According to Xinhua News Agency, American researchers found that the eight chemicals contained in essential oils such as lavender and tea tree may interfere with human hormone secretion and may be related to abnormal development of breast tissue in adolescent boys.
Lavender and tea tree oils consist of hundreds of chemicals. Researchers at the National Institute of Environmental Health Sciences in the United States examined eight key components and allowed them to act on human cancer cells in the laboratory to observe possible changes. They found that all eight chemicals activated estrogen to varying degrees and inhibited testosterone. Of the eight chemical substances, four are common to lavender and tea tree oil, and the other four are found in two essential oils. Some of the chemicals are found in at least 65 other essential oils.
Essential oils extracted from plants are widely found in daily chemicals such as shampoos, lotions, and soaps. Essential oils are also popular cleaning and medical treatment products. The body's response to essential oils varies from person to person. Research leader Ramsay believes that the results of the study show that people should use essential oils with caution. “Our society thinks essential oils are safe,†he said. “However, it contains a variety of chemical components that should be used with caution because some components are potential endocrine disruptors.†The researchers will report this to the ongoing annual meeting of the American Endocrine Society.
