so far from what I gather on the net, yes, the honeysuckle here in the South that grows out of control is the invasive species Japanese Honeysuckle. Check out pictures on the net just to make sure yours is the same.
Anyway, it has been used forever in Chinese Med for a number of things. It seems mostly the dried flower blooms early in the summer are used for tea. I wish I could find info about the leaves because this damn plant stays green most of the winter.
But, just think if they found a wonderful cure for some awful disease. You would have yourself a motherload of those damn leaves:-)
