Insomnia is a multi-system disorder that afflicts the majority of elderly individuals. Chronic insomnia can increase the risk of mental health issues. Professor Lei Zhengquan, drawing on years of clinical experience, summarizes that the core pathogenesis of age-related insomnia is the deficiency of the Mingmen (Life Gate), leading to disharmony of Qi flow, which in turn causes long-term impairment of visceral functions and subsequently affects sleep quality. The theory of the Mingmen reveals that it is the fundamental source of the Five Zang and Six Fu organs, yet it exists at a level above these organs. Professor Lei integrates and extends the core principles of the Mingmen theory, proposing a combined treatment approach of acupuncture and herbal medicine centered on “nourishing the Mingmen and regulating Qi flow.” This method involves internal use of Chinese herbs to harmonize the viscera and external acupuncture to unblock meridians and facilitate Qi circulation. Such treatment establishes a communication between internal and external Qi, clears the meridians from top to bottom, and links the visceral organs and meridians, thereby balancing Yin and Yang, replenishing Qi and blood, and ensuring smooth flow throughout the body. This comprehensive approach aims to restore health and promote recovery.
