Seawater has been used for therapeutic and preventive purposes since ancient Egypt, Hellas, and other countries of the ancient world. However, healing properties of sea water were briefly forgotten in the Middle Ages. With the rise of science, a considerable variety of medicinal properties, which seawater has on the human body, was discovered and observed.
The pharmacological properties of seawater result largely from the presence of ions in it, which carry positive and negative charges of natural electricity, diverse microelements, heavy metals, biologically active substances and others. Seawater is bacteriostatic and is extensively applied for therapeutic purposes and mineral baths . However, seawater must be excluded from drinking, even in small doses, as it is not a pure substance in its biological composition and can be harmful to the body. The advantages of seawater are abundant, it:

- encourages deep sleep;
- prevents hair loss;
- reduces the dark circles and sagging bags under the eyes;
- has a rejuvenating effect;

All these health benefits are due to the chemical composition of seawater. It contains:

Seawater can be dangerous for patients suffering from infectious illnesses, allergies to iodine, as well as some skin and fungal diseases in particular.
