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 isn't a same-day anxiolytic (calms anxiety).

Can I take tulsi with metformin (a common diabetes medicine)?

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.

Holy Basil (Tulsi)

The Essentials

A living tulsi plant in a clay pot, upright stems crowded with small oval green leaves and purple-tinged shoots — Holy basil (tulsi) grows as a small bushy plant — soft oval leaves on square stems, kept potted by the door in many households.

Supports stress resilience and steady daytime mood in RCTs of 500–1200 mg leaf extract per day.

Modest fasting-glucose and post-prandial-glucose lowering: helpful adjunct with monitoring in type 2 diabetes.

Traditional respiratory support — warm tea for winter cough, damp chest, and mild seasonal congestion.
