This episode explores whether there's a difference between an external deficiency and a disharmony between Ying and Wei level in Chinese medicine. An external deficiency occurs when a pathogen invades a body with weak defensive Qi (Wei Qi), like soldiers who aren't properly fed and can't guard the borders effectively. A disharmony between Ying and Wei arises when the Wei Qi is weakened and can no longer control the Ying Qi properly, causing spontaneous sweating through the pores. This sweating can take place without the presence of an EPF.Are you still following? It doesn't matter so much whether you know the differences but rather that you understand the mechanism.Enjoy listening :)
