Essential oils that smell like nature can bring the outdoors inside with their earthy and fresh aromas. Oils such as pine, cedarwood, vetiver, frankincense, and sandalwood are reminiscent of forests and woods. Additionally, floral essential oils like rose, jasmine, neroli, or ylang-ylang can evoke the scent of blooming flowers in nature. Using these oils in candles can help create a calming and serene environment in any space.
