Gives Child I have seen many times use saliva especially from animals to deteriorate to disinfect abrasions or wounds ( I refer to animals that lick for “to clean up” dogs, cats and more). Cats even get wet paw to rub it in his face , on the head , not having a language as long as dogs.
An article dedicated to man reminded me of saliva, with its components and its important functions. Hear that there are mothers who “wash” The pacifier of the infants with saliva , putting it in the mouth , He did not upset me but having other means and solutions today that can be at hand even outside the home and above all having notions of hygiene, They do not even upset me those who horrify by reading these human practices. Then, without commenting much , Let's see what the saliva is but being careful to consider other hygiene factors and knowing the difference of what can be physiological but also , without knowing it, pathological.
Of each situation then the risks and benefits of what you do must always be considered.
The term saliva or bava is indicated, in physiology, the liquid that is secreted by the salivary glands located in the oral cavity. The three couples of salivary glands are pure serous secretion parotids, The submandibular and sublinguals with a mixed mainly serous secretion for the first and mucous membrane for the latter.

Human saliva is a fluid composed of:

Water (98%);
Electrolytes of which:
2-21 tube/Lo,
10-36 mmol/l potassio,
1,2-2,8 MMOL/L FOOTBALL,
0,08-0,5 mmol / l magnesio,
5-40 mmol/l ion chloride,
25 mmol/l bicarbonate ion,
1,4-39 mmol/l ion phosphate;
Mucus composed of glycosaminoglycan and glycoproteins;
Antibacterial compounds such as peroxidase and type A peroxidase and immunoglobuline enzyme (IgA);

Enzymes

The main ones are:
α-amilation (EC3.2.1.1), Known as a Pytalina
Lisozima (EC3.2.1.17), with antibacterial function.
Lipase (EC3.1.1.3).
Other enzymes including: acid phosphatase (EC3.1.3.2), lactoperoxidase (EC1.11.7), SUPEROSSIDO DISMUTATION (EC1.15.1.1), aldehyde dehydrogenase (EC1.2.1.3);
Human cells;
Bacteria and in some cases also viruses;
Other substances to a lesser extent Pepsina, testosterone, urogastrone.

Functions

Moisten the food and make it more digestible.
Solvent
Due to the serous component rich in water
Humor
Exercised by the mucous membrane that humets the food bolus in order to avoid lacerations to the passage of this to the bucal and esophageal epithelium.

Antibacterial
The presence of Lisazima, lactoferrine, Io -like and antibodies allow to oppose the life and growth of bacteria that are introduced within the oral cavity. They also protect us from infectious bacteria.
Saliva can therefore act as a natural disinfectant. Generally saliva presents a neutral pH (which oscillates between 6,5 and 7,5 about), which comes to acidify as a result of a lack of oral hygiene, or with the introduction of low pH foods or drinks. The achievement of salivary pH values around 5,5 (slightly acid) It can lead to the solubilization of the main inorganic component of the hard tissues of the tooth, the hydroxyapatitis, predisposing the onset of dental caries or acid erosion., lactoferrine, Io -like and antibodies allow to oppose the life and growth of bacteria that are introduced within the oral cavity.

Digestiva
Thanks to the presence of Piamina, an α-amylasi capable of splitting the α-1,4 glucidal ties containing at least three units of glucose in the structure.

Conclusions
In physiological conditions the use of saliva as a means of “washing” easy to use and in case of need , it shouldn't be horrified. But who can know the state of health of yourself too?
And then, Better to use other tools to wash or disinfect; Avoid direct contact also with your family members; Avoid using the same cutlery too: Viruses and bacteria can be present without having still manifested and then remember that many bacteria nest in many foods or objects that without realizing it we put in the mouth.
