Chinese bitter orange

Citrus trifoliata, commonly known as trifoliate orange or sour orange, is a traditional plant primarily associated with East Asia and parts of North America. Traditionally, it has not been extensively used in medicine or folklore, though its cultivation for citrus fruits and ornamental purposes is well-documented. Scientific research on Citrus trifoliata has focused largely on its genetic and physiological aspects rather than medicinal uses. Studies have identified key regulatory modules that enhance the plant's salt tolerance and nitrogen use efficiency through mechanisms involving chloride sequestration in vacuoles and nitrate efflux. Additionally, research has explored how genome editing can modify bitter flavanone synthesis while preserving beneficial flavonoids. Leaf sugar profiles under water stress conditions have also been examined following inoculation with Funneliformis mosseae. While the scientific evidence is limited to these specific areas of study, no major safety issues or drug interactions have been recorded for Citrus trifoliata.
