Originally published in 1913, this book contains a detailed treatise on Shô-Gyu oil. "Sho-Gyu" is the name given to an essential oil with an aromatic odour, distilled from a perennial tree native to Taiwan. With the original maps and photographs, this vintage book will appeal to those with an interest in botany and essential oils, and it would make for a worthy addition to collections of allied literature. Contents include: "Sho-Gyu Oil and the Sho-Gyu Tree", "Growing Districts of Sho-Gyu Trees and their Location", "Method Employed in the Preparation of Sho-Gyu Oil", "Yield of Sho-Gyu Oil", "Total Production of Sho-Gyo Oil", "Physical Properties of Sho-Gyu Oil", "Examination of Sho-Gyu by Distillation", "Acid and Ester Values of Sho-Gyu Oil", etc. Many vintage books such as this are becoming increasingly scarce and expensive. We are republishing this volume now in an affordable, modern, high-quality edition complete with a specially commissioned introduction on essential oils.
