I like that you're trying everything that we think of as 'famine food' for edibility, etc., and I freely admit that many of them I'm happy just to add to the seasonal foraging, but conkers...those I use for washing hand made, embroidered, hand made lace, linens. I've never made the varicose vein treatment, thankfully not in need, but I watch James Wong's programme with interest. Archaeobotany and Ethnobotany are of great interest

No I do understand that.
But that's quite a subjective point of view isn't it? One mans meat etc.
Some may think its strange to experiment with Acorns for Flour - Other may not.
Most of the wild food forums & fb pages I've seen all state openly that Arum Maculatum is just a black & white closed book example of a Toxic plant - yet there is a way to process it.
I'm not looking to poison myself , I'd rather do adequate research and listen to the other perspective of others to see if there is more information below the surface of what is commonly believed.
I posted the original question as I'm sure I have seen a post somewhere ( must be elsewhere ) of someone turning Conkers into Coffee.
And since posting I found this article in PFAF which I should have checked first.
"
The roasted seed is used as a coffee substitute[2, 7]. Seed - cooked. It can be dried, ground into a powder and used as a gruel[7, 46, 55, 61]. The seed is quite large, about 3cm in diameter, and is easily harvested. It is usually produced in abundance in Britain. Unfortunately the seed is also rich in saponins, these must be removed before it can be used as a food and this process also removes many of the minerals and vitamins, leaving behind mainly starch. See also the notes above on toxicity. The seed contains up to 40% water, 8 - 11% protein and 8 - 26% toxic saponins[218]. The following notes apply to A. californica, but are probably also relevant here:- The seed needs to be leached of toxins before it becomes safe to eat - the Indians would do this by slow-roasting the nuts (which would have rendered the saponins harmless) and then cutting them into thin slices, putting them into a cloth bag and rinsing them in a stream for 2 - 5 days[213].

So whilst i can accept it raises eyebrows and concern there would seem to be adequate grounds for me to explore the possibility where others have clearly gone already.
