[Nin] Medical Ninjutsu
- Thread starter Corazon
- Start date
Medical Ninjutsu is a subsection of Ninjutsu that revolves primarily around healing, though, this is merely a portion of what it encompasses. While its basic function is to enable Med-Nin to properly treat injuries and perform surgeries, there are cases where people skilled enough are able to utilize it offensively, capable of severely injuring people internally by targeting vital spots and creating Poisons that can easily paralyze/kill target.
In addition to the things mentioned above, it is a skill that enables the user to push the human body beyond its believed limits, e.g., it allows them to continue fighting after being severely injured or even double their chakra reserves if they deem it necessary. It is based on knowing the ins and outs of the human body and its capabilities and chakra manipulation of the highest level, simply put, its an ability that could save a life but, just as easily end it.

Iryō-nin (Medical Ninja)
A medical ninja is a ninja who has learned to make use of Ninjutsu and related skills to provide medical treatment to others. It also encompasses those that, using that knowledge, have enhanced their own combat abilities.
In Naruto Manga, fields like Kinjutsu, Fuuinjutsu and Poison techniques are deeply rooted into Medical Knowledge. Orochimaru is a fair example of how Medical Knowledge can be used to achieve greater power but he isn't the only one.
In Narutobase RPG, the medical ninja is capable of healing others and himself, cure poisonings, enhance his sealing knowledge and skill, develop his regenerative abilities and even learn to use poison techniques in combat.
Medical Ninjutsu is not unlike regular ninjutsu where you use your chakra to achieve effects that you would not be able to otherwise. Most Medical Ninjutsu techniques, however, are deeply rooted into Yang Release and make perfect use of Physical Energy.
The following is the method to which a med-nin can deduce a patients ailments in order to heal them... or deduce your own ailments and heal them:
Shindan (Diagnosis)
A Medical Ninja needs to start somewhere and that somewhere is detecting the issue with your patient. Shindan or diagnosis is the first step in treatment; understanding the problem. With this skill you use your hands to carefully probe a patient for problems that you might not be able to see. Contact with the patient will initially be needed but with time becomes optional. Despite this, you'll always need a close proximity between your patient and your hands. This technique is preformed by approaching the patient and slowly running both hands over his or her body, using your chakra to examine the body and looking for signs of injury that may not be visible to the naked eye. It can detect any physical alteration to the body (internal or external wounds, lesions, tumors, fractures, diseases, etc) as well as its composition (glucose levels, iron levels, antibodies, etc ) and vital signs (blood pressure, heart rate, temperature, pain levels, breathing, oxygen saturation, etc).
A student of Medical Jutsu will require several minutes to assess all the details but a medical ninja will be able to do so in mere moments. To help less experienced ninjas or to aid in complex cases, direct contact is often used as well as chakra transmiting mediums such as water, wood, etc.
Mental injuries such as psycosis, depression, bipolar disorder, etc can be determined as well. In this case, however, scanning the patients head is necessary. By scanning the various hormones, chemicals as well the electrical currents that make up the inner working of the brain, the medical ninja can detect any inbalance and to what it might be due. He cannot read minds but he can understand if there is a disease or a Genjutsu present.
Additionally, all medical ninjas can use this skill to sense the patients chakra flow. Its by sensing the chakra flow that most of the times injuries and disease are noticed and diagnosed. Ninjas have their physical being greatly intertwined with their chakra, making so that an injury in one will result in changes to the other.
Finally, after gaining mastery over medical jutsu, a medical ninja becomes even able to examine dead bodies, determining cause and time of death.
Let me just explain how Shindan works a bit better, for everyone.
The idea behind it is that you will send your chakra through another body (your hands are the main focus here and its through its tenketsu that you'll release the chakra) and then will it to return to you with the information you need. That means that it doesn't matter whether you will touch the person or not or the location of your initial scan at all; the chakra will find the root of the problem and the manifestation of it. This is the information you require.
You can use chakra transmitting mediums, such as water, to improve you diagnosis and its effectiveness. The easier it is for your chakra to enter the body of the patient and return, the more information you'll be able to attain. Water has the innate ability to assist us in transmitting our chakra to better diagnose a patient. Some justu utilise water to assist in healing, stemming from RL cultures were healing is seen as a healing element and often associated with healing.
Now, to achieve this you need advanced chakra control and practice. Too much chakra and you risk harming the patient. Too little and you might not get enough information out of it.
What skills, KGs and abilities might help the medical ninja in this procedure?
