YLANG YLANG

While generally grown as a tree, dwarf varieties can work in pots. Prefers warmer climates. The heady, sweet aroma of the tropical ylang ylang plant might not be to everyone’s liking but this plant, traditionally used in Indonesia as an aphrodisiac, is often utilised by aromatherapists as an antidepressant and sleep aid.

A 2006 study found that simply inhaling it can slightly lower blood pressure.

Steeped in water and used as a skin and hair tonic, ylang ylang can also balance oil production on the skin and scalp. Simply drop some flowers in a warm bath for a soothing effect, or mix with orange blossom for a DIY potpourri.

Note: high concentrations of ylang ylang can cause headaches or nausea. Some people are more susceptible than others to this effect and will generally react immediately.
