In China, tea has been valued for its beneficial effects for more than a thousand years. It may even have been used in cooking and as a medicine before it became a drink. Today, it seems to be generally accepted in modern research that the caffeine in tea stimulates the nervous system as well as the respiration system and that both theophylline and theobromine found in tea increases muscle relaxation and coronary dilation and stimulates the heart. Modern research is also particularly interested in health benefits of green tea, and its various “antioxidants”.
However, be aware that each tea is an individual, like a human being. How “tea” may effect your body depends on a number of different factors that rarely are explained in ads and research: what is the kind of tea that has been tested, what was the quality of the tea leaf, where the tea was grown, the age of the tea leaf, how was it produced, the storage, the amount, the steeping time, water temperature etc. All these factors, and many more, influence the effects on both body and mind of the tea we drink. Even the surrounding of where we drink tea effects us, as you will know yourself when you start “feeling” the tea, seeking to know tea beyond its taste and fragrance.
If we drink tea attentively and trust the responses of our body and mind, we can start to teach ourselves about the properties of the particular tea we drink. That way we can ourselves find the quality and quantity that is most suitable for us and thus increase our appreciation and knowledge of tea.
