Although the slow growth of guaiacum trees contributes to the oil's distinctive properties, it also limits the supply of guaiacwood oil and raises questions about sustainability. The sustainability of the guaiacum tree populations can be impacted by overharvesting or unethical sourcing methods. Guaiacwood oil's availability and pricing can fluctuate because of its limited supply and probable difficulties in planting and harvesting. Variations may be caused by elements including the weather, geopolitical events in the production regions, and consumer demand.
