The oil obtained from the seeds of the castor oil plant Ricinus communis is one of the oldest drugs known to man. Castor oil is known primarily as an effective laxative; however, it was also used in ancient times with pregnant women to induce labor. Aside from getting rid of acne, castor oil also helps detoxify the skin. It helps break up the oils that clog glands and pores on the face. Only now, have scientists at the Max Planck Institute for Heart and Lung Research succeeded in unravelling the mysteries of the action mechanism. Ricinoleic acid released from the oil in the intestine, is responsible for the analgesic and anti-inflammatory effects. It was discovered, that G protein-coupled receptors, a large group of receptors in the body involved primarily in transmitting signals in cells. Hundreds of receptors were systematically turned off, and then the reaction of the cells to ricinoleic acid was tested. Ultimately, was succeeded identified the key receptor with the name EP3. There was concluded that after being released from the castor oil, the ricinoleic acid is first of all absorbed by the body via the intestinal mucosa; the EP3 receptor then becomes active on the muscle cells of the intestine and uterus, which in turn stimulates intestinal activity.

Oleanolic acid or oleanic acid is a naturally occurring pentacyclic triterpenoid. It is widely distributed in food and plants where it exists as a free acid or as an aglycone of triterpenoid saponins. Oleanolic acid protects the liver from acute chemically induced liver injury, fibrosis and cirrhosis caused by chronic liver diseases. Its possess cytotoxic activity against tumor cell lines

Sodium dehydroacetate, a water-soluble antiseptic, is a food and feed additive with antimicrobial effects. Recently published studies have shown that sodium dehydroacetate in patients with leg ulcers could cause allergic contact dermatitis.

Sodium chlorite (NaClO2), a sodium salt of chlorite ion, is used as a disinfectant in water treatment and as a component in therapeutic rinses and gels. NaClO2 is an active ingredient of veterinary solution AZTEC GOLD, which is used to reduce the spread of organisms, which may cause mastitis in cows. NaClO2 can increase production of reactive oxygen species, which cause the oxidative stress in human erythrocytes, and as a result, the res cell senescence.

Alpha-linolenic acid (ALA), an 18-carbon omega-3 essential fatty acid, is the precursor of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). ALA cannot be synthesized by humans and therefore must be entirely acquired from exogenous sources. Evidence for the essentiality of ALA was first provided by a study showing that ALA supplementation reversed the abnormal neurologic signs observed in a 6-year-old girl who suffered from sensory loss and visual complications. Most of the ALA is catabolized via beta-oxidation for energy generation, and a small proportion of it undergoes conversion to produce another two potent members of omega-3 PUFA family: EPA and DHA. Delta 6 desaturase (D6D) enzyme is responsible the conversion of ALA to DHA. Although not conclusive, it was suggested, that the benefits associated with ALA seem to stem mainly from EPA and DHA, and as major consequence of ALA deficiency it appears that EPA and DHA are not adequately produced.

Triphosphoric acid (also tripolyphosphoric acid), a condensed form of phosphoric acid. Sodium tripolyphosphate (STPP) is used as a preservative for poultry, meat, and seafood; it’s added to processed cheeses as an emulsifier and is used in food industry as an E number E451.

Maleic acid monosodium salt. Used in water soluble polymers preparation.

Diammonium sulfite monohydrate (Ammonium sulfite monohydrate) has a wide use of applications, such as hair straightening or waving agents, as an ingredient in carmel food coloring, as well as an reducing agent in photography. Other applications include lubricants for cold metal working and blast furnace linings. It is considered safe as used in cosmetic formulations.

Pipemidic Acid is a quinolone antibacterial agent. It’s used in the treatment of urinary tract infections, recidive cystitis, prolongation of the therapy of pyelonephritis (prolonged therapy at patients with tendency to recidives. It belongs to DNA Gyrase inhibitor pharmacological group on the basis of mechanism of action and also classified in Antibacterial pharmacological group. Pipemidic acid is contraindicated at conditions of proved hypersensitivity, severe renal and hepatic insufficiency, cirrhosis of the liver, porphyria, diseases of the central nervous system (epilepsy and neurological conditions with low level for convulsions). Pipemidic acid is contraindicated at children and adolescents at growing phase.

Arsanilic acid, also known as aminophenyl arsenic acid or aminophenyl arsonic acid, is an organoarsenic compound first reported in 1863 by Antoine Béchamp. Arsanilic acid is a crystalline powder introduced medically in the late 19th century as Atoxyl, its sodium salt was used by injection in the early 20th century as the first organic arsenical drug, but it was soon found prohibitively toxic for human use. Arsanilic acid saw long use as a veterinary feed additive promoting growth and to prevent or treat dysentery in poultry and swine. In 2013, its approval by US government as an animal drug was voluntarily withdrawn by its sponsors. Still sometimes used in laboratories, Arsanilic acid's legacy is principally through its influence on Paul Ehrlich in launching the chemotherapeutic approach to treating infectious diseases of humans.
