Shennong Materia Medica no longer exists, and now it is a compilation of Huangxuan in Qing Dynasty. The earliest materia medica is the Materia Medica of Political, Economic and Historical Evidence compiled in the Song Dynasty, which has gold editions and gold editions in the Ming Dynasty. The former has a photocopied edition of China Remanufactured Rare Books with a price of nearly 9000 yuan, while the latter has four series of photocopied editions and hardcover editions reprinted by Shanghai Bookstore.
Treatise on Febrile Diseases includes Amin edition, four photocopies and hardcover edition reprinted by Shanghai Bookstore.
None of the above is easy to find now, but four series of electronic versions are available online!
