Clinical evidence
Human clinical trials specifically investigating the oral consumption of Usheera extracts for internal medical conditions are limited. Most modern research focuses on the essential oil's topical or aromatherapy applications, or relies on in vitro and animal studies to elucidate its mechanisms. Some small human studies suggest that vetiver essential oil, when inhaled, may have calming, anxiolytic (anxiety-reducing), and neuroprotective effects, potentially improving alertness and reducing mental fatigue. However, these are often small-scale studies and not directly related to internal consumption for specific diseases. Rigorous, large-scale human clinical trials investigating specific health conditions are needed to validate traditional claims and establish dosages and efficacy for internal use.
