MEDICINAL USE OF HOREHOUND
Horehound is, unfortunately, no longer a commonly used herb. Herbalists use it to soothe respiratory and digestive complaints.
The bitter compounds and the saponins regulate the secretion of the submucosal glands (glands that secrete mucus) in the air passages. They also lose and thin mucus acting as an expectorant, antiphlogistic and antispasmodic. It works wonders for bronchitis, especially in the elderly as well as pertussis and asthma.
It helps lower fever caused by malaria.
The antibacterial tannins in horehound counteract diarrhea and stimulate wound healing.
The bitter compounds also regulate the digestive system, particularly the gallbladder, lending strength to the body.
Take internally for:
- Fevers (especially those associated with Malaria)
- Gallbladder support
- Stimulating the appetite
Topic application for:
- Wounds and other skin conditions
Recommended daily dosage

Horehound has been used in Europe as a condiment to flavor salads, chicken and fish, soups and stews, sauces, strong-tasting vegetables, candy, cakes and cookies, ice-cream, liqueur and as a substitute for hops in beer (horehound ale).
