Cidp And Use Of Nebrical

Just wondering if anyone had heard of this herbal product called Nebrecal.
My mother is now 9 months post CIDP. Still has a way to go with recovery. She started to use Nebrical about 3 weeks ago, and has noticed that her recovery rate is signicificantly better. Prior to taking it, she was feeling like she was at a stand still. Just wondering if others had heard about it.
