Medicinal essential oils can be camphoraceous or can have a therapeutic aroma. Essential oils that tend to have a medicinal scent are Clove, and two oils from the Melaleuca family,Tea tree and Rosalina.
I like blending various butters & oils, and as it is only for myself it is wonderful to have these 'ready-made' combinations. Really enjoy working with them & I think they are a great addition to your products.
