*Internal use of lemon oil carries very *significant risks*, and some steps must be strictly followed. Undiluted ingestion has caused serious chemical burns to mucous membranes and liver toxicity. The only oils that should be used are food-grade oils, and even then, they must be extensively diluted.

Through distillation, we extract concentrated compounds that our bodies cannot safely metabolize. For example, I have witnessed clients who become nauseous and have an inflamed esophagus from too much undiluted oil....... When trying to obtain health benefits, inhalation can provide comparable benefits without the risk of ingestion. Diffusing is always the preferred method for using essential oils over ingestion.

Oil Selection

  • Exclusively use oils labeled 'food-grade' for culinary purposes
  • Verify third-party testing certifications for purity
  • Never consume aromatherapy-grade oils internally

Proper Dilution

  • Maximum 1-2 drops per 8oz (240ml) of liquid
  • Always dilute in fatty carriers like honey or milk
  • Never exceed recommended concentrations

Risk Mitigation

  • Consult doctor before use during pregnancy/medications
  • Discontinue immediately if discomfort occurs
  • Keep oils away from children's reach

Aromatic substitutes provide similar benefits safely. Diffusing lemon oil can reduce anxiety and enhance concentration without the need for consumption. For digestive support, inhaling the essence before meals can increase bile production. I recommend this option over internal use. It works the same and is completely safe.

Professional guidance is key to considering internal use. Certified aromatherapists will provide protocols to follow. Under no circumstances should you self-prescribe essential oils internally. With the right precautions, food-grade essential oils do have limited applications. Overall, inhalation is the smartest option for daily wellness use.
