In ancient times, thyme was not always correctly identified (but Pliny, in the first century, mentioned thyme found in La Crau, France). Various thymes were recognized as having properties that were good for the digestive and respiratory systems, and they are still used in popular medicine in southern France. Thyme has been used as a herb for thousands of years and has now regained an important role in medicine due to its essential oil, which has antibacterial and anti-infective properties.
Thyme essential oil has purifying properties.
