It is most often used to describe the assumption that what the person calls "chemicals", usually meaning man-made products or artificially concentrated but naturally occurring chemicals, are bad and harmful, while what the person calls "natural" substances (i.e., chemicals that occur naturally or that are obtained using traditional techniques) are good and healthy.[1] General chemophobia derives from a public lack of trust, inadequate understanding of chemistry and science,[2] and is a form of technophobia and fear of the unknown.
