Iryō Suiton (Medical Water Style)
Water is the most essential nutrient for the body, without it you will die. It also works as one of the best mediums for Medicine and Antidote creation as discussed in Medicine Creation, and Antidote Creation meaning it can carry other substances as well as being one of the best solvents being able to break down other substances. It also has the ability to channel and be imbued with chakra.
Medical Water Style revolves around the versatility of water as you learned in Poison Extraction water is a chakra receptive medium compatible with the human body meaning you can use it to pull out poison and use it as a container for said poison without causing harm to the patient and minimizing the potential of poisoning yourself. You also learned in Poison Extraction that it is a technique that is less effective against highly advanced poisons that have very fast acting times.
Imagine you're in a situation where someone has been poisoned on the battlefield, or in a hostile scenario. You have very little time to react and you definitely do not have the time to extract the poison and build an antidote. The following technique can be a response to that scenario.
( Iryō Suiton: Suika ) - Medical Water Style: Water Mosquito
Type: Supplementary
Rank: A
Range: Short
Chakra: 30
Damage: N/A ( -20 damage as the poison is removed )
Description: After using the Tiger seal, the user creates water mosquitoes, that can be used to nullify poison in a target's body. Designed specifically to suck out poison, the user is unable to use anything else while concentrating on the target. Despite being a healing jutsu, the several mosquitoes cause pain to the body as it heals it.
How does it work?
The jutsu works in a very similar way as to (Iryō Ninjutsu: Doku Ekiso) Medical Technique: Poison Extraction Jutsu but it is a two pronged approach to the process of poison extraction and nullification. By taking water for what it is a chakra receptive medium you are able to create water constructs in this case mosquitoes that are able to absorb the poison directly from the bloodstream while in unison nullifying it.
Why don't we learn this first?
It takes much more concentration and focus from the user and causes much more pain for the patient but it is quicker, and more efficient at the job. You are able to both extract and nullify the poison with just the technique itself however knowing how to build an Antidote is a fundemental skill for any medical shinobi and without the ability to do so you are unable to understand the principles behind advanced Poison Release.
Water can store chakra, as shown with the use of Water Release itself it's the fundamental principle behind how Water Release is preformed you imbue chakra into the medium and control it, manipulate it and use it offensively or defensively.
( Iryō Suiton: Mizukurage ) - Medical Water Style: Water Jellyfish
Type: Supplementary
Rank: A
Range: Short
Chakra: 30 ( restores up to 200 chakra and heals up to 200 damage )
Damage: N/A
Description: By applying jellyfish to a person's form in advance, the jellyfish can store up and spread chakra throughout its host to allow for quick recovery from a recent injury. This technique drains the jellyfish completely, causing each use to have a one time use.
Note: Can be used twice in all.
How does it work?
This technique is no different by imbuing chakra into water you are able to create another construct. A Jellyfish that has the ability to absorb, store and spread chakra throughout it's host allowing them to recover from an injury. Specifically upon a stimuli eg a new wound the user or patient is able to mentally command the Jellyfish to release it's store of chakra restoring the patient's chakra and healing their body rapidly.
Why use this instead of something else?
This allows you to provide a safety net for yourself or a patient or ally. Transferring chakra or healing a patient can be a very labor intensive process. You must focus on the job at hand, and breaking focus could cause damage instead of healing. This allows for a quick fix, a band-aid of sorts that allows you to apply medical attention and immediately move on no longer needing to worry about if it will work or not.
( Iryō Suiton: Mizukamakiri ) - Medical Water Style: Water Praying Mantis
Type: Offensive
Rank: B
Range: Short
Chakra: 20
Damage: 40
Description: After forming four hand seals, the user can form giant insect-like claws on their arms made of water, extending the range of attack. One can also apply chakra flow through the claws akin to the chakra scalpel, increasing the attack's sharpness and thus penetrative force.
How does it work?
Finally if you look at Water Release you'll see various jutsu that create strong constructs out of water through the use of chakra. By applying these principles to medical ninjutsu a medical shinobi is able to create strong blades on their hands out of water.
These will appear insect-like in nature but work in a similar way as the chakra scalpel allowing for precision cuts, incisions and lacerations to be produced. A cunning medical shinobi can learn to use these to create pinpoint specific damage to things like tendons, nerves, blood vessels and connective tissue and like the Chakra Scalpel Technique allow the medical shinobi to cripple an opponent.
