The History of Herbal Medicine
There is a description of history and application
of twenty-five herbal remedies:
Aloe Vera(Aloe vera): Aloe is
a widely used ingredient in cosmetics (hand lotions, shaving creams,
etc.), but first of all it is a medicinal herb. Aloe gel is used
externally on the skin essentially for its emollient (skin softening)
property.
Another use for aloe comes from the latex of the
leaf. The FDA (Food and Drug Administration) and a
number of European countries have recognized aloe latex as a safe and effective laxative
ingredient. For example, in Germany, aloe latex is
employed as a stimulant laxative. Normal precautions regarding
stimulant laxatives apply to aloe. Like other stimulant laxatives,
anthraquinone-containing (a plant-based, organic compound)
purgatives like aloe need to be used for the short-term only and not
during pregnancy or lactation. Abuse may
cause an electrolyte
imbalance, resulting in depletion of potassium salts and thus may
adversely affect heart function. One should remember that these warnings are for aloe latex used as a
laxative, not the aloe gel or juice commonly consumed
by health enthusiasts for "inner cleansing."
Cayenne(Capsicum annuum): Cayenne
or red pepper is used of the systemic stimulants. It
stimulates blood flow, strengthening the heartbeat and metabolic
rate.
A general tonic, it is helpful specifically for the circulatory and
digestive systems. It may be used in flatulent dyspepsia
(imperfect or painful digestion) and colic. Cayenne may be used when
there is insufficient peripheral circulation, leading to cold
hands and feet and possibly chilblains (a form of cold injury
characterized by redness and blistering). It is
also useful for debility and for warding off colds. It is widely
used in problems like lumbago (a dull, aching pain
in the lumbar region of the back) and rheumatic pains.
Chamomile(Matricaria recutita): Chamomile flower is
used in many cultures for its pleasant-tasting tea, consumed as an
after-dinner drink to help digestion. In Europe, chamomile is
noted as a digestive aid, as a mild anodyne, and for its
anti-inflammatory
property, especially in over-the-counter preparations for oral
hygiene and skin creams.
In Germany, chamomile is licensed as an over-the-counter drug for
internal use against gastrointestinal spasms and inflammatory
diseases of the gastrointestinal tract. The extract is widely
applied for skin and mucous membrane inflammations, for bacterial
skin diseases of the mouth and gums, for
inflammation
of the mucous membranes of the throat and airways, and as an
external bath and rinse for inflamed conditions of anal and genital
regions.
Chasteberry(Vitex agnus-castus): Chasteberry is
becoming widely used as an herb that addresses various hormonal
imbalances in women. The clinical results are thought to be due to
some regulatory effect upon the pituitary gland. Researches have
shown that chasteberry helps reinstate a normal
estrogen-to-progesterone balance.
It is indicated for irregular or painful menstruation,
premenstrual syndrome,
and other disorders related to hormone function. It is especially
beneficial during menopausal changes, relieving symptoms such as hot
flashes. It may be used to aid the body in regaining a natural
balance after the use of birth control pills. Chasteberry also helps
in treating such sicknesses as fibroid cysts that occur in
smooth muscle tissue or body cavities. It may also be of value in
treating endometriosis. Several studies indicate chasteberry can
help control acne in teenagers, both among young women and men.
Echinacea(Echinacea angustifolia): Often called purple
coneflower, the term echinacea refers to several species of plants
that are generally found in the Great Plains region of North America.
The Native Americans
of this area widely used medicinal plants. They often utilized echinacea for its
external wound-healing and anti-inflammatory properties. Dr. Gerhard Madaus,
german researcher, imported
echinacea seeds to Europe and initiated the first modern scientific
research on the immunostimulating properties of this plant. Thanks to
his work, echinacea has become one of the most important
over-the-counter remedies in Germany, where it is employed for
relieving the common cold and flus.
Over 180 products are marketed in Germany,
including extracts and fresh-squeezed juices from both the roots and
leaves of echinacea.
