Rei shi on November 14, 2013:

Recently i ate 2 handfuls of steam champignons, they had actually gone rather dark. The next day my urine was really acidic (I test it every morning) and my mood subsequently awful. I additionally didn't sleep well through the night; wake up up approximately 3am, something the happens as soon as the liver / gallbladder is the end of whack. The liver processes toxins, for this reason it can well be related to the mushrooms ns ate. I had brushed off many of the dark areas though.

Because the mushroom body has actually such a moist and also soft structure, ns think it's really hospitable for new invaders (other fungi, moulds, yeasts, parasites?), and also easy for them to enter. ~ the mushroom has fulfilled its objective of dropping spores, it's discarded by the mycelium network, therefore it would be logical that various other organisms will come in to compost it. Yet our body shouldn't be composted yet! (Which is what happens as soon as we're infested through candida & other anaerobic opportunistic organisms).

Good reasons to be really careful around this issue. I say litter away if also a little suspicious.

Milesy on November 13, 2013:

I'm tho worried about JJ, it's put me appropriate off mine 2 mainly old slimy mushrooms, that's for sure.

I love mine mushrooms, i cooked some buttered mushrooms for dinner tonight, but as i was quick on fresh ones i ventured deep into my fridge and also going some older ones in a bag. I can not say precisely how old lock were but they might have even been a month old. They were in a document bag most were quite dried up however some were a slight little bit slimy but as i was going to cook them well I assumed I would be ok. Well the mushrooms are having the critical laugh currently as I have been glued to the toilet for 12 hrs now! Don't eat suspect mushrooms, it's no worth it!

I chicked out any type of obviously negative ones and washed the others till the slimey feeling had actually gone. Gonna chef them because that a good long time through butter/spread and also at a high temperature so hopefully that will ward off any likely bugs?
