Treat the pathogen or strengthen the patient?
One of the most interesting debates in TCM/TCVM is whether to focus on expelling the pathogen or supporting the patient's Zheng Qi.
🔹 Classical approach
In the early stages of an external Wind-Cold or Wind-Heat invasion, treatment focuses on releasing the exterior and helping the body eliminate the pathogen. Excessive tonification at this stage may theoretically "trap the pathogen inside."
🔹 Deficiency-based approach
When the patient is severely debilitated, elderly, chronically ill, or unable to mount an effective response, many modern TCM and TCVM authors advocate strengthening Zheng Qi.
A good example is a cat with FIP, abdominal effusion, muscle wasting, and hind limb weakness. From a TCVM perspective, this is not only a pathogen problem — it is also a Zheng Qi problem. In such cases, supporting the spleen, kidneys, Qi, and overall vitality may help the body regain the capacity to respond to disease.
As TCVM teaches:
"Support Zheng Qi without retaining the pathogen. Eliminate the pathogen without damaging Zheng Qi."
