Lapachenol is the allergen of Paratecomba peroba.

ChEBI: Lapachenole is a benzochromene.

Lapachenol is contained in the heart-wood of Lapacho wood (Tabebuia avellanedae Lorentz, Bignoniaceae family). It is a secondary allergen, after lapachol and deoxylapachol, and likely a prohapten transformed in vivo into a quinone hapten.
