Safety, Side Effects and Contraindications

Calendula officinalis can be a beneficial medicinal plant used for its anti-inflammatory, antifungal, and wound-healing properties, but it should be used with caution.

While generally considered safe for short-term use, it may cause side effects such as skin irritation, allergic reactions, or gastrointestinal upset in some individuals. It may interact with certain medications, including blood thinners and immunosuppressants, potentially increasing the risk of bleeding or reducing the effectiveness of these drugs. Special populations, such as pregnant or breastfeeding women, should avoid using calendula due to limited safety data, and individuals with chronic illnesses should consult a healthcare provider before use.

To ensure safe use, it is advisable to use calendula in diluted forms, avoid prolonged topical application, and seek professional guidance when considering internal use or combining it with other treatments.

Growing, Harvesting and Storage

Calendula officinalis grows best in well-drained, fertile soil with a pH between 6.

0 and 7. 5, in full sun to partial shade, and requires regular watering to maintain consistent moisture without becoming waterlogged. It thrives in temperate climates and is relatively easy to cultivate, with regular weeding and thinning of seedlings to promote healthy growth. The best time to harvest calendula is when the flowers are fully open but before they begin to wilt, typically in the morning, using sharp scissors to cut the blooms without damaging the plant. After harvesting, the flowers should be spread out in a single layer on a clean surface to dry in a cool, dark, and well-ventilated area, then stored in airtight containers to preserve their potency and color.

Properly dried and stored calendula retains its medicinal properties for up to a year, making it ideal for use in teas, salves, and other herbal preparations.
