Can you eat the skin of a yam?

If you buy organic yams, you can eat the entire yam including the skin. If you buy traditionally prepared yams you should peel them because they are often treated with dye or wax. * i beg to differ. first conventially grown yams are most certenlly not treated with dyes or wax, secondly the use of many dyes and certainly wax is permitted in organic farming as it is a "natural" product (if you think you can sense some sarcasm you're not wrong) so if that whats worrying you eating organic is no solution.
