Vitamin P - a vital element which the human body can not produce on their own.Valuable properties of this vitamin deserve attention.
history of the discovery of Vitamin P Vitamin P
was described in 1936.Pathfinder was the biochemist A. Szent-Györgyi.He singled out the substance from the peel of the lemon and found that it helps to reduce the fragility and permeability of capillaries.The name vitamin received the first letter of the word «permeability», which means "permeability".The tests were conducted at the beginning of vitamin in guinea pigs infected with the scurvy, and later they passed with participation of people with hemorrhagic diathesis.
Vitamin P brings together a group of biologically active substances called "flavonoids".This group includes about a hundred substances among which are the esculin, hesperidin, catechin, anthocyanin, rutin.Scientists have found that vitamin E may partly cover the deficit of ascorbic acid (vitamin C).Accordingly, it is
this vitamin is best known as a routine, although this is not entirely true (rutin - just one of flavonoids).It explained this "injustice" that are used in medical practice, namely rutin and quercetin.
sources of vitamin P
Flavonoids belonging to the P-vitamin, found in many plants.The best sources are:
• Fruits citrus
• Green walnuts
• Red rowan
• Green tea
• Different types of cabbage
In the pharmaceutical and food industries as a source of used daurskuju or Siberian larch.
benefits of vitamin P
P-vitamins with vitamin C are involved in redox processes.They inhibit the action of the enzyme hyaluronidase that breaks down mucopolysaccharides.Due to this in the body increases the amount of hyaluronic acid, thereby increasing flexibility and reducing capillary permeability.This group of substances has an effect on blood clotting, increases the elasticity of red blood cells.P-vitamins are classified as antioxidants.They protect epinephrine from oxidation and ascorbic acid.
quercetin and rutin (vitamin P medicines) are used for vitamin deficiency and hypovitaminosis P, as well as a number of diseases, which are characterized by violation of vascular permeability (in particular, in retinal hemorrhage, hemorrhagic diathesis, kapillyartoksikozah).The drugs used in the treatment of problems such as radiation sickness, bacterial endocarditis, rheumatism, glomerulonephritis, hypertension, arachnoiditis, allergic diseases, measles, typhus, scarlet fever, trombotsenicheskaya purpura.Vitamin P improves the capillaries in their lesions in patients receiving anticoagulant such as neodikumarin, etc. fenilin. Vitamin P is most effective in combination with ascorbic acid (vitamin C).
Deficiency of vitamin P
At deficiency of P-vitamins in the diet symptoms such as increased capillary permeability.Against this background, bleeding may occur in the mucous membranes, skin, subcutaneous tissue (bruising incentive becomes even minor physical impact - injury, compression and so on.).Hemorrhage caused by vitamin deficiency, usually wear point character (called petechiae).Sometimes they may affect the retina.
Other symptoms of deficiency of P-vitamins are:
• Pain in the legs when moving
• Pain in shoulders
• Spontaneous bleeding
• a bluish tinge to the skin
• The appearance of acne
• Hair loss
• Bleeding gums
Apart from ascorbic acid, vitamin E in the body performs important functions.However, self-prescribe vitamin supplements can not imagine - routine before taking consult your doctor.
