AshleyK,
Your lady neurologist does not know much about curcumin when she advises you it is toxic.
The conclusion in
http://www.liebertonline.com/doi/abs...ournalCode=acm

is "Conclusions: Curcumin has been demonstrated to be safe in six human trials and has demonstrated anti-inflammatory activity. It may exert its anti-inflammatory activity by inhibition of a number of different molecules that play a role in inflammation."

Also, does she not realise it is present in the Indian diet in copious quantities. Does she also advise you never to eat curries!!!
I wonder how much more of her expensive advice is also wrong?
