Mental Power oil is for when you need the extra mental edge. Anoint the forehead and temples before studying, writing, public speaking, chess games, etc. Focus herb: Clove bud

Mental Power is a function of the planet Mercury, which rules all matters of study, intellect, and science. Therefore I make Mental Power on the Wednesday following the New Moon. It smells interesting, bright, and alert. Rosemary is very much believed to help mental clarity and memory, so it is one of the main scents of this oil, as is Clove. Clove buds are also powerfully antioxidant, and you can see the Doctrine of Signatures in this herb: the little bud, which is the flower of the plant, looks like a little stick figure with a very large head.

You can anoint yellow or purple candles, or a skull candle, with Mental Power oil to help you write or study. Try it on your temples and forehead to activate the frontal lobes!
