The majority of articles I published were focused on health. I’m very interested in using natural remedies as they enhance the body's ability to heal itself and have no harmful side effects. I became interested in natural remedies when I met a Gerson therapist, who told me that in Gerson therapy they use “ live food” (organic vegetable, fruits, etc) to cure their patients. For the body to fight different illnesses, our immune system should be strong. In Gerson therapy they promote the supplementation of healthy and nutritious “ live food” for the body to fight disease, repair and regain its strength. I hope you will enjoy and learn from reading my articles. Have a good day and lets all be healthy :)
