Crystal therapy was used in ancient times to help treat the body holistically for various ailments, and its use dates back to Egyptian times when it was said to be used to purge 'evil spirits.' Individual stones such as amethyst, rose quartz, and jade, according to the belief, has the ability to communicate with the energy flow of the human body and help to realign the energy channels that are interrupting the natural flow of the body, and help it heal itself. Specific stones in crystals are said to help relieve specific ailments such as anxiety, depression, and insomnia, as well as more physical ailments such as digestive problems. Wearing precious stones and minerals as bracelets and necklaces, placing crystals in the room where you work and sleep, or being treated by a crystal therapist who can identify which stones can work to stimulate the seven chakras, or 'energy points around the body, are all examples of crystal therapy. Each stone's electromagnetic charge is said to provide healing vibrations as it works to remove blockages around the body and restore a natural flow of energy.
