I can take it or leave it.. was never a great favorite with me, and havent had any in years. My Dad liked it. Here is a little info about the plant.
Natural Remedy
White horehound is used as a traditional folk medicine ingredient and administered in tea and lozenge form. It is thought to relieve asthma symptoms, calm sore throats, and lessen coughing caused by a cold or influenza. Many people use it to relieve digestive issues as well, as it is also thought to stimulate the appetite and to relieve gas. When used as a natural remedy, horehound candy is generally believed to be well tolerated in small doses, although hard candy is a choking hazard for small children.
Pregnant woman, lactating women, and children under two should not use horehound. The natural volatile oils of the plant can prevent the absorption of iron and other minerals, and may cause complications during pregnancy.
Growing the Plant
Although white horehound is native to Europe, Asia, and North Africa, it thrives in most climate zones, especially those found in the United States and Canada. In fact, it's considered by many to be an invasive species and a weed. The plant grows well in poor, sandy soils, and it is very tolerant of drought. It prefers full sun and drier conditions. Like other mint plants, it can spread easily.
When used to make candy, it's best for gardeners to wait until the second year to harvest the leaves and small, white flowers. A few leaves — no more than one-third — can be removed during the first year of growth, but harvesting too many can damage the plant. Once the horehound is well established, however, the leaves and flowers can be picked when they are at their peak, dried, and stored in an air-tight container for up to one year.
