Is There a Cure?
The particular toxin in pufferfish, called tetrodotoxin, has a peculiar habit of making its way through the body, shutting off the electrical signals sent by nerves (causing numbness, usually beginning in the mouth and then spreading [link widoczny dla zalogowanych], depending on the severity of the poisoning).
There is no real cure for poisoning by tetrodotoxin, though there are treatments which possess varying degrees of effectiveness.
Clearly, neurotoxins are not something which should be taken lightly, and don’t think for a moment that tetrodotoxins are the only ones. In fact, they may not even be the worst.
It’s no wonder the Central and South American natives were known to rub their arrowheads with these frogs – it gives it that extra boost of deadliness that a normal arrowhead lacks.
The most effective treatment involves emptying a victim’s stomach of its contents (that is [link widoczny dla zalogowanych], half-digested pufferfish or one of those even rarer animals which possess the same toxin), then forcing the ingestion of activated charcoal (a carbon-based product) which bonds with some of the toxins, preventing them to a certain extent from causing harm.
While amongst some this might be open to debate, the worst neurotoxin most likely is Batrachotoxin.
The name itself is rather frightening; a toxin which affects the neurological system (that is, the system which revolves around the brain).
Why is this? It is because pufferfish, while alive, have bodies filled with neurotoxins, and only if cooked appropriately are they safe (otherwise they can be very deadly).
What are Neurotixins?
So what happens when a person finds themselves having just accidentally ingested some form of batrachotoxin? Nothing good.
Like tetrodotoxin, this stuff quickly affects the body’s sodium channels, though unlike the pufferfish’s poison, batrachotoxin directly affects the heart muscles, causing severe symptoms which lead, more often than not, to a quick case of cardiac arrest. It’s quick, and perhaps even more pl
Then, the toxins bind themselves to pores on sodium channels which send electrical current through the myocytes (the cells which cause muscles to contract), which inhibits muscles motion, effectively paralyzing the victim.
Fortunately, these toxins only really affect certain fast sodium channels, where the muscles of the heart are made of slow sodium channels, so the toxins have no effect on the heart. This is little consolation, however, as death often occurs from the paralysis of the lungs and a resulting collapse of the cardiovascular system while the victim is often entirely lucid, though paralyzed.

Batrachotoxin
This is the stuff that is most commonly found South American Poison Dart Frogs (well-respected as the most venomous vertebrate roaming the Earth today) [link widoczny dla zalogowanych], which coats their entire colorful bodies, making them absolutely deadly even to the touch.
After this, the idea is really just to wait and see what happens. While upwards of 80% of those paralyzed by tetrodotoxin die within the first 24 hours, if a victim can make it longer than this, the odds are very good that they will make a complete recovery to full health as the toxins finally begin to flush from the system and the paralysis lessens.
How much batrachotoxin does it take to kill a person? One hundred micrograms. An amount roughly the size of a couple grains of table salt.
Certain foods are more dangerous to eat than others. Pufferfish, for example, is a delicacy in parts of Asia, yet is practically untouched elsewhere.
