About boya: Agarwood Grades and Distillation

Agarwood is graded based on resin content, with “Boya” being one of the grades extracted through hydro-distillation.
Other grades, like “Boha” and “Khara,” may also be extracted using similar methods.
The quality and aroma of the oil can vary based on the wood’s origin, age, and the extraction method used.