The German government has approved oral dosage of echinacea for use
in recurrent infections of the respiratory and urinary tracts,
progressive systemic disorders such as tuberculosis, leukosis
(abnormal growth of white blood cells), connective tissue disease,
multiple sclerosis, and for surface wounds
with a poor tendency to cure. Liquid echinacea preparations have
immune-stimulating activity when administered
both orally and parenterally (denoting any medication route other
than the intestine, e.g., intravenously):
they increase the number of leukocytes
(white blood cells) and splenocytes (white blood cells of the spleen)
and enhance the activity of granulocytes (granular white blood cells)
and phagocytes (cells that have the ability to ingest and destroy
substances, such as bacteria, protozoa, and cell debris).
Ephedra or Ma-huang(Ephedra sineca):
Ephedra is a medicinal plant that has been cultivated for over five
thousand years in China, where it was used for asthma and hay
fever-like conditions. Also known as ma-huang, the stems contain two
primary alkaloids, ephedrine and pseudoephedrine, which are now
approved for use in over-the-counter decongestant and bronchial
drugs. Ephedrine has a marked peripheral vasoconstricting (causing
constriction of the blood vessels) action. Pseudoephedrine is a
bronchodilator (able to dilate the windpipe), approved for use in
asthma and certain allergy medicines. Ma-huang and its extracts are
found in a number of herbal formulas that are designed to increase
energy and reduce appetite. Both ephedrine and pseudoephedrine have
central nervous system (CNS)-stimulating properties, ephedrine being
more active. The CNS activity of these alkaloids has been
characterized as being stronger than caffeine and weaker than
methamphetamine (a central nervous system stimulant). Therefore this herb should be used with caution or
avoided by those with high blood pressure, diabetes, glaucoma, and
related conditions where hypertensives are contraindicated.
Feverfew(Tanacetum parthenium): Feverfew is an herbal
medicine known since Greco-Roman times. It was applied as a remedy for difficulties associated with young women's
menstrual cycles (the word parthenium is derived from the Greek word
parthenos, meaning "virgin") and was later used in
European herbalism to reduce fevers (the common name feverfew being
a corruption of the Latin word
febrifuga, an agent that
lowers fevers). In the past ten years interest in this herb has
essentially increased, because of several clinical studies that have been published in
British medical journals. Research shows that feverfew leaves not
only bring relief in a significant number of migraine patients who
have not responded positively to conventional medications, but also
helps to prevent the onset of adjunctive episodes.
Recently, the Canadian government's Health Protection Branch (equivalent
to the United States' FDA) has approved feverfew leaf extract for
migraine prevention, as long as the products contain a minimum of
0.2 percent parthenolide, a substance in the feverfew leaf that has
been identified as being the primary active component.
Early herbal literature also attributes anti-rheumatic properties to
feverfew, but this has not been confirmed by twentieth century
research.
Garlic(Allium sativum): Garlic is also medicinal herb,
used by traditional medicines
all over the world and its applications are as varied as its
geographical distribution. The chemistry and pharmacology of garlic
is well studied; over one thousand research papers have been
published in the past twenty to twenty-five years. Garlic and its
preparations are known for their antibiotic, antifungal, and
antiviral
activity; for use in helping clear congested lungs; for coughs and
bronchitis; as a preventive measure for the common cold and flus;
and for intestinal worms, dysentery, sinus congestion, certain
ulcers, gout, and rheumatism.
Garlic even has chemopreventive properties-helping to prevent
certain cancers. Recent reports by the National Cancer Institute on
a large population of subjects in China indicate that the
consumption of garlic and other members of the
allium genus (onions,
leeks, shallots) can help lower the incidence of stomach cancer.
Western countries have shown interest in the
herb's ability to provide important cardiovascular
benefits, including slightly lowering blood pressure, aiding in the
thinning of the blood, and reducing platelet
aggregation (the clustering of disks found in human
blood that facilitates blood coagulation). The chemical basis of
garlic's anti-thrombotic effect (the ability to prevent harmful blood
clotting) has been studied.
