Malic acid is a tart-tasting organic dicarboxylic acid that contributes to the taste of many sour or tart foods such as apples. Sodium Malate is the sodium salt of Malic Acid. Malic Acid and Sodium Malate can be found in a wide range of cosmetics and personal care products. Sodium Malate functions as a skin conditioning agent-humectant. As a food additive, Sodium Malate has the E number E350. Sodium Malate has demonstrated protective effect on cisplatin-induced toxicity in mice. Sodium malate could become a useful agent for the reduction of CDDP-induced toxicity, particularly nephrotoxicity and hepatotoxicity.

Tannic acid (TA) is a naturally occurring plant-derived polyphenol found in several herbaceous and woody plants, wines and a broad selection of teas. TA has strong antioxidant/free radical scavenging, anti-inflammatory, anti-viral/bacterial, and anti-carcinogenic properties. The neuroprotective effects of TA against Alzheimer’s disease (AD) have been shown in several in vitro and in vivo models of AD. Evidence suggests that TA is a natural inhibitor of β-secretase (BACE1) activity and protein expression. BACE1 is the primary enzyme responsible for the production and deposition of Aβ peptide. TA can also inhibit the in vitro aggregation of tau peptide, a core component of intracellular neurofibrillary tangles (NFTs). In addition, combination of tannic acid with eucalyptus Oil and Allantoin (from Comfrey) is known as homeopathic product which is used to temporarily relieve the aches and pains of muscles and joints associated with: arthritis, simple backache, strains, bruises, sprains.

Hydroxocobalamin (also hydroxycobalamin, OHCbl) is a natural form, or vitamer, of vitamin B12. It is a member of the cobalamin family of compounds. Hydroxocobalamin, the active ingredient in Cyanokit, is cobinamide dihydroxide dihydrogen phosphate (ester), mono (inner salt), 3’-ester with 5,6-dimethyl-1-α-D-ribofuranosyl-1H-benzimidazole. The drug substance is the hydroxylated active form of vitamin B12 and is a large molecule in which a trivalent cobalt ion is coordinated in four positions by a tetrapyrol (or corrin) ring. It is a hygroscopic, odorless, dark red, crystalline powder that is freely soluble in water and ethanol, and practically insoluble in acetone and diethyl ether. Cyanokit contains hydroxocobalamin, an antidote indicated for the treatment of known or suspected cyanide poisoning. Cyanide is an extremely toxic poison. In the absence of rapid and adequate treatment, exposure to a high dose of cyanide can result in death within minutes due to the inhibition of cytochrome oxidase resulting in arrest of cellular respiration. Specifically, cyanide binds rapidly with cytochrome a3, a component of the cytochrome c oxidase complex in mitochondria. Inhibition of cytochrome a3 prevents the cell from using oxygen and forces anaerobic metabolism, resulting in lactate production, cellular hypoxia and metabolic acidosis. In massive acute cyanide poisoning, the mechanism of toxicity may involve other enzyme systems as well. Signs and symptoms of acute systemic cyanide poisoning may develop rapidly within minutes, depending on the route and extent of cyanide exposure. The action of Cyanokit is based on its ability to bind cyanide ions. Each hydroxocobalamin molecule can bind one cyanide ion by substituting it for the hydroxo ligand linked to the trivalent cobalt ion, to form cyanocobalamin, which is then excreted in the urine.
