About TABEBUIA AVELLANEDAE BARK POWDER
A traditional astringent bark from the pink trumpet tree — used in South American folk medicine for skin repair, though it contains naphthoquinones that require careful formulation.
Detailed Analysis
Tabebuia avellanedae (Lapacho, pink trumpet tree) bark contains naphthoquinones including lapachol and anthraquinones such as ellagic acid derivatives. These compounds have documented antimicrobial and anti-inflammatory activity in vitro. Lapachol in particular has been studied for its pharmacological effects, but the same quinone chemistry that drives bioactivity also raises concerns around photosensitization and long-term use at high doses. Use in cosmetic formulations is permitted but warrants moderate caution.
