Pau d’Arco – Bark Extract (Tabebuia impetiginosa)

Hawaii Pharm's Pau d’Arco bark (Tabebuia impetiginosa) is sourced from selected suppliers based on the quality and storage conditions of their botanical raw materials. Particular attention is given to botanical identification, bark quality and suitability for use in liquid extract preparation.

Botanical Identification and Quality Control

To verify raw material identity and support consistent quality, Hawaii Pharm states that it conducts analytical testing in its laboratory.

The methods mentioned include:

• HPTLC (High-Performance Thin-Layer Chromatography): used for botanical identification and the development of a characteristic chromatographic fingerprint of the plant material.

• FTIR (Fourier Transform Infrared Spectroscopy): used to examine the spectral characteristics of raw materials.

Additional in-house analytical methods may complement these tests, depending on the applicable specifications.

Quality Standards and References

Depending on the analyses performed, the quality-control procedures refer to technical standards and publications such as those of the USP (United States Pharmacopeia) and the European Pharmacopoeia (Ph. Eur.).

The manufacturer also refers to ISO/IEC 17025 and cGLP frameworks as part of its quality approach.

These controls are intended to document botanical identity and assess whether raw materials meet defined quality and purity specifications.
