Botanical Characteristics
The tree can grow up to 20–30 meters tall, with rough gray bark and whorled leaves arranged in clusters of 5–8 around each node. Leaves are lanceolate, glossy green above and paler beneath. The plant produces small, fragrant white flowers and slender seed pods containing fine, silky seeds.
Use in Thai Traditional Medicine
The bark and latex are used in preparations to reduce fever, treat malaria, and relieve asthma and chronic cough. Decoctions from the bark are traditionally used as a general tonic to strengthen the body and aid recovery after illness. In folk practice, it is also believed to repel negative energy.
Medicinal Compounds
Contains alkaloids such as echitamine and scholaricine, known for their anti-inflammatory, antimalarial, and analgesic properties. Extracts of the bark and leaves show antimicrobial and antioxidant activity, supporting its traditional therapeutic uses.
Culinary and Nutritional Uses
Alstonia scholaris is not a culinary plant due to its bitter taste and latex content. It is primarily valued for medicinal and ecological purposes, contributing to forest biodiversity and air purification.
Cultivation Notes
