*[Iijutsu • Oxygen Flow]
D-Ranked Ninjutsu
Simple in its form yet highly effective in practice, the *[Iijutsu • Oxygen Flow] technique allows its users to clear obstructed airways, to perform less extensive CPR, and to give cells the oxygen they crave. After focusing chakra into the hands, the user will place both over the target's chest (through the back works as well). By allowing the chakra to be channeled throughout the lungs and up through the air ways, any unseen, solid or liquid obstructions will be cleared from these passages and ejected through the mouth, allowing the patient to breathe more easily. Additionally, the hands can be placed over the heart to help oxygenate the body's cells. In this instance, users must be much more careful, as over-oxygenating cells can cause more harm than good. This technique takes the entirety of one post to perform.
*[Iijutsu • Blood Clot Technique]
D-Ranked Ninjutsu
This highly useful field technique is applied to bleeding wounds to help encourage the coagulation of the blood. After focusing chakra into his/her hands, the user will hover them over the bleeding wound and begin to channel chakra through it. The chakra will began to thicken the blood, causing it to clot. Wounds must be dealt with one at a time, and the number of wounds that can be tended to within the three (3) posts that this technique lasts depends on their size. Small wounds take very little time to clot, while moderate wounds take one (1) post of concentration to clot, and large wounds take two (2) posts to clot. Although this technique stops the bleeding, the wound remains vulnerable and will require further care after this has been performed.
*[Iijutsu • Chakra Stitching]
D-Ranked Ninjutsu
When traditional stitching supplies aren't available, *[Iijutsu • Chakra Stitching] truly shines. After performing a short set of handseals, the user will gently place his/her index finger at the base of the patient's wound. Once this is done, the user will lift his/her finger and touch it to the other side of the wound, causing a visible 'stitch' of chakra to appear. This is repeated until the wound has been pulled together. Although precision is key, this technique can still be performed relatively quickly. Small to moderate wounds take very little time to stitch, while large wounds will take one (1) post of work to mend. This technique drains a minuscule amount of chakra from the person it is attached to in order to keep the stitches going, theoretically, ad-infinitum, and can be cancelled at any time by the user with a single handseal. Any intensive or strenuous movements will cause the stitches to break.
*[Iijutsu • Skin Separation]
D-Ranked Ninjutsu
Typically used to make the autopsy process smoother, the *[Iijutsu • Skin Separation] technique separates the skin of the corpse from the underlying muscle. After focusing chakra into his/her hands, the user will slowly move them over the desired area, usually holding them about an inch away from the body itself. As the chakra is channeled through the flesh, it will slowly sink to the final layer of the skin and begin to form a new layer between the skin and the muscle beneath. After this layer has fully formed, the chakra will stay there for four (4) posts, allowing the user to easily separate the flesh and muscle. This non-combat technique cannot be used on living beings as the postmortem physiology is different from that of a living creature.
*[Iijutsu • Burn Ointment Technique]
D-Ranked Ninjutsu
A relatively simple and handy technique to have at hand, *[Iijutsu • Burn Ointment Technique] is used to alleviate pain caused by burn wounds. After focusing chakra into his/her hands, the user will hover them above the burn wound. As the chakra is channeled into and around the burn, it cools the area and works to prevent harmful, scar-producing blistering in the affected area. To provide this soothing relief to small areas of first degree burns, it's fairly quick to do. For small areas of second degree burns, it takes one (1) post of concentration to achieve the same effects. This technique is ineffective when applied to larger areas or burns worse than second degree.

*[Iijutsu • Numbing]
C-Ranked Ninjutsu
This field-oriented technique is used in place of typical anesthetics when they're not at hand. After focusing chakra into the hands, the user will place them over a group of muscles. As the chakra is channeled through the chosen area, numbness will begin to creep throughout it, beginning with the flesh before seeping into the muscle below. Small areas of numbness require very little time, while medium-sized areas (equivalent to half a limb) require one (1) post to numb, and anything larger than an entire limb requires two (2) posts of concentration to numb. This numbing begins where the user has placed his/her hands and spreads outward until the hands are removed. The numbness can only cause pain equivalent to being stabbed with a kunai to be nullified. Once numbed, the effects last for four (4) posts before fading.
*[Iijutsu • Skin Generation]
C-Ranked Ninjutsu
Often utilized by medical-nin to heal small, superficial wounds or for producing excess skin to use in skin grafts, the *[Iijutsu • Skin Generation] technique has its number of uses. After focusing chakra into his/her hands, the user will channel it into a small area of skin cells on the patient's body. This chakra will force the skin cells to multiply at an ample rate by confusing this area of the body into its reconstruction stage that is achieved during slumber. As this is a type of regeneration, users must keep in mind that each cell draws from nutrients in the patient's body, and as such, too much can cause serious harm. In order to regenerate medium-sized areas of superficial wounds, it takes one (1) post of concentration. Areas smaller than this take considerably less time. In the case that the skin sample is separate from the body, the cells can be multiplied more quickly than they could be otherwise. These types of samples are generally use for skin grafts. The *[Iijutsu • Skin Generation] technique can be held for four (4) posts.
