Kora Dębu Krakowskie Zakłady Zielarskie „herbapol” W Krakowie (Quercus Cortex)

The bark of the oak tree contains tannins, flavonoids, and phenolic acids. Tannins create a protective astringent layer on mucosal surfaces, reducing secretions and inflammation. Flavonoids inhibit cyclo‑oxygenase enzymes, limiting prostaglandin production, while antioxidant compounds neutralise free radicals, collectively providing anti‑inflammatory effects.

The appropriate dose of Quercus Cortex is determined by the prescribing healthcare professional based on the specific formulation, route of administration, and individual patient factors. Patients should follow the dosage instructions provided by their clinician or the product label.

Safety data for Quercus Cortex in pregnancy and lactation are limited. It is generally advised to avoid use during pregnancy unless a qualified healthcare provider determines that the potential benefits outweigh any risks. Similarly, breastfeeding mothers should consult a professional before using this herbal product.

Compared with other herbal anti‑inflammatories such as turmeric or willow bark, Quercus Cortex offers a high tannin content that provides strong astringent properties, making it particularly useful for mucosal and skin applications. Its flavonoid profile also contributes to anti‑oxidant activity, though the overall efficacy varies with formulation and individual response.

Store the product at ambient temperature, preferably below 25 °C, in its original packaging. Protect it from moisture, direct sunlight, and extreme temperature fluctuations to maintain stability. Keep the container tightly closed when not in use.

Quercus Cortex can be administered orally as a tincture or capsule, applied topically to the skin, or used as an oromucosal rinse, depending on the specific product formulation. The route of administration should follow the prescribing clinician’s instructions and the product’s labeling.

The most serious risks include severe allergic reactions such as anaphylaxis, potential liver injury, kidney impairment, and rare blood disorders like thrombocytopenia. Patients experiencing signs of these conditions should discontinue use and seek immediate medical attention.

Individuals with known hypersensitivity to oak bark or related botanical extracts should avoid Quercus Cortex. It is also contraindicated in patients with severe liver disease, those on anticoagulant therapy without close monitoring, pregnant or breastfeeding women unless advised by a healthcare professional, and children unless specifically prescribed.
