Chalcanthite is an excellent throat chakra stone. It is said to help further desires through communication abilities. It is also said to help one stay in the now and enjoy life, as well as get rid of feelings of abandonment. Chalcanthite is reputed to eliminate delays of things in progress. It is also used metaphysically for insight, clairvoyance, and psychic attunement. It is said to enhance one's ability to "read" people and situation. Physically Chalcanthite is said in crystal healing and folklore to be helpful for arthritis, anti-oxidant, arteries, water retention, reproductive system, foot and nail fungal infections. Chalcanthite is a copper sulfate that is very susceptible to humidity and moisture and should be kept in as close to a moisture-free environment as possible to keep its crystal structure from breaking down. It is found naturally in arid areas because of this, although many specimens are grown in the lab.
