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
