🌿 Dosage and Preparations

Decoction (Traditional Use):

• The traditional method of preparing Pau d'Arco involves using the inner bark of the tree. For this decoction, it is recommended to use approximately 1–2 tablespoons of the inner bark per quart of water. This ratio ensures that the beneficial compounds are adequately extracted during the boiling process.

• To prepare the decoction, begin by bringing the water to a gentle boil. Once boiling, add the inner bark and reduce the heat to a simmer. It is crucial to keep the pot covered during the simmering process, which should last for about 20–30 minutes. This covering helps retain the volatile compounds and essential oils that are beneficial for health.
