Chemistry equals efficacy and safety. Four essential oils that are known to vary in chemistry are oregano, thyme, sage, and rosemary. A recent study evaluated these four oils in various laboratory tests to determine their bioactivity. Oregano CT carvacrol and thyme CT thymol were the most active antioxidants and antimicrobials. Each essential oil demonstrated excellent anti-inflammatory activity, with rosemary CT verbenone exceeding the activity of dexamethasone (a steroid anti-inflammatory).

E. coli is gram-negative bacteria, that certain strains of it can cause serious food poisoning. It can also infect the urinary tract--it is the most common cause of urinary tract infections--and other areas of the body. A laboratory study concluded that coriander essential oil was more effective than ciprofloxacin against E. coli, suggesting that it is a promising natural solution for UTIs and food poisoning.

A clinical study explored the calming effects of bitter orange (Citrus aurantium) inhalation on psychological distress, pulse, and blood pressure in first-year nursing students—a group known to experience high levels of stress during academic transition. Using a one-group pretest-posttest quasi-experimental design, 74 students inhaled the scent of fresh bitter orange peel for five minutes (a simple way to inhale its aromatic compounds). Psychological distress was measured using the Kessler Psychological Distress Scale, while pulse and blood pressure were recorded before and after the intervention. Results revealed a statistically significant reduction in distress, along with favorable changes in physiological indicators: systolic and diastolic blood pressure decreased, and pulse slightly increased, possibly due to momentary stimulation. These findings affirm that aromatherapy from bitter orange peel—rich in the calming compound d-limonene—can serve as a gentle, non-pharmacological tool for promoting emotional balance and cardiovascular harmony in stressed populations.

A preclinical wound model found that mace (Myristica fragrans pericarp) EO significantly reduced pro-inflammatory cytokines (IL-1β and TNF-α), the expression of CD68 (a valuable marker that reflects the progression and quality of wound healing), and limited damage caused by oxidative stress (reduced ROS and MDA levels while restoring GSH and SOD activity). The findings of this study demonstrate the mace EO promotes wound healing by regulating inflammation, oxidative stress, and skin cell death.

Inhalation of essential oils can be powerful because the aromatic compounds directly interact with the nervous system and subsequently trigger positive endocrine and other biological effects. Inhalation of bitter orange (Citrus aurantium peel) EO significantly reduced body fat percentage, liver fat accumulation, and blood cholesterol and triglyceride levels in a preclinical model. Further analysis of its mechanism confirmed that the EO adjusted gene expression related to lipid metabolism and cholesterol synthesis, including Ucp1, Hmgcs1, and Hmgcr.

Evaluation of patches with lavender essential oil and ibuprofen showed that lavender essential oil significantly increased the release and permeation of ibuprofen through the skin (2-fold) when compared to a patch with only ibuprofen. In addition, the lavender patch released the ibuprofen more quickly showing a more rapid therapeutic effect. This suggests that a pain patch with lavender and other pain-relieving actives has promise for pain management.

Given the risks associated with statins, both scientists and the public are searching for alternatives to support healthy cholesterol levels. A clinical study reported that ingesting capsules containing 140 mg (about 3 drops) of lemongrass essential oil improved cholesterol profiles in 36% of trial participants. The researchers hypothesized that the decrease was the result of the oil suppressing an enzymatic pathway involved in cholesterol creation.

Exercise causes metabolic alterations such as the release of pro-inflammatory cytokines, increased oxidative stress, and the accumulation of metabolites, which leads to muscle fatigue or soreness. Previous research showed that peppermint essential oil limits these metabolic alterations to improve exercise performance. Repeated inhalation of peppermint essential oil (16 mcL/hour for two weeks) significantly delayed time to exhaustion in exercise-trained subjects. Interestingly, subjects exposed to the same levels of peppermint that did not exercise regularly did not receive the same benefits, suggesting that the activity of peppermint is not primarily ergogenic but rather reinforces the effects of exercise training to increase physical performance.

A microemulsion containing lemongrass (C. flexuosus) EO was investigated in diabetic subjects to determine if it could reduce oxidative stress. High blood sugar can lead to damage from oxidative stress. The microemulsion enhanced the antioxidant activity of the EO. Oral administration of the free EO or its microemulsion for 21 days decreased blood sugar levels and improved lipid (cholesterol and triglycerides) profiles. However, the microemulsion also reduced liver damage, improved kidney function, and decreased inflammation related to diabetes. Overall, this research suggests that lemongrass in a microemulsion is a promising candidate for further human research to manage diabetes and its adverse effects.

I find fennel essential oil particularly useful for digestive issues and female reproductive concerns. A recent laboratory study showed that it has good antioxidant, antibacterial, and antifungal activity.
