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
Fluoroacetic acid Fluoroacetic acid Fluoroacetic acid is a chemical compound with formula CHFCOOH. The sodium salt, sodium fluoroacetate, is used as a pesticide. It inhibits the aconitase step of the citric acid cycle. Fluoroacetate occurs naturally in at least 40 plants in Australia, Brazil, and Africa. It is one of only five known organic fluorine-containing natural products. It was first identified in "Dichapetalum cymosum", commonly known as gifblaar (Afrikaans) or poison leaf, by Marais in 1944. As early as 1904, colonists in Sierra Leone used extracts of "Chailletia toxicaria", which also contains fluoroacetic acid or its salts, to poison rats. Several native
