"Proper dosages should be used with herbal treatments just as with chemical treatments. The fact of the matter is that some plants most assuredly do have side effects and should be used with caution.
While many are safe in any amount, not all are. For example, foxglove, from which digitalis is derived, is a deadly toxin.
Belladonna & Monkshood are a couple of others.
I realize these are extreme examples, but they illustrate the point. A more commonly used plant is Blessed Thistle, which increases lactation. However, it can also cause vomiting and diarrhea in large doses.
The attitude of "since it's natural, it's got to be safe" is a dangerous one. So, by all means, if you're not familiar with a remedy, ask questions from someone who is!"
