Boji stones are "harvested" as soil erodes exposing them as "stones." They are found on stems. They are considered living and found under a naturally-pyramid shaped mountain in Kansas. Read about them on the Internet.
Use them in place of acupuncture needles.
Keep a pair in the freezer for the immediate application upon a burn. These come with a certificate of authenticity. The male stone has a rough crystalline surface and the female stone is smooth. Hold them as you would a pair of magnets. If you do not feel a pulling sensation, turn one of the stones around. Each pair comes with a pamphlet of information about how to use them as channeled and written by Karen and Jerry Gillespie.
