If you find yourself trapped outside- with no food for several days, you can eat the following.

1-- Clover leaves-- especially from those tiny clovers with the small yellow flowers that grow along sidewalks. They are high in vitamin C and even taste lemony.

2- Dandilion Leaf. High in absorbable Iron and Vitamins. The roots are especially great anti-viral, anti-bacterial agents.

3- Grass- is actually edible, provided it isn't sprayed with pesticides.

4- Pine Needles. Pine needles are high in vitamin C and were used centuries ago to prevent scurvy by pioneer men.

There are others like Horsetail Grass, Violas, Nasturtium, etc., - but these are the most common.
