Any assessment or diagnostic technique that seeks to make sense of what’s happening inside the human system is inherently pretty complex – be it a modern tool such as a CT scanner, or a traditional device such as the stethoscope. Interpretation is tricky, and the background knowledge required can often be intimidating. While using the tongue and pulse to get a glimpse inside the human body is not an exception, one can nevertheless glean really useful, actionable information with even a basic understanding of the technique. This basic understanding can become richer and deeper with ongoing practice. The complexity evidenced in traditional texts on the subject should not be a reason to keep you from experimenting!
