As of September 2024, the best brand of tea tree oil is Plant Therapy Tea Tree Oil (the non-organic actually has better numbers than their organic one).
The batch was tested 2024-03-18:
Terpinen-4-ol is 43.74%
1,8-Cineole is 2.86%
To put those numbers in perspective, the Melaleuca Wellness Company (claims it was the first company to bring Tea Tree oil to the US) has a super high priced Tea Tree oil (as in an insane $24 for 5.8mL) that is guaranteed to have greater than 40% terpinen-4-ol and no more than 3% cineole.
Plant Therapy Prices:
- 10ml=$8.49
- 30mL=$15.99
- 100mL=$27.99
What brands did it beat?
- Edens Garden
- Revive
- Simply Earth
PS: This post was written hastily, mostly for me to remember the research that I did before purchasing a bottle today. I don't know much else about what to look for on a gcms report except for what I discussed above. If you know what else makes for a great tea tree oil gcms report, please chime in below. I'd love to learn more!
