Is holy basil the same as Italian basil?

No — different species. Holy basil (Ocimum sanctum) is more peppery, clove-like, and used medicinally as a tea. Italian sweet basil (Ocimum basilicum) is a culinary herb; the two are not interchangeable.

How long until tulsi 'works'?

Adaptogen effects build with daily use. Trials on stress and glucose typically report benefit at 6–12 weeks of daily 300–600 mg extract or 2–3 cups tea. It is not a same-day anxiolytic.

Morning or evening tulsi?

Ayurveda favours the morning cup — tulsi is gently uplifting and sattvic. A small evening cup is fine for people who find it calming rather than stimulating.

Can I take tulsi with metformin?

Traditional daily tea is compatible; concentrated extracts add real fasting-glucose lowering to metformin and can drive hypoglycaemia. Home-monitor for the first two weeks and speak with a clinician before starting an extract.
