Cytisus scoparius (L.) Link Fabaceae. Common broom, Genista. Distribution: Western and central Europe. Culpeper (1650) writes: 'Genista. Broom: … clense and open the stomach, break the stone in the reins [kidneys] and bladder, help the green sickness [anaemia]. Let such as are troubled with heart qualms or faintings, forbear it, for it weakens the heart and spirit vital' and in respect of the flowers he writes: 'Broome-flowers, purge water, and are good in dropsies [now regarded as heart failure with fluid retention].'
