Results support Wenjing decoction (a traditional Chinese medicine) clinical use in treating primary dysmenorrhea.
The study aimed to assess the clinical effectiveness of Wenjing decoction, a traditional Chinese medicine used for primary dysmenorrhea in East Asia, through a systematic review and meta-analysis. Using eight databases, the researchers conducted a comprehensive search and included 18 studies involving 1736 patients in the analysis. The results indicated that Wenjing decoction showed significant superiority over nonsteroidal anti-inflammatory drugs in improving primary dysmenorrhea based on clinical effectiveness rate, visual analogue scale, and pain scale for dysmenorrhea. These findings supported the use of Wenjing decoction for treating primary dysmenorrhea; however, the evidence quality was deemed low due to a high risk of bias in the included studies. As a result, the study emphasized the necessity for well-designed randomized controlled trials to further validate the efficacy of Wenjing decoction for treating primary dysmenorrhea
