A number of studies have shown that certain herbs may help people with conditions ranging from headaches to high cholesterol. But if you decide you want to give herbal medicine a try, you face a formidable obstacle. There is no guarantee that the pills are what they say they are, and in most cases no one really knows what will happen if you take them.
You may have no way to be sure…whether a plant’s active ingredients actually ended up in the herbal pills you buy; whether a supplement’s ingredients are in a form your body can use; whether the dosage makes any sense; what else is in the pills; whether the pills are safe; and whether the next bottle of those same pills will have the same ingredients.
The manufacturer may not know this information either because they are not required to do the testing or quality control that are standard protocol for regular drugs.
