1 Ravensara (R.aromatica) smells of a Cinnamon-Eucalyptus, and is also considered not as Therapeutic, but is used a lot for its Fragrance.  Ravintsara (Cinnamomum camphora) smells more of a Champhor-Eucalyptus, and is used when it is needed for Therapeutic purposes like respiratory help or shingles.
Hmmm, the smell of fresh Wiri-Wiri peppers. I have them soaked in vinegar and frozen so as to add in every Guyanese dish. Meroza, I myself had no luck with Wiri Wiri pepper plants, they died as soon as Canadian Fall arrives.
