MARRUBIUM 

Intrinsic humid asthma. Chronic bronchitis. 

White horehound is a well-known and popular herbal medicine that is often used as a domestic remedy for coughs, colds, wheeziness etc. The herb apparently causes the secretion of a more fluid mucous, readily cleared by coughing. The leaves and young flowering stems are antiseptic, antispasmodic, cholagogue, diaphoretic, digestive, diuretic, emmenagogue, strongly expectorant, hepatic, stimulant and tonic. Horehound is a very valuable pectoral, expectorant and tonic that can be safely used by children as well as adults. It is often made into a syrup or candy in order to disguise its very bitter flavour, though it can also be taken as a tea. As a bitter tonic, it increases the appetite and supports the function of the stomach. It can also act to normalize heart rhythm. The plant is harvested as it comes into flower and can be used fresh or dried. The root is a remedy for the bite of rattlesnakes, it is used in equal portions with Plantago lanceolata or P. major. medicinal herbs: WHITE HOREHOUND - Marrubium vulgare (naturalmedicinalherbs.net)
