White horehound (Marrubium vulgare) is a flowering plant that is native to Europe, North Africa, and Asia. It is a member of the mint family and has been used for medicinal purposes for centuries. The plant has been naturalized in North and South America and is now considered an invasive species in some regions.
White horehound has a long history of use in traditional medicine, particularly for respiratory ailments such as coughs, bronchitis, and asthma. It is also used to treat digestive disorders, such as nausea, vomiting, and indigestion, as well as liver and gallbladder problems.
The plant contains various compounds that are believed to be responsible for its medicinal properties, including marrubiin, which has been shown to have anti-inflammatory, antioxidant, and antiviral effects. White horehound also contains essential oils, tannins, and flavonoids.
One of the most common uses of white horehound is for coughs and other respiratory issues. The plant has expectorant properties, which means that it can help to loosen and expel mucus from the lungs, making it easier to breathe. It also has antispasmodic properties, which means that it can help to relax the muscles in the airways, reducing coughing.
White horehound has also been used to treat digestive problems, such as bloating, gas, and stomach cramps. It is believed to stimulate the production of digestive juices, which can help to improve digestion and reduce inflammation in the digestive tract.

While more research is needed to fully understand its medicinal properties, it may be a useful natural remedy for a range of health conditions. However, as with any herbal remedy, it is important to speak with a healthcare professional before using white horehound, particularly if you are pregnant, breastfeeding, or taking medications.
