The question is what ratio is acceptable for Ibotenic Acid to intake as it also works as a stimulant
- That stimulation you are feeling is called excitotoxicity. Ibotenic acid mimics glutamate, the brain’s primary excitatory neurotransmitter, but it causes the cells to fire nonstop, depolarizing the neurons and sending them into a state of metabolic overdrive, basically using up all their energy and causing them to overheat and die. If you want that neural excitation without the brain damage, you can eat some MSG or kelp with your decarboxylated amanita.
Now with respect to the fact that ibotenic acid is toxic and you should aim to minimize your ingestion of it, here's the numbers you are asking for:
So that brings up the question, if boiling the DRIED Caps, not the fresh ones in plain water, can get the ratio of IBO to Muscimol in such a way, that it doesnt bring on an immediate dreamstate (or drunken state?) while you are still awake, but that you are mildly stimulated by the remaining IBO which through your body slowly converts to Muscimol and you get that dream state right when you go to sleep.
- How much muscimol and ibotenic acid is present is largely dependent upon how the material is dried, I posted a chart for that. You are correct that the initial excitotoxicity will give way to the muscimol effects as your body converts the material, but you are discounting the neural damage that occurs via that process. The simple answer here is to take a safer stimulant or excitatory compound first and take the amanita after, same effect, less the neural damage. I have a friend that loves to chew a small amount of amanita on the LSD comedown for example. Truth be told, if you are just looking for GABAergic effects to ween off stimulation, there are much safer choices than amanita for that as well.
The post is just about finding out, if acidic water is actually necessary or if plain water boiling is better as it converts the IBO but not as a full conversion, but as a slower conversion as probably happens while drying them on fire.
- This is clearly outlined in the charts, but allow me to reiterate once again. The goal is to convert as much of the ibotenic acid to muscimol as possible. There is abosolutely no benefit to not fully completing the conversion and lots of actual harm. There are safer ways to get a glutamate response than intentionally ingesting nuerotoxic compounds.
I doubt that ancient people had any idea of adding lemon juice to the boiling water in order to lower the PH, they had absolutely no information about PH lowering and the Conversion process.
- Now we get to the fun part! What amanita discussion would be complete without urine drinking? Lemon trees don't grow in Siberia, but you underestimate how pharmacognizant these ancient peoples were. Why do you think they were drinking pee? As you mentioned, much of the ibotenic acid is being converted to muscimol in vivo, but muscimol is fairly poorly metabolized once that process is complete. Up to 80% of the musicimol is excreted in the urine wtihin a few hours. So when someone drinks the urine of a person who has already consumed amanita, they are avoiding the toxic effects of ibotenic acid (e.g., nausea, vomiting, excitotoxicity) and accessing a more potent and refined dose of muscimol. So they went as far as drinking someone else's pee to avoid the negative effects of ibotenic acid and isolate the effects of muscimol, I don't know about you, but I'm not that much of a tranditionalist! I'll stick wih a little lemon juice in my tea, thanks.

| Context | Dose | Effects Observed | Notes / Sources |
|---|---|---|---|
| Minimum psychoactive dose (human est.) | ~30 mg oral | Initial CNS stimulation: euphoria, confusion, perceptual changes, agitation | Derived from Amanita muscaria content per cap; average cap = ~6–10 mg ibotenic acid; multiple caps usually ingested |
| Average psychoactive dose (human est.) | 30–60 mg oral | Mixed effects: CNS stimulation followed by ataxia, dysphoria, hallucinations; muscimol likely dominant | Co-ingestion with muscimol complicates isolation of ibotenic acid effects |
| Toxic effects (human) | ≥50–100 mg oral (estimated) | Delirium, ataxia, seizures, deep somnolence, vomiting | Human case reports show wide individual variability; fatalities rare |
| Seizure threshold (human case reports) | Unknown exact dose; likely >60–100 mg | Generalized seizures in severe intoxications | Rare but documented in emergency tox reports |
| Fatal dose (human) | Not well-defined | Deaths from ibotenic acid alone not confirmed; severe cases resolve with supportive care | Mixed ingestion with other toxins more dangerous |
| Rodent oral LD₅₀ | ~38 mg/kg (mouse, oral) | Convulsions, CNS toxicity, neurodegeneration | [Rogers et al., 1982]; [TerMedia 2023] |

, (Ott did? and added juicy details in crooked English) albeit one in a more speculative and opinionated way. This paper btw also confirms that A. muscaria is not as widely spread, then again Siberia is enormous and therefore its not very surprising to see pockets or large areas where it is common. In the Saar paper more on that on page two.
