Liu, female, 68 years old. She was diagnosed with pelvic abscess several times and the pain was relieved after antibacterial treatment, but the pelvic abscess was not easily absorbed. Six months ago, she came to the clinic and used herbs to warm Yang, activate blood circulation, resolve phlegm and disperse nodules for one month, and the pelvic abscess was completely absorbed by ultrasound. 10 days ago, the patient came to the clinic again, complaining of another pelvic abscess, abdominal cramps, no fever, no abdominal pain, and after one week of anti-inflammatory treatment, the effect was not obvious, and the blood routine showed a high total white blood cell count (13.3) suggesting that the infection still existed. The patient’s tongue is light and fat with white greasy coating. The patient’s tongue was pale, fat, and greasy with white fur. It showed a sign of Yang deficiency and cold dampness. The patient was still treated with herbal medicine to warm Yang, invigorate Blood, resolve phlegm and disperse nodules. 3 days before taking the medicine, she had loose stools, several lines a day, while her energy remained normal. One week later, the total white blood cell count (7.64) was rechecked. The inflammation was significantly improved. He is still taking medication for treatment. This case once again reflects that TCM treatment should be evidence-based, and one should not clear heat and detoxify abscesses as soon as one sees a high blood count. As long as the evidence is accurate, warming Yang can also reduce inflammation.
