First seen May 28, 2026 · Last updated Jun 16, 2026 · Updated 1 time

Summary

This study looked at how frankincense, lemon, and wild orange essential oils are absorbed into the blood when taken by mouth in different capsule types. Nineteen healthy adults took part, and researchers measured oil levels in the blood over 24 hours. The goal was to see if the capsule type changes how the body processes the oils, and to check for any safety concerns.