Any advanced sensory enhacement helps the ninja adquire information in a more detailed manner, faster and without needing so much time. The main examples are:
-Sharingan: the ability to see your chakra flow and is characteristics as well as the ability to gain advanced visual perception in general helps to better identify the issues with the patient.
-Byakugan: perhaps the most useful of all the abilities that can help a medical ninja, the Byakugan allows you to see inside the body, piercing through the flesh and looking at the core issue in detail. Additionally, because you can see the chakra circulatory system completely and in detail, you can gauge the extent of the damage and if it somehow has anything to do with his chakra flow.
-Rinnegan: seems to have the same/similar perception to the Byakugan and Sharingan in that it can see chakra and chakra flow, but it doesn't grant you the ability to see the chakra network and tenketsu to the same detail as the Byakugan.
-Chakra Sensing: As said above, most injuries and diseases affect the chakra flow. By being able to sense disturbances in the chakra flow of your patients you are able to better understand their nature and extents.
-Enhanced Hearing: This can help you better evaluate biological functions such as breathing, heart function, intestinal function, blood circulation, blood pressure, etc.
-Emotion Sensing: While we talk about injuries of the flesh, the medical ninja also needs to treat injuries of the mind, often associated with Genjutsu. To better do this, sensing the emotions of your targets might help greatly.
So here is the open discussion part, voice your comments, questions, concerns or anything else you might want to say about these classes.

Teikouryoku (Power of Resistance)
Before one can treat patients, one needs to protect himself. In real life, medical staff use gloves, masks, etc. But for a Medical Ninja in a battlefield, that's not practical. A Medical Ninja must always be aware of becoming a victim of whatever their patient is suffering from so he needs resistance to disease. With this skill you, as a Medical Ninja, increase your natural resistance to most natural diseases and toxins as well as most man made diseases and poisons, allowing you to threat an infected or poisoned patient with a higher safety. It has no effect on diseases or poisons already affecting you though. This skill, as all others, improves as you grow in power and affords greater resistance to a wider range of diseases and poisons and can become something that you don't even need to focus to achieve.
However, there are limits. This skill will essentially provide a boost to your natural resistance to disease, poison, toxins, acids, alkaline substances, etc but will only basically provide a "shield" of sorts around you. This shield can be overcome, like all others, by overpowering it. This essentially means that you cannot use this to defend from enemy offensive techniques in the midst of battle.
If you decide to and gain Poison Mastery, allowing you to make your own Custom Poison and mastery that branch of medical arts, this skill will allow you to become immune to regular none custom poisons and to your own poison.
How is it performed?
Now, to do this, you need to focus on your chakra at its core. This, when you look at the chakra circulatory system, is the central spiral network of chakra paths thats surrounds your chakra source, normally located in your abdomen. When you focus on it, you need to visualise a growing yellow and warm aura, spreading from your core, outwards towards your skin. Its this focus and this will that will make your chakra passively aggressive towards pathogens and most natural toxins and infectious diseases. This chakra is invisible to the naked eye and doesn't go beyond the users skin. However, doujutsu might see the aura growing and expanding from the medical ninjas core.
Its this a technique?
Teikouryoku is not a technique, has no chakra cost or is otherwise performed in any way remotely similar to a Jutsu. It is a passive skill, much like diagnosis, taught in the medschool, that gets stronger with time; the more you work with it, the better it will protect you against contagious diseases and poisons.
Are there different stages to its effectiveness?
Yes.
Medical Student: can maintain this skill active for a few minutes, enough to treat a single patient but needs effort and to will it to happen. Its impossible to keep active at all times.
Medical Ninja: the skill can be active for as long as he wishes and he doesn't need to dedicate any kind of mental command or focus for it to work.
Poison Master: Not only is the skill the same as the one for regular medical ninjas as it can protect the user from his own Custom Poisons and similar techniques (for example, toxic/poisonous/venomous elements) at all times.
This is just an explanation as to how you would be immune to your own poisons and then immune to cannon poison release, which is no longer a medical thing so I don't believe this lesson should be here any longer. Regardless, I'll make this lesson worthwhile by 'teaching' you the following jutsu, which you'll be able to use as soon as I move on to the next lesson.
( Iryo Ninjutsu: Doku Teikouryoku ) - Medical Technique: Poison Resistance
Type: Supplementary
Rank: N/A
Range: N/A
Chakra: ( 40 per turn )
Damage: N/A
Description: The user will raise his resistance enabling him to stop the progression of a poison, toxin or venom he might have been contaminated with after feeling its first effects. This will not cure the poisoning but rather stop its progression so the user can continue to fight, hopefully winning the fight, to then be able to treat the poisoning. This is a skill that only consumes a move when activated, passively draining chakra, focus and stamina from the user as each turn passes.
