Based on these philosophies, Zhen Jiu(acupuncture), Ben Cao(materia medica), and the practice of Qi Gong(energy optimization movements) evolved as the three interrelated therapeutic regimens of Chinese medicine(Note 1). Since the time of Zhang Qian, who discovered China's western regions in the 1st century BCE, Hai Yao(the exotic elements of materia medica from the maritime Silk Road countries), had been transmitted from the ancient land and maritime routes of the Silk Road to China in the past two millennia(Note 2). Since the late 17th century, the English East India Company, later called the British East India Company, introduced Yang Yao(opium) to the Manchu Qing Empire to balance a growing trade deficit for tea export from China to the British Empire. After the First Opium War ended in 1842, enterprising expatriate chemists and druggists in the treaty ports imported Xi Yao(modern medicines from the Western world) for sale to the merchant navy and the local market. From the second half of the 19th century onwards, both Hai Yao and Xi Yao have become a fully integrated part of modern China's armamentarium for the Chinese medicine and Western hospitals and retail pharmacy sectors. This paper articulates the journey of adoption of exotic elements of materia medica from the ancient land and sea routes of the Silk Road, including the western regions and the rest of the world in the past two millennia. Opium traders, ship surgeons, medical and pharmaceutical missionaries, enterprising traders, and policymakers together transformed Ben Cao into Xi Yao during the late Manchu Qing dynasty and the early Nationalist Era.展开更多

This paper studied the historical background, academic characteristics, editions, and significant contributions to traditional medicine of De Materia Medica and Dioscorides. It was concluded that the book has substantial scientific importance and remarkable cultural attributes. De Materia Medica of Dioscorides has both nourished world traditional medicine and promoted the communication and development of medicinal knowledge worldwide. It is significant for us to explore further the related understanding of traditional medicine, history, society, and culture.展开更多

Methods: This was a retrospective observational study conducted from January 2011 to June 2022. The patients included were of all ages and both sexes in whom the sine materia nature of the pruritus was noted after clinical examination. These patients had an etiological assessment available or not, complete or partial. For each patient, socio-demographic, socio-cultural, socio-economic and clinical data were collected using a pre-established survey form. They were then processed and analysed using Epi Data 3.1 and SPSS version 21 software respectively. Results: The incidence of generalised pruritus sine materia was 0.89% (73 cases/8214 consultants). The predominant etiologies were aquagenic pruritus (16.4%) and intestinal parasitosis (12.3%). After a bi-variate analysis, two risk factors were identified: frequency of towel change greater than 1 month (OR = 3.02;CI<sub>95%</sub> = 0.98 - 9.31;P = 0.0486) and use of cold water for bath (OR = 3.28;CI<sub>95%</sub> = 1.09 - 9.81;P = 0.0274). Conclusion: The etiologies and associated factors of generalised pruritus sine materia found in Parakou are varied but are linked to lifestyle. There is an urgent need to raise public awareness of the need to improve lifestyle in order to reduce the frequency of pruritus sine materia. .展开更多
