The basic concept behind a pit or cone kiln is flame cap pyrolysis. This type of burning consumes all the volatile fractions as the gases pass through the layer of active flames on top. In doing so, they use up the oxygen at the surface of the fire and keep the charred material from burning all the way to ash. The most refined version of this type of kiln is the kon-tiki developed by Ithaka Institute and there is lots of great info on their site, including a how-to for a simple pit kiln.
My version is only novel because I dug it out of the top of a pile of dirt.

I witnessed this kind of bee keeping myself at some of the Orthodox monasteries in Turkey and Syria. Initially, I thought, "How brutal", but you can't argue with their results. By selecting only the healthiest colonies to go through the winter and be split the following year, they have some of the strongest breeding stock and healthiest hives I've ever seen, completely natural without any external inputs.

The phrasing sounds an awful lot like the warnings I've seen about solanum nigrum ("black nightshade") being poisonous under "some growing conditions" when it is perfectly safe if ripe and the actual issue is widespread confusion with other, actually poisonous, nightshades that happen to produce black fruit.
