用小鼠热板法研究了洋金花对吗啡镇痛作用耐受性的影响。洋金花能明显阻止连续应用吗啡出现的镇痛作用耐受性的发展，恢复小鼠对吗啡镇痛作用的敏感性。表明洋金花对阿片类物质成疒隐可能具有较好的治疗作用 The effect of Drosophila on the tolerance of morphine analgesia was studied by mouse hot plate method. Dendrobium can significantly prevent the development of tolerance to analgesic effects of continuous use of morphine and restore the sensitivity of mice to morphine analgesia. Shows that goldenrod may have a better therapeutic effect on opioids
