If you are looking for a therapeutic-grade thyme essential oil I recommend Young Living. Here is a link to a couple of posts I did on Young Living's thyme:
This information only applies to Young Living's thyme essenial oil.
If you want a therapuetic-grade essential oil a couple of ways to determine if an oil will have therapuetic benefits or if it is only good for its aroma.
1. If it is therapeutic-grade it WILL say so on the label.
2. If it is therapeutic-grade it WILL say it can be taken internally (orally) and applied topically.
3. If it is therapeutic-grade it WILL say it is a dietary supplement on the label.
I hope you find this information helpful.
Most essential oils are of a perfume or aroma-grade and do not have therapeutic value.
Young Living only produces and sells therapeutic-grade essential oils.
