Chestnut is a great and sturdy wood with an excellent sense of justice and diplomacy. It is a very interested wood, seeking knowledge through experience and high intellectual thought (which lends to its other properties). Very grounding, it can help with clarity of the mind and the flow of energy. Also good for soothing love and easing disputes or troubles in relationships.
