FOOD FOREST MEDICINE Monograph #10: Wild Leeks

Common Name:

Wild Leeks (Ramps)


Latin Name: Allium tricoccum




Brief Description:
Wild leeks are native to the eastern North American mountains. They can be found growing in patches in rich, moist, deciduous forests and bottoms from as far north as Canada, west to Missouri and Minnesota, and south to North Carolina and Tennessee. In early spring, ramps send up smooth, broad, lily-of-the-valley-like leaves that disappear by summer before the white flowers appear. The bulbs have the pleasant taste of sweet spring onions with a strong garlic-like aroma.
Caution: Lily of the valley is a poisonous look alike. The easiest way to make sure they are wild leeks is to crush the leaves and take a sniff. If it smells like garlic it is not Lily of the Valley.
Parts Used/Edible Uses:
The leaves and bulbs are edible.
Medicinal Uses:
Ramps first became a marketable commodity in 1966, when the USDA began to promote wild crafting as a means of improving the local economies of south-central Appalachia. The area is still known today for its focus on traditional uses of plant foods and medicines (Cavender 2006). Wild leeks have a variety of traditional medical uses and have properties that lend them to potentially be developed into modern medicines to treat more serious diseases. As some of the first greens to emerge in the spring, wild leeks are an integral part of a vitamin and mineral tonic many use to promote health after the long winter months (Davis and Greenfield 2002). They have also been used as a preventative measure against colds and the flu, as well as for part of a cure for scurvy (Legault 2003; Feiring 2006). For these uses, the plant is best consumed whole, and is eaten either raw or fried. Also, the plant is used as a purging tool for disease prevention and treatment to clean both the blood and the digestive system (Cavender 2006). Some evidence points toward the ability of wild leeks to lower cholesterol and lipid counts in the blood (Cavender 2006).
Body System’s Treated:
Cardiovascular, Digestive
Harvesting Notes:
Over-harvesting has become a concern for many conservationists. You should be careful on the amount of leeks you intend on harvesting in one area. Small patches of leeks can be over-harvested leaving nothing for the upcoming season.
Depending on what you plan on using the leeks for, you might just harvest the leaves, leaving the bulb in the ground. Ideally the leaves should be around 6 inches long and 2 inches wide, for the mildest flavor.
Methods for harvest include digging the whole patch, harvesting a portion of a patch, or thinning out and harvesting just the largest plants. Do not harvest plants until they have filled the site, have large bulbs, and have flowered.
If whole plots are harvested at one time, it is recommended to have enough plots to allow for a 5 to 7 year rotation. That is, to have continuous harvest year after year, harvest only one-fifth or one-seventh of your production area each year. When harvesting a portion of a plot, no more than 15% of the ramps should be removed. If the thinning method is used, great care should be taken not to damage plants that are not harvested. Based on research done on wild population, harvests should be limited to 5 to 10% of the plants in each plot.
If harvesting bulbs from the wild make sure to cover the hole that is left with leaves from the forest floor. Exposed soil leaves an opening for invasive species like garlic mustard to root and take over.
Safety/Cautions/Interactions:
None known.

FOOD FOREST MEDICINE Monograph #9: Sugar Maple

Common Name:

Sugar Maple


Latin Name: Acer saccharum




Brief Description:
Sugar maple is a deciduous tree, normally growing to heights of 12-24m. The leaves can reach up to 20cm long and wide, and have 5 palmate lobes. In spring/summer, this tree will be filled with green leaves but towards fall, it will start to color unevenly. It may be distinguished in the wintertime by its sharply pointed, multi-scaled, narrowly conical buds, which are pale brown The end bud is about ¼ inch long, with side buds being smaller. Sugar maple branches are opposite.
Parts Used:
Inner bark, leaves, sap, seed, seedlings
Edible Uses:
Syrup!!! (pancakes, French toast, sweetener for tea...) Some First Nations people combined maple sugar with powdered sweet corn as an energy food for long journeys, or as the base for a sauce used in roast venison preparations. Sap can also be converted into vinegar (7).
Seedlings gathered in early April could also be washed, chopped and added to salads or soups (7).
Medicinal Uses:
Traditionally used in treatment of coughs and diarrhoea. Sap is used as cough syrup. Boiled leaves can be applied topically as a poultice for boils. Decoction of leaves and bark in the treatment of sore eyes. A decoction of leaves/bark is also thought to strengthen the liver and kidneys. Generally considered a tonic (for liver, kidney, spleen and nerves)(6).
Maple sap is often high in oligosaccharides (biochemically, a small sized carbohydrate consisting of 3-9 simple sugars/monosaccharides). It has been shown that oligosaccharides serve as pre-biotic nutrients. Pre-biotic oligosaccharides have been shown to feed beneficial intestinal micro-flora, while suppressing other intestinal bacteria. Some studies have shown that maple sap may serve as a good medium for the growth and production of probiotic bacteria for supplemental use in humans. Thus, maple sap may be a good option for non-dairy source probiotic drinks. However, some people may have difficulty digesting oligosaccharides, making the consumption of pre-biotic rich foods, such as maple sap, problematic in these populations(8,9).
Maple sap and syrup contain antioxidant properties. Syrup has more anti-oxidant capacity than the sap. Maple syrup has a similar ORAC value (a measure of anti-oxidant value) as strawberry and orange juices. Some maple syrup extracts have also shown in vitro anti cancer action (4).
Maple sap is said to contain Abscisic acid. Studies using mouse models have shown promise for maple sap, via Abscisic acid, to have potent anti diabetic effects in mice along with anti-inflammatory action in inflammatory bowel disease and atherosclerosis. This research is preliminary and requires further research.
Body System’s Treated:
Respiratory, nervous system,liver, kidneys, spleen, digestive
Other Uses:
Fuel, Potash, preservative, wood
Harvesting Notes:
Maple trees should be at least 1 foot in diameter (about 40 years old) before they can be tapped, and no tree should have more than 3 taps. Place taps near bottom of the tree slanting upwards to allow sap to slowly drain into containers. Make sure containers have lids so rain water cannot dilute the sap. Look to harvest in late winter/early spring. A large maple will yield 3-6pounds of sap annually.
Safety/Cautions/Interactions:
None known

