As I
write this we are still in the grip of winter...it is cold. But I know that by
the time you read this, Spring will be here and plants will be emerging from
dormancy. This is the time when many people follow the examples of the pioneers
before us and go out to collect wild foods and herbs as they become available.
There is a vast selection of edible
plants available in the wild. Some are the wild relatives of the herbs we grow
in the garden such as mint and watercress. Others are plants that are used as
vegetables like lambsquarters and stinging nettles; these are known as potherbs.
In addition there are plants used for a variety of foods – young dandelion
leaves for salads, wild leeks for pickles, and elderflowers for fritters are
only a few of the many choices.
As well as those we use for meals, there is another vast amount of wild
plants we may collect for medicinal uses such as yarrow flowers and red clover
or, to get on-the-spot relief from bites or stings, such as plantain leaves or
dock.
If we are going to use wild plants as food or medication we have to be
responsible for ourselves. This means that.....
1. We must be certain that we can identify a plant correctly in all stages of
its growth. For example fiddleheads are the young shoots of the Ostrich fern
found growing in clumps in the marsh. They are delicious and generally
considered safe. But to the uninitiated the young shoots of bracken could look
very much the same. However the bracken shoots grow singly and are spread out
over a dry area. Bracken has been found to be carcinogenic and should not be
eaten. (The Ostrich Ferns are particularly easy to recognize as they have spore
bearing dark brown fronds rising out of the clump; the bracken does not.)
2. We must collect plants only where there is no danger of contamination by
insecticides, fertilizers or traffic fumes. Though thorough washing of the
plants is necessary, this will not always get rid of contaminants so the area
where the plants are collected should be studied carefully. Watercress is a good
example and it should not be collected from areas where there is danger of a
runoff from farmland.
3. The plant itself must be thoroughly researched; some parts maybe toxic
while others are not. For instance, most people know that while we can enjoy
young rhubarb stalks the mature leaves are poisonous. Potatoes which have been
left in the light and turned green also have toxic properties and the green part
should be removed before they are used.
I am grateful to Colleen Cooney who brought this to my attention in her
letter in the November/December issue of Natural Life, when she wrote
about elder flowers and that she became ill after eating them. We will all have
different reactions to foods and probably have to go carefully with new foods
until we know how our bodies respond. We all have friends who cannot eat
mushrooms, shellfish or in some cases even nuts and they avoid them in their
diet. With wild plants and herbs we need to be especially aware; many wild
plants, though not toxic, do have purgative effects which may cause discomfort.
I have a friend who loves her spring salad of violet leaves even though she
knows that she may well have some problems if she over-indulges.
Books may not always help...out of eight books on collecting and cooking wild
plants three warned of the purgative properties of the elder stems; the others,
more cooking oriented, made no mention of it. Herbal books also do not mention
any problems. In fact all parts of the elder plant can be used medicinally if
prepared properly. Of course great care must be taken in the preparation of any
new food and any instructions closely followed. There are a few general guides.
It is best to use plants fresh or dried but never wilted, it seems that as they
wilt there are chemical changes which could cause problems. Also if any recipe
says boil and change the water once or even up to three times be sure to follow
the instructions. I once gave myself a very anxious time when I ate a marsh
marigold bud before it was cooked when I was making capers; the texture was
delicious but the experiment will not be repeated!
To sum up. It is great fun collecting wild plants and herbs for food and
perfectly safe if some rules are followed.
1. Know your plants and if in doubt ask an expert.
2. Check the area where you are collecting for contaminants
3. Read about the plant in more than one book and follow the instructions
for preparation and cooking carefully.
4. Start with small amounts and watch for reactions in your own body before
eating large quantities.
So on to Summer and good wishes for good foraging as well as good gardening.
