Wu Buwei's statement echoed some of Du Heng's own speculations.
"There is indeed such a possibility. With enough accumulation, the profit would be terrifying."
"I remember that radix inulae and sojutsu var. look very similar after slicing. Non-professionals can hardly tell the difference. Furthermore, their medicinal effects are similar, so even if they were to swap one for the other, they wouldn't be afraid of being discovered."
Wu Buwei looked at Du Heng. "Senior brother, what do you plan to do about this?"
Du Heng shook his head gently, not continuing on that topic. Instead, he pointed to the decoction room. "If you don't want to read, go get the medicine. Let the patient take it, and then they can go home."
The patient's initial condition wasn't severe, but issues with the medication had delayed recovery and led to this situation.
Now, with both Decoction medicine and acupuncture, the patient's condition was brought under control after two rounds of treatment.
