What is Secret Potion?

Question

I recently found something called Secret Potion in my key items pocket (in Diamond), it says it came from a pharmacy in Cianwood city and that it fully heals a pokemon of any ailment.

I have no idea how i got it, i don't think I've ever heard of Cianwood and i can't even use it.

Anyone know what it's for?

Cinawood city is a city where the joto's fighting gym is located. Has a pharmacy there. It is important in the hg SS games.

The Secret Potion I believe is given to you by Cynthia. You use it to cure the Psyduck that are blocking the path north of Solaceon town.
