Abstract

|
Objectives : The aim of this study is to review the topical anesthetic effect of herbal medicine.
Methods : Using domestic database(OASIS, RISS) and foreign database(Pubmed, Embase, Cochrane library, CNKI), clinical studies about efficacy of herbal medicine as topical anesthetics were searched. Only randomized controlled trials(RCT) were selected and analyzed.
Results : Total 647 studies were searched. After screening process, 5 articles were selected. 2 were from Chinese database and 3 were from English database. Articles were about clinical use of herbal medicine as topical anesthetics and compare their efficacy with conventional topical anesthetics. Out of 5 articles, 4 articles used pain rating scales recorded by subjects as outcome measurement. All studies showed lower pain score in herbal medicine using groups. 4 studies showed that there was no statistically significant difference in pain score between herbal medicine using group and conventional topical anesthetics using group.
Conclusions : The results suggest that topical anesthetics using herbal medicine is as effective as or maybe even more effective than conventional topical anesthetics. However, experimental design and composition of intervention were all different, which provides inaccuracy when comparing the experimental results. Also, sample sizes were small and the number of RCTs were insufficient to identify full list of herbs that have potentials to be used topical anesthetics. Further studies need to be conducted to find out potentials of herbal medicine as topical anesthetics.
