Howlite is a gem which regulates the emotions to assist in walking the "middle path". It promotes peace within connecting to the untouched, innocent aspect. It can be a useful tool for those who are overrun by their emotions and let that dictate their actions (such as those who have a temper manifesting as road rage or anger resulting in hitting, etc.).
Howlite actually targets frustration and stress to relieve the "build-up" of these energies which tend then to create an apparent uncontrolled response. It is then a great gem to use prior to high-stress situations to assist in bringing forth one's peaceful center.
Howlite can also provide comfort in dealing with grief. A close death tends to inspire helplessness and overwhelm because of the great changes it instigates. This gem restores a balanced perspective and gives strength to move forward.
Howlite, on a physical level, has a regenerative quality that assists the skin and tissues. It also benefits the bones through its regulation of calcium.