Starting Native Plants From Seed Indoors

The icy grip of February is still upon us and spring seems very far away.  You're probably itching to open up your seed packs and start those tomatoes or peppers but it might be a bit early.

There are seeds that can be started right now however.


Assortment of Carolinian seeds.


Seeds from most annual plants can be sown in spring and will grow no problem but many native plants seeds start off dormant and require a period of stratification to break this dormancy before the seed can grow.


Different seeds require different types of stratification and it's sometimes a matter of trial and error before you can determine which stratification method will work.  Mimicking the natural cycle of a seed in its native environment will usually do the trick; and most native seeds will have documented stratification info somewhere.

The most common type of stratification required is where the seed is moist and cool for a period of time but sometimes a warm moist period or combinations of the two may be needed as well.

Stratification can be done naturally by planting the seed outside in the fall and letting the seeds go through their natural cycle to break the dormancy or it can be mimicked indoors.  This method is probably the simplest and least labour intensive.


Stratifying indoors can be done using a variety of methods but one method that is quite successful is the 'baggie method'.

Nodding onion ready for the fridge.

The baggie method involves using a seal-able plastic bag and moist coffee filters/paper towels/cotton balls.  Cut the coffee filter in half an fold in half a couple times.  Dip the coffee filter in water and then squeeze out the excess water until the filter is damp but not soaking wet.  Open up the coffee filter and place your seeds inside then close the filter. Place the filter inside the bag and seal it up.  Label your bag with the name of the plant and the stratification details. (ie. date put into fridge and date to take out of fridge).


If the seeds require cold stratification place them in the fridge for the prescribed amount of time.  Its a good idea to periodically check your seeds just in case they have germinated a bit early.

Some seeds will require only a few weeks in the fridge whereas others may require months.  It is a good idea to plan ahead when to start stratification so you can time putting seedlings outdoors in good weather.


These pawpaw seeds require 100 days cold stratification.




Once you have noticed your seeds germinating it is time to plant them into soil.  Tweezers are quite handy for picking up the germinated seeds.  Plant into seed starting mix and place in a sunny location until they are large enough to plant outdoors in spring.

Happy growing!

FOOD FOREST MEDICINE Monograph #7: Winter Green



Common Name:  

Wintergreen

Latin Name: Gaultheria procumbens




Brief Description:

Gaultheria procumbens is an evergreen shrub growing to 0.2 m (0ft 8in) by 1 m (3ft 3in) at a medium rate.
It is hardy to zone 4. It is in flower from Jul to August, and the seeds ripen from Oct to December. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects. The plant is self-fertile.

Suitable for: light (sandy) and medium (loamy) soils and can grow in nutritionally poor soil. Suitable pH: acid and neutral soils and can grow in very acid soils.
It can grow in full shade (deep woodland) or semi-shade (light woodland). It prefers dry or moist soil and can tolerate drought.

Parts Used/Edible Uses:   

Edible Parts: Fruit; Leaves.
 
Edible Uses: Condiment; Tea.
 
Fruit - raw or cooked. It has a very strong spicy taste. Best after a frost, the fruit hangs onto the plant until spring if it is not eaten by birds etc. The fruits can also be used in pies, or made into jams etc. The fruit is up to 15mm in diameter.  A stronger tea can be made by first fermenting the bright red leaves. 'Oil of wintergreen' can be distilled from this plant. It is used to flavour beer, sweets, chewing gum etc.

Medicinal Uses:

Analgesic;  Anti-inflammatory;  Anti-rheumatic;  Aromatic;  Astringent
Carminative; Diuretic;   Stimulant;  Tonic.

Other Uses: Essential.

An essential oil is obtained from the leaves by steam distillation. In order to obtain the oil, the leaves need to be steeped for 12 - 24 hours in water. The essential oil is used as a food flavouring, medicinally (the original source of Wintergreen oil used as a liniment for aching muscles) and in perfumery and toothpastes. In large doses it can be toxic. A good ground-cover plant for shady positions though it requires weeding for the first year or so. Forming a dense tuft-like carpet, it roots as it spreads and should be spaced about 45cm apart each way.


Safety/Cautions/Interactions:  

The pure distilled essential oil is toxic in large doses. If used orally may aggravate stomach ulcers. Do not use if allergic to aspirin. Avoid if less than 12. Topical use can cause contact dermatitis.
