Mercury(I) iodide is a chemical compound that has been used as a drug in the 19th century, sometimes under the contemporary name of 'protiodide of mercury'. Mercury(I) iodide was used to treat a wide range of conditions; everything from acne to kidney disease and in particular was the treatment of choice for syphilis. It was available over the counter at any drugstore in the world, the most common form being a concoction of protiodide, licorice, glycerin, and marshmallow. Taken orally, and in low doses, protiodide causes excessive salivation, fetid breath, spongy and bleeding gums, and sore teeth. Excessive use or an overdose causes physical weakness, loss of teeth, hemolysing (destruction of the red blood cells) of the blood and necrosis of the bones and tissues of the body. Early signs of an overdose or excessive use are muscular tremors, chorea, and locomotor ataxia. Violent bloody vomiting and voiding also occur.

Diammonium carbonate is a salt with the chemical formula (NH4)2CO3. Since it readily degrades to gaseous ammonia and carbon dioxide upon heating, it is used as a leavening agent and also as smelling salt. Ammonium carbonate may be used as a leavening agent in traditional recipes, particularly those from northern Europe and Scandinavia (e.g. Speculoos, Tunnbröd or Lebkuchen). It also serves as an acidity regulator and has the E number E503. Ammonium carbonate is the main component of smelling salts, although the commercial scale of their production is small. Buckley's cough syrup from Canada today uses ammonium carbonate as an active ingredient intended to help relieve symptoms of bronchitis. Ammonium carbonate is also used as an emetic.

Potash (Dihydroxyaluminum Sodium Carbonate), a component of Kompensan-S Forte in Germany, is a basic inorganic salt that acts by neutralizing hydrochloric acid in gastric secretions. Kompensan-S Forte is slowly solubilized in the stomach and reacts with hydrochloric acid to form aluminum chloride and water. It also inhibits the action of pepsin by increasing the pH and via adsorption. Cytoprotective effects may occur through increases in bicarbonate ion (HCO3-) and prostaglandins.

Tetraglycine hydroperiodide is an iodine-containing chemical, used for water purification. Tetraglycine hydroperiodide is marketed in tablets; each tablet effectively disinfects 1 liter of clear water or 0.5 liter of tainted water by releasing approximately 8 mg free iodine. It requires approximately 30 minutes to inactivate target microorganisms and make water bacteriologically suitable for drinking. To remove iodine taste, a vitamin C pill is added to the kit.

Ferric Ammonium EDTA Solution is normally used as a photographic chemical for a bleaching agent in the process of colour washing. It is also used as a complexing, and oxidizing agent & as a fertilizer and catalyst. EDTA acid are colourless, water-soluble solid that are widely used to dissolve scale. The usefulness of these ammonium salts arise because of its role as a chelating agent, i.e. its ability to "sequester" metal ions such as Ca2+ and Fe3+.

Magnesium diamide is used as a chemical intermediate. Magnesium diamide is spontaneously combustible. It is toxic by inhalation. Skin or eye contact may cause severe burns.

Olaflur (amine fluoride 297, trade name elmex gel) is a fluoride-containing substance that is an ingredient of toothpastes and solutions for the prevention of dental caries. Especially in combination with dectaflur, it is also used in the form of gels for the treatment of early stages of caries, sensitive teeth, and by dentists for the refluoridation of damaged tooth enamel. Olaflur is a salt consisting of an alkyl ammonium cation and fluoride as the counterion. With a long lipophilic hydrocarbon chain, the cation has surfactant properties. It forms a film layer on the surface of teeth, which facilitates incorporation of fluoride into the enamel. The top layers of the enamel's primary mineral, hydroxylapatite, are converted into the more robust fluorapatite. The fluoridation reaches only a depth of a few nanometres, which has raised doubts whether the mechanism really relies on the formation of fluorapatite.
