The name is from the Greek word signifying 'bee,' indicative of the attraction the flowers have for those insects, on account of the honey they produce. It was formerly esteemed of great use in all complaints supposed to proceed from a disordered state of the nervous system. The London Dispensary (1696) says: 'An essence of Balm, given in Canary wine, every morning will renew youth, strengthen the brain, relieve languishing nature and prevent baldness.' John Evelyn wrote: 'Balm is sovereign for the brain, strengthening the memory and powerfully chasing away melancholy.' Balm steeped in wine we are told again, 'comforts the heart and driveth away melancholy and sadness.' Formerly a spirit of Balm, combined with lemon-peel, nutmeg and angelica root, enjoyed a great reputation under the name of Carmelite water, being deemed highly useful against nervous headache and neuralgic affections.
Many virtues were formerly ascribed to this plant. Gerard says: 'It is profitably planted where bees are kept. The hives of bees being rubbed with the leaves of bawme, causeth the bees to keep together, and causeth others to come with them.' And again quoting Pliny, 'When they are strayed away, they do find their way home by it.' Pliny says: 'It is of so great virtue that though it be but tied to his sword that hath given the wound it stauncheth the blood.' Gerard also tells us: 'The juice of Balm glueth together greene wounds,' and gives the opinion of Pliny and Dioscorides that 'Balm, being leaves steeped in wine, and the wine drunk, and the leaves applied externally, were considered to be a certain cure for the bites of venomous beasts and the stings of scorpions. It is now recognized as a scientific fact that the balsamic oils of aromatic plants make excellent surgical dressings: they give off ozone and thus exercise anti-putrescent effects. Being chemical hydrocarbons, they contain so little oxygen that in wounds dressed with the fixed balsamic herbal oils, the atomic germs of disease are starved out, and the resinous parts of these balsamic oils, as they dry upon the sore or wound, seal it up and effectually exclude all noxious air.
