Government health authorities have issued warnings, such as Western Australia's Department of Health highlighting that even 2 mL of eucalyptus oil can be highly toxic to infants^{[3]Source: Western Australia's Department of Health, "Essential oils – Health warning", www.healthywa.wa.gov.au}. Similarly, the Royal Children's Hospital has introduced clinical practice guidelines for managing essential oil poisoning. Johns Hopkins Medicine, in its pediatric safety guidance, advises against using peppermint for children under 30 months due to seizure risks and recommends strict dilution protocols: 0.25-0.5% for infants and 2.5-5% for adults. These complexities discourage casual use. The stringent safety requirements necessitate comprehensive consumer education, compliance with product labeling standards, and careful consideration of liability risks. This increases market entry costs and restricts promotional messaging, further compounded by social media platforms' limitations on health claims for essential oil products.

Regulatory limits on indoor VOC emissions

Governments are increasingly addressing the impact of indoor air quality on public health, leading to stricter regulations on volatile organic compounds (VOCs), which significantly affect the formulation and marketing of aromatherapy products. The EPA's National VOC Emission Standards for Consumer Products impose content limits on air fresheners, such as 3% for solids and up to 70% for single-phase aerosols. Fragrances, however, are exempt from VOC calculations if used up to 2% by weight. The University of San Francisco identifies air fresheners as major VOC sources, which can cause issues like eye irritation, headaches, and allergic reactions. They recommend using low-emitting alternatives and reducing fragrance levels. According to the EPA's technical overview, indoor VOC concentrations are often 2-5 times higher than outdoor levels. Essential oil diffusion can further increase indoor exposure, potentially forming harmful byproducts when interacting with ozone. These regulations result in compliance costs, restrict marketing claims, and may limit usage recommendations. Additionally, building codes and workplace safety standards could restrict commercial aromatherapy applications in sensitive environments, such as schools and healthcare facilities.
