Fennel Seeds Benefits & Medicinal Uses
Fennel seeds are mainly used for problems related to the digestive system. Secretolytic property helps in respiratory diseases. Antispasmodic action relieves cramps and abdominal pain. Its beneficial effects appear on stomach, intestines, liver, brain, heart, kidneys and uterus. Health Benefits of fennel (Foeniculum Vulgare) include its ability to preclude abdominal diseases, prevent gas formation and to help in weight loss, indigestion, cancer, and aging. It improves strength and promotes longevity.
Fennel seeds are one of the important medicines used for treating inflammation of the stomach. Fennel seed powder is commonly used to treat gastritis symptoms. It modulates the secretions of gastric acid and soothes the mucosal lining of the stomach. According to ayurveda, it actually does not reduce gastric secretions, but it reduces the TIKSHNA GUNA of PITTA (abnormal sharpness of gastric acid that causes inflammation in the stomach). Therefore, it does not likely to reduce appetite. Instead, it is likely to increase appetite. Many patients with gastritis, indigestion, heartburn, acid reflux or GERD have loss of appetite. In such cases, it also works to improve appetite due to modulation action on gastric secretions.
For best results in gastritis or heartburn, it can be used along with licorice root powder (Mulethi Churna), amla powder (Indian Gooseberry), and coriander seed. All these herbs should be mixed in equal proportion. The dosage is 1 teaspoon twice daily in between the food.
Indigestion (dyspepsia) is a condition related to GERD, ulcer and other underlying diseases. Fennel exerts similar action to reduce burning sensation in the abdomen. The carminative action helps to relieve belching and gas. The antispasmodic action helps to alleviate abdominal pain. Its antiemetic action helps to cure nausea and vomiting. It has gastric secretion modulation action, which helps to reduce acidic taste and sour taste in the mouth.
Polydipsia (Excessive Thirst)
Like cardamom seeds, Fennel seeds are also beneficial for reducing excessive thirst. It is commonly used for this purpose in ayurveda. For reducing excessive thirst, its seed powder can be mixed with brown sugar (Shakkar) or rock sugar (Misri) in equal proportion and taken with water. Alternatively, Fennel seed distillate (Saunf Arq) or fennel water in a dosage of 60 ml thrice daily can also be used.

Fennel Seeds for weight loss
However, fennel seed is wrongly stated as an appetite suppressant. It does not reduce or suppress your appetite. According to ayurveda, it normalizes appetite and improves digestion. If you suffer from loss of appetite, then it will increase your appetite. We have a huge experience on this using it in many of our patients to improve their appetite. Actually, it keeps your appetite as natural as it should be and helps you to have a good appetite. If you have loss of appetite, then it will help to modulate gastric secretion and improve liver functions, which ultimately normalizes your appetite. In fact, it acts as a gastric modulator, so it balances the secretion, as discussed under heading ‘Gastritis’.
The effect on obesity is due to its effects on metabolism and on the usability of the fats. It also induces burning of the accumulated fat. However, its effects as fat burner are not comparable with most of the ayurvedic medicines used for weight loss.
Fresh Fennel for losing weight
Fresh fennel is a low calorie, low fat, and a high fiber vegetable. 100 grams of raw fennel contains 30 to 35 calories and approximately 3 to 4 grams of dietary fiber. Such a composition adds bulk to the diet without increasing the overall calorie intake.
When fresh fennel is consumed, dietary fiber enters into the stomach, absorbs water and becomes viscous. Thus, it provides satiety and makes one feel full. This further reduces overall food intake and entry of calories into the system. Hence, consuming a big bowl of fennel salad before meals can be a great strategy for weight loss. (6)
Protects against Osteoporosis
Fennel is an anti-osteoporotic and osteoprotective plant because of its estrogenic property. Estrogen plays a vital role in the regeneration of bones. A low level of estrogens in the blood is associated with increased risk of osteoporosis. As fennel mimics the effect of estrogen, it protects the bones against fracture and strengthens them. Thus, fennel enhances overall bone health and lowers the substances that cause breakdown of bone tissue. (7)
Hirsutism (Excessive Hairiness)
Presence of male pattern hair in women is known as hirsutism. Such a condition is due to rise in the level of testosterone (male hormone) in females. Fennel contains Anethole, a compound that possesses estrogenic activity. It inhibits the conversion of testosterone into its active form. Thus, it weakens the action of testosterone in females and reduces hirsutism too. (8)
Studies have found that fennel protects vision loss. It helps in reducing eye pressure which otherwise increases the risk of cataract and blindness. Diabetic retinopathy (vision loss in diabetes) is a complication of hyperglycemia.
Anethole, an active compound present in fennel helps in normalizing blood glucose level and thus reduces the risk of vision loss. Furthermore, Anethole increases soluble lens protein and slows down the onset of cataract.
The antioxidant potential of fennel protects the eyes against free radical damage and thus enhances overall vision. In addition to this, healthy compounds present in fennel inhibit the action of aldose reductase and hence, it prevents damage to the eyes and nerves. (9)
Fennel is a strong antioxidant agent. It scavenges the free radicals and protects the red blood cells (RBCs) against free radical attack. It further enhances overall kidney health and promotes the formation of erythropoietin, an important factor required for the production of red blood cells. Low red blood cell count and low hemoglobin in the blood leads to anemia. As fennel enhances the production of RBCs, it helps in the prevention of anemia. (10)
