Health Benefits of Fennel Seeds

1. Supports Digestion

Traditionally chewed after meals, fennel seeds help stimulate digestive juices, reduce bloating, and prevent constipation. Their natural oils relax the muscles of the gastrointestinal tract, making them a go-to for stomach discomfort.

2. Aids in Weight Management

Infused water or tea made from fennel seeds can curb hunger and promote satiety. Since they are high in fiber, they help control overeating and assist in maintaining a healthy metabolism.

3. Promotes Heart Health

The potassium and fiber content may help regulate blood pressure and reduce cholesterol levels, lowering the risk of heart disease.

4. Good for Skin

With plenty of antioxidants, fennel seed tea or water helps fight oxidative stress, which can prevent acne, wrinkles, and dullness.

5. Balances Hormones

The phytoestrogen compounds naturally present in fennel can help ease PMS and menopausal symptoms.

6. Boosts Immunity

Packed with vitamin C and antioxidant compounds, fennel supports the immune system and helps protect against infections.

7. Eases Respiratory Issues

Herbal teas made from fennel seeds are often used to relieve cough, congestion, and mild asthma symptoms due to their anti-inflammatory properties.
