Pulosari (Alyxiar einwardtii atau Alyxia stellata)

Coumarin is the main aromatic compound that provides a distinctive fragrance and mild calming effect, while tannins are astringent substances that play an important role in maintaining digestive health. In addition, alkaloids function as bioactive components that contribute to antimicrobial activity. Equally important, pulosari also contains alyxialactone, a specific compound found in its cortex or bark.

Coumarin compounds are a group of secondary metabolites in plants known to have various pharmacological effects, including anti-inflammatory, antioxidant, antiallergic, antithrombotic, antiviral, and anticancer activities. In addition, research findings show that fennel plants have antibacterial activity against V. cholerae, making them potentially useful in helping to treat diarrhea caused by this bacterium.
