In Chinese and Vietnamese folk medicine, practitioners prepared remedies for bronchitis using sun-dried, immature wampee fruits as well as thin slices of the roots. Decoctions of the leaves were traditionally employed as a hair wash intended to address dandruff and preserve hair color. In China and Malaysia, herbalists utilized the leaves for conditions such as asthma, coughs, and skin complaints, while folk traditions in Taiwan employed the roots for bronchitis.

Folk belief also attributed stomachic, cooling, and vermifuge qualities to the fruit, and in Chinese dietary tradition, it was consumed on a full stomach to counteract the perceived ill effects of eating too many lychees. Beyond medicinal applications, the ripe peeled fruit was eaten fresh, served alongside meat dishes, included in desserts, or preserved into jams and jellies. In Southeast Asia, the fermented fruit juice was sweetened to produce a carbonated beverage, and the plant itself was historically cultivated as a hedge or privacy screen due to its dense foliage.
