Are these oils safe to use on skin?

Most need dilution in a carrier oil before skin contact. Spice oils such as cinnamon leaf, clove bud and cassia are strong irritants and should be used at very low dilution.

Can I use them in a diffuser?

Yes. The citrus, mint, floral and herbal oils work well in a standard ultrasonic diffuser. Add a few drops per 100 ml of water.

How big are the bottles?

Each bottle holds 10 ml, roughly 200 drops. That is enough for several weeks of occasional diffusing per oil.

Is this a good starter set?

Yes, if you want variety over depth. It lets you try many single notes before buying full-size bottles of the ones you use most.

What comes in the box?

28 bottles of 10 ml each, covering lavender, tea tree, peppermint, eucalyptus, rosemary, citrus oils, florals, herbs and spice oils, packed in a gift box.
