Meadowsweet is a flowering perennial herb that is native to Europe and Asia; it is one of the three most sacred herbs to the druids. It was used in many ceremonies, such as weddings and funerals. There is also speculation that it was used to flavor mead. In 1838 salicylic acid was isolated from meadowsweet and this lead to the development of aspirin. The word aspirin comes from meadowsweets old scientific name Spiraea.
Meadowsweet has been used for colds, respiratory problems, acid indigestion, peptic ulcers, arthritis and rheumatism, skin diseases, and diarrhea.
