"Serpentine stone has a strong energy known to stimulate the arousal of the kundalini energies.
If you feel that there may be blockages in any of your chakras, this stone is a useful aid.
It will work at any chakra to clear blocked or stagnant energy.
This green stone may assist with healing problems within the heart and lungs, and it is an excellent stone for cellular regeneration.
It is also a stone to encourage you to make contact with the elemental beings as the members of the Devic realm resonate with its energy. If you wish to aid the healing of the earth, its vibration of earth energy will aid you in this aim." http://www.healing-crystals-for-you.com/serpentine-stone.html
