While promising, these uses should complement but not replace standard medical treatment, as further clinical studies are warranted.

Growing and Propagation

Bignay trees thrive in tropical and subtropical climates, and are evergreen with leathery, oval leaves. They adapt well to various conditions and require minimal cultural attention once established.

Key Cultivation Facts
