You have a point. It probably wouldn't be the best choice if something better was available. If I was mowing lawns and trimming shrubbery in Kansas City and had a 7-11 store on every other corner I'd go with whatever I could quickly grab off the shelf.
But if I'm working twenty miles from the nearest paved road and fifty miles from the nearest town and I don't happen to have any medicine with me I'll probably grab some dirt. Clay is preferable.
You might prefer to suffer a bad case of the explosive trots. Most people wouldn't.
I would prefer to NOT catch something worse than explosive trots. I could tell you so much about what you might catch, but the worst risk is from any number of nematode parasites carried to the soil by woodland creatures scat.
No, you won't get bear hookworms, but you very well might have dog hookworm larvae wandering around in your body until the little worms discover you are not a dog. Ancylostoma caninum; look it up for yourself.
Toxoplasmosis comes to mind; transmitted by cats, people get it too.

Then there are all the tapeworm eggs that exist in the wild; almost all are waiting in the soil for some host to swallow. Most are very specific to a certain species, but that doesn't mean that they won't hatch in your guts and cause problems for a while. The eggs last for years, so don't presume that dirt not covered with turds are safe.
Ever hear of salmonella poisoning? Your explosive trots will only be accelerated by adding soil contaminated with bird droppings.
There are lots of other good reasons why eating dirt isn't a good idea.

BTW; This thread was started by a guy that wanted to come prepared into the work areas 50 miles from town. He asked for recommendations for what to bring. He did NOT ask for stupid home remedies.
I offered constructive advice; I only said that eating dirt was not a good idea. Eating dirt? Why didn't you just suggest that he goes down to the local sex shop and buy a nice big butt plug? That might stop him up better.
Don't be a #### and try talking down to me because you think I am some lawn monkey that never gets outside the city limits.
