Song Xiaodong did indeed want to deceive for the Fire Spirit Grass, but to regulate Alicia's body is surely not an easy task. Apart from needing acupuncture, some medicine is also required as assistance.
Acupuncture! Acupuncture actually consists of two medical techniques, divided into acupuncture technique and moxibustion technique. The acupuncture technique is like how Song Xiaodong usually uses silver needles to pierce into acupoints, then through twisting or other means, he transfers True Qi into the acupoints to achieve a therapeutic effect.
As for the moxibustion technique, it's using incense or something like mugwort to apply combustion or fumigation methods for treatment.
Song Xiaodong was only using acupuncture technique previously, but he is equally skillful in moxibustion technique. However, his moxibustion technique uses silver needles as a medium and utilizes True Qi for combustion, then assists with medicine.
