In earlier times, settlers would drink herbal horehound tea and also make tea from the bark and leaves of the white birch tree.
Authentic horehound lozenges are still sold today (mainly in Europe) but are difficult to find in the U.S. They are effective and much better than chemical lozenges that actually disrupt the body’s normal “expectorant” processes. Horehound does not put the delicate tissues to sleep as chemicals do. Horehound tea may be the closest thing that you can find in the U.S. Alvita Teas makes a good size box of horehound tea for a few dollars.
