Horehound Blend contains herbs that strengthen the lungs and aid expectoration, helping to open the airways for easier breathing. While Over-The-Counter (OTC) medications tend to suppress all coughs, the Horehound, Mullein and other herbs in this blend work as expectorants, supporting the bodys natural desire to rid itself of excess mucus. Note: When excess mucus is present, try eliminating dairy and other mucus producing foods such as wheat and sugar. Facial steams and humidifiers can also help loosen congestion. Available in a 1 ounce liquid.