It has shown an ability to aid certain immune functions,
particularly increasing natural killer cells' activity.
Studies indicate that be it raw garlic, dried garlic, garlic oil, or a
prepared commercial produc it is always beneficial. However, odorless or odor-controlled garlic preparations have a high
degree of activity and are appropriate for those who do not wish to
suffer the problems associated with garlic's characteristic odor,
such as bad breath. In Germany, garlic extracts are approved
over-the-counter drugs to supplement dietary measures in patients
with elevated blood lipid (liquid fat)
levels and to prevent age-associated vascular changes.
A scientific panel of the European community has also endorsed
garlic for its cardiovascular benefits.
Ginger(Zingiber officinalis): Ginger is widely used as a
medicinal herb in Chinese and Ayurvedic medicine, often added to
herbal formulas to increase digestion and the activity of other
herbs. In the past ten years, ginger has become best known for its
anti-nausea and anti-motion sickness activity. A number of clinical
studies have confirmed ginger's ability to act on the
gastrointestinal
system and allay nausea.
Unlike the leading over-the-counter drug, Dramamine, ginger does not
relieve nausea by suppressing central nervous system activity.
Rather, the effect is explained by the antiemetic (preventing or
relieving nausea and vomiting) effects of this herb, which are well
documented,
though more research is needed. Ginger is also has
cardiotonic properties.
The herb has been used in traditional medicine for migraine relief,
and fresh ginger juice has been applied topically in Traditional
Chinese Medicine as a burn remedy.
Ginkgo(Ginkgo biloba): Ginkgos are the oldest living trees on earth. They
first appeared about 200 million years ago and, except for a small
population in northern China, were almost completely destroyed in
the last Ice Age. Ginkgo leaves contain several compounds called
ginkgolides that have unique chemical structures. The leaves were
mentioned in a major Chinese herbal text of the Ming dynasty in 1436
and another in 1505. A standardized extract was developed in the
past twenty years in Germany to treat a number of conditions
associated with peripheral circulation.
It is currently licensed in Germany for the treatment of cerebral
dysfunction, with the following symptoms: difficulty in memory,
dizziness, tinnitus, headaches, and emotional instability coupled
with anxiety. It is also patented as a supportive treatment for
hearing loss due to cervical syndrome and for peripheral arterial
circulatory disturbances, such as intermittent claudication (a
severe pain in the calf muscles resulting from inadequate blood
supply).
Ginkgo leaf extracts are also used for heart and eye diseases, and
accidents involving brain trauma. At least three volumes of
technical papers on the chemistry, pharmacology, and clinical
studies on
Ginkgo biloba extract have been published.
Ginseng(Panax ginseng, eastern ginseng;
Panax
quinquefolius, American ginseng): Ginseng has an ancient history
and has gathered much folklore about its actions and uses.
The genus name
Panax is derived from the Latin word
panacea
meaning "cure all." Many of the claims that surround
ginseng are overstated but it is clearly an important remedy,
receiving attention by researchers around the world.
It is a powerful adaptogen,
aiding the body to cope with stress, primarily through effects upon
the functioning of the adrenal gland.
Ginseng has antioxidant,
antihepatotoxic (liver-protecting),
and hypoglycemic
effects. Thus there is a wide range of possible therapeutic uses.
The main application is with weak, debilitated, stressed, or elderly
people, where these properties can be especially useful. Moreover, ginseng may lower blood
cholesterol
and stimulate a range of immune system
and endocrine responses. But one should remember that abuse can
cause serious side effects, such as headaches, skin problems, and other reactions. For this
reason, the proper dosage for the individual should be determined
and respected.
Goldenseal(Hydrastis canadensis): American herb
goldenseal is used as a tonic
remedy that stimulates the immune response. It is also directly antimicrobial
itself. It can help in
many digestive problems, from peptic ulcers to colitis.
