Arsenic is the chemical element of atomic number 33 (symbol As), a brittle steel-gray metalloid. It occurs naturally and is widely distributed through the earth's crust. It is highly toxic in its natural form and is present in groundwater in many locations.[1]

Interactions with chronic fatigue syndrome[edit | edit source]

Researcher Walter Tarello has examined veterinary use of arsenic compounds thiacetarsamide sodium to treat animal illnesses that appear to resemble chronic fatigue syndrome (CFS).[2][3][4][5] Tarello and his wife, who works with him, are also both diagnosed with CFS and treated themselves with arsenic compound potassium arsenite, reporting remission.[6]

chronic fatigue syndrome (CFS) - A controversial term, invented by the U.S. Centers for Disease Control, that generally refers to a collection of symptoms as “fatigue”. There have been multiple attempts to come up with a set of diagnostic criteria to define this term, but few of those diagnostic criteria are currently in use. Previous attempts to define this term include the Fukuda criteria and the Oxford criteria. Some view the term as a useful diagnostic category for people with long-term fatigue of unexplained origin. Others view the term as a derogatory term borne out of animus towards patients. Some view the term as a synonym of myalgic encephalomyelitis, while others view myalgic encephalomyelitis as a distinct disease.

ME/CFS - An acronym that combines myalgic encephalomyelitis with chronic fatigue syndrome. Sometimes they are combined because people have trouble distinguishing one from the other. Sometimes they are combined because people see them as synonyms of each other.

Chronic Fatigue and Immune Dysfunction Syndrome (CFIDS) - Chronic Fatigue and Immune Dysfunction Syndrome is another term for Chronic Fatigue Syndrome, but one which emphasizes the immunological aspects of the disease. Popular in the 1990's, this term has apparently fallen into disuse.

World Health Organization (WHO) - "A specialized agency of the United Nations that is concerned with public health. It was established on 7 April 1948, and is headquartered in Geneva, Switzerland. The WHO is a member of the United Nations Development Group. Its predecessor, the Health Organization, was an agency of the League of Nations." The International Statistical Classification of Diseases and Related Health Problems (ICD) is maintained by WHO.
