The peelu tree, also known as Salvadora persica, is a small, deciduous tree native to the dry regions of Africa, the Middle East, and South Asia. It grows to a height of about 7 meters (23 feet) and has a twisted, gnarled trunk and small, spiky leaves. The peelu tree is known for its antimicrobial and astringent properties, and the twigs and bark of the tree are traditionally used as a natural toothbrush in many parts of the world. The tree is also used for medicinal purposes, including the treatment of digestive problems and as an expectorant to help clear congestion in the respiratory system.
