This is what got me started a few months ago. I read an article from Dr. Mercola on foraging wild edibles. What a lot of people consider weeds are actually beneficial plants either as a food source or as an herbal medicine.
The arena of food foragers are an interesting collection of people. It brings together diverse backgrounds. Here you will find very conservative, religious people who do this for reasons of faith, and also liberal, environmental people who are concerned about natural means.
I have three main reasons this interests me. First of all, biblically, I think God put everything in place for man when he created the earth before he made man. Adam knew how to manage and garden in Eden. The whole creation is now under the curse of sin, but still much remains, and we as a human race have become divorced from the soil we came from, dust to dust. I could go on for pages on this topic, but will suffice it to say, it is there for the taking and we ought to and can use more of God's creation as he intended this for us.
Secondly, eating natural foraged food is way healthier, it has more vitamins, minerals, and phytochemicals than the sad substitutes grown commercially. The picture above is of lamb's quarters and it is a common "weed." It actually has more nutritious value than spinach, wow! It can be used in salads, soups or eaten just as spinach would be.
Third, we face disasters, rising food prices and the danger of the bottom falling out of the economy. If and when this happens there won't be food on the grocery shelf, so, then what? If we know where, what and how to forage the answer to eating vs. starving may be as nearby as some of the cracks in sidewalks or vacant lots. I am slowly steadily finding what I used to consider weeds and allowing them to grow in managed areas of my garden.
Yesterday's find was dock. I ate a soup made from potatoes, wild garlic, and dock. It was delicious, healthy and cost pennies. It looks like this and I bet you have some nearby.
This is a medicinal herb called broom weed. It is a great anti-viral and will help with a cold or flu better than an over the counter remedy. I found a few fields filled with the stuff, and it is easy to clip, dry or freeze and then use it to make a tea when a cold or flu comes along.
If you are interested I suggest one thing, do not rely on pictures from books or a website as many vairieties of plants look alike and some that are edible and fine, are close to some that will make you sick or even in extreme cases could poison you and even cause death.
I don't know much yet, but I found a wise older woman who has been doing this since a young girl and have learned from her. So if interested look online and then find some one near by who can help you with wildcrafting, foraging, or wild edibles.
