How does Sterimar Manganese Nasal Spray work?

The nasal mucosa is made of 3 layers of cells.

The respiratory tract’s epithelial cells have small extensions, similar to little hairs, called cilia, and it is with their help that the excessive mucus gets cleaned. Sometimes however, when we catch a cold or when we are exposed to germs and allergens, the body needs a little help cleaning the excessive mucus.

Sterimar’s unique microdiffusion technique consists of applying a very delicate sea-water based spray on the nasal mucosa. The droplets are extremely fine thus staying longer in contact with the mucosa. This prolonged contact improves the penetration of trace elements and helps remove excessive mucus and allergens which endanger the health of your nose.

This nasal solution works by drawing the liquid from the mucosa back into the nasal cavity where it can be easily cleansed by simply blowing your nose.

Many patients believe that any nasal congestion is caused by a runny or a stuffy nose. In fact, the congestion is a result of the inflammation caused by irritants or alergens, which makes the nasal tissues swollen, reducing the size of the nostrils. Therefore, breathing through your nose becomes very tricky. Usually, when we catch a cold or when we have flu symptoms, the nasal congestions is also accompanied by a runny nose which makes breathing through the nose virtually impossible.

Sterimar Hypertonic Nasal Spray for Adults is a hypertonic solution. The hypertonic solution has a slightly higher salt concentration than is normally found in the human body. This aspect favors osmosis,the natural process through which one or more substances move through a semi-permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides.  Osmosis helps remove the excess fluid filled with germs in the nasal mucosa, aiming to provide natural relief in the case of nasal congestion and prompt natural breathing through the nose. In addition, this product is enriched with Manganese and this trace element enhances the solution’s properties, helping your body fight against irritants and infections. The whole process is quick, gentle and painless.

Manganese is a very common compound and can be found anywhere on Earth. Manganese is one of the three essential toxic trace elements. Putting “essential” and “toxic” next to ano another may sound strange but this means that on the one hand, Manganese is necessary to the survival of the human body and on the other hand it means that in too high concentrations, it can end up posing a health risk.

Absorbing Manganese is made possible by eating certain foods rich in this trace elment, such as spinach, tea and some aromatic herbs. The foods with the highest Manganese concentration are cereal, rice, eggs, nuts, olive oil and oysters. After its absorption in the body, the Manganese is transported in the blood to the liver, kidneys, pancreas and endocrine glands.

The Manganese deficiency can lead to glucose intolerance, dermatological problems, neurological symptoms, etc. ATTENTION! Excessive Manganese in the body is just as dangerous. Ask your doctor before taking any food supplement containing Manganese. The daily dosage depends on each organism – age, weight, medical history and other particularities. Manganese is essential to the survival of the human body – too little or too much of it can lead to various types of imbalance.

About the packaging

Each dose of Sterimar spray is aseptic. The non-return valve prohibits any air contamination into the package so the solution stays perfectly aseptic after each use. Thus, Sterimar can be used safely again until the product runs out completely.

The microdiffusion effect is produced by the nozzle which is specially designed for Sterimar. The device is fit for all nostril sizes and blocks itself after use: it can be safely used on the tiny nostrils of babies as well as on the nostrils of an adult. Its diameter is able to adapt to all nostril sizes and prevents any risks when inserting the nozzle into the nostrils of a baby.

NOTA BENE: The nozzle cannot cause injury and cannot be inserted too far into the nostril.
