DANDELION

Taraxacum officinale L.

Compositae/Asteraceae

Description:  Basal whorl of toothed leaves.  Yellow, regular flowers.  Common yard bounty. 
Photo and information.  Also see Edible Flowers.

TIP: This plant is easily grown indoors in the window. Eight plants under lights or in a window will provide ample amounts of edible leaves for two people.

Food: My favorite vitamin and mineral rich salad green. Eat it daily year around. Tear it into small pieces for salad, mix with thyme and fennel, nasturtiums, along with other salad leaves (see recipes). Thyme and fennel balance the bitterness in the dandelions. Make a mineral rich tea from roots and leaves. Gently simmer chopped fresh root for mildly to very bitter tea. COOKING: fresh leaves early in season on salads, as season progresses leaves become more bitter, pour copious amount of water on plant in evening before morning harvest to sweeten leaves. Leaves even when bitter are great in stir fry, try cooking with tofu, meat eaters try oyster oil, cayenne, dandelion and beef strips.

Medicine: Commission E approved for dyspepsia, urinary tract infections, gallbladder and liver complaints, appetite loss. Dandelion is one of the most potent diuretics, performance equal to prescription pharmaceutical Furosemide in animal studies. Dandelions are stimulating, a tonic and mild laxative with blood glucose regulating capacity. The bitter taste of dandelion is an appetite stimulant and stimulates entire digestive system (cholagogue) improves appetite and may be helpful treating anorexia. Raises HCL in stomach, improving calcium breakdown and absorption. Spurs bile production. Bile is necessary for fat and cholesterol emulsification, digestion and absorption. Fiber locks up bile thereby preventing emulsification of saturated fat and cholesterol. This causes the liver to make more bile from cholesterol. Thus, dandelion and other bitter high fiber greens can theoretically lower cholesterol in three ways: 1. They stimulate secretion of bile requiring more production of bile from cholesterol. 2. Fiber in the plants locks up bile in the digestive system preventing cholesterol emulsification, thus it cannot be absorbed. 3. Fiber removes bile from body, requiring the liver to break down more cholesterol to make more bile (these factors may effect atherosclerosis, reduce stroke, and lower blood pressure, hypertension). Liver cleansing and tonic. Stimulate liver, may aid digestion, and help cleanse blood. Diuretic that may be helpful for PMS.

Mild laxative. May relieve inflammation and congestion of gall bladder and liver. May lower cholesterol and blood pressure (hypotensive).

Chemistry: Leaves high in cancer fighting antioxidants, vitamin C and Beta Carotene. Root contains inulin, gluten, potassium, taraxacin. White latex like exudate is made up of alcohols, (glycerin) caoutchouc, taraxasterols and acetic and other acids. Essential fats linoleic and linolenic in roots, leaves and seeds. Beta sitosterol in flowers as well as flavonoids, lutein, flavoxanthin...(5) (6)

Wildlife/Veterinarian: Goldfinch like the seeds, another great reason to grow this in your lawn. Dandelion root and dandelion tea is an integral constituent of my pigeon racing formula teas.

 

Dates, Date Palm

Phoenix dactylifera L.

Palmaceae

 

Food: High fiber fruit, small seeds, skin and flesh provide excellent source of soluble and insoluble fiber.  Try this date recipe:  slice dates in half, slice pieces of Italian or French bread, press and knead blue cheese until soft (room temperature).  Spread the softened cheese over the bread, place date on cheese.  Outstanding.

Medicine:  Date honey is produced in north Africa.  Date honey is used to treat problems of the chest and sub sternum area. In Ayurvedic medicine date palm  is used to treat, kidney disease, stomach (gastric complaints), headaches, external wounds and external inflammations, bronchitis, clouding of the cornea (cataracts).

(photo, more)

Food: Not used as food, toxic.

Medicine: This was big medicine for Native Americans. Whole plant contains alkaloids: atropine and scopolamine. Atropine was used traditionally in eyes to get the Belladonna effect: huge dilated pupils. Scopolamine is used in the motion sickness patch (to treat dizziness). Atropine is sedative to the parasympathetic nerves and has been used in treating Parkinson's disease.

Scopolamine patches used to treat asthma and motion sickness. Traditionally leaves were smoked by Native American to treat asthma and other respiratory conditions. Smoking of leaves may also induce hallucinations. According to Foster and Duke in their book Medicinal Plants, Peterson Field guides, p. 182 licorice (Glycyrrhiza) may be an antidote to toxic properties of the alkaloids in this plant.

Chemistry: Primary substances: alkaloids scopolamine and atropine.

Warning: Many fatalities have been reported from abuse of this plant.

Daylily

Uses:  (photo and information)

Food:  Novices use this plant only in bloom .  Early growth resembles poisonous Iris shoots, other toxic lilies and daffodils.  Eat roots judiciously.  Younger roots are better than tough older ones. I have not made them a part of my wild food diet because of the danger inherent in eating lily roots (contains cardiac glycosides).  Flowers and flower buds have onion like taste and are good in salads.  Tear the petals apart and spread throughout the salad.  Whole buds may be stir fried with meat and vegetables.  Buds may also be batter dipped and cooked tempura style.  Try chopping buds and flowers mix with seasoned pork and stuff in won tons...Steam.   Dip in Japanese flavor principle (see recipes).

Flowers and buds may be dried in a food dryer.  Then placed in the freezer for use in stir fry, etc.

Roots may be baked and boiled, then snip one end and squeeze starch out like paste.  Much the same way garlic cloves are used after roasting.  This may be risky business, see next.

Warning:  Eating young shoots and roots according to Chinese studies may caused the accumulation of toxins leading to damage of the eyes.  Should colchicine be present this chemical is toxic.

Medicine:  Root tea used in Orient as a diuretic to improve urination, treat jaundice, internal bleeding, excessively bleeding uterus.  Root extracts may be antimicrobial, antiparasitic (flukes).  In China, flowers are used as a poultice, poultice on hemorrhoids, flowers are astringent

Chemistry:  Carotenoids, vitamin C, protein essential fatty acids, bioflavonoids, perhaps colchicine.
