A teacher wrote in and asked about using aromatherapy in school with children in class, to aid learning, lessen stress, and in tests and exam situations, which essential oils work best and which blends.

Here are my recommendations for using aromatherapy in learning and remembering for children; and also an additional article on which essential oils to use for mature students to improve studying, learning, memory and recall of the studied materials for tests and exams, and even, later on in life should they ever need to remember beyond the exam.

Essential oils produced from organically grown plants are much more expensive than those produced from generally farmed plants.

In this product test I'm comparing Bergamot essential oil in both version to discover whether the higher price for organic essential oils is worth it - or not.

Pennyroyal is much maligned as being oh so dangerous – this is the same old story again about all the essential oils. It is no more dangerous than aspirin, which is sold freely over the counter, and in aroma energy work, we don’t take it internally nor do we even put it on our skin so that’s triply safe then.

With that out of the way, Pennyroyal, a member of the mint family, has some exquisite and extraordinarily useful energetic effects and actions.

I started to search the three – Salvia Lavendulifolia, Spanish Sage; Salvia Officinalis, Wild Sage; and Salvia Triloba, also known as Sage Triloba.

As soon as I put in the word “Salvia”, the search engine exploded with references to Salvia Divinorum, of which, I admit, I hadn’t heard a thing.

It is actually quite difficult to compare prices amongst aromatherapy essential oils. A bottle of Valerian might cost ten pounds, or twenty - but read the small print and there may be only 5ml in a 10ml bottle, or 3ml in a 5ml bottle.

But what is a milliliter when it is at home? How many drops are in a milliliter? I've calculated a price "penny per drop" for some of the most popular aromatherapy essential oils to give us a bit of a guideline in this minefield of sizing and pricing.

Artemisia Absinthium and Artemisia Afra essential oils are very powerful energetic devices that can do a lot for you in aroma energy work.

But it might be you've never heard of them ...?

A study at the Medical University of Vienna finds that the two aromatherapy essential oils they studied, Orange and Lavender, reduce anxiety.

There are two other aromatherapy oils I often recommend for reducing anxiety, one works particularly well with reducing anxiety in children.

An interesting story I came across the other day was a reference that using Helichrysum essential oil was particularly good for “repairing the holes in the aura caused by tattoos”.

Here are some thoughts on the topic and an easy technique to use Helichrysum (or any other essential oil of your choosing) to heal injured ereas and thus, close up the holes in the aura.
