What effect does fennel oil have on the respiratory system?

Fennel oil is well known for its antispasmodic properties, which means it can help to relieve spasms in the respiratory tract. This is particularly beneficial for conditions such as bronchitis or coughs, where spasms can cause discomfort and difficulty in breathing. By relaxing the muscles in the airways, fennel oil can help to ease coughing fits and improve overall airflow, providing comfort to those with respiratory issues.

In addition to its antispasmodic effects, fennel oil can also have other potential beneficial influences on the respiratory system, but its primary and most significant action is its ability to calm spasms. This specific action makes it particularly useful in aromatherapy settings aimed at providing relief for respiratory distress.
