Blue lotus (Nymphaea caerulea) - some advice please

Hey everyone, I bought Nymphaea caerulea (Blue lotus) to make some tea with it. I’ve read that it is incredibly rare to come by so I assume this is another species and not the real thing.

Was looking for an expert on this to give me an indication to what this might be?

I’m mainly interested in knowing if it is safe to drink and if it might have a similar effect (mainly interested in the slight calming / relaxing effects, they don’t have to be that intense). Let’s say a very strong chamomile relaxation effect would make me happy already. Noticeable, but not overwhelming.

Any advice or thoughts on this product by the looks of this image? Would really appreciate it. Thanks!
