Some mammals, like mice, can produce their own vitamin C inside their bodies. Unfortunately, human beings are not on that list of critters. We need vitamin C, which we get from outside sources, because it performs such an important variety of functions in the body, including increasing immune system health, tissue repair, and iron absorption. Without enough vitamin C we can develop symptoms of scurvy, such as fatigue, weakness, capillary fragility, and gum disease.

Fortunately, if you ever get stuck somewhere away from your normal food supply, there are several great sources of vitamin C in winter edible plants.

Perhaps it is the way that this survival kit hangs from your backpack, ready to be grabbed at a moment’s notice. Or maybe it’s its size and shape. Either way, the Rocky S2V Survival Grenade is a novel approach to survival kits. It’s not just another sardine can full of matches and fish hooks.
