Yin Fire is not just yin deficiency heat, but its own diagnosis, with its own specific treatment strategies. Yin Fire is implicated in many modern-day autoimmune, inflammation-related and difficult-to-treat cases. Treating the Earth first is critical in Yin Fire cases: in the traditional Five Elements diagram, earth is in the center. When earth isn’t holding the ground, e.g. when spleen qi direction is reversed down instead of up, the entire circle collapses. Earth, when it’s the first domino to fall, leads the rest into disarray. If the practitioner does not begin with Earth in treating these complex cases, they can resort to perpetually chasing symptoms perpetually instead of addressing the situation as a whole.
