Safety, Side Effects and Contraindications

While generally well-tolerated, some people may experience gastrointestinal discomfort, such as nausea or bloating, and allergic reactions in sensitive individuals.

Growing, Harvesting and Storage

Ocimum tenuiflorum grows best in well-drained soil that is rich in organic matter, with a pH range of 6.0 to 7.5, and requires full sun exposure for optimal growth and essential oil production. It thrives in warm climates with regular watering, but it should be watered deeply but infrequently to avoid waterlogging and root rot. Regular pruning and fertilization with a balanced organic fertilizer every 4-6 weeks help maintain plant vigor and promote continuous growth. Harvesting is most effective during the early morning or late afternoon, when essential oils are most concentrated, using sharp scissors to cut the top 10-15 cm of the plant, ensuring the leaves remain intact. After harvesting, the plant material should be dried in a shady, well-ventilated area to retain potency, then stored in airtight containers in a cool, dark place or refrigerated to preserve its medicinal properties for extended use.
