Why is Helichrysum so expensive? It is a relatively dry flower which yields very little precious essential oil. That means that a large quantity of plant material is required for a minimal amount of essential oil. Helichrysum is a sacred oil to me with its unique warm, herbal aroma and its amazing anti-inflammatory, antiseptic and vulnerary properties. When dealing with past emotional trauma, or badly bruised skin, this is one I reach for. It is one of the few essential oils that is safe to use directly on the skin but due to its cost, I always dilute it! I recommend you do too!
