It is used as a zinc supplement in animal feed, to prepare fertilizers and agricultural sprays. Zinc sulfate heptahydrate, ZnSO 4 · 7H 2 O, is used in the manufacture of lithopon (zinc white), and rayon (artificial silk), as a wood preservative, as electrolytes for zinc plating (zinc plated), as a mordant of coloration, to preserve skins and leather, and in Medicine, as an astringent and emetic. An aqueous zinc sulfate solution is effective in removing moss from pavements and floors.

Uses of zinc sulfate have been reported to mask drug testing and analysis because it acts as a chelator for molecules, removing them from the urine. As a micronutrient in fruit, vegetable and annual crops. As a chemical reagent in mining, flotation agent in minerals. Bleaching paper with the hypochlorite . Rubber clarifier.

In the health

To correct the following clinical alterations when they coexist with low zinc serum values: Delayed growth. Hypogonadism in males. Dermal changes. Tissue repair processes such as wound healing, pressure ulcers and lower limb ulcers. Abnormal immune function: acrodermatitis enteropathica . Decreased appetite. Nythalopia (night blindness). Hypogeusia (decreased sense of taste). Disorders of the sense of smell.


Zinc reduces the cardiovascular risk factor in the patient with type 2 diabetes

Diabetes is a worldwide public health problem of great concern; The same happens with increases in the demand for health services by patients with this disease, plus the expenses derived from their absence from work. In contrast to someone with type 1 diabetes, the body of a person with type 2 diabetes still produces insulin, although it does not respond to it normally.

Treatment with zinc sulfate could mean a reduction of the cardiovascular risk factor for these patients, according to a report prepared by the Faculty of Medical Sciences of Mexico.

This statement arises from the result of administering zinc sulfate for 12 weeks to patients with these characteristics in a hospital unit. Patients undergoing treatment experienced an improvement in metabolic status, recovery of cardioprotective lipoprotein levels and micronutrients; also, a decrease in triglyceride and total cholesterol concentrations was observed.
