Journal of Zhejiang Chinese Medical University 2015;(10):753-755
Objective] To explore the clinical experience of Ma Weiming in the treatment of insomnia.[Method] By following the teacher clinic, the author summarizes chief physician Ma Weiming’s academic experience of treatment of insomnia with classical prescriptions. [Results] In Ma Weiming's opinion, everything harasses the heart, mind vacillation, inducing liver ’s function of storing soul abnormal, the spirit restless is due to insomnia with much dream. So teacher Ma pays attention to “dream diagnosis”.The treatment of insomnia must be combined with heart and liver, making the mind quiet and the liver comfortable. He likes using flowers to balance Qi. In Ma Weiming's opinion, collaterals are invaded by prolonged illness, due to blood stasis. The treatment should use insect drugs to dispell wind and remove obstruction in the meridians, purifying orifices, promoting sleep. [Conclusion] According to the etiology of insomnia to distinguish among different dreams, teacher Ma uses classical prescriptions and combines with his own unique clinical experience on treating insomnia, which has significant effect and worth generalizing.
