Laurel – Love the smell, but is it really bad for you?

I once trimmed a long laurel hedge, reaching the tops from the back of the truck, standing on piles of Laurel. By the end of the day i was felling sick with a banging headache. It disappeared in the evening but first thing in the morning after getting back into the back of the truck it came straight back.:thumbdown:

Not recommended.

 

I was exactly like that after chipping a load of it one day, felt really sick and thumping headache, not good. Still rather chip that than London Plane though! :stoned:

There is a classic experiment I remember at school that demonstrates the potency within a confined space of the volatile cyanide produced by crushed Cherry Laurel leaves.

 

EiC July 2008 - Feature - Exhibition chemistry: Toxic Hydrogen Cyanide

 

I think we used ladybirds IIRC.

 

Note "The UK workplace exposure limit for HCN (short-term, ie 15 minute exposure) is 10 ppm (11 mg m-3)." Also note that I have no idea as to the concentration within a truck full of chip! :D

 

Cyanide screws with enzymes and results in cell death - so perhaps sucking in great lungfuls of the aroma ain't such a good plan.
