Allergy information
Holy Basil (Ocimum tenuiflorum) may cause mild allergic reactions in sensitive individuals, especially those allergic to plants in the mint family. The main triggers are its pollen and contact with its leaves or sap. Symptoms can include skin irritation or respiratory discomfort. To reduce exposure, avoid direct contact if you have sensitive skin and keep the plant away from areas where pollen can accumulate indoors.
Common problems
Overwatering can cause root rot, and low light may lead to leggy, weak growth. Pests such as aphids or whiteflies can occasionally appear. Lack of pruning may result in a less bushy plant.

Notes
Prune regularly to prevent flowering if you want to prolong leaf production. Repot annually or when root-bound. Protect from frost and cold drafts.
