7. Safe: Wolffia globosa
These tiny little plants that cover the surface of ponds, and sometimes decorative fish tanks, are great if you ever find yourself starving near a body of water. This plant that is the smallest in the world actually has an incredible nutritional value.
If you can find a way to cook it first, some people say it tastes like sweet cabbage. It also doesn’t hurt that it’s rich in vitamins A, B2, B6, C, and nicotinic acid, and it contains only 5% fat.
8. Safe: Aloe vera
If you haven’t been living under a rock, you probably know all of the great uses for aloe vera. It can help with a multitude of skin irritations and diseases, while at the same time having antioxidant and antibacterial properties. It can also heal burns!
In medicine it is called a “wonder flower” and you can put it in food (great way to avoid severe dehydration in the wild), cosmetic masks for the face and hair, and use it as an herbal remedy.
