Anhydrous dibasic calcium phosphate is a calcium salt of phosphoric acid. It is used as a diluent in pharmaceutical industry, in some toothpastes as a polishing agent. Calcium phosphate is generally recognized as safe by FDA. Dibasic calcium phosphate is ised as a supplement to treat conditions associated with calcium deficit, such as bone loss (osteoporosis), weak bones (osteomalacia/rickets), decreased activity of the parathyroid gland (hypoparathyroidism), and a certain muscle disease (latent tetany)

Ferric chloride is a compound used as a food additive, a haemostatic or treatment for hypochromic anaemia. Ferric chloride induced vascular injury is a widely used model of occlusive thrombosis that reports platelet activation and aggregation in the context of an aseptic closed vascular system. Iron i.v. ferric chloride (960 mg) has being shown to be effective in correcting anaemia in HD patients with iron deficiency.

Struvite, a crystalline substance first identified in the 18th century, is composed of magnesium ammonium phosphate. Struvite urinary stones are also known as ‘infection stones’, and account for 15%-20% of all urinary stones. Bacterial urease, usually from a Proteus species, is responsible for the chemical changes in urine which result in struvite formation.

Strychnine is an indole alkaloid obtained from the seeds of the Indian tree Strychnos nux-vomica. It gets its scientific name “strychnos” from Carl Linnaeus, who classified it back in 1753, but it was known to the population of India way before then. Nux vomica originates in India. Strychnine-containing baits are currently labelled for below-ground use and are intended for the control of pocket gophers. Their use as indoor pesticides has been eliminated since 1989. In the past, strychnine has been used as a pesticide to control rats, moles, gophers, and coyotes. Strychnine is highly toxic to most domestic animals. Strychnine is a competitive antagonist at glycine receptors and thus a convulsant. It has been used as an analeptic, in the treatment of nonketotic hyperglycinemia and sleep apnea.
