Swine Flu Cure Used During 1918 Flu Pandemic

How did people in the past, especially immortals, survive the many diseases and plagues of our past?

Perhaps there were simpler treatments and "cures" during those simpler times; such as this old remedy from 1918 for treating the devastating pandemic of that time.

It still amazes me how many people of our past, had remedies for just about every disease; and many of these remedies had a record of success.

The stories my 2,800 year old friend told me about his use of oregano and garlic to combat much of the common infections that plague the masses in our past; are priceless.
