Gout tree, scientifically known as Ailanthus altissima, is a medium-sized to large deciduous tree that belongs to the Simaroubaceae family. It is native to Northeast and Central China but has been widely introduced and naturalized in many parts of the world.
Gout tree derives its common name from the belief that it can exacerbate the symptoms of gout, a type of arthritis characterized by sudden and severe joint pain. However, its association with gout is not scientifically proven.
The tree has a distinctive appearance with compound leaves that can reach up to three feet long. The leaflets are arranged in odd-pinnate fashion and emit a pungent odor when crushed. The bark of the gout tree is smooth and grayish-brown, while the branches are often greenish in color.
Gout tree is known for its vigorous growth and invasive tendencies, being able to thrive in disturbed environments, roadsides, and wastelands. It has a shallow root system that contributes to its ability to establish itself in various soil conditions. Female trees notably produce large clusters of winged seeds that can be dispersed by wind over long distances.
While considered an undesirable species in certain regions due to its invasive nature, gout tree has been utilized in certain cultures for its medicinal properties. Various parts of the tree, including the bark, leaves, and fruits, have been employed in traditional medicine to treat ailments such as dysentery, asthma, and rheumatism. However, it is important to note that the efficacy and safety of such uses have not been extensively researched or endorsed by modern medical practices.
