Cinnamosma fragrans, commonly known as Saro, is one of the healing plants native only to the island nation of Madagascar.
Saro essential oil, along with Ravintsara (Cinnamomum camphora ct. 1,8 cineole) essential oil, is harvested from the wild, and distilled in Madagascar.
I suggest using Saro essential oil to prevent a cold or flu from settling in, or to reduce the symptoms once you're already sick. Try adding 6 drops of Saro and 6 drops of Ravintsara to a blank inhaler and using it every few hours to support your immune system when you're just starting to get sick.
You can also add 10 drops total of these two essential oils to an ounce (28 gm) of unscented lotion, and apply some to your chest, back and feet. This can help clear your head and reduce coughing.
When creating a “medicine chest” of essential oils particularly effective in soothing cold and flu symptoms and complications, I thoroughly recommend including Saro essential oil.
