And till a moment,a how detailed stopping on a warm using, a need to remember about a two base physiologic peculiarities

  as about an inflammation process, fever.And inflammation mobilizes are  natural forces of organism against external aggression.And inflammation process characterizing with hyperaemia, and last maybe to enlarge by warm. And of course a warm is hardening acute inflammation, but on a process he causes an other result,as stops or prevents venous stagnation in capillaries, restoring blood circulation and removing metabolites, microbes and destroying cells in a big current of a common circulation,where is realizing general cleaning against toxic metabolites and theirs splitting in macromolecules, theirs mixing and removing. And in inflammation parts after restoring a blood circulation, a mechanical factor stops an own effect as squeezing parenchymatous cells as a most high widening by venous vessels. And will be restoring a supply of an oxygen, and other nourishing substances and create will be   all conditions for a tissue regeneration.About physiological peculiarities a fever has been talked in a chapter about hypertonic baths.And professor Lampert, 1952 has been shared, that artificial hyperaemia improves  feeding and tissue grow, and he is holding position by Bier ,1931,which written in an own fundamental labour Hyperaemia as a cure remedy, without a deep knowledge about capillaries are never understand are about inflammation processes, fever, and other physiologic phenomenon. 

And if a know physiology and capillaries pathology and intracellular and extracellular liquids, is staying understand, why a warm using in acute and chronic diseases  with aggregation are remedies, stimulating activity for capillaries,as a so effecting good in acute rheumatic and acute phlegmon  arthritis, tuberculosis etc.
