Green obsidian is used a lot during reiki to help balance the heart chakra specifically but also the throat chakra too. This stone removes hooks and ties caused from other people. It is great for treating the gallbladder and the heart. Not only is it great for relaxation and stress but it helps ease insomnia, protects you from nightmares, promotes the ability to flow with change, it promotes confidence, and helps you with the idea that everything is alright.
This stone is great for people who want personal counselling but don’t seem to be getting anywhere as it will help them really tackle their problems and help them become more self reliant. It is also great at keeping people away that will only drag you down with their own personal crises. Keep this crystal on you if you work with people (especially troubled ones) to keep your energies light and positive.
Lastly, if you worship Gaia, like myself, and you want to have some sort of tribute to her on your altar or make a little gaia jar this is a great crystal to put in it!
