Botanical Overview
Frangipani (Plumeria acutifolia) is a flowering plant in the Apocynaceae family. This plant has earned a place in traditional medicine through its consistent therapeutic benefits, recorded across multiple cultures. The dogbane family (Apocynaceae) includes herbs, shrubs, vines, and trees with milky sap containing alkaloids and cardiac glycosides. The flowers are typically five-petaled and often showy with a tubular corolla. Many species in this family are highly toxic but also source of important cardiac medications.
General Description
Originally native to Mexico, Central America, Colombia and Venezuela, it has been widely cultivated in subtropical and tropical climates worldwide and is a popular garden and park plant, as well as being used in temples and cemeteries. It grows as a spreading tree to 7–8 m (23–26 ft) high and wide, and is flushed with fragrant flowers of shades of pink, white and yellow over the summer and autumn.

Traditional Uses
Frangipani has been traditionally used for digestive health, respiratory conditions, and skin and wound care, among other applications.
Digestive health.
- Purgative
- Diarrhea
- Laxative
For digestive complaints, the herb is typically prepared as a tea or decoction taken before meals. The bitter compounds stimulate digestive secretions and improve nutrient absorption. Some traditions use the powdered root or leaves in small doses as a stomachic tonic.
Respiratory conditions.
- Cough

Skin and wound care.
- Sore
- Skin
- Wound
For skin conditions, the fresh or dried plant is applied topically as a poultice, wash, or compress. A strong decoction can be used to clean wounds and sores. The antimicrobial properties help prevent infection while promoting tissue repair.
