Barium sulfate, an insoluble in water substance, which was approved under the brand name E-Z-HD for use in double-contrast radiographic examinations of the esophagus, stomach and duodenum to visualize the gastrointestinal (GI) tract in patients 12 years and older. Due to its high atomic number, barium is opaque to x-rays and therefore acts as a positive contrast agent for radiographic studies.

Phenobarbital is a barbiturate derivative used to treat insomnia and anxiety, seizures, hyperbilirubinemia in neonates and cholestasis. Phenobarbital promotes binding to inhibitory gamma-aminobutyric acid subtype receptors, and modulates chloride currents through receptor channels.

Ellagic acid is a dilactone of hexahydroxydiphenic acid, that found in numerous fruits and vegetables. Ellagic acid was first discovered by chemist Henri Braconnot in 1831. Ellagic acid is found in oaks species like the North American white oak (Quercus alba) and European red oak (Quercus robur). The highest levels of ellagic acid are found in walnuts, pecans, cranberries, raspberries, strawberries, and grapes, as well as distilled beverages. It is also found in peach, and other plant foods. Ellagic acid has antiproliferative and antioxidant properties in a number of in vitro and small-animal models. The antiproliferative properties of ellagic acid may be due to its ability to directly inhibit the DNA binding of certain carcinogens, including nitrosamines and polycyclic aromatic hydrocarbons. As with other polyphenol antioxidants, ellagic acid has a chemoprotective effect in cellular models by reducing oxidative stress. Ellagic acid is an investigational drug studied for treatment of Follicular Lymphoma (phase 2 trial), protection from brain injury of intrauterine growth restricted babies (phase 1 and 2 trial), improvement of cardiovascular function in adolescents who are obese (phase 2 trial), and topical treatment of solar lentigines. Ellagic acid has been marketed as a dietary supplement with a range of claimed benefits against cancer, heart disease, and other medical problems. Ellagic acid has been identified by the U.S. Food and Drug Administration as a "fake cancer 'cure' consumers should avoid".

Neoarsphenamine and related compounds are sulfhydryl-binding agents which are tolerated by man. A large experience in the employment of this drug and its toxic manifestations exists as a result of its former use as an antisyphilitic agent. Tertiary syphilis was a common cause for mental health conditions. Also known as Neosalvarsan, it superseded Salvarsan due to its lower toxicity. Both arsenicals still carried significant risk of side-effects and were themselves replaced by penicillin in the 1940s. Neoarsphenamine was also used for the treatment of amebic dysentery.
