Pau D'arco bark supplement review, side effects, clinical trials, health benefit by Ray Sahelian, M.D.

Pau D'arco ( Tabebuia impetiginosa, syn. Tabebuia avellanedae ) is a tree from South America whose inner bark has been used as an analgesic (pain reliever), anti-inflammatory, anti-cancer, anti-bacterial, and diuretic. Little research is available in the North American medical literature regarding its medicinal properties. At present it is difficult to make any clinical recommendations with certainty regarding the medicinal properties and uses of this interesting plant.

Pau D' Arco (Tabebuia altissima) is the highest quality inner bark of the Purple Lapacho tree found in Brazil and Northern Argentina. Ever since ancient times, when it was a standard for the medicine men of the Inca Empire, pau d'arco (also known as ipe roxo and taheebo) has been one of the most widely used herbs in South America. Its popularity is attributed to the active constituents, lapachol and beta-lapachone, which have been the subject of numerous scientific studies.

Antioxidant activity and characterization of volatile constituents of Taheebo (Tabebuia impetiginosa Martius ex DC)
J Agric Food Chem 2003.
Volatiles were isolated from the dried inner bark of Tabebuia impetiginosa. The major volatile constituents of pau darco were 4-methoxybenzaldehyde, 4-methoxyphenol, 5-allyl-1,2,3-trimethoxybenzene (elemicin), propenylbenzene (trans-anethole), and 4-methoxybenzyl alcohol. The antioxidant activity of the volatiles was evaluated using two different assays. The extract exhibited a potent inhibitory effect on the formation of conjugated diene hydroperoxides (from methyl linoleate). The extract also inhibited the oxidation of hexanal for 40 days at a level of 5 microg/mL. The antioxidative activity of pau darco volatiles was comparable with that of the well-known antioxidants, alpha-tocopherol, and butylated hydroxytoluene.

Pau D'arco Research studies
Constituents from the bark of Tabebuia impetiginosa.
Phytochemistry. 2004.
The bark of pau darco afforded nineteen glycosides, consisting of four iridoid glycosides, two lignan glycosides, two isocoumarin glycosides, three phenylethanoid glycosides and eight phenolic glycosides. Iridoid glycosides, phenylethanoid glycosides and lignan glycosides had ajugol, osmanthuside H and secoisolariciresinol 4-O-beta-D-glucopyranoside as their structural elements, respectively, whereas the aglycone moieties of the isocoumarin glycosides were considered to be (-)-6-hydroxymellein. Phenolic glycosides had 4-methoxyphenol, 2,4-dimethoxyphenol, 3,4-dimethoxyphenol, 3,4,5-trimethoxyphenol and vanillyl 4-hydroxybenzoate as each aglycone moiety. Additionally, the sugar chains of these isocoumarin glycosides and phenolic glycosides were concluded to be beta-D-apiofuranosyl-(1-->6)-beta-D-glucopyranoside as well as those of osmanthuside H and above phenylethanoid glycosides.
