Herbs that Release the Exterior

1/10

According to Shang Han Lun theory, what is the order in which cold pathogens penetrate the six levels (from superficial to deep)?

Tai Yang, Yang Ming, Shao Yang, Tai Yin, Shao Yin, Jue Yin
Yang Ming, Shao Yang, Tai Yang, Jue Yin, Shao Yin, Tai Yin
Tai Yin, Tai Yang, Shao Yin, Shao Yang, Jue Yin, Yang Ming
Tai Yin, Shao Yin, Jue Yin, Tai Yang, Yang Ming, Shao Yang

The Tai Yang level is the most superficial level and is the first to get hit by an exterior attack. The Taiyang channel (UB + SI) go to the neck and shoulders, and that's why neck and shoulder stiffness are a sign of an external attack.
