Food Uses of Brooklime
Bitter-tasting brooklime can be eaten like watercress by adding raw to salads or cooked like a potherb by boiling or steaming.4 This wild edible is best mixed with strongly flavoured greens to compensate and complement its bitterness.5
Brooklime can be brewed as a tea, called tea de l’europe (or European tea), which has a flavour similar to Chinese green tea.5
Brooklime is rich in vitamin C3 and antioxidants such as flavonoids and phenolics, which help to reduce incidences of chronic disease when eaten as part of our diet.6 Some studies suggest European brooklime also contains 3.8 g of protein per 100 g of fresh weight.7
Herbal Medicine Uses of Brooklime
Today we know that the plant contains vitamin C, as well as a glucoside (aucubine) and various other substances, such as sulphur.3
A brown dye is derived from brooklime for dyeing textiles.4
The plant is safe if cooked. Although it was eaten raw in the past, due to liver fluke it is best avoided raw.
