Pharmaceutical drugs, sun screen etc. etc. now there is your snake oil... people are ill\sick due to nutritional and\or elimination deficiencies, or worse a toxic overload caused by ubiquitous environmental toxins that is stored in their body fat and tissues.
These things cannot be corrected by a pill or topical ointment. We do not have Paxil (pick your poison) deficiencies. With today’s very poor quality of food, primarily due to environmental toxic overload, and acidic soils, illnesses\diseases are getting harder to correct even with unprocessed raw organic and home grown produce.
