Lapachol is a natural phenolic compound isolated from the bark of the lapacho tree.^[3] This tree is known botanically as Handroanthus impetiginosus, but was formerly known by various other botanical names such as Tabebuia avellanedae.^[4] Lapachol is also found in other species of Handroanthus.

Lapachol is usually encountered as a yellow, skin-irritating powder from wood. Chemically, it is a derivative of vitamin K^[5]

Once studied as a possible treatment for some types of cancer, it is now considered too toxic for use^[6]^[7]^[8]^[9]
