This means it’s excellent to use with jewellery- which is great because healing is best when close to the skin.
Yang and Yin are words to describe opposite complementary forces of nature. Yang means warm, contracted, and more centripetal in the heart. Yin means colder, more expanded, and more centrifugal.
