Study summary

Tulsi and its effects on facilitative cognitive enhancement through lowering levels of stress and anxiety. A randomised placebo-controlled clinical trial.

Read the detailed description

Ocimum Sanctum or Holy Basil, commonly called Tulsi is a traditional Indian herb. It is believed to bring about a facilitative enhancement of cognitive ability and lower stress levels in individuals. Stress and an inability to perform at a required level of cognition can induce anxiety. This study is looking at the effects of daily consuming Tulsi among a group of individuals who work in an environment that demands memory, attention and executive functioning.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

What researchers measure

Primary outcomes

  1. To assess a change in facilitative cognitive function from baseline in 6 weeks by comparing the results on cognitive tests measured by Cambridge Neuropsychological Test Automated Battery (Cantab®) between active and placebo group

    The Cambridge Neuropsychological Test Automated Battery (CANTAB) is a digital tool to measure the cognitive function.

    Time frame: 6 weeks

Secondary outcomes

  1. To measure change in cortisol level from saliva in 6 weeks

    Salivary levels of cortisol correlates with work related stress levels. Our intention is to evaluate the effect of ocimum sanctum in lowering stress and measured as a change in the cortisol levels

    Time frame: 6 weeks

  2. To measure change in Generalized Anxiety Disorder 7-Item Scale in 6 weeks

    It is a self-reported questionnaire for screening and severity measuring of generalized anxiety disorder (GAD)

    Time frame: 6 weeks

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 17, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
