Safety Information
Toxicity Details
The living tree is non-toxic. All parts including leaves, flowers, and seeds are safe if ingested in normal amounts. However, teak is well-known for causing significant occupational health issues in woodworkers.
Skin Contact Risks
Fresh plant parts generally safe. Some individuals may experience mild skin irritation from leaves or sap. Wood sawdust can cause dermatitis in sensitive individuals.
Allergenic Properties
WOOD DUST HAZARD: Teak wood dust is a potent respiratory sensitizer and allergen. Woodworkers commonly develop allergic reactions including asthma, rhinitis, and dermatitis. Dust contains quinones (tectoquinone) that cause sensitization. Long-term exposure can lead to chronic respiratory issues. Proper dust collection and respiratory protection REQUIRED when working with teak wood. Not a concern for living tree.
Wildlife & Pet Risks
Safe for wildlife and livestock. Leaves are browsed by deer and livestock without harm.
Teak
Teak (Tectona grandis) is arguably the world's most prized tropical hardwood, renowned for its exceptional durability, natural resistance to rot and insects, and beautiful golden-brown color. Though native to Asia, Costa Rica has become a major producer of plantation teak, with extensive forests in Guanacaste and the Northern Zone.

Animals in teak plantations:
While teak provides economic value, pure plantations support far less biodiversity than native forests. Sustainable forestry practices in Costa Rica increasingly incorporate wildlife corridors and mixed plantings.

Physical Properties
Teak's legendary durability comes from its high natural oil content and silica deposits. It resists rot, fungi, termites, and marine borers like no other wood, making it ideal for boats, outdoor furniture, and any exposed application.

Wild vs. Plantation teak:
While wild teak is endangered in its native range, plantation-grown teak from Costa Rica and other countries provides a sustainable alternative. Look for FSC (Forest Stewardship Council) certification when purchasing.

Teak (Tectona grandis) represents the pinnacle of tropical hardwoods—its combination of beauty, durability, and workability is unmatched. While wild populations are endangered in Asia, Costa Rica's sustainable plantations demonstrate how responsible forestry can meet global demand while creating economic opportunity. Every teak deck and piece of outdoor furniture from Costa Rica represents a renewable harvest rather than forest destruction.
