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.
