Frequently Asked Questions
Fennel is a widely-used herb in the culinary world, valued for its rich flavor and also recognized for its healing properties.
The history of fennel as a medicinal herb dates back to ancient times, with historical documentation from the first century A.D. recommending it for treating fevers.1
New findings suggest that the essential oil extracted from fennel could help the body combat inflammation triggered by air pollution.
Recent studies conducted in France have shown that phenylpropanoids, natural compounds present in various plants, can protect lung and liver cells from the detrimental effects of pollution particles released by sources like vehicles and power plants. One specific phenylpropanoid found in fennel, trans-anethole, has been proven to significantly reduce inflammatory markers in the lungs and liver.2
Fennel facilitates easier digestion by easing bloating, gas, and other gastrointestinal problems. It works by relaxing gastrointestinal muscles, reducing inflammation, and enhancing the secretion of gastric juices to aid in efficient food digestion and nutrient absorption.
Research involving postmenopausal women indicates that fennel can help alleviate symptoms like sleep disturbances, hot flashes, vaginal dryness, and anxiety. The essential oils of fennel possess phytoestrogenic properties that mimic estrogen, effectively addressing menopausal discomforts.
Studies suggest that fennel's natural melatonin content may assist in weight management by stimulating the production of calorie-burning beige fat cells. This can help in regulating blood sugar levels and enhancing overall metabolic health.
While fennel provides numerous health benefits, caution is advised when using it as a supplement, particularly considering its phyto-melatonin content and potential impacts on sleep patterns and mental well-being.
Fennel can also support stress management and cognitive function, potentially improving brain health and memory recall due to its antioxidant properties and ability to enhance neurotransmitters.
Opting for fennel as a natural food source is a great way to obtain essential nutrients. However, fennel supplements can be beneficial for addressing specific health issues, such as menopausal symptoms, with a note of caution for individuals taking certain medications.
