Thyme

Improves mucociliary clearance & relaxes certain organs – although the mechanism is not entirely clear, this study showed that Thyme had a relaxing effect on organs that had beta2-receptors (i.e. the uterus and the trachea) and is modulatory in it’s effect, and that it improved mucociliary clearance.
