ปัตตาเวีย (Patta Wia)
Family: Euphorbiaceae Jatropha multifida, commonly called the Coral Plant, is a striking tropical shrub with deeply divided leaves and vivid coral-red flower clusters. Native to Central America and naturalized across Southeast Asia, it has become an ornamental and medicinal species valued for its resilience and distinctive beauty. Like other Jatropha species, it contains a milky sap that must be used with care due to its irritant properties.Botanical Characteristics
This semi-succulent shrub typically grows 2–3 meters tall with a single straight trunk and smooth gray bark. The leaves are palmately divided into 7–11 narrow lobes, giving the plant a lacy appearance. Bright red flowers form in umbrella-shaped clusters at the branch tips, attracting butterflies and bees. The sap is characteristic of the Euphorbia family—sticky, white, and mildly toxic if ingested or applied undiluted.Use in Thai Traditional Medicine
In Thai traditional medicine, ปัตตาเวีย (Patta Wia) is used primarily for external treatments. The leaves and sap are applied to relieve inflammation, insect bites, and minor wounds. Crushed leaves may also be used to reduce swelling from sprains. Despite its medicinal potential, internal use is avoided due to the presence of toxic compounds similar to those found in castor oil plants (Ricinus communis).Cultivation Notes
Jatropha multifida thrives in full sunlight and well-drained soil. It tolerates drought and salt exposure, making it suitable for coastal and tropical gardens. Propagation is typically through stem cuttings, and pruning after flowering helps maintain shape. At Kamala Beach Estate’s Thai Medicinal Herb Garden, the Coral Plant is used as an educational example of the boundary between healing and toxicity in herbal medicine.Historical Context
Introduced to Asia through colonial botanical exchanges, the Coral Plant quickly gained popularity for its ornamental beauty and medicinal properties. Traditional healers in Thailand and the Philippines have long recognized its potential in topical remedies, while modern studies continue to explore its antimicrobial and anti-inflammatory compounds.Disclaimer: This information is provided for educational and historical purposes only.
