Chemical Composition and Nutritional Profile

Black Nightshade contains a variety of bioactive compounds, including alkaloids such as solanine and scopolamine, which have potent pharmacological effects, as well as flavonoids like quercetin and kaempferol, which contribute to its antioxidant properties.

To ensure safety, it is recommended to use solanum nigrum only under medical supervision, follow recommended dosages, and discontinue use if adverse reactions occur.

Growing, Harvesting and Storage

Solanum nigrum grows best in well-drained, loamy soil with a slightly acidic to neutral pH, in full sun to partial shade, and requires regular watering to maintain consistent moisture without waterlogging.

It thrives in temperate climates and should be planted in spring after the last frost, with spacing of about 30-60 cm between plants to allow for air circulation and growth. Regular care includes mulching to retain soil moisture, pruning to encourage bushier growth, and monitoring for pests like aphids and spider mites. Harvesting should occur when the berries are fully dark purple and firm, typically in late summer to early autumn, using clean hands or gloves to avoid contamination.

To preserve potency, the harvested berries should be dried in a cool, dark place with good airflow, then stored in airtight containers in a cool, dry location or refrigerated to maintain their medicinal properties.
