It may be stated that people have been drinking tea for a long period of time. It is one of the widely used products of our food. Recently, valuable research work on the properties of tea has been carried out in Moscow and abroad. It has been firmly established that tea contains chemically active substances from which many medical preparations possessing curative properties can be derived. Drugs made from tea catechol improve the functioning of the capillaries whose cell walls have lost their elasticity resulting in hemorrhages. Observations have proved that tea catechols are to restore their normal condition in the course of 2 – 3 weeks.
It should be noted that in treating poliomyelitis and acute rheumatism patients have to take tea catechols. Respiratory organs need them to combat infection. The tea catechols are tremendously important in treating radiation disease. Radioactive isotopes, in particular Strontium-90, may cause serious illness. Japanese scientists recently determined that tea catechols had absorbed Strontium-90 isotopes before they penetrated the bone tissues, and could thus save the organism from perishing. It was found out that most of the victims of Hiroshima and Nagasaki had died not from the blasts but from radiation disease. Japanese scientists became interested in this phenomenon and experimented on animals injected with Strontium-90. The results were sensational. It must be admitted that the organisms of the control animals contained a considerable amount of Strontium-90, while the animals which had been treated with tea catechols had no malignant isotopes in their organisms at all.
