Thyme is used as an expectorant in coughs associated with cold, catarrh of the respiratory tract, bronchitis and dry cough.
Antispasmodic and expectorant activity. Thyme has spasmolytic activity in the airways, which justifies its use as a cough suppressant. Thyme also has expectorant activity, because its essential oil causes a thinning of bronchial secretions and promotes their elimination.
Antiseptic activity. Thyme oil has antibacterial activity. This effect is due to its action on the bacterial membrane. It is also of interest as a urinary and oropharyngeal cavity antiseptic, and for cleansing wounds.
