One of the two most deadly mushrooms in the world. Neither is really hard to identify.
Milk Thistle extract is the most effective treatment but you need to take it soon after ingesting the shrooms and you probably ought to be under a doctor’s care as well.
Silibinin(a derivative of milk thistle) given intravenously is one of the more effective treatments for amanita poisoning. Other treatments are NAC, even intravenous penicillin...
Most important ..get thine “ass” to a doctor ASAP. At present the IV form of silibinin is available from FDA on a case by case emergency basis. (May have been approved ). It is available in certain European countries. The doctor has to get supplies from FDA approved suppliers.
Probably OK to use milk thistle products before silibinin treatment, but if not treated adequately liver failure could ensue...bottom line ..difficult to identify amanita mushrooms for many folks...why the H would anyone mess around? Reward for “self harvested” wild mushrooms hardly worth it. But then again people eat deer antler”velvet” cause they think it will give the eater great energy. Did see a case of someone getting fatal case of botulism from antler velvet. “Hold my beer” are famous last words.