*[Iijutsu • Medical Diagnosis Technique]
C-Ranked Ninjutsu
Prerequisite: 5 Iijutsu
Perhaps one of the most important Iijutsu techniques to date, the *[Iijutsu • Medical Diagnosis Technique] allows its users to probe another's body in search for medical answers. After focusing chakra into his/her hands, the user will begin to channel it into the patient's body. Using this chakra as an internal extension of his/her hand to feel for abnormalities and other issues, the user is often able to determine the problem after some time and concentration. In order for a thorough examination to provide sufficient answers, the user will focus for up to one (1) post, seeking signs of internal and external damage, organ malfunction and disease among other ailments. Although skilled medical-nin have the possibility to work faster, skill cannot be substituted in for thoroughness.
*[Iijutsu • Cleanse Technique]
C-Ranked Ninjutsu
In the event that creating an antidote is not possible, users of this technique can still help their patient fight off toxins, infections and other foreign bodies. After focusing chakra into his/her hands, the user will begin to channel it into the patient's body. As this chakra flows into the body, the leukocytes will react to its presence and begin to multiply rapidly. This influx of white blood cells takes one (1) post of concentration to create. Over the course of five (5) posts, the new and old leukocytes are able to fight off poisons that are C-Rank and below that have entered the body. During these final five posts, the medical-nin does not need to continuously focus chakra into the patient. It will take care of itself at this point.
*[Iijutsu • Burn Treatment]
C-Ranked Ninjutsu
Prerequisite: *[Iijutsu • Burn Ointment Technique]
A step up in the ability to treat burns, *[Iijutsu • Burn Treatment] is used to alleviate pain caused by burn wounds. After focusing chakra into his/her hands, the user will hover them above the burn wound. As the chakra is channeled into and around the burn, it cools the area and works to prevent harmful, scar-producing blistering in the affected area. To provide this soothing relief to medium-sized areas of first degree and second degree burns, it's fairly quick to do. For small-sized areas of third degree burns, it takes one (1) post of concentration to achieve the same effects. This technique is ineffective when applied to larger areas or burns worse than third degree.
*[Iijutsu • Blood Transfer Technique]
C-Ranked Ninjutsu
A simple technique that requires its users to sacrifice a little to save a life, the*[Iijutsu • Blood Transfer Technique] does exactly what its name suggests. To prepare for this procedure, the user must make a small incision into the patient's body and follow by opening a vein. Once the vein has been open, the user will begin to channel chakra into it. Over the course of one (1) post, the patient's blood will gain density and stabilize itself. Users of this technique must be aware that their own blood will dilute over the duration of this technique, as it is essentially transferring blood from their bodies to the patient's. No more than 1 liter (2 pints) of blood can be transferred using this technique without severe repercussions for the user.
B-rank
*[Iijutsu • Paralysis Removal]
B-Ranked Ninjutsu
This handy technique is used in cases where patients have suffered temporary paralysis somewhere throughout their bodies. After focusing chakra into his/her hands, the user will apply them to the affected area and begin to channel chakra through the muscle tissue. As this chakra interacts with the temporarily lame muscle tissue, it will restore natural mobility to the area. Areas as large as an entire limb will take one (1) post of concentration to release, while releasing half the body from paralysis will take two (2) posts, and finally, to undo the entire body from paralysis, it takes three (3) posts of concentration. This technique is only effective on paralysis caused by jutsu or certain poisons.
*[Iijutsu • Bone Regeneration Technique]
B-Ranked Ninjutsu
Although simple to explain, the *[Iijutsu • Bone Regeneration Technique] requires both skill and patience in order to mend the fractured or broken bones of patients. After focusing chakra into the hands, the user will begin to channel it through the area of the break or fracture. As this chakra makes contact with the bone, it will stimulate the calcium production of the body and begin to mend the bone. To mend small-to-medium breaks, it takes one (1) post of concentration, while fractures are usually very quick to mend. Multiple breaks can be mended during the use of this technique as it lasts for a total of five (5) posts or until canceled. Users should beware that, like other regenerations of this kind, the nutrient stores of the patient's body are being depleted during its use, and too many uses of this technique in a short span of time can cause serious damage.

*[Iijutsu • Secret Healing Injury Destruction]
A-Ranked Ninjutsu
An advanced technique that requires both quick reflexes and prediction, the *[Iijutsu • Secret Healing Injury Destruction] technique is highly formidable due to its effects. In the event that the user is aware that they will be hit in a specific place, s/he may attempt to focus chakra into that area before the strike connects. If successful, any damage to the damaged area will immediately begin to regenerate, be it a bruise, small fracture, or a small-to-moderate cut. These wounds can take up to one (1) post to heal fully depending on their size and severity, where fractures and moderate wounds would take the entire post. However, during this regeneration process, users are not rendered immobile and can continue to fight while their wounds regenerate. This technique can only be used a maximum of three (3) times per thread.
