I suspect that you might find some articles in the archives on Global Tea Hut (
http://archive.globalteahut.org/) or The Leaf (
http://www.the-leaf.org/Issues.html).
General tea blogs sometimes post things about the nature of tea as well. For example:

I assume that you're looking for information from a traditional Chinese medicine perspective, but without looking for medical advice as such (which I don't think anyone here would be able, willing or qualified to give, and which I certainly wouldn't pretend to give).
I don't practice or understand traditional medicine, daoism, qigong, or similar concepts, but my own experience has been consistent with what others tend to write about with respect to tea through those lenses, and I treat such descriptions as reflecting how tea affects people in a general sense, without ascribing to the concepts of "qi" or traditional medicine.
That is, my body tends not to enjoy green styles of tea nearly as much as roasted or aged teas, and, as I often say, I find young raw puer to be poisonous to my constitution. I also enjoy the feelings that good quality roasted tea and old tea can give me, whereas I find that young tea and 'green' tea can make me feel uncomfortable. Young puer in particular could make me feel physically unwell.
I couldn't say whether someone else might feel the same way that I do, of course, but I do feel that there is some merit in appreciating that different teas can affect us in different ways, and to bear that in mind to some extent when deciding what to drink. It's not just about the flavour.
