This jutsu also has its disadvantages. The spray heals anyone that comes in contact with it, so the opponent can heal any wounds inflicted upon them. This technique is best used at a distance in battle. Also, the spray only handles surface wounds. If the wound is too deep, or is internal, the spray will not have much affect. However, for deep cuts, the healing water can be sprayed directly on the wound in a concentrated jet to heal it. Also, the spray has an antiseptic effect, killing any bacteria within a wound. This jutsu is advanced however, and requires great chakra control to utilize properly.
