Rei shi on November 14, 2013:

Recently I ate 2 handfuls of steamed champignons, they had gone fairly dark. The following day my urine was extremely acidic (I test it every morning) and also my mood ultimately awful. I also didn't sleep well through the night; woke up roughly 3am, somepoint that happens when the liver / gallbladder is out of whack. The liver procedures toxins, so it might well be concerned the mushrooms I ate. I had actually brumelted off the majority of of the dark locations though.

Due to the fact that the mushroom body has such a moist and also soft framework, I think it's exceptionally hospitable for new invaders (other fungi, moulds, yeasts, parasites?), and easy for them to enter. After the mushroom has actually fulfilled its purpose of dropping spores, it's discarded by the mycelium netjob-related, so it would certainly be logical that other organisms will certainly come in to comarticle it. But our bodies shouldn't be composted yet! (Which is what happens as soon as we're infested through candida & various other anaerobic opportunistic organisms).

Good factors to be exceptionally mindful about this concern. I say throw away if also a little bit suspicious.

Milesy on November 13, 2013:

I'm still worried around JJ, it's put me appropriate off my 2 week old slimy mushrooms, that's for certain.
