But you must realize, legally, employees of stores are not allowed to tell more than the label does. German studies have shown that, when taken at the onset of colds or flu, it boosts the immune system by enhancing the activity of white blood cells, that during such a time it's wise to take as much as 1,000 milligrams 3 times a day, and that, after taking it for 2 weeks, it's best to discontinue use for a few days. Too bad our current laws don't allow manufacturers to say so. 10 Many of the herb and supplement manufacturers in the health food industry have gone several steps further in their commitment to the highest quality and purest supplements possible.

The whole premise of there being only one or two things that make an herb work or make a person sick is the basic weakness in the medical profession. Synergy happens and the combination is best left to the plants' wisdom without interference by arrogant humans who think they know better than their Creator.

If you've never been in a health food store before, you may be surprised at how many different forms the same herb can come in. Tea is the most common and oldest form of herbal therapy.
