Ethnopharmacological Properties of Swertia chirayita and Other Species: A Nature’s Treasure

<i>Swertia chirayita</i> (Family; Gentianaceae) is a well-known medicinal plant from the temperate Himalayas and is used in traditional medicine to treat a number of illnesses, including liver issues, malaria, and diabetes. The medicinal use of S. chirayita is extensively documented in the Indian Pharmacy Codex, the British and American Pharmacopoeias, as well as in a number of traditional medical systems, including Ayurveda, Unani, and Siddha. This plant's primary distinguishing feature is its bitter flavor, which arises from the presence of several bioactive compounds that may offer health benefits to people. Growing demand for this important medicinal plant on a national and international scale has prompted unethical wild harvesting and adulteration of the supply. Consequently, there has been a sharp decline in the plant's population, putting it at risk of extinction. Therefore, the objective of this chapter is to give a summary of recent discoveries in the areas of morphology and distribution, traditional usages, biotechnology, phytochemistry, pharmacological effects, and safety evaluations of S. chirayita.
