennel tincture to relieve his bloating instantly.
How to Make Fennel Tincture
This tincture is a natural anti-bloating medicine that works magic on gastric issues:
- Place dried seeds in a jar
- Pour spirit, such as vodka, over them (enough to cover them completely)
- Close the jar tightly and shake it (until the mixture blends well)
- Store it in a cool, dark place for 4-6 weeks
- After six weeks, strain the mixture (using a strainer) into another glass jar
- Keep the liquid aside and throw out the seeds
- Transfer the tincture into an airtight, dark glass jar and use it for 2-3 years
Salve
I have been making herbal salves since I became a mother because they are gentle on my kid’s diaper rashes. It’s a great relief for any mother with an infant.
Tip: The fennel salve (I prefer seeds) is easy to make (in the same way) as I made the chamomile salve.
How to Consume Fennel
I am lucky to add homegrown herbs and spices to my recipes to get a quick kick of earthy flavors.
The sweet odor of fennel is welcoming, while the licorice-like earthy flavor gives an herbal note to my dishes. That’s how I celebrate this rich flavorsome herb!
Here are my preferred ways to consume it.
Infusion
Fennel infusion is a wholesome health supplement. Drinking a cup may aid in weight loss and reduce acidity.
I prefer to crush the seeds with a few drops of lime in two cups of boiling water to get myself in shape.
Decoction
Did you know you are an herbal lover when you put decoctions in the first place for your health?
Let’s make a fennel root decoction:
- Add one liter of water and two ounces of roots (chopped) to a saucepan and bring it to a boil
- Let the decoction simmer for half an hour on medium heat
- Turn off the heat and strain the solution using a strainer
Can I store the decoction in the fridge? The answer is yes, you can store the decoction in a sealed jar in the refrigerator (lasts for up to 1 week).
Roasted
There are some days when my family prefers to eat something light, and a roasted fennel bulb is a great choice!
On a lighter note, Its creamy and tender flavors are just scrumptious!
Fennel is an example of one delicious meal and remedy at a time!
