Cypress (Cupressus sempervirens)

Geranium (Pelargonium graveolens)

This is a list of safer essential oils for skin use. Remember no oil is safe for undiluted use directly on the skin. Dilute your chosen oil or blend of oils below 2% in a vegetable oil carrier for infrequent use (once a week or less often) and below 0.5% for more frequent use. If you're pregnant, on medications, under 12, or have any sort of major health problems, ask a trained aromatherapist before you use anything. Don't take essential oils internally - you don't know where they've been!
