Coffer of the Azure-Jade Cinnabar and Cold-Grove Jade-Tree
by 陳大師 (Chén dà shī) — Southern-Sòng Daoist alchemist
A Southern-Sòng alchemical text by the Daoist “Master Chén” on azure-jade cinnabar and the cold-grove jade-tree — poetic names for specific alchemical reactants and products. (Note the source file gives the title’s last character as 匣 xiá rather than 匱 guì; both would signify “coffer.“) Preserved as DZ 898 / CT 898 (Dòngshén bù, Zhòng shù lèi 洞神部眾術類).
