Tulsi, another name for Holy Basil, is an adaptogenic herb central to Ayurvedic tradition. People use it to help the body handle stress and maintain a sense of calm and balance. Capsules, tinctures, and teas are common forms, usually taken with food or as directed on the label.
Holy Basil can influence blood sugar and blood pressure levels. Anyone on medications related to those areas should talk to a healthcare professional before use. Long-term, high-dose use is not recommended without guidance from a qualified practitioner.
