Salix nigra bark of the tree contains salicylic acid, a chemical compound similar to aspirin (acetylsalicylic acid). It may also be used as an environmental restorative. Swamp trees in general are, by necessity, good at surviving and thriving in areas where highly mobile environmental toxins are present. Black Willow is very resistant to herbivory and flooding and is also a fantastic erosion control tool. Thus, it is useful for any sort of marshland stabilization or restorative as long as the roots don’t penetrate any clay liner that may be in place. In a relatively extensive phytoremediation study, "Salix nigra" demonstrated some success
Quinic acid Quinic acid Quinic acid is a cyclitol, a cyclic polyol, and a cyclohexanecarboxylic acid. It is a colorless solid that can be extracted from plant sources. Quinic acid is implicated in the perceived acidity of coffee. The compound is obtained from cinchona bark, coffee beans, the bark of "Eucalyptus globulus". It is a constituent of the tara tannins. Urtica dioica is another common source. It is made synthetically by hydrolysis of chlorogenic acid. Quinic acid is also implicated in the perceived acidity of coffee. This substance was isolated for the first time in 1806 by French pharmacist Nicolas Vauquelin and
