With their roots in the water along the edge of a local canal, these Yellow loosestrife (Lysimachia vulgaris) plants were so exuberant and lush I initially thought they were some other species. They had obviously found the damp niche that suited them best.

Though I would never advocate the use of herbal medicine (just being cautious about matters I don’t understand or have knowledge of), Yellow loosestrife did, apparently, have a large number of traditional uses as a medicinal plant, from treating diarrhoea and haemorrhaging to cleaning wounds and being used as a mouthwash. And the First Nature website reports on other common uses:

Yellow Loosestrife tied around the necks of oxen was reputed to keep irritating flies away from them. In the distant past these and several other kinds of ‘loosestrife’ plants were also used to get rid of infestations of flies in houses. The plants were dried and burned indoors, and toxins in the smoke drove out the flies (and no doubt also any human occupants).
