Yellow Dock

December 30, 2010 By Cloverleaf Farm

Botanical and Common Names

Family Polygonaceae
Rumex crispus (Yellow Dock, Curled dock, Curly-leaf Dock, Rumex, Sad Dock; Spanish: Lengua de Vaca, Yerba Colorado, Raiz Colorado; Nahuatl: Arlinan, Axixpatlicóztic)
Rumex aquaticus (Water Dock)
Rumex acetosella (Sheep’s Sorrel, Sorrel, Garden Sorrel)
Rumex alpinus (Monk’s Rhubarb)
Rumex obtusifolius (Broad-Leaved Dock)

Cautions

Yellow dock should not be taken by those with a tendency to develop kidney stones.
Excessive intake can irritate the intestinal tract.

Description

Indigenous to Europe and Africa, the dock varieties now grow wild in many regions of the world, thriving on dumps, roadsides, and in ditches. It is a perennial, growing from one to five feet with curled, lance-shaped leaves which alternate along the stem reaching lengths of up to ten inches. It has spikes of small, reddish, woody fruits. The plant turns a striking rust-red in the fall and during the winter. The dead stalks and heavy seed panicles at the top of the stem are easily recognizable. The reddish-brown root is shaped something like a carrot; and, inside, the colour is a yellowish-orange. The darker the yellow, the stronger the medicinal qualities of the root. The root is dug up in autumn, chopped, and dried.

History

In the past, the leaves were eaten as a spring tonic, but now only the root is used. It was also used as a salad vegetable and a cooked green.

The early settlers to North America quickly learned about poison ivy. One old-time cure was boiled yellow burdock mixed with vinegar and applied to the sores.

The Iroquois used tea made from the roots to treat upset stomach, kidney problems, and general bowel problems. Many tribes, including the Blackfoot, Paiute, and Shoshone, used the herb topically by applying the mashed root to sores and swellings.

Sorrel is an ingredient of a Native American anticancer remedy known as Essiac, which also includes burdock, slippery elm, and Chinese rhubarb. Western herbalists learned of it early in the 20th century when a Canadian nurse observed the recovery of a breast cancer patient who had used the formula some twenty years previously. This nurse began using it with great success; and, despite attempts to extract the formula for financial gain, she stood firm in giving it out to whomever needed it without charge. Despite the successful treatments, no proper clinical trials have ever been undertaken when it was understood that it could not be exploited.

Apparently, the shape and reddish colour of the root must have reminded someone of a cow’s tongue and thereby named it “Lengua de vaca”.

The Aztecs called it “atlinan”, meaning “its mother is water”. This referred to the plant’s preferance in growing in streambeds. They also called it “axixpatlicóztic”, meaning “yellow urine medicine,” which referred to its use as a diuretic.

In a 1629 treatise entitled Heathen Superstitions That Today Live Among the Indians Native to This New Spain, a cleric described an Aztec remedy using the herb in an enema to treat stomachache and fever. The roots and leaves were also ground and sprinkled on wounds and sores.

In Europe, the herb has been used as a purgative since the time of the ancient Greeks. Dock leaves were also used to treat scrofulous sores, sore eyes, and glandular swellings. To cure itchy skin, the leaves were bruised, mixed with butter, lard, or cream, and placed on the area.

The Mennonites used the plant as a blood purifier and treated many liver ailments with it.

Ancient Arab physicians recommended the plant for hepatitis and poor digestion.

Although considered by many to be another useless weed, it is one often targeted by herbicide producers, along with other medicinal “weeds”, including the dandelion and burdock.

Key Actions

astringent
detoxifies
diuretic
mild laxative
stimulates bile flow
tonic

Key Components

anthraquinones (up to 4% nepodin, emodin, chrysaphanol, and physcion)
tannins
oxylates
volatile oil
vitamins (A, B, and C)
minerals (especially manganese, phosphorus, calcium, iron, magnesium, and selenium)

Medicinal Parts

Aerial parts, leaves, roots
Isolated anthraquinones are irritants and have a laxative effect.
Scientific examination has found the plant to inhibit Escherichia, Salmonella, and Staphylococcus.

Traditional Uses

All members are used as a detoxifying herb; and the fresh juice has a notable diuretic effect, as well as being mildly laxative. The anthraquinones have a purgative effect on the colon; and, although not as strong as Chinese rhubarb or Cascara, it is a mild alternative. It is quite effective when used with licorice for constipation. Short term use of decoctions internally, not only relieve constipation, but are also used for boils by mixing an equal amount of yellow dock, burdock, and red clover.

