Safety, Side Effects and Contraindications

Crithmum maritimum can be used as a medicinal plant with some therapeutic benefits, but it must be approached with caution due to its potential safety concerns.

While generally considered safe when used in moderate amounts, it may cause gastrointestinal upset, including nausea, vomiting, and diarrhea, especially in higher doses. There is limited research on its interactions with other drugs or herbs, but it is advisable to avoid combining it with anticoagulants or antiplatelet agents due to the risk of increased bleeding. Special populations, such as pregnant or breastfeeding women, should avoid using crithmum maritimum due to insufficient evidence on its safety during these periods, and individuals with chronic illnesses should consult a healthcare provider before use.

To ensure safe use, always consult a qualified healthcare professional before starting any regimen involving crithmum maritimum, and follow recommended dosages to minimize adverse effects.

Growing, Harvesting and Storage

Crithmum maritimum grows in coastal regions with well-drained, sandy or gravelly soils that are slightly alkaline, preferring full sun to partial shade.

It thrives in maritime climates with moderate rainfall and requires minimal water once established, making it drought-tolerant. Regular weeding and occasional light pruning can help maintain its vigor, while avoiding overwatering to prevent root rot. The plant is typically harvested in late summer to early autumn when the leaves are fully developed and the essential oils are most concentrated, using shears to cut the foliage at the base.

For optimal potency, the harvested material should be dried in a shaded, well-ventilated area, then stored in airtight containers in a cool, dark place to preserve its medicinal properties.
