Fennel Seeds (Foeniculum vulgare): Digestive, Respiratory & Heart Support
Fennel seeds are a nutrient-rich spice traditionally used in Mediterranean, Indian, and Middle Eastern medicine. They are valued for their digestive, respiratory, cardiovascular, and women’s health benefits, along with antioxidant and antimicrobial properties. Fennel seeds contain fiber, volatile oils (anethole, fenchone, estragole), potassium, and antioxidants that support overall wellness.
