There's a thread in the lycaeum that's relevent, I'll post the good parts:
" I guess there's cyanide in the outer shell of the HBWR seed. The problem with this is that cyanide is polar like LSA and iso-LSA. So the standard non-polar/polar extraction winds up leaving cyanide in the end product. Is there another step one can take to eliminate the cyanide without destroying the desired amine's? "

They do contain other substances that makes you feel nausea, they are; cyanogenic glycosides.
cyanogenic glycosides will be extracted with a nonpolar solvent.
The first 4 letters in cyanogenic glycosides reminds us all of another mentioned substance, lets not create another myth.
Sources for above facts are: Lycaeum.org and Erowid.com"
"To clarify, HBWR seeds do not contain HCN (Hydrogen Cyanide, Cyanide) themselves. The cyanogenic glycosides which are concentraded mostly in the coating of the seeds (and in some cases within the seeds) are boken down in the body and HCN is released. That is what causes the nausea, and if you eat enough seeds without removing the coating, painful death."
"So, if one removes the coating and maybe even the shell, nausea can be almost completely avoided. Interesting.
I always thought that the removing of the seed coat in order to obviate nausea was just a silly myth, possibly arising from real danger of ingesting fungicide-coated MG seeds. Huh."
"Thank you Matthew for telling us this.
I checked it myself on the www... Cyanogenic Glycosides does break down to Cyanide in the body.
I wonder why I havent seen this fact before. Despite reading numerous trip reports and facts on HBWS. We cant be as false as those people running the war on drugs (they are in some cases keeping out facts about drugs). We, as a community, have to display all the facts.

"Lima and kidney beans are toxic uncooked. Both beans contain cyanide producing compounds (cyanogenic glycosides), which can be destroyed by adequate cooking. Small amounts of cyanogenic glycosides will be detoxified by the liver. Cyanogenic glycosides are also found in fruit pits millet, sprouts, yams, maize, chick peas, and cassava root."
Today is opposites day. Everything I say, I mean the opposite.
