ESSENTIAL OIL QUALITY – Ravensara/Ravintsara

ravensaraI wrote in an earlier post about an essential oil I picked up: Ravintsara (cinnamomum camphora). I couldn’t really get this oil out of my head so I have been doing some research. As usual there is plenty of misunderstandings between different oils, popular names, botanical names and the chemical properties. What continues to confuse me are the different Latin names but this is what I have found:

Ravensara, (Ravensara aromatica / Ravensara anisataLauraceae family) Is a a leafy evergreen tree 18 to 20 meters high with a reddish-grey bark indigenous to the moist forests of Madagascar, in Malagasy called Havozo. The essential oil is steam-distilled from the stem-bark (Ravensara anisata) or the leaves & branches (Ravensara aromatica)

The main chemical constituents of R. aromatica are: 1,8 cinèole (up to 49%). The main chemical constituents in R. anisata are: anethole (approx. 85%) and methyl chavicol. This makes these two oils completely different.  Ravintsara (Cinnamomum camphora – Lauraceae family) is steam-distilled from the leaves. It is also high in 1,8 cinèole.

The problem is that I cannot find any information on the Ravintsara (c. camphora). All info I can find reverts back to Ravensara aromatica/anisata. So the question is; Is it really the same plant? Or is it a mixup of the names? One source states: “Cinnamomum camphora is also named Ravintsara in Madagascar; hence Ravensara camphora is seen on price lists mistakenly as ravensara but no true species exist; various qualities abound”.

So you see the confusion around essential oils; this is why it is so important to make sure that the oil you buy is good quality and has a Latin (botanical) name on the label. In the case with the Ravensara, I would go for the botanical name Ravensara aromatica.

to be continued…when I have more information.
