Safety Overview
1.Toona — Essential Profile
Toona sinensis, universally recognized as Chinese toon or Chinese mahogany, is a majestic deciduous tree belonging to the Meliaceae family, a lineage that also includes notable genera such as Swietenia and Cedrela. This species typically attains an impressive height of 10 to 20 meters, with some specimens exceeding this under optimal growing conditions. Its distinctive foliage consists of pinnately compound leaves, which can measure between 20 and 30 centimeters in length. Each ovate to elliptic leaflet is elongated, ranging from 5 to 10 centimeters long.
The young leaves are particularly prized for their pleasant, unique aroma, making them a sought-after culinary ingredient in East Asian cuisines. In the springtime, Toona sinensis adorns itself with clusters of small, yellowish-green, fragrant flowers, arranged in panicles that can stretch up to 15 centimeters. The bark exhibits a smooth texture in its juvenile stage, gradually developing a fissured, textured appearance as the tree matures. Endemic to East and Southeast Asia, particularly thriving across various regions of China, this species flourishes in subtropical and temperate climates.
It demonstrates adaptability to a range of soil types but shows a clear preference for well-drained, fertile loams. Its natural habitats include forested areas, roadsides, and cultivated gardens, reflecting its robustness and widespread distribution. Beyond its aesthetic and culinary appeal, Toona sinensis has been a cornerstone in traditional medicine systems for its diverse therapeutic applications.
