Scientific Research 

According to scientific research data and publications of the European Food Safety Authority (EFSA), tannic substances (tannins) contained in oak bark have the ability to bind proteins to form a protective film on mucous membranes:

1. Astringent action and protection of mucous membranes: according to scientific evaluations by the European Food Safety Authority (EFSA Journal / Botanical Assessments), high-molecular-weight tannins form albuminates — dense protein complexes on the surface of mucous membranes and skin. This creates a mechanical protective barrier that reduces irritation, prevents pathogen penetration, and supports natural tissue barrier function.
2. Official EMA monograph and anti-inflammatory potential: as stated in the scientific monograph of the Committee on Herbal Medicinal Products of the European Medicines Agency (EMA / HMPC), oak bark decoctions are a proven traditional remedy for the symptomatic treatment of oropharyngeal inflammatory conditions (gingivitis, stomatitis), as well as for relieving mild diarrhea and local skin irritations.
3. Antibacterial and antioxidant activity: studies in the international database PubMed regarding the pharmacological profile of Quercus robur confirm that condensed tannins (proanthocyanidins) and ellagitannins inhibit the growth of Gram-positive and Gram-negative bacteria, neutralize free radicals, and accelerate the regeneration of damaged epithelial tissues.
