Finally found this article, heard from TV programme before but forgot is use garlic or onions... share with you all !!

周我有两个午餐会不得不取消,本周也是难以确定好几个午餐会是否要举行,因为很多人生病(不一定是甲流)。 这次的流感的确给人们的生活带来很多麻烦和困扰
一个加拿大朋友把下面这封邮件发给我和一些朋友。我把它翻译出来送给大家,希望对你有所帮助,希望大家健康 平安不要生病。其中的一些东西与我们中医和中华饮食有关联。
In 1919. When the flu killed 40 million people, there was this doctor that visited the many farmers to see if he could help them combat the flu. Many of the farmers and their family had contracted it, and many died.
年。当流感造成了四千万人死亡时,有一位医生到各地农场去探视,看是否可以帮助人们战胜流感。很多农民和他 们家庭感染了流感,很多人因此而死亡。
The doctor came upon this one farmer, and to his surprise, everyone was very healthy.
When the doctor asked what the farmer was doing that was different, the wife replied that she had placed an unpeeled onion in a dish in the rooms of the home (probably only two rooms back then).
医生询问这家的做法与其他人家有何不同,这家的妻子说她在家里的每一个房间(那时大概也就是两间吧)里放置 了一颗没有剥皮的洋葱。
The doctor couldn't believe it, and asked if he could have one of the onions, and place it under the microscope.
She gave him one, and when he did this, he did find the flu virus in the onion.
It obviously absorbed the bacteria, therefore keeping the family healthy.
Now, I heard this story from my hairdresser in Arizona.

She said that several years ago, many of her employees were coming down with the flu, and so were many of her customers.
The next year, she placed several bowls with onions around in her shop. To her surprise, none of her staff got sick. It must work . . .
次年,她在她的理发店里放了几个果盘,里面放了一些洋葱。令她吃惊的是,她的员工没有一个生病的。看来洋葱 真的起作用Ö
(And no, she is not in the onion business.)
The moral of the story is, buy some onions and place them in bowls around your home.

If you work at a desk, place one or two in your office, or under your desk, or even on top somewhere.
Try it and see what happens.
试试看效果怎么样。We did it last year, and we never got the flu.
If this helps you and your loved ones from getting sick, all the better.

If you do get the flu, it just might be a mild case.
Whatever, what have you to lose?

Just a few bucks on onions!
Now there is a P. S. to this for I sent it to a friend in Oregon who regularly contributes material to me on health issues.
She replied with this most interesting experience about onions:
I dont't know about the farmerís story, but I do know that I contracted pneumonia, and needless to say I was very ill..

I came across an article that said to cut both ends off an onion, put one end on a fork, and then place the forked end into an empty jar, placing the jar next to the sick patient at night.
我读到一篇文章,建议把洋葱的两头切掉,插在叉子上,然后把叉子放在花瓶里,晚上放在病人身旁 。
It said the onion would be black in the morning from the germs.
Sure enough, it happened just like that.
The onion was a mess, and I began to feel better.
Another thing I read in the article was that onions and garlic placed around the room saved many from the black plague years ago.

They have powerful antibacterial, antiseptic properties.
