Neem Oil impact on final Product

Does anyone know if neem oil can have a negative impact on distillate? I’m trying to come up with a list of things to ask growers when buying trim. I haven’t had any issues in my few years of processing to distillate but it was a problem when I was running BHO. Just wanted to see if anyone had ran into a problem with neem oil and what those problems were/are?

Any info help.


@weave If the neem oil has the molecule Azadirachtin in it, it could potentially have a negative impact.


What sort of negative impact?

Azadirachtin is a terpene.
must mean it’s good for you…

certainly means that it will come along for the ride in your extraction.

But I would think it’d be pull during the terpene fraction, no?

no idea. it’s a big one. so there will probably be some in your boiling flask after devol.

it should probably travel with the heads. but I’m without data & guessing wildly

@drjackhughes is the first one that springs to mind who might have that data.


In a couple SPD runs we saw a milky, oily fraction that contaminated heads fractions in the first pass. We were told it was neem oil on the Facebook advanced distillation group. Never saw it again.

The connection between Cannabinoid hyperemesis and Azadiractin seems pretty tenuous to me.

not “out of the question”, but certainly nothing that qualifies as “clinical data”.

I’ve got a kid who suffers from it on my team.
Not willing to use him as a guinea pig at the moment.
Mainly because is mom would kill me :wink:
