Alternative medicineUnscientific healthcare practicesAlternative medicine comprises practices that aim to achieve the healing effects of medicine, but that lack biological plausibility, testability, repeatability, or supporting evidence of effectiveness. Such practices are not part of mainstream evidence-based medicine.
ChelationChelation () is a type of bonding and sequestration of metal atoms. It involves two or more separate dative covalent bonds between a ligand and a single metal atom, thereby forming a ring structure. The ligand is called a chelant, chelator, chelating agent, or sequestering agent. It is usually an organic compound, but this is not a requirement.
Cardiovascular diseaseDisease involving heart or blood vesselsMedical conditionCardiovascular disease (CVD) is any disease involving the heart or blood vessels. CVDs include coronary artery diseases (e.g. angina, heart attack), heart failure, hypertensive heart disease, valvular heart disease (e.g. rheumatic heart disease), cardiomyopathy, arrhythmia, congenital heart disease, carditis, aortic aneurysms, peripheral artery disease, thromboembolic disease, and venous thrombosis.

ArsenicArsenic is a chemical element; it has the symbol As and atomic number 33. It is a metalloid and one of the pnictogens, and therefore shares many properties with its group 15 neighbors phosphorus and antimony. Arsenic is notoriously toxic. It occurs naturally in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. It has various allotropes, but only the grey form, which has a metallic appearance, is important to industry.
Ethylenediaminetetraacetic acidEthylenediaminetetraacetic acid (EDTA), also called EDTA acid, is an aminopolycarboxylic acid with the formula [CH2N(CH2CO2H)2]2. This white, slightly water-soluble solid is widely used to bind to iron (Fe2+/Fe3+) and calcium ions (Ca2+), forming water-soluble complexes even at neutral pH. It is thus used to dissolve Fe- and Ca-containing scale as well as to deliver iron ions under conditions where its oxides are insoluble.
Heavy metalsTerm used for certain metallic elementsCrystals of osmium, a heavy metal nearly twice as dense as leadHeavy metals is a controversial and ambiguous term for metallic elements with relatively high densities, atomic weights, or atomic numbers. The criteria used, and whether metalloids are included, vary depending on the author and context, and arguably, the term "heavy metal" should be avoided.
AutismAutism, also known as autism spectrum disorder (ASD), is a condition characterized by impairment in social communication and interaction, as well as a need or strong preference for predictability and routine, sensory processing differences, focused interests, or repetitive behaviors. Features of autism are present from early childhood and the condition typically persists throughout life.
ToxicologyToxicology is a scientific discipline, overlapping with biology, chemistry, pharmacology, and medicine, that involves the study of the adverse effects of chemical substances on living organisms and the practice of diagnosing and treating exposures to toxins and toxicants. The relationship between dose and its effects on the exposed organism is of high significance in toxicology.
CancerGroup of diseases involving cell growthMedical conditionCancer is a group of diseases involving uncontrolled cell growth typically resulting in tumors with the potential to invade or spread to other parts of the body. These malignant tumors contrast with benign tumors, which do not spread. Over 100 types of cancers affect humans. About 33% of deaths from cancer are caused by tobacco and alcohol, obesity, lack of fruit and vegetables in the diet and lack of exercise.

QuackeryQuackery, often synonymous with health fraud, is the promotion of fraudulent or ignorantmedical practices. A quack is a "fraudulent or ignorant pretender to medical skill" or "a person who pretends, professionally or publicly, to have skill, knowledge, qualification or credentials they do not possess; a charlatan or snake oil salesman".*As an Amazon Associate I earn from qualifying purchases.
