Melaleuca Viridiflora is a member of the Tea Tree family of oils. The tree grows wild in New Caledonia in such profusion that cultivation is not necessary. The oil is extracted from the leaves by steam distillation. It is used as a component in many medicinal or pharmaceutical preparations such as cough drops mouth sprays & gargles. 1 drop each of Niaouli Sweet Thyme & Lavender in the water of an oil burner will help maintain a healthy workforce at the office during the winter months. As an alternative to harsh preparations try mixing 2 drops of Niaouli & 2 drops of Lavender in half a pint of boiled water & gently wash playground-worn elbows & knees.
