• Bergamot oil's effectiveness for pain relief is unclear, with promising results in rodent studies but limited evidence in humans.
• Tea tree oil shows significant promise for treating acne, exhibiting antibacterial and antifungal properties and comparable results to benzoyl peroxide with fewer side effects.
• Rosemary oil's alleged memory-enhancing benefits are unsubstantiated by current research, with studies showing no significant improvement in memory.
• Lavender oil appears to be effective in improving sleep quality, with multiple studies indicating positive results through aromatherapy.
