Prehnite is a very protective stone and can protect one on all levels. It strengthens the life force and generally increases and stimulates energy, while at the same time bringing powerful calming energies. Thus, prehnite is said to ease worries and restlessness of all kinds. It aids spirit communication through meditation or visualization, out-of-body travel, and is a powerful dream stone. Prehnite is also known as a stone of prophecy which stimulates inner-knowing. Physically, prehnite is helpful in the healing of gout, anaemia, and kidney problems. If dark strands are present within the Crystal this is Epidote.
