Pennyroyal helps us create stronger and clearer boundaries against psychic attacks. It can help us rid ourselves of old negative theme songs we play over and over again in our heads. It is useful in situations where the negativity is accidentally absorbed into our energy systems such as when we feel out of balance after being in a negative place. It also helps when we are aware that someone is sending us negativity and we do not want to be available to receive it. It is useful for clearing negativity from crystals or clothing and can be used in a plant mister to clear rooms of negativity. It is a versatile Essence helping us to establish appropriate boundaries.
