Water Soluble Essential Oil for Humidifier / Diffuser / Refill for Reed Diffuser Available in 120ml & 30ml in an amber dropper bottle. This water soluble oil has a fresh and clean scent. It helps reduce stress and tension. It's very calming, promotes restful sleep, mood uplifting, and serves as a disinfectant to your surroundings when diffused. The rule “less is more” should guide you. Start with less drops first and then adjust the amount later on to suit the size of your room and your individual taste. Diffuse intermittently otherwise you get desensitized. I normally put 8ml in a 400-500ml humidifier. I blend my water soluble oils per litre which means my stocks are new. People have different sense of smell . I am hit or miss with my water solubles - kindly read the reviews. Buy at your own discretion. #vestuarioessentials #everythingishandcrafted #watersolubleoil #lavender
