한약: 두 판 사이의 차이

Regarding Traditional Chinese herbal therapy, only few trials exist that are considered to be of adequate methodology by modern western medical researchers, and its effectiveness therefore is considered poorly documented.[34] For example, a 2007 Cochrane review found promising evidence for the use of Chinese herbal medicine in relieving painful menstruation, compared to conventional medicine such as NSAIDs and the oral contraceptive pill, but the findings have to be interpreted with caution due to the generally low methodological quality of the included studies (as, amongst others, data for placebo control could not be obtained).[35]<ref>^ Zhu, Xiaoshu; Proctor, Michelle; Bensoussan, Alan; Wu, Emily; Smith, Caroline A (2008).
