Ah that's a tricky one.
The fresh corianer is fine.
I think that chili powder is Ok ,so assume that a small bit of fresh can't be too bad. (sweet pepper ie capsicum is not allowed as it has a lot of natural sugar)
The ginger is more tricky. I can't find a refernce on line for either stem or root ginger. However you don't say if you're going to eat it or just use it to flavour & them remove it. (goes without saying that ginger in syrup is forbidden)
sorry i can't help more. my instinct is to make the thai curry ,enjoy it, then test your wee with ketostix in the morning to make sure it was all ok.
