I have also been using liguid Enchinacia and goldenseal for over 20 years. I do not take it as directed. When you first feel the signs of a cold coming on, itchy nose, scratchy ittitated throat (before you actually get sick) I take 2 dropperfuls in the morning, 2 at lunch and 2 at dinner. 9 times out of 10 I will not need to take anything else and all symptons are gone. I have had maybe 2 colds come on in the last 20 years. I have been using this to stop colds, even though people tell me it doesn't work. It work's for me. I had a Chinese naturalist tell me to use it this way many years ago. She did say not to take it on a daily basis or it wouldn't work as a cure. You can only use it for 3 days straigt as a cure. I am not a doc but it works for me. The key is, to have it in the house all the time so when you feel it coming on, you get to it quickly. If you wait 24 hrs, its to late.
