Haematite is known as a "stone for the mind". It brings mental organisation and is very grounding and calming. It helps with original thinking, logical thinking, and mathematics. It decreases negativity and can help balance the body/mind/spirit. Physically it has been used to keep the body cool, to decrease blood disorders, nervous problems and insomnia, as well as align the spine and mend broken bones. Haematite is associated with the root (base) chakra. During my first trip to a Rock and Gem Show, I carried a piece of haematite around in each pocket to help ground me from all the strong crystal energy there.
