Comments: This is that obnoxious weed whose seeds are incredibly painful to step on, get tracked into your carpet, puncture your bicycle tires, and have to be pulled out of your pets' paws. The seed pod grows 4 "bullheads" in a circle (see photo), when mature it breaks up into 4 separate instruments of torture. The plant is naturalized, originally from the Mediterranean. It is a pest plant wherever it resides in the US. In Europe the plant has been used in folk medicine throughout history, treating such wide-ranging conditions as headache, nervous disorders, constipation, and sexual dysfunction. In China, it has been touted for use in liver, kidney, urinary, and cardiovascular remedies.

I'll tell you something more about them too. When I was a kid in Texas I learned that when you go running out into the yard barefooted they simply will not stick you......till you are in the middle of the yard.....then you can not take a step back towards the house without getting a foot full. You just can't find a place to step lol. really.
There seem to be but three ways for a nation to acquire wealth. The first is by war, as the Romans did, in plundering their neighbors. This is robbery. The second by commerce, which is generally cheating. The third is by agriculture, the only honest way, wherein man receives a real increase of the seed thrown into the ground, in a kind of continual miracle. Ben Franklin
