I love this topic! It was cool to read about ginger since it's so beneficial, I'll be using it more often (I think the same properties hold for turmeric).
I wanna do more research on this, maybe even hire a professional to teach me. But I hate books on "Folk medicine" which are abundant here in Russia, they have thousand of crazy recipes on 1 ailment, none of which seems to work.
Also I love using herbal medicine in form of Aromatherapy - using essential oils. For example I very easily cured candida and cystitis with Tea Tree oil
Ginger is one of my favorite herbs for sure. So many uses and it has a great spicy taste.
I can highly recommend the book I posted in my resources "The Little Herb Encylopedia" by Jack Ritchason. It talks about a brief history of each herb, the uses and benefits, etc.
