'Cananga' is a genus of tropical trees in the family Annonaceae, which is native to Southeast Asia. The most well-known species in this genus is Cananga odorata, also known as ylang-ylang. This tree is widely cultivated for its highly fragrant flowers, which are used in perfumes, aromatherapy, and traditional medicine.

The flowers of Cananga odorata have a sweet, exotic, and slightly fruity scent that is often described as being both floral and woody. They contain several fragrant compounds, including benzyl acetate, linalool, geranyl acetate, and methyl benzoate, which contribute to their unique aroma.

In traditional medicine, the flowers of Cananga odorata are used to treat a variety of conditions, including anxiety, depression, high blood pressure, skin conditions, and insect bites. They are also believed to have aphrodisiac properties in some cultures. However, it is important to note that while there is some scientific evidence to support the use of ylang-ylang essential oil for certain conditions, more research is needed before any definitive conclusions can be drawn about its effectiveness or safety.
