Batino
Also known as: Hard alstonia · Hard milkwood · Big-leaved alstonia
Definition
Batino is the Philippine name for Alstonia macrophylla, a tree of the dogbane family Apocynaceae also known in the timber trade as hard alstonia, hard milkwood, or big-leaved alstonia. Native to Southeast Asia including the Philippines, it is a fast-growing tree with conspicuously large whorled leaves, yielding a light hardwood and traditional medicinal preparations.

Examples and Analogies
The batino is the soft-wooded pioneer of Philippine second-growth forest in the same way birches colonize cleared temperate land: after logging or slash-and-burn, its wind-blown seeds and big leaves let it shoot upward quickly, clothing disturbed slopes years before slower hardwoods return.
Usage Scenarios
Farmers and foresters use it for quick shade and as a nurse crop in tree plantations, its light timber serves for boxes, matches, pulp, and core veneer, and in folk medicine the bitter bark and latex are prepared as remedies, with related Alstonia species supplying the medicinal “dita” bark of Philippine pharmacies.
Strategies
As an early-successional native it is well suited to assisted natural regeneration, where protecting seed trees on fallow land lets batino recolonize without planting costs, stabilizing soil while more valuable late-successional species re-establish beneath it.
Security and Safety Measures
No formal protection is required for this common pioneer, but sustainable harvest practice keeps batino stands as habitat connectors in farmland mosaics, and medicinal use follows traditional preparation since the plant’s latex-bearing tissues warrant respect.
Historical Context
The genus Alstonia honors the British botanist Charles Alston, and Philippine species have long entered both the timber stream and the traditional pharmacopoeia, with batino notable in postwar forestry as an indicator species for secondary forest recovery.
Challenges and Controversies
Its low timber price encourages clearance in favor of crops, removing the very tree that most cheaply restores degraded land, and unverified medicinal claims about Alstonia bark circulate alongside legitimate ethnobotanical knowledge.
