It can be prepared as a tea by steeping the seeds in hot water, or as a decoction by simmering them for a longer period, while infusions involve soaking the seeds in oil or alcohol. Topical preparations are also common, such as applying the oil directly to the skin for conditions like eczema or inflammation. The recommended dosage for adults is typically 1-2 grams of seeds per day, while children should only use it under medical supervision if deemed safe.

Safety, Side Effects and Contraindications

Nigella sativa can be a beneficial medicinal plant with various therapeutic properties, but its use requires careful consideration due to potential safety concerns.

While generally considered safe when used in moderate amounts, it may cause gastrointestinal side effects such as nausea, vomiting, and diarrhea, particularly at higher doses. It may also interact with certain medications, including blood thinners and diabetes treatments, potentially enhancing their effects and increasing the risk of adverse reactions. Pregnant and breastfeeding women should avoid nigella sativa due to limited safety data, and individuals with chronic illnesses should consult a healthcare provider before use.

To ensure safe use, it is recommended to follow recommended dosages, consult with a healthcare professional, and discontinue use if any adverse reactions occur.

Growing, Harvesting and Storage

Nigella sativa grows best in well-drained soil with a pH between 6.0 and 7.5, in full sun to partial shade, and requires regular watering during the growing season, though it is somewhat drought-tolerant once established.

It thrives in temperate climates and should be planted in early spring after the last frost, with spacing of about 15-20 cm between plants to allow for proper air circulation and growth. Regular weeding and soil aeration are essential, along with periodic fertilization with a balanced organic fertilizer to promote healthy growth and seed production. Harvesting occurs when the seed pods turn from green to brown and begin to dry, typically in late summer to early autumn; the seeds are collected by shaking the pods into a container or using a gentle tapping method to avoid damaging the seeds.

To preserve potency, the seeds should be thoroughly dried, stored in airtight containers in a cool, dark, and dry place, or refrigerated for longer shelf life.
