Withчины

Withчины возникновения экземы достоверно неизвестны. Believed
that most often the disease develops as a result of the influence
following factors:

Internal (endogenous) factors:

  • diseases of internal organs, including digestive organs

    facilitiesми, а также прочими химическими веществами
  • infectious agents – streptococci, staphylococci, fungi

excreted in the feces, and what is absorbed inside, is neutralized in
liver and excreted by the lungs. In case of abnormal liver function,
kidney or intestinal toxic metabolic products greater
part begin to be excreted through the skin. If this goes on for a long time,
