Pattern Diagnosis: Why Two People with the Same Complaint Get Different Herbs
Pattern diagnosis is the engine of Chinese medicine. A complaint such as insomnia is not a disease to match a pill; it is a question, and the answer is a pattern, perhaps heart-yin deficiency, perhaps liver-qi stagnation, perhaps phlegm-heat harassing the mind. Same complaint, different machinery, different treatment. This is also why a herb that transformed your friend's sleep did nothing for yours.
Why it matters in practice
A reader who understands this concept can follow almost any TCM discussion, including the articles on this site, without feeling like a guest at someone else's conversation.
Herbs work best as part of a pattern, not as a solo act. If your symptoms keep coming back, that is the moment to get a proper TCM diagnosis rather than to keep self-prescribing.
