The littleleaf linden, also known as Tilia cordata, is a popular tree in parks and along roads. The dried inflorescences of the littleleaf linden, also called Tiliae flos, are used as a medicinal drug. Tea preparations made from the drug are often used for colds and coughs, as they have a cough-relieving effect due to their high content of mucilage, mainly arabinogalactans. Although the littleleaf linden is also used as a diaphoretic remedy for febrile infections, no specific ingredient has yet been found as an explanation. It is assumed that the sweating effect in this case is due to the ingestion of the hot tea water.
