This large-sized plant stands out structurally due to its spectacular erect inflorescences, consisting of large, white flowers with a labellum intensely colored in bright shades of yellow and red, cultivated in tropical regions as a premium ornamental plant and for the essential oil extracted from its leaves and rhizomes.
- Anethole — An aromatic organic compound, an unsaturated ether of the phenylpropene class, constituting the primary component of the essential oil extracted from anise, fennel, or star anise. In a technical and structural sense, it presents as an oily liquid or white crystals with a characteristic sweet odor and strong aromatic taste, widely used in the perfume industry, alcoholic beverages, and in medicine as an expectorant.
