Has anyone read this book? And if so, is the information good? From what I've seen(very short research) it seems to be a very influental TCM Medicine Book.

Are you referring to the Shang Han Lun?

The correct translation for the title is Treatise on Cold Damage..

But it seems some modern authors have adjusted it to suit a more fitting description.

I have read most of the Shang Han Lun..

The information is fantastic however it does assume a significant foundational knowledge of tcm and herbs
