Samuel Thomson

  • Born: February 9, 1769; Alstead, New Hampshire
  • Died: October 4, 1843; Boston, Massachusetts

Overview

Samuel Thomson was an American herbalist who founded the alternative medicine system that came to be called Thomsonian medicine. This system, which involves removing toxins from the body through various purging methods, reached its peak in popularity in the United States in the nineteenth century. It has been suggested that Thomson was the foremost contributor to herbal science in the United States, even though he was not formally trained in medicine.

Thomson was born and raised in rural New Hampshire, during which time he nurtured an interest in the outdoors and various plants and other wildlife. As a child, he reportedly consulted regularly with a local woman who had a reputation as a healer and herbalist. Thomson was discouraged from entering life in academia, and he continued working as a farming attendant until he was seriously injured at the age of nineteen years. He reportedly healed his own wound with comfrey root and turpentine plaster after the wound failed to heal with treatment from a formal physician. He also was said to have used another concoction of herbs to cure his case of measles.

Later in life, Thomson retained herbalists to treat his wife when she became ill after childbirth; she had an ailment that was not healed by the efforts of several traditional doctors. Building on the methods used by the herbalists who successfully treated his wife, Thomson eventually developed his medicine system.

Thomson also discovered a use for the flowering herbal plant Lobelia, which became one of the key ingredients of his system of medicine. He later patented this use and promoted it as a cure for various ailments. However, its use was followed by troubling reports of serious side effects and even deaths. At one point, Thomson was brought to court to defend his herbal remedies after a physician who treated a patient who had used Thomson’s approach made accusations of malpractice.

Thomson also claimed that exposure to cold temperatures causes illness, which could be cured, he believed, by re-establishing the body’s original temperature. This temperature increase was often induced with steam baths, laxatives, vomiting, and spicy foods such as hot peppers.

Although many of Thomson's ideas lack scientific evidence, his influence on the field of herbal medicine was significant. At a time when traditional medicine included dubious practices, such as mercury use and bloodletting, Thomson's focus on affordable herbal and natural options provided many with accessible healthcare alternatives. His emphasis on holistic health and patient empowerment continues to resonate in the twenty-first century, and his work strongly influenced later health movements such as naturopathy.
