As I’ve mentioned before I prefer to take herbal supplements and remedies in alcohol-free extract form that’s alcohol free, for rapid absorption and ease of digestion. Here’s the link to the Vitamin Shoppe line of extracts which are great.
I think an interesting thing to point out is that generations and generations did this trial and error Research before us to figure out what plants work for what conditions. There is more to figure out of course but one doesn’t have to start over at zero. There is multicultural documentation of plant remedies. And that’s what modern medicine is at its core — It just turned down a dark alley in my opinion.
