By utilizing a sound nutritional lifestyle ( I always recommend a raw living foods diet with minimally organic produce), rebuilding the gut flora, cleansing the elimination and detoxification organs, and purifying blood your health will soar.
Also do necessary lifestyle changes that will ensure you don't get any toxins reintroduced into your system. Sources include mold, chemicals, and emf.
Reduce stress and re-frame your life so it is empowering and creative in nature. Do emotional healing as well. Have a passionate life purpose.
