From the very first moments of our birth we are surrounded by microorganisms: spores of mould, bacteria, viruses...

We know that many kinds of them are dangerous, even mortal for the living creatures.

Why are they in the most cases absolutely harmless for us?

Microbes are ancient inhabitants of the planet. Due to the evolution, people, as a biological type of creaures, occcured on the earth later, and they learned to co-exsist with these tiny organisms in symbiosis.

That is why both human life and health is impossible without microorganisms.

Human micro flora is the whole world, a special ecosystem, has been exsisting according to its rules and laws. It includes hundreds types of bacteria with total quantity of about billions.

«Bad» microbes are equal representatives of this galaxy.

Until their number is balanced by «good» ones, they are absolutely harmless for an organism.

Such a balanced micro flora due to the quantitative and typical content is called normo flora.

Various bacteria constantly living inside and outside of the human body are our permanent satellites. For us they produce digestive ferments, disactivate toxins, synthesize vital substansises (vitamins, aminoacids), protect against alien microbes, which include pathogenic ones.

During our life normo flora is not the same (unchangeable), it undergoes fluctuations caused by changes connected with emigration to another climate zone, habitual food products, nervous and stress overloadings.

Otherwise, after short-term fluctuations, flora of a healthy person always reverts to its normal state.

Alien bacteria

In the air indoors there are various microorganisms, including pathogenic microbes. And phytoncides resist them successfully. Qualitative and quantitative content of micro flora is a sanitary index of air pollution degree. Bacterial air pollution is determined by a general microbe number (quantity of microbial cells per one cubic meter of air).
Staphylococci are the most prevailing bacteria. These microbes can be found nearly everywhere: in the air, in the soil, in the water, in the human body etc. Skin and mucous membranes is a natural habitate for them. It is staphylococci that cause different pyogenesis (inflammations). If the immune system is weak any injure of the skin or mucous can provoke staphylococcus infection.
Another «popular» microorganisms are streptococci. Though they are seldom discovered in the environment and in the human body, no human organ is protected against affection of them. Catching diseases caused by streptococci are proceeded seriously, especially if the immune system is decreased.
In the human intestinal tract there is collibacillus, which is considered to be opportunistic pathogen, as it doesn't have a negative impact on the organism. But if collibacillus is discovered in the air of the living space, it gets dangerous, and such plants as cherry laurel, pittosporum, laurel can help get rid of it.
Klebsiellas occupies a special place among pathogenic bacteria which can cause pneumonia, purulent and fibrinous pleurisy, pericarditis, meningitis, genyantritis and other diseases. But such plants as monarda, mint, lavender, hyssop and clary sage can protect against such a bacterium. Everybody who had ever stayed in hospital is aware of nosocomial infection. It is blue pus bacillus which causes infection disease. Getting inside of the body of the sick people it provokes heavy complications. But if there were akalifa, aucuba, boxtree, lauristinus, cypress in the halls and in the wards of hospitals sucn an infection could be avoided. Fungi diseases also occupy a special place. Nowadays about 400 fungi are known which can cause various catching human diseases. Yeast-like fungi of candida type provokes such an unpleasant illness as candidosis. Despite the fact that all candidosises are not treated well, this fungi is rather sensitive to phytoncides of lavender, mint, rosemary, myrtle and other odoriferous plants. In this connection we recommend to grow these outdoor plants on the window sills.

Howerever, healing properties of phytoncides are not limited only by these actions. They impact either on pathogenic micro flora or people.
