Mugwort has been known for ages as a reliable dream enhancing plant. I have also had good results with this mild herb that is a close relative of wormwood and has a long history of medicinal use.
In the West, mugwort was historically associated with the Greek goddess Artemis and the moon, perhaps because it stimulates blood circulation and was used chiefly to aid painful and irregular menstruation.
Of course, Artemis is one of the Greek Gods who was known to send divine dreams. In other words, mugwort, dreams and the Moon are all bundled together in an aromatic and cosmic smudge stick.
I recommend picking fresh mugwort consciously and ritualistically and placing it close to the bed, or even under your pillow before bed. Also try burning some mugwort as incense (and even smoking it – very pleasant), which can make bedtime into a ritual that will support more dream remembrance.
