An ancient Chinese treatise says: “Tea strengthens the spirit, softens the heart, removes fatigue, awakens the mind and does not allow laziness to settle, lightens and refreshes the body and clarifies receptivity.” These healing properties of tea, known since ancient times, are still successfully used today. In China, for example, tea, before becoming an everyday drink, was used for a long time only as a remedy for many diseases: it was believed that it relieves headaches, strengthens strength, and improves vision. Healing decoctions and pastes were prepared from tea, and poisoning was treated. Green tea has now gained particular popularity all over the world. It became the subject of in-depth study, as a result of which its healing properties, known for a long time, were confirmed. It acts gently and harmlessly, improving overall health, increasing stamina and immunity.
