This balancing and harmonizing bath bomb is my absolute favorite of them all! I decided to leave it a pure white because it is so purely therapeutic. The absolute best bath bomb when you have a headache. Bergamot essential oil is said to stimulate the secretion of hormones which decrease sensitivity of some nerves to pain. It is also uplifting and said to lower levels of depression. Made with therapeutic grade Bergamot essential oil as well as sweet almond oil to soften skin.
