It has been introduced and has become naturalized in many countries around the world with suitable climate. Horehound is easy to cultivate and can be propagated by seeds or cuttings.
The plant thrives in a nutrient-poor soil in sunny and dry habitats. Like most plants in its family, it can flourish in wastelands and can be commonly found along roadsides.
Description: White horehound is an herbaceous perennial plant with grayish leaves, and grows to an average height of 33 cm. The leaves are 3 to 5 cm long with a hairy texture.
The flowers appear on the upper portion of the main stalk in small white clusters. The plant has an odd musky smell which lessens with dehydration.
Plant Parts Used: The young shoots and the leaves are the most commonly used parts of the white horehound. The above-ground parts of the plant are collected when it’s in bloom.
The herb is used fresh or dried for later use. It is used in the form of liquid extract, tinctures or powder.
In the past, the herb was mostly collected from the wild but today it is cultivated for commercial use in Hungary, Poland, Germany, Canada, and Finland.
