This technique creates a volley of small fireballs, which are sent flying in an unpredictable manner assaulting the enemy. In addition, the flames are controlled individually with chakra, so avoiding them all is extremely difficult. Shuriken can also be concealed within the flames, creating an unexpected secondary surprise attack. Like the flames, the shuriken can be controlled with chakra. For the most part, however, this technique is used as a distraction.
This technique's name is a pun on balsam (鳳仙花, Hōsenka, Literally meaning: phoenix sage flower), a type of flower. In fact, when the technique was first used in chapter 46, it was written as "Fire Release: Phoenix Sage Flower Technique" (火遁・鳳仙花の術, Katon: Hōsenka no Jutsu).
