Tant, rather a lot of the info passed on this and other forums could be taken in the wrong way by people (and kids) reading it...all the fire lighting threads, the trapping/hunting threads etc all carry the risk of "give it a go, I read it on the internet".
I did state that the "conkers" had to be leached and roasted, which does kill off the toxins and renders them safe to eat.
I know they were used as famine foods and they are quite safe to eat then. Wood Sorel and other plants are also toxic in large quantities but you'll find people saying they are fine to eat. People talk about how nice the fungus commonly known as "Ink Caps", are to eat but few mention that they become quite highly toxic if eaten with alcohol.
I don't feel a need to freak about Horse Chestnuts and stand firmly by what I have said in my below posts. If you choose not to eat them then that's entirely up to you mate. A friendly clarification on the need to prepare them properly would have surficed rather than a scarey warning that they are poisonous but hey, no skin off my nose if nobody else in the world eats them....personally if I was living off the land then they would definately be part of my diet.
Cheers,
Bam.
