Botanical Description
Citrus aurantium (bitter orange, Seville orange) is an evergreen tree in the Rutaceae family, typically reaching 4-10 m in height with a dense, rounded crown and stout, often spiny branches. The leaves are alternate, ovate to elliptic, glossy dark green, 7-10 cm long, with broadly winged petioles. Flowers are white, intensely fragrant, borne singly or in small axillary clusters, with five waxy petals and numerous stamens. The fruit is a hesperidium, 7-8 cm in diameter, with a thick, rough, bitter rind that turns orange at maturity and pulp divided into 10-12 segments containing acidic juice and numerous seeds. Zhi Shi is the dried immature (unripe, green) fruit, harvested in summer before ripening (POWO; PFAF).

Cultural & Historical Context
Traditional Chinese Uses
Zhi Shi (immature bitter orange) is among the most forceful Qi-moving herbs in the Chinese materia medica, capable of powerfully breaking up Qi stagnation and food accumulation in the Stomach and Intestines. It relieves severe bloating, abdominal fullness, chest congestion, and constipation, especially in constitutionally robust patients. Due to its strong downward-draining and dispersing action, it is generally prescribed for short-term use and avoided in those who are weak, pregnant, or elderly.