Type: Supplementary
Rank: N/A

If you get infected by a poison and, like genjutsu have reasonably deduced you are poisoned/infected, you can stop any further progression of the poison past the current effects you feel. It will cost you a lot of chakra over time, however you'll learn jutsu to remove poison. Fuuinjutsu provides a quicker way to remove poison, while Medjutsu has two cannon methods to remove it.

Kuchiyose No Jutsu (Summoning Medical Tools)
A medical ninja, regardless of his skill, will always face situations in which he'll need medical tools to treat patients. Be it to create antidotes or medicine, but to also stitch or bandage wounds, you'll always need to make sure you can access medical tools and supplies to treat patients.
*Hands out a scroll to each of you*
This technique allows a Medical Ninja to summon some of the tools of their trade. It is not practical to carry around syringes, scalpels and other tools but a scroll that can be used to summon these and other similar objects is both practical and convenient.
So as for any good summoning jutsu, you need your blood and a few kanji which you can all find in your scroll. You are expected to carry it with you at all times. It includes:
(Kuchiyose No Jutsu: Eisei Yougu) Summoning technique: Medical tools
Type: Supplementary
Rank: B-Rank
Range: N/A
Chakra cost: 20
Damage: N/A
Description: The medical Ninja will bite his thumb and do the summoning handseals before pressing his palm on the scroll. He will summon any of the medical tools he needs that are listed on the scroll, all or just one, depending on his own needs.
Note: This can only be used by Medical Shinobi.
List of summoning items:
メス - scalpel, sterilized
ナイフ - knife
アルコール - a bottle of 96% ethanol for disinfection
水 - a bottle of sterilized water
スポイト - syringe, sterile, for one time use only
アドレナリン - adrenaline, to be injected intravasulary, induces faster heartbeat
包帯 - bandage, sterile, 8 meters in length
血液 - a set of everything you need to draw someones blood (Sterile syringe, vacuum system and a test tube.)
温度計 - mercury thermometer, for axillary or rectal use
ベッド - a mobile bed to carry patients
バグ - bug spray, effective against all bugs, lasts for 2 turns (used in cases when your patient is having a reaction to multiple bug stings, and there are still some bugs around it, so you spray-kill them. Kills bugs up to A rank if they've been created/summoned from a jutsu like the Aburame techniques)
テント - a small tent, just enough for two people to lie in
光 - a flashlight
ガスマスク - gas mask with a bottle of oxygen that lasts 5 turns (Not 100% effective against all types of poison/gas. The purpose is to protect the user from breathing in toxic substances, keeping the lungs safe. However, if the poison gets absorbed through the pores of the skin it will still affect you).
流体 - a set to start an intravenous fluid addition line, helpful with dehydration amongst many other conditions
モルタル - mortar and pestle, chemically clean
スプーン - spoon, sterile
パテ - putty knife, metal, sterile
研究所 - a small tent. Into the walls of that house, parts of Nexus' eyes DNA have been inserted, so now it mixes Time And Relative Dimensions In Space , creating an effect of being larger on the inside then it is on the outside. Inside is an advanced ninja laboratory with everything needed to create antidotes and medicines.
So yeah, there's some things you can summon, for healing and stuff. Some nice things for WSE RP too!

Jokyo Dokubutsu (Poison Removal)
Okay so this is a tricky one 
. To begin with, this technique does not cure a poisoning; it simply extracts a portion of the poison and prevents immediate death by delaying the ongoing poisoning. It mainly allows a medical nin enough time to prepare an antidote for the poison and to slow down the effects of a poison used against the medical nin so as to give them time to escape or prepare an antidote for themselves. A patient will still die from a lethal poisoning even if this technique is used if the poison is not treated. Truth be said this technique is less effective against highly advanced poisons that have very fast acting times.(Iryō Ninjutsu: Doku Ekiso) Medical Technique: Poison Extraction Jutsu
Type: Supplementary
Rank: B-Rank
Range: Short
Chakra: 20
Damage: N/A
Description: An advanced medical jutsu used when the user cannot make enough antidote to cope with a poison. This is used to extract a great deal of the poison from a body, and then the antidote can be administered. The user will need a medium (his own chakra or a chakra receptive medium compatible with the human body, like water) which he will insert into the patients body, using his chakra to gather the poison directly from the tissues, merging it with the medium to then remove and discard. The technique can only remove a limited amount of poison and will not negate any ongoing effects as it cannot remove poison already being metabolized/in effect. Because of this, the medical ninja will still need to administer an antidote and will need to use the technique twice to remove all of the poison from the patient.
