Preparations from tea
What preparations does the pharmaceutical industry make from tea? These are well-known drugs that are familiar to many of you: caffeine, theobromine, neofillin and combination preparations containing caffeine.
To emphasize the strength of caffeine, I will quote excerpts from the reference book on clinical pharmacology on the pharmacodynamics of the drug: "Caffeine is a stimulant of the central nervous system. Strengthens and regulates the processes of excitation in the cerebral cortex. Increases mental efficiency, facilitates perception, the emergence of associations, speeds up the reaction time. Increases motor activity, reduces fatigue and drowsiness. Excites the respiratory and vasomotor centers of the medulla oblongata. "
Increase in blood pressure, deepening and rapidity of breathing are usually manifested in the background of a decrease in the functions of the centers of the medulla oblongata in collaptoid and shock states, poisoning with substances depressing the nervous system, and are not expressed under normal conditions.
In medicine, tea preparations are widely used in many diseases. Caffeine is indicated in conditions of general weakness accompanied by respiratory depression, weakening of cardiac activity, lowering of arterial pressure, acute infectious diseases, mental and physical exhaustion, poisoning with drugs, especially alcohol, cerebrovascular disorders accompanied by headaches, in which caffeine and its combinations are effectivewith other conventional drugs( phenacetin, antipyrine, amidopyrine).Theobromine is used for angina, atherosclerosis, hypertension and as a diuretic.
A mixture of theophylline and ephedrine is effective in bronchial asthma, angina pectoris, hypertensive crises and congestive events on the basis of cardiovascular insufficiency. Vitamin P lowers blood pressure, reduces permeability and fragility of blood vessels, increases blood coagulability. Preparations of tea are recommended for hemorrhagic diathesis, edema, capillary hemorrhage and trophic ulcers.
