Does anyone know much about essential oils? Mainly Lavender and Rosewood? I've been using Carex Lavender & Rosewood hand santiser (a couple of times per day at least for the past few weeks, whilst commuting etc) and today the smell of it is making me feel a bit sick. I googled lavender to see if it could cause sickness in pregnancy or something, and was shocked to discover we should avoid lavendar essential oil during pregnancy! The bottle states that the product contains "Lavender & Rosewood essential oils" - should I be worried?
