You need the healing team of harvest sprits. To get one of them go buy a drink from the blue bar. To use their power go to the casino in the sprit tree; play some games and get some coins; go to the sprit at the front desk of the and ask for the healing team to work, choose how many days and the map square you want them to appear at. The more you use these sprits the more the are able to heal you.
