White horehound is used for digestion problems including loss of appetite, indigestion, bloating, gas, diarrhea, constipation, and liver and gallbladder complaints. It is also used for lung and breathing problems including cough, whooping cough, asthma, tuberculosis, bronchitis, and swollen breathing passages.
Women use white horehound for painful menstrual periods.
People also use it for yellowed skin (jaundice), to kill parasitic worms, to cause sweating, and to increase urine production.
White horehound is sometimes applied to the skin for skin damage, ulcers, and wounds.
In manufacturing, the extracts of white horehound are used as flavoring in foods and beverages, and as expectorants in cough syrups and lozenges. Expectorants are ingredients that make it easier to cough up phlegm.
