500 mg of the leaf extract taken twice daily appears to be recommended for neurological and adaptogenic effects of holy Basil, whereas the only evidence on other health effects or testosterone boosting are done in rats with the dosages of 100-200 mg/kg and 500 mg/kg respectively. This leads to an estimated human dose of:
- • 1,100-2,200 mg for a 150 lb person for general health and 5,500 mg for testosterone boosting
- • 1,500-2,900 mg for a 200 lb person for general health and 7,300 mg for testosterone boosting
- • 1,800-3,600 mg for a 250 lb person for general health and 9,100 mg for testosterone boosting
These are estimated human dosages based on animal research, and it is unsure if they are the optimal doses for humans. *
The safe and effective dose of any type of medication varies, depending on a person’s age, weight, health condition. and other factors. A safe long-term dose of holy basil (tulsi) has not been well established in medical research studies. But a range of dosages was used in short-term studies, these include:

300 mg per day of holy basil leaf extract can be given (for 30 days) for central nervous system disorders.
