I have always believed that nature can do or supply everything the body needs to not only survive but thrive. I have used herbs all my adult life hard to find good outlets to get quality herbs. So far all my herbs are doing what i need in varying degrees. I believe you need to allow the herb some time and the body to acclimate to the herb. I got in to herbs because drugs are chemical and can do more harm than good and you will eventually pay for the magic pill, so to speak. I believe the body can heal itself if you stop the thing that made it ill and give it what it needs to heal herbs do that and more.
