Salvadora persica, commonly known as the toothbrush tree, is a small tree or shrub native to parts of Africa and the Middle East. It typically grows in arid regions and can reach heights of up to 5 meters. The tree produces small, edible berries and has leaves that are often used for traditional dental hygiene. The twigs of Salvadora persica have been used for centuries as a natural toothbrush due to their antimicrobial properties. This practice is common in many cultures, particularly in Saudi Arabia and India, where the tree is valued for its health benefits and sustainability.
