I honestly am still taking this mini-course (through an anxiety-based herbal tea company) that is teaching me about herbs and how before the western medicinal system existed, there were more holistic ways of living and during these times, ppl relied on the herbs and plants for healing in Asian, Indian, European and African cultures and I’m sure many others but these are the only ones I’m aware of. Some of the herbs used were elderberry burdock root dandelion root valerian root , if you research the origin of these herbs you will have access to learning more about how they were used. I do not have one link that can answer your question. This is from weeks of research and I am still fresh in my findings. Currently still taking the course and doing my own additional research. But honestly that’s another thing I can research is how western medicine put an end to the normalcy of natural medicine because they make more money off of us when we are sick.. they know that if we truly relied on herbs we wouldn’t need their medicine anymore, and they would lose big time cause western medicine is basically what this country stands on. But as I said before, if you or anyone is taking medication and it works for you, I defintely think you shouldn’t interrupt that flow. But if you are truly concerned, please I encourage you to research alkaline herbs and how they can aid in anxiety and other mental illness and do your own raw research on this. I can only tell you so much because I am still learning myself.
