This information on black walnut is harmful. The fruits contain a toxic substance called jugalone which cannot be consumed. Every notice a black walnut tree and notice how there are no other plants in a circle around the trunk? That’s because of the jugalone. Have you consumed any without any side effects because that’s interesting considering the number of black walnut trees I have on my property. EDIT: I’m finding conflicting information online so I’m not sure. Apparently jugalone is poisonous to humans but I’m also seeing lots of black walnut recipes.

Juglone is toxic to most plant species but AFAIK it is harmless to mammals.

  Horses get sick a lot from eating black walnuts.

    The husk on the outside of the walnut contains most of the jugalone. That's the green-to-black part on the outside of the fruit. If you've bought whole walnuts (dry, brown, wrinkly), but never seen them in the wild, you've never seen this part. The horses and pigs get sick because they only eat the husk, they can't crack the shell to get at the nutritious part. The meat inside of the shell is safe.

Do you have any references for this? Black Walnut produce more jugalone than other walnuts but "Most members of the Walnut family (Juglandaceae) produce a chemical called "juglone" (5 hydroxy-alphanapthoquinone) which occurs naturally in all parts of these plants." [1] I have no reference to juglone as being toxic humans despite many references to its toxicity to other plants. I personally haven't consumed much 'cause they're a hassle to prepare but other comment to my post was from a person who with no apparent effects. And I've eaten lots of commercial walnuts, which supposedly also contain jugalone And, there's toxicity to horses from juglone and to dog something else from but nothing related to humans mentioned here or anywhere I can find. http://www.omafra.gov.on.ca/english/crops/facts/info_walnut_toxicity.htm http://www.omafra.gov.on.ca/english/crops/facts/info_walnut_...

You're saying it's best to avoid a gathering of the jugalone?
