Are Herbal remedies tested and licensed the same way as medicines?
Herbal remedies are tested by the food standards agency to make sure there safe to consume but most are sold as food supplements not medicines so they don’t require licensing and may or may not work. If your thinking of using them the best place for a balanced review is probably the Wikipedia, they usually reference the positive and negative studies, try make your own mind up from that. Health stores usually just tell you about the possible benefits to get the sales and not how many studies came up as inconclusive, that being said some certainly do work.
