Remarks : | Several species, especially common self-heal (Prunella vulgaris), large-flowered self-heal (P. grandiflora), and cutleaf self-heal (P. lacinata), were regarded in medieval times as cure-alls and are still used in herbal medicine. The dried leaves and flowers are commonly brewed for soothing sore throats.
This downy creeping perennial rarely grows taller than 30cm and often the flower heads are no more than 5 to 10cm above the ground. A distinguishing feature of this plant is the shape of its leaves, which are very deeply lobed, often with cuts almost to the central vein. |
