Origin
China
Ancient Chinese texts such as the Shennong Bencao Jing record the medicinal use of Periploca sepium roots for joint pain and inflammation, and note their aromatic smoke when burned as incense. By the Tang dynasty, court alchemists mixed the plant's distilled essence with sandalwood to create refined scent blends for royal ceremonies. The practice spread to neighboring regions, where herbalists prized the oil for its clean, herbaceous aroma.
In the early 20th century, Western chemists documented the plant during botanical expeditions in Sichuan, and the first perfumery trials appeared in Chinese fragrance houses in the 1930s. Modern niche perfumers cite the oil as a bridge between traditional medicine and contemporary scent design, preserving a lineage that spans more than a millennium.
