Naming

The Latin name of waterhemp is Eupatorium perfoliatum . In Dutch the plant is called waterhemp and liverwort. Eupartorium is probably derived from ‘hepar’ which means liver in Latin. Perfoliatum literally means: leafing through and figuratively: continuing to grow. The plant is called waterhemp because it likes damp places. It is called hemp because its European cousin, royal weed, has leaves that are very similar to those of the cannabis plant. In the US the plant is called boneset and that refers to its beneficial effect on the bones. For example, it helps with dengue fever or dengue.

Waterhemp in history

Dioscorides, pioneer of medicine and herbal science from the first century BC, mentions waterhemp as a liver protectant in his book Materia Medica. By the way, Dioscorides had a variety in mind, namely the Eupatorium cannabinum or queen’s herb. Indians in North America knew waterhemp as a medicinal plant. They used it to sweat out a fever. It was also used for typhoid fever and mucosal inflammation.

Waterhemp for flu

The diaphoretic, antipyretic and analgesic effect are mainly responsible for this medicinal property. Furthermore, it is a laxative, an expectorant, which means that mucus is loosened and it is a stimulant for the immune system. For these reasons, waterhemp is used in phytotherapy for:
