Yarrow is the classic energetic shield protecting from outside energies and emotions. It creates the awareness between what belongs to you, and what you are picking up on from the atmosphere or other people's stuff. We often mistake and receive outside heaviness as our own, letting it weigh us down and wear us out. Yarrow is especially great for the empath or anyone who needs to function in charged environments, and has been documented long term for its use with EMF exposure, allergies, environmental illness and psychosomatic diseases.
