Cinnamon sticks, is cassia OK?

[Guest guest]

I remember reading somewhere that commercial ground cinnamon is often cassia and

this was inferior/not SCD legal. I bought some cinnamon sticks in a bag, but

when I opened it they appear to be cassia (Brittle, " double scroll " and lighter

in colour).

Does anyone know whether or not cassia is permitted? I can't remember where I

read about it before. I am planning on grinding them into powder as I am trying

to avoid ready-ground spices.
