Quite a while back I learned a bit about using elementals to protect and to heal. This can be done with many herbs and fruits. To invoke the fearies, elves and elementals of a plant or fruit simply use this technique:
Place the herbs or fruit (it can be lemon squashed into a glass of water rank for health or any fruit you are about to eat) on the ground or floor with enough space to walk around it. Place your left hand on your solar plexus and your right arm pointed toward the floor with your index and middle finger erect in order to draw a circle as you walk around your herbs or fruit.
Begin to walk around the herbs or fruit and ask the Father to call upon the elementals of the herbs or fruit to help you. you can ask for protection or for good health. Walk around it 3 times asking at the same time. This should encourage the elementals of the fruit or herbs to come out and help you in what you have asked for. You can then eat the fruit but not the herbs.
