Historical Background

Tulsi ('the incomparable one') has been revered in Hindu tradition for thousands of years as a sacred plant of the goddess Lakshmi and a household protector. In Ayurveda it is a rasayana (rejuvenative) for the lungs, mind, and immunity, and daily tulsi tea is a widespread devotional and wellness practice.

Earliest recorded uses: Vedic and Ayurvedic texts; Charaka Samhita classifies tulsi among revered plants.

Cultural significance: Tulsi is grown in courtyards across India and worshipped daily; its name means 'the incomparable one.' Few herbs carry such deep living religious significance, bridging kitchen, temple, and clinic.

Tea Information

Research Summary

Tulsi has a long Ayurvedic tradition as an adaptogen and respiratory herb. A number of small human trials suggest modest effects on stress markers and metabolic parameters, but evidence is limited and studies are small and heterogeneous. It is not a treatment for any disease.

Evidence levels reflect the currently available scientific literature and may change as new research emerges. Where evidence is limited or conflicting, this is stated plainly.
