Lemon as a purifier.. .

To rid yourself from parasitic vibrations gathered from the contact of hostile people, prepare a hot bath, it should be done during the full Moon, and press seven lemons that you have previously cut in four lengthwise, into the water. Get into the tub and rub yourself with the lemon peels, all over your bod. After the bath, the peels should be thrown over your shoulder and into running water.

Added to the purifying symbolism of water, the since Antiquity renown purifying and astringent agents of lemon, make it a so efficient liquid that it is even recommended for the cleansing of magic tools after their utilisation.