It was used for such ailments as stomach and liver ailments and to purify the blood. The root is said to be an effective treatment for post-hepatitis flareups and difficulty in processing fatty foods. It stimulates the flow of bile, thereby enhancing digestion and getting rid of toxic wastes. Such cleansing is used to treat a number of conditions marked by stagnant toxins in the body including acne, boils, eczema, psoriasis, fungal infections, sluggish digestion, constipation, arthritic and rheumatic conditions. It also holds potential as a long-term treatment for chronic disease, especially that of the gastrointestinal tract.

It is commonly used for acute and chronic inflammation of the nasal passages, throat, and respiratory tract, as well as for wounds and abrasions, gum problems, and headache.

Used along with other herbs, it is an antibacterial adjuvant.

The leaves of all species, but especially the Broad-leaved Dock, are used as an antidote to nettle stings, with the leaf being rubbed over the affected area.

Various cultures around the world have used yellow dock for ailments ranging from cancer and tuberculosis to syphilis and leprosy, and ringworm and hemorrhoids.

In India, the juice from the roots are used for toothaches, while the powdered root is used for gingivitis and as a dentifrice.

The Maoris of New Zealand chew the leaf first then apply it to wounds, which, they claim, will heal without scaring.

Mixed with equal parts of sarsaparilla, dandelion root, burdock, oregon grape root, and figwort, yellow dock is effective in treating psoriasis.

Rose

December 28, 2010 By Cloverleaf Farm

Botanical and Common Names

Family Rosaceae
Rosa species
R. canina (Wild Rose, Dog Rose, Rose Hip, Brier Hip, Hip, Brier Rose, Eglantine Gall, Hogseed, Dog-berry, Sweet Brier, Witches’ Brier, Hep Tree, Hip Fruit, Hop Fruit, Hipberries)
R. arkansana (Prairie Wild Rose, Sunshine Rose, Arkansas Rose, Meadow Rose, Pasture Rose)
R. laevigata (Cherokee Rose)
R. gallica var. centifolia (Apothacary’s Rose, French Rose, Cabbage Rose, Hundred-leafed Rose)
R. damascena (Damask Rose)
R. rugosa (Rugosa Rose, Saltspray Rose, Beach Tornado)
R. multiflora (Japanese Rose)

Cautions

Use only the rose species listed here for medicinal purposes and not garden hybrids.

Because of the high price of rose oil, adulteration is common. Therefore, for medicinal purposes, use only the best high quality, genuine rose oil.

Consumers should be aware of the fact that much of the natural vitamin C in some rosehip products is lost in the manufacturing process. To compensate, some fortify the products with artificial vitamin C.

Description

Rose species are native to various places, but most are from the Middle East. They have been cultivated for thousands of years, but some can still be found in the wild although most are cultivated for commercial or private use. Typically, roses are climbing or bushy perennials with thorny stems and varying shapes and colours of flowers. All have a unique rose scent. The wild roses typically grow everywhere on the prairies of North America in ravines and stream banks, bluffs, thickets, and along roadsides and railroads.

History

In the 1st century CE, Pliny the Elder recorded thirty-two different medicinal uses of the rose.

Roses were grown in medieval gardens more for medicine and food than for beauty.

Ironically, the Cherokee rose is native to China, but now grows throughout much of North America and is the state flower of Georgia. It was used in China to treat diarrhea.

In the 19th century, it was proven that roses contain essential oils. Rose oil is distilled from the petals and used in aromatherapy.

With the discovery of vitamin C in the 1930s, and subsequent claims by Linus Pauling that massive doses of the nutrient could cure the common cold, rosehips have been of much interest because of their high content of this nutrient.

Unlike Western medicine, all indigenous cultures believe that there is no separation between the physical and the mental or spiritual being, and both must be assessed before healing occurs. The same belief has long been held true regarding the rose and is seen in this saying, “Roses are good for the skin and the soul”.

The botanical name of the Wild Rose is reflected in its use by the Romans. R. canina species was used for rabid dog bites.

Roses continued as official medicine until well into the 1930s (British Pharmacopoeia) when the tincture of the Apothocary’s Rose was prescribed for sore throats. Roses were also widely used as mild astringents and to flavour other medicines.

There were dozens of varieties of roses in North America. The Native Americans learned how to use whatever grew in their region, as a medicine and, in cases of emergency, as a food. The leaves, petals, hips, and roots were widely used for a variety of conditions, including colds, fevers, diarrhea, influenza, and stomach troubles.

The Omahas steeped the hips or roots to make a wash to treat eye inflammations.

