Circumin may raise acetylcholine. I learned that from this old thread:

I take artane to reduce my acetylcholine, so I'll use circumin if I start to take drugs that increase my L-Dopa. It's the ratio of dopamine to acetylcholine that's important. If too much acetylcholine vs less dopamine, you get symptoms.
