Thyme (Thymus vulgaris)


Also known as the "whooping Cough herb," thyme acts to inhibit smooth muscle spasms and excess mucous production throughout the respiratory system. Used in kitchens all over the world, thyme also adds flavour to food and is enjoyed as a tea. Thymol, its primary component, acts as a disinfectant to rid the body of bacteria, viruses and fungi. Thyme?s volatile oil, composed of thymol and other constituents, prevents smooth muscle spasms and aids in proper gastrointestinal function. The low toxicity of the herb has made it a favourite for treating coughs in children.

It is also traditionally recommended for whooping cough and gastrointestinal irritations. Thyme oil has been used to treat fungal Infections on the Skin and to prevent gingivitis.
