Safety, Side Effects and Contraindications

Fraxinus excelsior can be used as a medicinal plant with caution due to its potential safety concerns, side effects, and interactions.

While it has been traditionally used for its anti-inflammatory and analgesic properties, it may cause gastrointestinal upset, drowsiness, and in some cases, liver toxicity, especially with prolonged use. It is important to note that fraxinus excelsior may interact with certain medications, including anticoagulants and sedatives, potentially increasing the risk of adverse effects. Special populations such as pregnant women, breastfeeding mothers, and individuals with chronic illnesses should avoid its use without medical supervision due to limited safety data.

To ensure safe use, always consult a healthcare professional before using fraxinus excelsior, start with low doses, and monitor for any adverse reactions.

Growing, Harvesting and Storage

Fraxinus excelsior grows best in well-drained, loamy soil that is moderately fertile and slightly acidic to neutral in pH, with full sun to partial shade, and regular watering during dry periods.

It thrives in temperate climates and requires consistent moisture but should not be overwatered, as it is susceptible to root rot. For optimal growth, regular pruning to remove dead or diseased branches and mulching around the base to retain moisture and suppress weeds are recommended. The best time to harvest the bark and leaves is in late spring to early summer when the plant's active compounds are most concentrated; the bark is typically peeled using a sharp knife or peeling tool to avoid damaging the tree.

After harvesting, the material should be dried in a cool, shaded area with good air circulation to preserve potency, then stored in airtight containers away from light and moisture to maintain its medicinal properties.
