Althaea Officinalis Extract is a natural treatment for whooping cough (pertussis), bronchitis, and other respiratory issues. It also relieves cough and sore throat. This is because both the blossom and the root contain significant amounts of mucilage. It is advised to take this herb for indigestion and diarrhea, as well as for peptic ulcers, hiatus hernias, mouth ulcers, enteritis, and colitis, which are all conditions associated with inflammation of the digestive tract.
