Bests & Worsts Reviews from Amazon

These scents are all wonderful. And they are all strong enough that if you sniff them out of the bottle they may singe your nose haha. My favorite is probably sweet orange, but they all have useful medicinal purposes. If anyone in my house gets a head or chest cold I am sure the eucalyptus will be used. The peppermint seems to have a positive impact on my sinuses. I actually just used some of the tea tree oil for a hair and skin care recipe using olive oil and essential oils. It worked out very well, especially for my skin. I tend to have very dry, irritated skin in the winter time, and lotions just don't seem to help for very long. I started using olive oil and then thought, why not try adding the essential oils in the recipe? You can tell the difference between just using olive oil versus using olive oil mixed with this tea tree oil. Therefore, while the olive oil works great, the tea tree oil from this sampler definitely adds to the positive effect it has on my skin. My sister plans on using these oils for making homemade soaps. If she gets around to this anytime soon I will try to remember to update this review and let everyone know how well it worked with these oils. Update 1/20/14 I recently started doing some research on essential oils to assuage my own curiosity and I feel I should share it with anyone thinking of purchasing them (which I assume you are if you are reading this). First and foremost, the grading systems companies use to grade their products are all relative because there is no regulation of the grades. So when it says "therapeutic grade", that just means it's that companies idea of therapeutic grade. That's not to say they are misrepresenting their products, but there will be variance between products because there is no standard, so finding a brand you trust is important. Second, don't assume you can use an essential oil for flavoring anything you're going to eat unless it's either food grade (usually labeled and more diluted to prevent injury), has been inspected by the FDA (these will have a nutrition label somewhere), or you know the oils are 100% pure with no additives and you know how to appropriately dilute them to make them edible. If there is no FDA label, there is a good chance that the oil is not 100% what it says it is - it most likely has some additives that are probably best not to consume. For these oils in particular, I personally would not consume them, despite the fact that the labels say they are 100% "insert oil here". The fact that the label specifically says "for external use only" helps that decision :P I lowered my rating of these oils from 5 stars to 4 simply because they are not as pure as I thought they were going to be. Still perfectly usable for their scents, but I think next time I will look for some essential oils that I can be sure are pure (I see more research in my near future... *sobs*). These are just the basics that I gleaned from my research, but if you want to do your own I found this site very helpful: [...] I hope that all helps!
