Bests & Worsts Reviews from Amazon

I'm a fan of NOW Foods essential oils in general. I think they tend to be a fair price for a good, reliable quality product. Over the years, I've had only one "suspect" oil from NOW, and was able to get a quick, satisfactory solution to my problem. Eucalyptus oil is undoubtedly one of the essential oils I use the most, particularly in the winter to help combat colds and congestion. The large, 16 oz container of oil doesn't have a dropper included, which makes sense to me because essential oils degrade plastic (quite rapidly, too!). It takes me a looong time to get through the whole bottle, and I've no doubt that if I kept a dropper lid on the bottle, it'd be rendered useless before the oil was depleted. The mouth of the bottle is large enough for my 1/4 and 1/2 tsp measuring spoons to fit easily, so I use those to keep spills to a minimum when I'm mixing my little blends. As far as usage goes, I'm leery of using most essential oils undiluted on my skin. Almond, avocado or any light vegetable oil works well to carry the eucalyptus for topical use. For aromatherapy I like a blend of about 4 parts Eucalyptus, 2-3 parts Lavender and 1 part Peppermint in a diffuser (or on the stove in a pot with water) during the winter to help with congestion. Some other reviewers have complained about the potency of the oil they received. I've been very satisfied with what I've received, but I suppose perception of scent is somewhat subjective. This oil doesn't have the knock-your-socks-off harshness associated with some eucalyptus-scented products (like Vapor-eze), but I find it more pleasant and no less effective for being less sharp. Finally, if you're looking for ideas and instructions about using essential oils, rarely will you find details on the bottles of oil themselves. There are a lot of safety considerations (for example, asthmatics, pregnant women, and those with sensitive skin should use caution, depending on the oil) and lots of options for personalization in blends. I suggest Dodt's The Essential Oils Book: Creating Personal Blends for Mind & Body for a beginner's guide or The Aromatherapy Bible: The Definitive Guide to Using Essential Oils for more in-depth knowledge.
