Manuka essential oil contains an unusual chemical ' leptospermone ' which has been found to be strongly anti-bacterial and insecticidal. Manuka can be used wherever Tea Tree would be used and because it has a sweeter, less medicinal aroma, it is often preferred for diffusing.
For healthy feet and toes, try 4 drops of Manuka blended with 10ml of Grapeseed oil, add to a warm footbath. Soak the feet for at least 10 minutes, pat dry and apply the remains of the blend.
For oily or problem hair, try 10 drops of Manuka, 5 drops of Rosemary and 5 drops of Lemon in 100ml of unfragranced shampoo or conditioner.
