How to Brew Pau d'Arco Tea Correctly
Important disclaimer
This article is for educational purposes only and is not medical advice. These statements have not been evaluated by the Food and Drug Administration. Pau d'Arco is not intended to diagnose, treat, cure, or prevent any disease. We summarize published research and traditional use — this is not a recommendation to use Pau d'Arco for any specific condition. Always consult a qualified healthcare professional before starting a new supplement, especially alongside an existing medical condition or medication.
If you've started exploring Pau d'Arco (also called Taheebo), you've probably seen it described as a powerful bark from the Amazon. Here's the catch: many people treat it like a regular herbal tea — steeping it in hot water for a few minutes — and miss most of what makes it worth brewing correctly in the first place.
Why the Decoction Method Matters
The naphthoquinones in Pau d'Arco — lapachol and beta-lapachone — are not very water-soluble at lower temperatures. Extraction research indicates these compounds require sustained heat to break down the bark's cellular structure and release into the water. A quick steep leaves most of these compounds in the bark, not in your cup.

Choosing the Right Bark
- Use the inner bark — the phloem, where the studied compounds concentrate. Many cheaper products use whole bark or wood filler. See our inner bark guide.
- Confirm the species — look for Handroanthus impetiginosus (Tabebuia avellanedae), the most-studied variety.
- Fine grind vs. coarse cut — fine grind yields a stronger tea (more surface area) but needs a finer mesh filter.
How to Brew Pau d'Arco, Step by Step
Ingredients and equipment:
- 3 tablespoons of pure Pau d'Arco inner bark
- 4.5 cups of filtered water (distilled or spring water preferred)
- A glass or stainless steel pot (avoid aluminum — it can react with the bark's compounds)
- A fine mesh strainer or cheesecloth
The process:
- Mix — add the bark and water to your pot.
- Boil — bring to a rolling boil over high heat.
- Simmer — reduce heat to low, cover with a tight-fitting lid.
- Wait — simmer gently for 25–30 minutes. The water will turn a deep reddish-amber.
- Cool and strain — remove from heat, let sit briefly, then strain through your fine mesh into a glass jar or pitcher.
What a Proper Brew Provides
Lab research reports antimicrobial and antifungal activity in Pau d'Arco extracts, which is the basis for its traditional use in gut and Candida support. Traditional and preliminary research also point to antioxidant and anti-inflammatory activity, relevant to general inflammation. None of this is a clinical treatment claim — see each linked article for the specific evidence tier.

Dosage and Storage
For general wellness, 1–2 cups daily is a common traditional-use starting point; for a specific concern, some traditional-use sources suggest up to 3 cups, starting slow.
Storage: refrigerate brewed tea in a sealed glass jar. It stays fresh for about 48 hours — its natural antimicrobial properties help it resist spoiling somewhat better than typical herbal teas, but a fresh batch every two days is best for taste and potency.
Precautions and Considerations
- Pregnancy: avoid — some studies indicate isolated lapachol may have abortifacient properties.
- Nausea: very high doses can cause GI upset; reduce your dose if this happens.
- Blood thinners: consult your doctor if you're on blood-thinning medication.

Where This Leaves Us
Brewing Pau d'Arco correctly takes a bit more time than a tea bag, but it's the difference between flavored water and a decoction that actually contains the compounds this site's research is about. We use this same method for Taheebo Wellness Tea.
