Sakura Haruno first learnt her healing abilities from Tsunade, way back when Sakura first demanded Tsunade while Naruto and Jiraiya, and Sasuke and Orochimaru were training together. Sakura has come a long way from the way she was previously, and I think from the hate she used to get, to now, she seems to have truly grown into a person who is respected.
