Not one viral infection for over 10 years tells me l know what l am talking about and so do history books where they report garlic being used for the Plague.
Funny you should mention that. One of my students is studying the Black Plague period in history and her teacher asked me to teach some of the related science, so by coincidence I happen to have done some reading on the topic recently.
Over one third of the entire world population died from the plague in the late 1300's. If you exclude areas where the plague did not reach at that time, such as North and South America, and most of Africa, more than half of the population in plague areas died. So I'm guessing the garlic wasn't all that effective.
In modern times we treat the few cases of plague that arise with antibiotics. Untreated bubonic plague kills 40-60% of infected people. On the other hand, with antibiotics the mortality rate is 1-15% (depending on how early treatment is started). You're welcome to your medieval treatments. I'll take modern medicine, thanks.
The issue is not what any person chooses to do with his or her own body. I'm perfectly happy if someone wants to treat their bubonic plague or H1N1 or whatever with garlic, prayer, self-flagellation, or medication,
as long as they don't spread the disease to other people.
The issue is distinguishing between belief and scientific knowledge. Your
belief that garlic will cure H1N1 in less than 24 hours is not based in any scientific facts and contradicts a number of them. That's okay, you can
believe whatever you want, but it's belief, not knowledge. Passing on
belief as factual medical knowledge can be dangerous.
