Rosemary is quite stimulating and is heralded for help in memory retention and staying focused and alert. Rosemary is a good choice for blends for driving long distances and for long study sessions.
Safety Information: is phototoxic. Although the steam distilled essential oil is preferred for holistic aromatherapy and is the basis for this profile, it's prudent to mention that robert tisserand and rodney young also mention that anglica root CO2 and angelica root absulote are also possibly phototoxic.
