Pau D'Arco: what we published in August 2023

August's highlight is a focused piece on Pau D'Arco, the South American tree bark that's popping up in supplements worldwide. The article explains what people are taking it for, what the lab research shows, common ways to use it, and practical safety notes you should know before trying it.

What is Pau D'Arco?

Pau D'Arco comes from the inner bark of Tabebuia trees native to South America. People use it as a herbal supplement for inflammation, mild infections, and general immune support. The two compounds most often mentioned are lapachol and beta-lapachone — lab research ties these to antimicrobial and anti-inflammatory activity in test-tube and animal studies. That doesn’t automatically mean the same results happen in people, but it helps explain why the herb is popular.

How people use it and safety tips

Most users take Pau D'Arco as a tea, capsule, or tincture. Typical over-the-counter capsules range from about 250 mg to 1000 mg; many people start low (one 250–500 mg dose) and watch how they feel. Tea is brewed from the bark and tends to be milder, while tinctures deliver a stronger, easier-to-measure dose.

There are real safety points to keep in mind. Lapachol can affect blood clotting and may interact with blood thinners. Some people report stomach upset, nausea, or dizziness. Pregnant or breastfeeding people should avoid Pau D'Arco due to limited safety data. If you take prescription meds — especially anticoagulants or immunosuppressants — check with a clinician before starting it.

We also touch on quality: supplements vary. Look for products from brands that list batch testing, clear ingredient sources, and straightforward dosing. Avoid mixes that hide Pau D'Arco under long herbal blends if you want a predictable effect. If the label lists lapachol content, that can help you compare products.

Research-wise, the August post is clear: there are promising lab results but limited strong clinical trials in humans. That’s why the tone of our write-up stays practical — you can try it for mild uses, but don't expect miracle cures. Anyone with serious health issues should prioritize proven medical treatments and use Pau D'Arco only after discussing it with a healthcare provider.

Quick practical tips from the article: start with a low dose, track any side effects for a week, pause before surgeries, and keep your healthcare team in the loop. If you want the full breakdown, the original post covers preparation methods, personal reports, and how to read supplement labels.
