When I was in China, I was surprised to see doctors in the hospital dermatology department using moxa on inflammatory skin lesions. In school I had been taught not to add more heat to an already excess heat condition. I asked the doctors about it, and they explained the concept of using heat to guide heat. Like follows like, and so they added more heat to the exterior of the body to draw out excess heat. It worked remarkably well. It reminds me of the conversation you and I had about guiding pathogens to the nearest available exit - moxa works wonders for this.

yes, exactly, that's a great example of the meaning of 引热外泄 Yǐnrè wàixiè - guiding heat to the outside and discharging it.