In the Great Lakes region, the Chippewas made a tea from the wild rose and used the berries for food and for diseases of the eye. They used the inner bark of the roots to treat cataracts.

The Pawnees collected the insect galls from the lower parts of the stems, and charred and crushed them for use in dressings for burns. The insect or disease-produced galls were found in the archaeological remains of the Hill Site, near present-day Guide Rock, Nebraska, which was occupied by the Pawnees in the early 1800s.

The Flathead and Cheyenne tribes treated snow blindness with an eyewash made by boiling the petals, stem bark, or root bark. The Cheyenne also boiled the inner bark to make a tea valued for treating diarrhea and stomach trouble.

Many other tribes used all parts of the plant for various remedies. The Crows boiled the crushed roots and used them in hot compresses to reduce swellings. They also sniffed vapor to stop bleedings from the nose or mouth.

The Arapahos used the seeds to produce a drawing effect for muscular pain.

Key Actions

antispasmodic
aphrodisiac
astringent
antibacterial
antiviral
antiseptic
anti-inflammatory
blood tonic
cleansing
digestive stimulant
expectorant
increases bile production
kidney tonic

vitamins and minerals (especially A, B, E, and K, potassium and iron)

Medicinal Parts

Flowers, petals, rosehips, root, root bark, essential oil

There are some 300 chemical constituents of which only about 100 have been identified.

Depending on the source, some rose teas are able to supply as much as 1000 mg. per cup. Recent studies now indicate that taking more than 2000 mg. of vitamin C per day changes the vitamin into a pro-oxidant that actually increases cellular damage caused by unstable free radicals. Other experts seem to think that this action takes place with as little as 1000 mg. of vitamin C per day.

Remedies

The seeds of the Japanese rose are used in Oriental medicine as a diuretic and laxative.

Infusions of dried rose petals are used for headaches and taken after meals to aid digestion.

Steam inhalation of a decoction of rose petals, lavender, and hops help induce sleep.

Compresses soaked in infusions of the dried flowers make a good anti-inflammatory remedy for the eyes or any other inflamed area of the body and applied cool for headaches.

Rosehip tincture is an effective astringent for treating diarrhea or in relieving colic or as a component in cough remedies.

Rosehip syrup is used as a cough remedy or taken as a source of vitamin C.

Rosehip decoction is taken with other herbs to treat chronic diarrhea associated with stomach weaknesses.

Flower decoctions are taken with motherwort for heavy menstruation or combined with Chinese herbs for liver dysfunctions.

Tinctures from the petals are used for diarrhea or sluggish digestion. When combined with other herbs, they areused to treat irregular or heavy menstruation.

Gargles made from petal infusions, used alone or combined with sage, are used for sore throats.

Creams from the essential oil are used to treat dry or inflamed skin.

Lotions from the essential oil are combined with lady’s mantle tincture for vaginal itching.

Rosewater combined with equal amounts of witch hazel is used as a moisturizing lotion for skin prone to pimples or acne. (Rosewater is a by-product of the steam distillation of Bulgarian rose oil and is used as a skin remedy.)

A few drops of essential oil can be added to bathwater for depression, grief, or insomnia.

Massage oil is made by mixing a few drops of essential oil with a neutral oil and used to relieve stress and exhaustion or for sluggish digestion.

Traditional Uses

The dried hips of the wild rose are especially high in vitamin C, having three times that of citrus fruits, and have long been used to prevent scurvy.

The Chinese use the flowers as a qi or energy stimulant and blood tonic to relieve stagnant liver energies. They are also used for digestive irregularities or with motherwort for heavy menstruation.

The Damask rose blooms for only a couple of weeks, during which time the petals are collected and steam distilled to produce true Bulgarian rose oil used in about 96% of all women’s perfumes. Medicinally, it is an important nervine used for depression and anxiety.

The cabbage rose is used to produce French rose oil, which differs significantly in its chemical composition from Bulgarian rose oil and has a reputation as an aphrodisiac.

Feverfew

December 23, 2010 By Cloverleaf Farm

Botanical and Common Names

Family Asteraceae (formerly Compositae)
Chrysanthemum parthenium syn. Tanacetum parthenium (Feverfew, Featherfew, Featherfoil, Midsummer Daisy)
Spanish: Altamisa Mexicana, Santa Maria, Yerba de Santa Maria

Cautions

Do not take during pregnancy.
The plant is restricted in some countries because it carries a risk of toxicity and should be used only under the guidance of a knowledgeable herbalist.
Some experts warn against taking feverfew along with such blood-thinning drugs as aspirin and warfarin (Coumadin), antimigraine drugs, high doses of vitamin E, ginkgo biloba, calcium channel blockers, and ticlopidine (Ticlid).
Since feverfew has a mild anticoagulant effect, combining it with anti-clotting products may result in bleeding problems.

