What is Potentilla Extract used for?

Potentilla Extract is traditionally used as an astringent herb for acute diarrhea and for soothing inflamed tissues, especially in the gastrointestinal tract and mouth. It is commonly sourced from Potentilla erecta (tormentil) or related species.

How does Potentilla Extract help with diarrhea?

It is rich in tannins, which have astringent effects that can reduce intestinal secretions and help firm stools. Some clinical and preclinical evidence supports its use for acute nonspecific diarrhea.

What is a typical dosage range for Potentilla Extract?

Common supplemental amounts fall around 200–1500 mg per day, depending on extract strength and product directions. Follow label instructions and consider medical advice for children, pregnancy, or persistent symptoms.

Is Potentilla Extract safe, and who should avoid it?

It is generally used short-term, but tannin-rich extracts may cause stomach upset in some people. Avoid or seek medical guidance if you are pregnant or breastfeeding, have chronic gastrointestinal disease, or if diarrhea is severe, bloody, or prolonged.

Does Potentilla Extract have anti-inflammatory or antioxidant effects?

Preclinical research suggests Potentilla extracts can modulate inflammatory pathways and provide antioxidant activity due to polyphenols and flavonoids. These effects are supportive but do not replace medical treatment for inflammatory conditions.
