Turmeric is not supposed to be eaten in great quantity, either is cinnamon - so I would no add a lot to a recipe - I doubt, according to that thread that it would be necessary.
I have also seen cinnamon listed as a skin irritant in places on the net (both cassia and cinnamon oils are mentioned as skin senitising in the book (linked below) - so I recommend patch testing first - eating a small amount of a spice is one thing - wearing it for a few hours is another matter entirely.
