The patients orally self-administered 1 gram of Qing Dai (Indigo Naturalis) powder, 2 times per day for 4 months. The results of the herbal program demonstrated significant clinical and objective improvements such that 6 of the 7 patients completely discontinued the use of prednisolone, a corticosteroid used to control ulcerative colitis. The researchers examined Qing Dai to learn more about its effective mechanisms of action. Using electron spin resonance, they discovered that Qing Dai has potent hydroxl radical scavenging activity. This discovery prompted the researchers to recommend further investigation into the mechanisms of Qing Dai’s anti-inflammatory effects.
This research coincides with other recent research demonstrating that acupuncture and herbal medicine are effective in the clearing of chronic ulcerative colitis. Published in the Clinical Journal of Chinese Medicine, the study showed that a combination of herbal enemas consisting of Ku Shen and Bai Tou Weng combined with an acupuncture treatment regime was significantly more effective than taking antibiotics for resolving ulcerative colitis.
The Qing Dai study highlighted specific clinical results of its participants. One patient vignette was of a man suffering from ulcerative colitis with hematochezia, the passage of fresh blood through the anus. This patient had taken antibiotics and prednisolone to control the hematochezia. However, he was unable to reduce the dosage of prednisolone without the return of hematochezia. Over time, the patient needed to increase the drug dosages to maintain clinical results and he showed no clinical improvements in his baseline condition. After 3 years, he began the Qing Dai treatments and after one month the hematochezia resolved completely. Objective testing also showed a marked decrease in serum C-reactive protein levels. The patient was able to discontinue the use of all drugs. Endoscopy revealed that his ulcers completely disappeared. A follow-up confirmed that the therapeutic effect of Qing Dai therapy lasted for more than 2 years.
