All the mixed colour sets of crystals for specific problems are purely for helping you to heal yourself. Each crystal has been chosen for its known ability to ease the symptoms of certain challenges we have to mind, body and spirit. Please bear in mind though that we are all different and crystals that have worked for others may not necessarily be right for you. Crystals are not meant to be used as a substitute for medical attention but complimentary to it. If you have any doubts it is always best to consult a qualified holistic practitioner or your doctor.
