Niaouli Essential Oil is good for all respiratory tract infections, whether they affect the nose, throat or chest, and is used in chest rubs as well as inhalations. As it's botanical name implies it is a close relative to Tea Tree. Like Tea Tree it contains terpin-4ol and is great for treating cuts, blemishes, spots and fungal infections. It is quite a powerful stimulant, so it is better not to use it late in the evening, unless mixed with more sedative oils such as Lavender, or sleep may be disturbed.
