Animal Magnetism; A Mesmerizing Yet Controversial Past of Healing Sciences
International Journal of Endorsing Health Science Research, 2020 Background: Animal magnetism gained popularity in the 18th century specifically among Europeans and the people from the United States. The Mesmer’s theory on animal magnetism emphasized the presence of invisible natural force in all living organisms i.e.
