Oil of May Chang is a comparatively new essential oil to the West.

It is steam-distilled from the pepper-shaped fruits (Cubeba) of this tropical tree.
The strong lemon odour of the main constituent (Citral - 75%) dominates and hence the oil resembles Lemongrass, although it has a rounder and more fruity aroma.
Like Lemongrass, May Chang is used for the isolation of Citral for lemon flavours and for the production of several perfumery materials, as well as Vitamin A.
While the synonym Litsea Citrata is often given for May Chang, Litsea Citrata is a related species with a lower Citral content.

A wonderful citrus aroma which uplifts, cleanses and tones.
May Chang is an excellent room deodoriser and insect repellent - use 5 or 6 drops in a traditional candle burner, Aroma-Stone or Aroma-Stream.
For oily or problem skin, try adding a few drops of May Chang to skin cleansing products to boost astringent and anti-bacterial properties (not suitable for sensitive skin).