Note: can only be used twice, each use delaying the effects of the poison for 2 turns.
The jutsu works in the way that you insert (either your chakra or another highly absorbable, chakra-reactive medium) into the patients body, where it then looks for the poison in various vital organs, and when it finds it, it binds it to it's own energy and draws it out of the body. If using your own chakra (which you will most of the time) then that chakra cannot go back into your body otherwise you'll poison yourself, you have to discard it, if you're using the previously mentioned medium you have to throw it away. The use of specific chakra receptive mediums helps to mitigate/diminish the risk of self poisoning or injury when dealing with unknown poisons and, more importantly, with corrosive ones.
Removing the poison makes it easier to heal. You remove the "inactive" poison that is circulating the patients body and hasn't yet affected any tissue. By removing that you prevent further injuries and damage into the patient. However, the poison which is already affecting the tissues needs to be dealt with with antidote. If you didn't remove the "inactive", unused one, you'd need to supply antidote for a much longer period of time and would risk losing the patient in the inbetween.

( 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.
Note the damage cause by using the mosquitoes. No water source requires though it does require as much concentration/attention as the poison extraction technique. This does however nullify the poisoning much quicker though damage already caused will still have to be treated.
Q&A
First of all, what would constitute a "highly absorbable, chakra-reactive medium"? Would this be some form of medical tool, or other cannon instrument we could use, or would it have to be, for example, a Custom Weapon which absorbs chakra?
The Highly Absorbable chakra-reactive medium can be Water, Wood, etc. It can be anything that reacts with chakra and is compatible with organic medium. Water was what we saw used in the manga by Sakura but you can also simply use your raw chakra. Wood is a possibility as its organic in nature and would be a nice medium for this. In theory, other elements/materials that are compatible with organic living things or that exist inside them can be used.
Is there any particular reason the technique cannot extract all of the poison? And, building on that question, if several med-nin worked together at once, would they be able to extract all of the poison? Or is the fact that we cannot extract it all tied into how poisons affect our bodies?
Poison will cling to the cells and tissues in a way that prevents you from pulling it all out without damaging the patient in one go. You need to take the first portion first, then redo the procedure to remove the remnants that might be left. In essence, you'll only be removing the poison that is "waiting to act" in the body, not the one already acting. Think of it as cleaning spilled oil on a surface. First you pass a cloth that takes the majority of the oil but there is always some left on the surface. You then pass a new cloth once again to clean whatever is left.
Would this work on other toxins aside from poison, such as, for example, venom? Or would this extract solely poison, and leave us unable to extract other deadly toxins?
We will speak about Poison, Toxins and Venoms further on but to answer your question, in terms of our RP, all 3 are cured in the same manner: remove + antidote.
What is considered an advanced poison? Considering that the technique is only B ranked, I'd assume that everything poisonous above B rank is too strong to be extracted, right?
Advanced poisons are all the custom poisons, the specific poisons. Anything not existing in real life/nature/narutoverse nature. Basically, man made poison. Poison form normal Poison Release techniques are not considered advanced. Sasori's poison is considered advanced poison though severely slow acting.
Something kinda useful, in that you'll learn some jutsu! The jutsu list has changed a bit since this handbook was made, so I've edited in a jutsu that also falls under this category of treatment. You can also use these once you've replied/completed this lesson.

Kaidokuzai Sōzō (Antidote Creation)
This is actually a simple more specific application of Medicine Creation developed solely to counteract Poisons, Toxins and Venoms.
An antidote is a substance you'll administer to your patient that will counteract the effects and the progression of a poison, toxin or venom. It not only neutralizes poisons, toxins and venoms that are in the body and not in effect yet as it also neutralizes them when they are already acting while also countering the effects their triggered in the patient. Basically,you do the same and follow the same principle as in Medicine Creation as an antidote is, basically, a medicine.
But how do we know what to put into the antidote?
For this you'll need to first use either the poison extraction technique or the poison extraction seal. In the case you use the technique, as you'll be using diagnosis in tandem, you'll be able to know, as you gather the poison and extract it from the body of the patient, its components and mainly its effects. If you use the sealing technique, you just unseal the poison and use diagnosis on the poison to the same effect.
