A good Feng Shui stone, Prehnite is helpful for "decluttering", helping you to let go of possessions you no longer need, and to organize what you keep in appropriate way. It aids those who hoard possessions, or love, because of an inner lack. This may well come from past-life experiences of deprivation and poverty or lack of love. With Prehnite's assistance, trust in the universe is restored and the soul once again believes in divine manifestation.

Psychologically, Prehnite alleviates nightmares, phobias, and deep fears, uncovering and healing the disease that creates them. It is beneficial for hyperactive children and the karmic causes that underlie the condition.

Prehnite is useful for diagnosis, going to the root cause. It is healing for the kidneys and bladder, thymus gland, shoulders, chest, and lungs. It treats gout and blood disorders, repairs the connective tissue in the body and can stabilize malignancy.
