Many plants have curative properties so it's no wonder that herbal medicines have been used for hundreds of years. Before today, plant parts would be gathered and ground in a poultice to be administered to a person with an ailment. Now you can get herbal extracts in the form of syrups and capsules. There doesn't seem to be any harm in modernizing ancient natural medicine-but can we become sure that is entirely safe? The answer is that no, herbal supplements cannot be guaranteed to be safe for everybody.
