Tulsi Extract (Standardized)
Tulsi extracts are concentrated and standardized to specific marker compounds, such as 2% ursolic acid, allowing consistent botanical composition.

Tulsi Herbal Powder
Tulsi herbal powder is made from dried whole leaves and contains the plant in its natural, un-concentrated form.
Why Standardization Matters
Most scientific studies on Tulsi focus on standardized extracts, not whole-leaf powder.
Standardization allows:
- Measurement of ursolic acid
- Batch-to-batch consistency
- Reliable botanical comparison
Important Reminder
Scientific research studies botanical extracts under controlled conditions.
Retail dietary supplements are not evaluated in the same way.
