In the 19th Century, they didn't have many medicines to give asthma patients. Their primary medicine was cafeine to treat them and cause bronchodialation.
Then later, around 1950, people felt that asthma was fake. They felt it was largely a mental behavior from stress. You can imagine how foolish that was, for asthma has been documented since the ancient Egyptians.
I wrote about this once. See my sig and do a search. There are some common things in your home or common herbs you might find in meadows that in an emergency, like if we had a collapse of civilliation, that you use for asthma patients.
I think it was using a corncob pipe with a little Jimson weed, a tiny tiny bit, as it is very powerful.
I've written 1000 posts on prepping my sig, so it's hard to remember especially after 36 hours without sleep.
Yep that's it. See:
