Who should avoid using Horst Pappel 50 g or take extra precautions when using it?

Because the product is a concentrated botanical, it is best suited for occasional use rather than daily consumption over long periods. The following groups should seek professional advice before using it: pregnant or breastfeeding individuals, people with known allergies to poplar or related trees, and anyone taking prescription medication that may interact with herbal substances. Children under twelve should only use the product under the guidance of a qualified practitioner. The infusion contains tannins, which can create a mild tightening sensation in the gastrointestinal tract; those with a history of stomach ulcers or excess acidity may notice this effect and should monitor their response. The standard single dose is roughly one teaspoon of buds per 200 ml of water; exceeding this amount does not increase any potential benefit and may lead to digestive discomfort. The recommended maximum frequency is a few times per week, not daily, to avoid over‑consumption of tannins. If you notice any adverse reaction, stop use and seek medical advice. The product is not a substitute for a balanced diet or a varied herbal regimen. Keep the package sealed after each use and store it in a cool, dry place; discard the product if it develops an off‑odor or noticeable discoloration, as this may indicate loss of freshness.
