Thevetia Peruviana is a plant species commonly known as "yellow oleander," "lucky nut," or "be-still tree." The tropical evergreen tree belongs to the dogbane family and grows up to 20 feet tall. Its yellow or white flowers bloom in clusters and are highly fragrant. The plant, which is native to South America, is frequently used in traditional medicine as a natural remedy for various ailments. However, it can be highly toxic if ingested, as it contains cardiac glycosides that affect the heart. The tree has numerous other synonyms, including "Indian oleander," "Mexican oleander," and "poison nut".
