If one is a witch who doesn't know of Mugwort? It is one of my favourite herbs and I now have 2 plants growing!! Yay! I'm infusing some (thrice like the Wormwood oil) for my store. The Mugwort I am using is wildcrafted and is the whole plant not just the leaves.
Here it is steeping in the sunlight.
Next to it is the Wormwood. It has probably been infusing longer than necessary but it should pack a punch.
Mugwort is an ingredient in Flying Ointment also, and will be in mine when I eventually make some for my store. I always use Mugwort in anything psychic related and have some in a bag with my pendulum to both protect and cleanse it.
