Rosemary is a circulatory and nervine stimulant, which in addition to the toning and calming effect on the digestion is used where psychological tension is present. This may show for instance as flatulent dyspepsia, headache or depression associated with debility. Externally it may be used to ease muscular pain, sciatica and neuralgia. It acts as a stimulant to both the hair follicles and circulation in the scalp and thus may be helpful in premature baldness. The oil is most effective here.