Once you know what the poison is made of and what it can do, you'll be able to determine what herbs and solvents to mix to create an antidote. But here comes the issue: how can you, an NB RPear, know what herbs and what not to mix to counter a custom poison for example? Its not easy and it would become overly complex for the RP to make players do this. Thats why it was decided that creating fixed component of all antidotes, called antiserum* thats made of various herbs, antibodies from various animals and humans, that can counteract any and all non specific or custom poisons, toxins and venoms.
*in reality, antiserum is the component of blood in which passive immunity to diseases is "memorized". Basically, once you're exposed to a disease your body will create antibodies to combat, leading you to cure that disease. Those antibodies don't disappear. Instead, your body creates more and keeps them in the antiserum, circulating in your body for a time when the disease might attack again. If that happens, the antibodies will attack the disease before it infects you and you trully gain immunity to the disease. Vacination works on this principle. And real life antidotes to snake and other poisons, venoms and toxins is often produced and derived from large mammal antiserum (horses, pigs, etc).
Ofc, you'll still need to add specific herbs to counter the effects that poison, toxin or venom creates in the patient but you won't need to worry about finding herbs that are capable of neutralizing the poison. Some toxins, poisons and venoms though, have very specific antidotes, clearly known and defined. When its such a case, you simply use that.
Ok, so how does it actually work? And what technique is that?
So, lets start by stages:
- Extract Poison and Analyse it
- Determine the effects you need to counter and if the venom/toxin/poison has a known antidote
- Gather the antisserum to counter the poison plus all the active ingrdients needed to counter its effects plus a suitable medium for delivery
- Mix them all together and create the final medicine, your antidote
- Administer it to the patient
- Monitor results
But this isn't practical in combat!
Ofc not. Even a very experienced poison master will not be able to counter poisons in combat as you first need access to the poison. However, if you had access to the poison before, you can create an antidote for it and save it on your bio for future uses.
Additionally, you'll always have with you a medical scroll containing all the known herbs you'll need, most mediums/solvents possible and infinite amounts of antiserrum. This way, your own priority is surviving until the end of the fight so you can then produce and administer the antidote for a poison affecting you.
In the long run, however, the best survival possibility is to have someone to treat you if you ever become poisoned.
So, there's really nothing we can do in a fight?
Well, there is a minor technique that might save you long enough to produce the antidote. But its no sure method. This technique is a variation of Power of Resistance but directed at Poisons and Toxins. It works by halting the progression of the poison using chakra, focus and will power. It can't be used until the first effects of the poison are felt though, so you won't be able to fully remain unscaved. Its a self usage technique that cannot be used on others.
Upon feeling the first effects of the poison, you'll focus and use the same method as Power of Resistance to raise your resistance but this time you'll visualize the poison and your own body and focus on having your chakra "hold the poison in place". You cannot expel the poison, neutralize it or cancel it. No. You simply temporarily stop its effects. The first effects you felt, will be there but there won't be a progression of symptons for as long as you can sustain the technique.
But then here comes the various limitations. The technique requires constant chakra input so the effort and drain of chakra is enormous. Additionally, if you're in a fight, you'll consume one of your allocated moves per turn the first time you use the skill. While using this will still allow you to use other techniques at the same time (its treated more as a passive skill), the longer you use it, the longer the cost is and the harder it is to focus and maintain the technique.
(Iryo Ninjutsu: Doku Teikouryoku) Medical Technique: Poison Resistance
Type: Supplementary
Rank: N/A
Range: N/A
Chakra: N/A (40x(Z), with Z = the number of turns while using it)
Damage: N/A
Description: The user will raise his resistance enabling him to stop the progression of a poison, toxin or venom he might have been contaminated with after feeling its first effects. This will not cure the poisoning but rather stop its progression so the user can continue to fight, hopefully winning the fight, to then be able to treat the poisoning. This is a passive skill that only consumes a move when activated, passively draining chakra, focus and stamina from the user as each turn passes.
Note: Poison masters will be able to do this technique with half the chakra cost.
Btw, this technique has no other defensive effect other than stopping the progression of a poisoning once it starts. This poisoning, however, can be of any origin like custom elements or custom poisons but cannot be an infection like from bacteria, fungi or nano-insects.
Materials needed:
Add these to your summoning scroll
抗血清 - antisserum
ハーブ - various medical herbs
溶剤 - various solvents and mediums
All can be used to summon any known medical herb, antisserum and any known solvent and medium. These can also be used for medicine creation if you wish.
