I believe that we can heal ourselves naturally when we focus on our mind, body, and soul and give it what it needs.
For the body that means good, healthy, whole, and unprocessed foods, and addressing any vitamin and mineral deficiencies. It also includes using organic and natural products on your body, and eliminating exposures to toxic chemicals and pesticides.
For the mind and soul this means healing from within by addressing toxic relationships, dealing with past traumas, positive affirmations, and more.
There's much more to this but that's the very basics.
