Queen Anne's lace or Wild Carrot (Daucus carota) is an herb that grows abundantly in the wild and has a large range. It is a very useful herb with many good properties and can be eaten as a food. The root is a small carrot. Storebought carrots are a subspecies of this plant. One of the properties I keep seeing listed for it online is that it is an MAOi. I'm curious is this could be another new useful maoi. I have some growing in my backyard and may try it soon. Must just make sure it is not yarrow which is a very similar looking herb.

The only Overdose information I could find is that it can cause symptoms of skin irritation/rash when triggered by light exposure. I can't find any info of anyone ever dying from it or any other OD effects.

The only dangerous look-alike (vaguely) is Water Hemlock.

This is very common where I live. I have to say that I've never had any luck eating it because the the root was always too woody. Maybe I wasn't cooking it right (or at all, come to think of it). It would be neat if it turned out to be a good MAOI source.

Wouldnt the seed be the bit to give the most attention? That seems to be the part most used medicinally to prevent pregnancy, as a restorative tonic, etc.
If landrace Daucus carota seed proves to be at all useful as an MAOI I wonder if domesticated types would work the same, you can just plant a carrot and a few months later harvest the seed.

Fool's Parsley is another look a-like:

I've also recently read Gentian is an maoi as well. Will have to look into these more.
