Oil of rosemary has the carminative properties of other volatile oils and is an excellent stomachic and nervine, curing many cases of headache. It is employed principally, externally, as spiritus Rosmarini, in hair-lotions, for its odour and effect in stimulating the hair-bulbs to renewed activity and preventing premature baldness. An infusion of the dried plant (both leaves and flowers) combined with borax and used when cold, makes one of the best hair-washes known. It forms an effectual remedy for the prevention of scurf and dandruff.
