According to O’Brien, not only did the vaccae microbial bacteria improve their immune system, but patients also demonstrated a sizeable boost in their happiness, vitality and pain relief.

According to a study conducted by neuroscientists Dorothy Matthews and Susan Jenks, published in the Behavioural Processes Journal, “eating, touching and breathing a soil organism may be tied to the development of our immune system and nervous system.” Continue reading
