What Is Pau-Tenente (Guatteria australis)?
Pau-tenente is a medium-sized tree from the Annonaceae family, the same botanical family as soursop (Annona muricata). In traditional Brazilian herbalism, the bark, leaves, and roots are used medicinally — with the bark being the most valued part due to its higher concentration of active compounds.

Main Benefits of Pau-Tenente Tea
1. Supports Liver Health
Pau-tenente is widely recognized as a natural hepatoprotective plant, meaning it may help protect liver cells from damage caused by toxins, medications, or poor dietary habits. Traditionally, it has been used as supportive care in cases of fatty liver (hepatic steatosis) and mild liver inflammation.
⚠️ Pau-tenente tea should never replace medical treatment for liver disease.
2. Improves Digestion
The bitter compounds present in pau-tenente bark stimulate:
- Bile production
- Digestive enzymes
- Gastric secretions
This makes the tea especially useful after heavy meals or for individuals who experience frequent indigestion, bloating, or sluggish digestion.
3. Helps Relieve Constipation
Pau-tenente tea has a mild laxative effect, helping regulate bowel movements without causing harsh intestinal irritation. It is commonly used as a gentle, short-term option for constipation.
4. Anti-Inflammatory Properties
Research and traditional use suggest that compounds found in pau-tenente may help reduce low-grade inflammation, making it potentially beneficial for:
- Mild joint discomfort
- Inflammatory digestive conditions
- Gastric irritation
5. Mild Diuretic Action
Pau-tenente also acts as a natural diuretic, supporting the elimination of excess fluids and metabolic waste. This may help reduce water retention and support kidney and circulatory health.
Active Compounds in Pau-Tenente
The bark of Guatteria australis contains several bioactive substances, including:
- Alkaloids
- Triterpenes
- Flavonoids
- Phenolic compounds
- Tannins
These compounds are responsible for the plant’s digestive, liver-supporting, and anti-inflammatory effects.
