6 Astringent Infusions for Diarrhea
The use of astringent infusions as a complement to calm diarrhea continues to be used. Even though it’s important to establish the cause of this problem in order to manage it properly, some plants help to accelerate the recovery process.
In particular, they’re useful to treat fluid and mineral loss, regulate secretions and promote good intestinal function. This is largely due to their contribution of phenolic compounds, tannins, and antimicrobial substances that contribute to the balance of the digestive function.

How do astringent infusions work to soothe diarrhea?
First of all, we need to know how astringent infusions work to relieve diarrhea. An astringent refers to a substance capable of toning or tightening tissue. In this particular case, plant compounds reduce irritation in the intestinal tissue, toning it and providing a protective effect against pathogens.
In turn, they slow bowel movements and decrease the frequency and volume of bowel movements. In this regard, an article published in Pharmacognosy Magazine explains that polyphenols – and especially tannins – are mainly responsible for the astringency of herbs. Thus, it’s advisable to choose ones with an abundant supply of these substances.
The role of tannins in the management of diarrhea
Tannins are water-soluble phenolic compounds characterized by their astringent, anti-inflammatory, and antioxidant action. As detailed in a publication in Biomolecules, their main function is to protect plants against insect and fungal attack.
In addition, it’s the component that produces that bitter taste and that rough, dry sensation when tasting certain fruits and herbs. As far as medicinal effects are concerned, they’re known for their action against diarrhea. As they have the ability to dry and deflate mucous secretions, bowel movements tend to be reduced.
For this reason, they’re now used in the manufacture of anti-diarrhea supplements. A study shared through the Revista Española De Enfermedades Digestivas reported that gelatin tannate – a tannin-based supplement – helped reduce the consistency and number of stools in children with acute diarrhea.

1. Blackberry leaves or roots
The blackberry, whose scientific name is Rubus fruticosus, is a plant known for its abundant content of tannins, gallic acid, vitamin C, pectin, and iron. A publication reported through Pharmacognosy Reviews details that its roots, in particular, have been used as an adjuvant against diarrhea.
In addition, through the journal Molecules, it was reported that the root bark and leaves of this plant have astringent potential, which gives it antidiarrheal properties.

2. Blueberry leaves
A study shared via Frontiers in Pharmacology details that both the leaves and fruits of blueberries (V. myrtillus) are abundant in tannins. In fact, the entire Vaccinium genus is recognized for this quality.
It’s estimated that up to 10% of the leaves contain this substance. Hence its astringent and antidiarrheal properties.