Description

Native to southeastern Europe, feverfew is now common throughout Europe, Australia, and North America. Tansy is found throughout the temperate zones in the northern hemisphere, growing in open areas, along roadsides, and close to water.

Both are herbaceous perennials growing to two or three feet in height and producing numerous strongly aromatic, clusters of yellow, daisylike flowers. They also have an erect stem and feathery compound leaves. Feverfew is a close relative of chamomile and is often confused with chamomile; but, unlike chamomile, whose flowers contain medicinal oils, the therapeutic ingredients of feverfew are found in the leaves. The leaves are picked as required, while the aerial parts, as a whole, are harvested in summer when the plant is in flower.

History

The name feverfew is derived from the Latin term febrifugia, which means to “drive out fevers”.

The use of feverfew as a migraine remedy is credited to the wife of a Welsh doctor. It is said that she ended her 50-year history of such headaches with a course of feverfew.

It has been used since Roman times to induce menstruation and given during difficult birth to aid in the expulsion of the placenta.

Dioscorides, an ancient Greek physician, gave it to women during childbirth to increase uterine contractions and to speed the birth process.

Culpeper stated, in 1653, that the main use for the herb was for women’s complaints.

For centuries, it was used to lower fevers, treat infant colic, depression, vertigo, kidney stones, and constipation. It is also used as an insect repellent and to treat minor skin wounds and to relieve the pain of arthritis.

Although not mentioned in surviving classical texts, tansy was described by medieval herbalists, notably Hildegard of Bingen in the 12th century and onward. It has since been the most common worm-expelling plant used.

Gerard also wrote that feverfew was an effective headache remedy.

Cotton Mather, an American clergyman and writer of the 1700s, recommended chewing feverfew to ease a toothache.

Key Actions

analgesic
antirheumatic
bitter
promotes menstral flow
reduces fever

Key Components

volatile oil (alpha-pinene)
sesquiterpene lactones (parthenolide)
sesquiterpenes (camphor)
vitamins and minerals (especially niacin and thiamin, chromium, magnesium, manganese, phosphorus, potassium, and selenium)

Medicinal Parts

Aerial parts

A detailed scientific investigation in Britain, in the 1980s, demonstrated its effectiveness for migraine headaches, reducing the number and severity of these attacks, as well as the degree of vomiting that often accompanies the condition. They found that parthenolide works against migraine headaches by reducing blood platelet activity and the release of histamines and prostaglandins, body chemicals that are instrumental in the inflammation and sudden widening of the blood vessels in the head. It also helps prevent the fluctuations in levels of serotonin, another chemical that is instrumental in migraine symptoms. These substances and effects may also explain the herb’s ability to reduce menstrual cramps and to relieve arthritic pain and inflammation.

Feverfew seems to be more effective as a preventative rather than relieving full-blown symptoms of migraine headaches. While the vomiting and other symptoms were milder, there was no change in the duration of the headaches according to one study. It should be noted that the quality of many commercial feverfew products is very uneven. Some lab analysis found little or none of the active ingredient, parthenolide.

Traditional Uses

As a preventative for migraines and as an alternative to taking pills that may have little or none of the active ingredients, it is recommended that chewing two or three of the dried leaves per day would be a better choice, although regular use can cause mouth ulcers. At such times, it would be best to switch to a tea.

Feverfew can be a mild sedative and euphoric and is occasionally added to compounds for the relief of nervous tension. In large doses, it can sedate those suffering from nervous hysteria, but may produce some side effects. However, moderate doses are completely safe.

Strong teas made from the leaves are used to treat skin inflammations and minor wounds.

Comfrey

December 23, 2010 By Cloverleaf Farm

Bee pollinating a Comfrey leaf flower

Botanical Name

Family Boraginaceae
Symphytum officinale

Common Names

Ass Ear, Black Root, Blackwort, Boneset, Bruisewort, Consound, Gum Plant, Healing Herb, Knitback, Knitbone, Salsify, Slippery Root, Wallwort
Spanish: Sueldo, Consueldo, Cardo Santo

Cautions

Do not use comfrey on dirty wounds as rapid healing can trap the dirt or pus.

The use of comfrey root is not suggested as it contains toxic alkaloids, mainly pyrrolizidine.

