To be taken at first sight of getting a cold

Posted by Reviewer2507624 on Jan 02, 2012

This health supplement has a mild beneficial effect on dealing with the first symptoms of colds. For lingering colds/flu, rather take the Zong Gan Ling supplement.

I tried this supplement when I was coming down with a very sore throat. The next day, after just 2 supplements, I no longer felt ill. I have since used it every time I feel a cold coming on and I am happy to say I have not had a cold in 2 years. I also used it when flying to and from Europe and it is the first time I did not get sick after traveling.

With this, the beginning of the flu sickness is reduced to a mild one.
