The original sign for a pharmacy or chemist shop, before the green cross, was an illustration or carving of coltsfoot aka Coughworth (Tussilago Farfara)

That plant has a long herbal tradition of suppressing coughs, expelling mucus and soothing irritated membranes. The roots as well as the buds, flowers, and leaves were all utilised in preparations to deliver mucilage and a demulcent action.
