Turmeric's phytochemicals, which include curcuminoids, essential oils, and other bioactive substances, are principally responsible for its therapeutic effects. The Phytochemistry of Curcuma longa is described in this narrative review, with special attention paid to the major classes of phytochemicals and their potential for medicinal use. The therapeutic properties of the curcuminoids, particularly curcumin, as well as their potential to prevent and (...) cure a variety of chronic disorders have all been thoroughly investigated.
