I think this topic really just highlights the need for practical training in first aid and medical treatments. My son is highly allergic to all milk products so I have been practicing ingredient identification for a long time. At first we had EpiPens for him just in case. Found we didn’t need them eventually.
One of the First questions they ask at the ER; what medicines are you Allergic to?
btw, I’m not bashing homiopathic remedies, I just don’t know of one for infection in the lungs that works.
