Help @ Castlevania NDS

I'm stuck on Castlevania Portrait of RUin.the problem is that mi mainc haracter (jonathan) is curse (the sickness that makes him lose all mp). I gave him a lot of potions but nothings works to make his health good again. I gave him the potion that health curses and when I check the start menu he drinks the potion and it apears at the top that his status gets "Good" but when I quit from start menu he starts again with the @#$@$# sickness. What can I do! he doesn't want to go to b good. dammit help! :(
