Lavender|Lavandula angustifolia

"In the Temple of King Solomon, lavender was one of the herbs used for aspurging. Lavender is a traditional aid in sharpening vision and clarifying thinking, which makes it an excellent herb for scholars (and exemplifies its Mercury aspect). Lavender is also good to incorporate into love magic (try the love magick incense recipe), and although it is often associated with chaste love, it is also connected to fertility and has been added to wedding cakes for that reason.  This magic herb is usually associated with midsummer festivals and is used to attract the Fae. Grind and add a little warmed elemi to make a great incense. 

In Herbalism 

This wonderful herb of Mercury and Air is well known and loved for its calming, antidepressent effects. The Romans brought lavender to Europe, planting it wherever they went so they might always have a ready supply (it’s tough running an empire). The dried flowers are the most powerfully scented part and can be used in herbal sleep pillows to help against insomnia, added to soaps for a gentle and fragrant exfoliation, or to bath water to decompress after a stressful day. Make a nice lavender oil by soaking the buds in olive oil for at least one Moon cycle (keep in a dark, slightly warm place while infusing). Or try flavoring some sugar by mixing some buds in and letting it sit for a week, then sifting out.” -Alchemy Works
