These seeds possess unique carminative and anti-spasmodic properties that enable them to treat severe gastrointestinal disorders such as Irritable Bowel Syndrome (IBS). According to studies, fennel seeds might also be particularly useful in treating diarrhea, constipation, ulcerative colitis, and Gastroesophageal Reflux Disease (GERD).

Help Lactating Women

Fennel seeds contain a compound called anethole. Anethole is a phytoestrogen (dietary estrogen) that mimics the estrogen hormone and its properties and enables the increased production of milk in lactating mothers. Therefore, for mothers breastfeeding, these seeds are a great way to ensure that their body is producing enough milk to sustain their child’s needs.

Bad breath is a common issue many of us struggle with. A quick and easy way to rid your mouth of any compromising odor is to chew fennel seeds. Their anise scent and flavor are refreshing and fast-acting. All you need is 8 to 10 seeds, and your breath will be freshened up in a few munches.

Help Combat Diabetes

According to a research study, fennel essential oil can lower blood sugar levels in diabetic patients. Fennel seeds are an excellent source of vitamin C, which is known to have significant effects in reducing blood glucose levels.  Since fennel seeds are a low glycemic index, they are a fantastic addition to a diabetic patient’s diet. Additionally, another antioxidant found in fennel seeds, beta-carotene, has also been associated with reduced cholesterol levels in patients with type 2 diabetes.

Reduce Cholesterol Levels

The beta-carotene present in fennel seeds helps to reduce the cholesterol levels in patients with type 2 diabetes. In addition to beta-carotene, the fiber in fennel seeds prevents the reabsorption of cholesterol. This mechanism enables the binding of bile salts which consequently prevents heart-related disorders. This, with other cardio-protective vitamins such as folate and vitamin C, thereby reduces the risk of hypercholesterolemia and cardiovascular issues such as atherosclerosis, stroke, and cardiac arrest.

Cure Edema

Edema refers to the swelling of tissues in the body owing to the buildup of excess fluid. While the correlation between the effect of fennel seeds and curing edema is not absolute, studies suggest that the compound responsible for the task is anethole. Anethole possesses the unique ability to control one’s blood pressure, flush out excess water from the body, and also helps improve kidney functions by facilitating the flushing out of toxins.

Help With Fertility Problems

The estrogenic properties of fennel seeds have been proven to help women who are breastfeeding. While the complete effect of fennel seeds on fertility is not yet established, studies and experiments have revealed that tea made from these seeds, in particular, might play a role in enhancing fertility and even induce labor in pregnant women. These same estrogen-mimicking properties allow fennel seeds to alleviate menstrual problems such as cramps and hot flashes.

Fennel seeds have been known to aid in the reduction of blood pressure levels. This is mainly attributed to their high potassium content. Potassium counteracts the effects of sodium and helps keep the fluid amount in the bloodstream in check. Fennel seeds are potent sources of calcium as well. Calcium is a mineral imperative for optimum blood pressure regulation. It helps keep blood vessels toned and also helps maintain heart rate. Additionally, these seeds have the greatest content of nitrites in them. Nitrites are compounds that are known to reduce blood pressure levels in the body.

Obesity is a rising global concern that is contributing to the subsequent increase in disease. Fennel seeds are rich in fiber and thus are excellent tools to help lose weight and keep hunger pangs at bay. They have also been reported to reduce fat-storage by helping improve nutrient absorption. Seeds of the fennel plant possess unique diuretic properties that increase urine output and flush out the excess fluid from the body. Several experts believe that this mechanism has a link to weight loss. Thus the weight loss said to have been caused by fennel is largely water loss and not because of fat loss.

According to a Korean study, fennel seed intake can help reduce appetite in overweight individuals. Another study revealed that partakers who added 14 grams per day of fiber to their diets, without changing anything else, ate approximately 10% fewer calories per day and lost about four pounds over a period of four months. Increasing fiber intake by adding high fiber foods to the diet, such as fennel seeds, maybe a simple way to feel more satisfied effortlessly and experience weight loss.

Help In Treating Candida

Candida is caused by a range of microorganisms but most prominently by E.Coli and Candida Albicans. Fennel seeds can aid the treatment of candida owing to their antibacterial and anti-fungal properties.

The anti-fungal benefits of fermented fennel seeds are extremely useful in combating candida, so much so that merely consuming a tablespoon of these seeds with your morning meal can help ease the symptoms of the disorder. An alternative way to have them is in the form of fennel seed-infused tea in the morning.

The perfect way to tone your skin would be to allow a handful of fennel seeds to infuse in hot water.

Fennel seed steam has been known to help reduce skin texture. Texture makes the skin look more mature than it is in reality. It is crucial to keep the skin clean, hydrated, and moisturized for hydrated, supple, and youthful-looking skin. Therefore, if you are battling skin texture, fennel seed facial steam can help clean your pores, hydrate your skin, exfoliate, and thus glow from within.

In addition to their anti-microbial properties, fennel seeds are rich in vitamin C. Vitamin C is an antioxidant that retards premature skin aging resulting from free radical damage. Also necessary for collagen formation, vitamin C intake is critical for preventing fine lines and wrinkles.

Prevent Hair Problems

Whether it is an itchy scalp, dandruff, hair breakage, or hair fall, fennel seeds can help you fight them all. The anti-microbial properties of these seeds, much like skin problems, help boost hair health. Washing your hair with fennel-infused water is excellent for repairing hair damage as well as preventing hair fall. For an itchy scalp, a concoction of fennel seeds, apple cider vinegar, and glycerin can make all your hair woes go away.

Boost Bone Health

The high calcium content in fennel seeds makes them an excellent choice to improve bone health and strength. In conjunction with the other elements found in these seeds, such as magnesium, phosphorous, and vitamin K, fennel seeds are great for your bones.

Side Effects:

While fennel seeds harbor countless benefits, they are not the best for people battling certain medical conditions or allergic to them. Their high potassium content deems them unsuitable for anyone battling kidney disease. Thus these seeds should be consumed in a limited amount. Patients on beta-blockers are also likely to have elevated potassium levels in the body.  Beta-blockers are drugs that are generally prescribed for controlling blood pressure. Thus patients who take these medicines should avoid these seeds to prevent any unfortunate outcomes.
