Blue Chalcedony is used by metaphysical healers for healing anything related to the throat and respiratory tract. It is believed to be especially good for vocal strain, due to singing/shouting as well as damage caused by smoking. It is believed to reduce extreme weather sensitivity, as well as pressure in the eyes and ears. Blue Chalcedony is also said to encourage lactation in new mothers and reduce weight retention, making it an excellent postpartum crystal.
