After searching a website, (see LINK) I noticed an article about Saba nuts containing cyclopropenoid fatty acids.  This tree was previously know as the Provision Tree.  We are starting to wonder if it should go into the compost bin.   What do you think?

So far, mine has not produced any fruit so I have not even tasted it. What do cyclo-whatsis do - not much info at fingertips on this one. If the nuts have been eaten for centuries then it's unlikely to be actually toxic.

Cyclopropenoid fatty acids are said to be carcinogenic and to cause liver damage.  

Wiki says: 

The presence of cyclopropenoid fatty acids in the nuts has been used to state that the nuts are not edible and not suitable for human consumption, despite the nut being eaten or used in medicine. Hanus et al. 2008 argue that CPFA are carcinogenicco-carcinogenic, and have medical and other effects on animals. According to them "CPFA in food is dangerous to human health". Out of 6 rats tested by Oliveira et al. 2000, 5 died after consuming the nuts. The surviving rat had enlarged organs including the stomach, liver, pancreas, kidneys, lungs and also had spleen atrophy. Research on the health effects of eating the nuts on humans is currently lacking. (

Apparently the raw nuts were fed to rats who died within a few days, that's OK if you need to do that.  My tree is a Pachira aquatica and I believe your tree Elaine, is Pachira Glabra.   The research is about 10 years old and I am unable to locate recent information about the saba nuts or Malabar Chestnuts or Guiana nut or French Peanut. 

The Pachira aquatica is named aquatica as it grows in coastal lowland regions and the nuts have been known to float for months down waterways.  The P.aquatica has red tinged flowers and the P.glabra, a white flower.  

Most research only mentions the effects of P.glabra so it is not known if the research only relates to that tree.  Maybe the answer is to boil the nut first and then roast before eating.   I can't be bothered with it, my pair of trees are not flowering to my knowledge.  

The info I posted was about the aquatica.  It is true for both trees Christa. 

Depends on which research you believe or read. One of the types was eaten as food by people in famine areas but maybe they boiled and roasted the nuts first. The info on which variety is very confusing regarding toxicity. 

Hmm, confusing. Before I ditch my tree I need to look into it a bit more. I have this expensive habit of buying fancy trees then getting impatient for them to produce fruit. My Saba has flowered twice (twice more than the Rollinia I have said good-bye to) and this summer could be its last if it doesn't perform.

I've requested Daleys let me know when their dwarf maccas come in.
