Stinking mayweed, also known as dog fennel, is a type of herbaceous plant that is native to Europe and parts of Asia. This plant is known for its strong odor, which has earned it its unpleasant name. However, there are several synonyms for the word "stinking mayweed" that are less derogatory. Some of these include mayweed chamomile, scentless chamomile, wild chamomile, and false chamomile. These names focus more on the plant's appearance and uses, rather than its smell. Despite its less-than-pleasant scent, stinking mayweed has been used for centuries in herbal medicine and is still cultivated for its various medicinal properties.
