Doesn't appear so. See link where it says this "Root - cooked. A famine food used when all else fails" "Famine food" is always a key phrase meaning it doesn't taste good, has limited (if any) nutritional value, but it won't kill 'ya if you eat it! FataMorgana Here is a link that might be useful: Pfaf.org - hedychium coronarium

I forgotten to mention that the height of this plant is about or less than 12 inches. I also thought it was "bottle" brush ginger, but seeing the plant images compared to my plant seems very different. The Hedychium coccineum looks huge! Also the form of the leaves compare to Hedychium coccineum does not look alike. I love the mosses and the young Psilotum nudum or moa growing in the pot. I decided to divide this plant into four or five segments. It's a bit root bound and will be planted in a new pot.
