Fennel is easy to use and can be added to your daily routine in many ways:

• Chew fennel seeds after meals to freshen breath and help digestion.
  
  
• Make fennel tea by crushing 1 teaspoon of seeds and steeping in hot water for 10 minutes.
  
  
• Cook with fennel – use the fresh bulb in soups, salads, or roasted dishes.
  
  
• Use fennel oil (diluted) for massage to relieve stomach pain or gas.
  
  
• Add ground fennel to curries, baked goods, or herbal blends.
  
  

Make sure to use food-grade fennel if you’re consuming it, and avoid using too much oil without guidance.

Fennel works mainly through its natural oils, such as anethole, fenchone, and estragole. These compounds have many helpful effects on the body:

• Relaxes muscles in the stomach and intestines, which helps reduce gas, cramps, and bloating.
  
  
• Acts as a mild expectorant, which helps loosen mucus and reduce coughing.
  
  
• Contains phytoestrogens, which are plant chemicals similar to estrogen. This may help balance hormones in women.
  
  
• Has antioxidants, which protect the body from damage by harmful free radicals.
  
  

Fennel is gentle and safe for most people when used in moderate amounts.

Fennel is safe for most people, especially when used in food or tea. But high doses or long-term use may cause problems in some cases.
