if you are meaning the medicine for ampharos the sick Pokemon from the lighthouse then it is at cianwood city... there is a place where you can get special medicine for ampharos (the sick lighthouse Pokemon) then take it back to the female (which is the gym leader for olivine.) that is looking after him. then she goes off and you can go battle her in her gym in olivne..!
I hope I've helped

SOulsilver
You CANNOT LEGALLY download Pokemon Soulsilver.
You can't catch bastiodon in Pokemon soulsilver.
You'll need to trade for it from Pokemon HeartGold. It is not avilable in the wild in Pokemon SoulSilver.
there is a mew in Pokemon soulsilver but you need to catch all leadndery Pokemon including event Pokemon
You cannot battle between a Pokemon Black game and a Pokemon Soulsilver game.
Pokemon Heartgold and Soulsilver are the remakes of the old Pokemon Gold, Silver, and Crystal series. Pokemon Heartgold and Soulsilver are for the Nintendo DS.
It is impossible to move a Pokemon from SoulSilver to Sapphire as the two games are from different generations, you can only migrate Pokemon from Sapphire to SoulSilver.