It is unclear as to whether the alkaloids are toxic in the context of the whole plant, since they are only present in minute amounts and are often completely absent from samples of dried aerial parts. The highest concentration is in the root, having almost twice as much as in the aerial parts. Until such time as it is proven one way or the other, use of the root internally is not advised. It should be noted that Swedish researchers have determined that these alkaloids are destroyed when making a decoction of the aerial parts.

Internal use of comfrey is not recommended.

Description

Indigenous to Europe, comfrey now grows in all temperate regions of the world, including western Asia, North America, and Australia. The herb is a perennial that grows up to three feet, producing thick leaves and bell-like white to pink or mauve flowers. It thrives in moist, marshy places; but it can send down a ten-foot, or longer, taproot to raise moisture and valuable minerals. The leaves and flowering tops are harvested during the summer. The root is harvested in the spring or fall when the allantoin levels are the highest.

History

Long used to heal wounds, the comfrey leaves and roots have been used to cure ailments ranging from stubborn leg ulcers to broken bones, and hence its common name of “boneset” or “knitbone”.

During ancient times, comfrey baths were popular before marriage to repair the hymen and thus restoring virginity.

Since 400 BCE, early Greek physicians have used comfrey to stop bleeding, treat bronchial problems, heal wounds, and mend broken bones.

During the Irish potato famine of the 1840s, an Englishman named Henry Doubleday became convinced that the world could be saved from hunger and suffering by using comfrey. He established a charitable organization to research the cultivation and use of the plant that exists to this day and continues to publish pamphlets and books on its usage.

Key Actions

astringent
anti-inflammatory
cell proliferator
demulcent
heals wounds, bone, and cartilage

Key Components

allantoin (up to 4.7% mainly in flowering tops)
inulin
mucilage (about 29% mainly fructans)
nutrients (calcium, potassium, phosphorus, vitamins A, B12, C, proteins)
phenolic acids (rosmarinic)
steroidal saponins
toxic alkaloids (including pyrrolizidines)
tannins

Medicinal Parts

Aerial parts, root

The active ingredients in comfrey herb are allantoin (a substance that fosters the growth of new cells), rosemarinic acid (an anti-inflammatory), and mucilage (a gummy substance that soothes inflammed tissues).

Allantoin is credited with encouraging bone, cartilage, and muscle cells to grow. However, a soothing solution can be made from the leaves steeped in hot water; but its effectiveness is lessened by heat. The roots contain about twice as much allantoin as the leaves. Pharmacists may add allantoin to ointments and creams to enhance skin-healing properties.

Remedies

Poultices made from the fresh leaves are applied to rough skin, aching joints, sores, burns, cuts, sprains, and to reduce the swelling around fractures. They can also applied to minor fractures that would not normally be set in plaster, for example, broken toes, ribs, or hairline cracks in larger bones.

Poultices from the root are ground into a powder; a little water is added to make a paste that can be used on stubborn wounds and bleeding hemorrhoids.

Creams are used for bone and muscle damage, including osteoarthritis.

Infused oil (hot method) is used on arthritic joints, bruises, sprains, other traumatic injuries, and for inflamed bunions.

Tinctures of the comfrey root are applied undiluted to acne.

Ointments made from the leaves are used on bruises and scrapes.

Traditional Uses

Comfrey leaves are dried, ground up, and mixed with water, a moisturizing oil, or aloe vera to form salves or pastes that can be used externally to promote the healing of skin ailments, while reducing inflammations and infection. When the crushed herb is applied to an injured limb, the allantoin is absorbed through the skin to speed healing. When a compress is applied immediately to a sprained ankle, it can significantly reduce the severity of the injury.

A lotion or solution of comfrey leaves made by soaking them in hot, but not boiling, water andcan be applied to abrasions to soothe the irritation.

Dried roots may be ground up and dissolved in hot water to form a mucilage that can bind together such open skin ulcers as bedsores, that have resisted other forms of healing. Although the root has similar properties as the leaves, it tends to be colder in nature and more nourishing in action, therefore, better suited in treating varicose ulcers.

The combination of tannins and mucilage helps soothe bruises and scrapes.

Externally, comfrey leaves are useful in healing stubborn skin ulcers, bedsores, and other lesions. They can also promote the healing of minor burns, eczema, and psoriasis, soothe bee stings and spider bites (including those of the brown recluse), and treat skin staph infections and athlete’s foot. A poultice can be made from freshly chopped leaves and applied directly to the wound and covered lightly with a bandage. This should be changed every day, and the wound cleansed with water (not tap) and a mild soap. The area can first be cleansed with hydrogen peroxide if there is infection present.
