I tried to grow licorice, the medicinal plant, from which the candy was based, last year. It is an outstanding anti-viral. It's possible that nearly everyone could use this. How many people don't get the flu or colds in the winter? I tried to grow it last year, but it died in the winter. I talked to others who tried to grow it, and theirs all died except for one guy, who made a rain shield for his and had it growing on a slope. My wife also mentioned that Thyme always dies for her in the winter, as it did for me. I also grew ginkgo seeds one year into plants, but since then, they haven't sprouted. I added ag lime to the soil to make it more alkaline and I added gravel throughout for drainage.
Then I made this rain shield. Yes, I know it looks trashy. The plexiglass was already that shape and someone was getting rid of it. I figured I would have a use for it some day and it seems that I have. I will take the rain shield off in March or April probably. I like rednecky projects like this and it seems to be doing ok so far:
