Spring, after a winter long of saving energy, it's time to sprout, "spring" out from the enclosures. Flowers bloom, creation of seeds. It's the energy of creation, vitality and life. Because of this energy, Spring teas are particularly alive and active. Youngsters in teens and 20's are also considered "spring" in human life span. Therefore the energy of a young person and Spring teas goes hand in hand, hence you'll find younger people handle fresh green/green oolong teas better than matured people. People in 50's and 60's, on the other hand may find the energy too active, tell tails are stomach upset, break outs, increase heart beats.
Assuming we live 80 (national average) years, divide 80 by 4, each 20 years is a season. However, human has the potential to live 120 to 140 years. So 20 to 30 years is a season in human life depending on the person's health condition. In Chinese medicine terms, what keeps the body alive is Qi and blood, Qi is the energy that pushes blood circulating. Qi is stronger at younger age, as we all know younger people are more energetic.
Many customers of mine asked me why do they have upset stomachs after drinking green teas, and the outrage is "If green tea is so good for you, why do I get upset stomach?" The mass population follow the most current trends, when the media say green is so and so good for health, they must be good for everybody equally. However it isn't true. Each body is different from another, it's different from it's own at each season, each mood, each hour of the day, each stress we face. The media also show science results of selected teas, not all teas by season, region, grade, type, and age. The results are measured base on a standard condition, rather than suitability of a human body condition at various times.
When it comes to selecting a tea, there isn't a best tea for health. There is better tea by grade, but not for health. Therefore green tea is not the best tea out of all for health as most customers of mine assumed. I tell my customers not one tea is suitable for everybody. Select a type that your body agrees with. Our bodily mechanism is much more intelligent than our own brain when it comes to health and what is better for our body.