Its bitter stimulation helps in loss of appetite, and the alkaloids
it contains stimulate production and secretion of digestive juices.
The antimicrobial properties are due to alkaloids, such as
berberine.
Berberine, found in a number of other herbs as well, has marked
antimicrobial activity. Not as powerful as an antibiotic, it
nonetheless has a broad spectrum of activity. Effects have been
demonstrated against bacteria, protozoa, and fungi, including Staphylococcus
sp., Streptococcus sp., Candida
albicans, and Gardia lanbia.
Berberine's action in inhibiting candida prevents the overgrowth of yeast
that is a common side effect of antibiotic use. This alkaloid activates macrophages (cells that digest cell
debris and other waste matter in the blood) in a number of ways.
Traditionally, goldenseal has been used during labor to help
contractions, and for this reason it should be avoided during
pregnancy. Iit can also be helpful in eczema, ringworm,
itching, earache, and conjunctivitis.
Hawthorn(Crataegus oxyacantha): Hawthorn has been used
in folk medicine in Europe and China for centuries. Europeans have
utilized both the edible fruit as well as the leaves and flowers,
primarily for their beneficial effects on the cardiovascular system.
Hawthorn is one of the primary heart tonics in traditional medicine.
Fruit and leaf extracts are known for their cardiotonic, anodyne,
and hypotensive
activities. In Germany, hawthorn extracts are used clinically for a
number of heart-related conditions, often in conjunction with
digoxin, the basic conventional pharmaceutical drug. Hawthorn has
been extensively tested on animals and humans and is known to cause
the following actions: decreases blood pressure with exertion;
increases contractility (ability to contract or shorten) of the
heart muscle; increases blood flow to the coronary muscle; decreases
heart rate; and decreases oxygen use of myocardium (the middle layer
of the walls of the heart).
In Germany, hawthorn extracts are approved by the German Ministry of
Health for declining heart performance, sensations of pressure or
restrictions in the heart area, senile heart in cases where
digitalis is not yet required, and mild forms of bradyarrhythmia (slow
heart beat).
Hops(Humulus lupulus): Hops has been used as a
bittering and preservative agent in brewing for centuries. In
Germany, due to its calming and sleep-inducing
properties, hops was patented for use in states of unrest and anxiety as
well as sleep disorders. European medicinal plant researchers have approved the
use of hops for such conditions as nervous tension, excitability,
restlessness, and sleep disturbances, and as an aid to stimulate
appetite. Unlike other types of anodynes, there are neither
dependence nor withdrawal symptoms reported with the use of hops,
nor are there any reports of negative side effects.
Licorice(Glycyrrhiza glabra): Licorice has an
ancient history as a traditional herb medicine. It can effect an endocrine system and liver and
other organs, as medical reaserch had shown. Constituents of this herb, called triterpenes, are
metabolized in the body into molecules that have a similar structure
to the adrenal cortex hormones, which is possibly the basis for
licorice's anti-inflammatory action.
Glycyrrhizin, a triterpene, prevents liver cell injury caused by
many chemicals and is used in the treatment of
chronic
hepatitis and cirrhosis, especially in Japan.
Glycyrrhizin pres the growth of several DNA (deoxyribonucleic
acid) and RNA (ribonucleic acid) viruses, inactivating herpes
simplex virus particles irreversibly.
Licorice is used as a treatment for peptic ulceration and gastritis,
and can be used in the relief of abdominal colic. It is also used
for bronchial problems such as bronchitis and coughs. There is a
small possibility of affecting electrolyte balance with extended use
of large doses of licorice. It can cause retention of sodium, thus
raising blood pressure. The whole herb has constituents that counter
this but it is best to avoid licorice in cases of hypertension or
kidney disease, or during pregnancy.
Milk Thistle(Silybum marianum): In Europethis herb
has been used as a liver tonic. Modern phytotherapy
indicates its use in a whole range of liver and gall bladder
conditions, including hepatitis and cirrhosis. Laboratory and clinical research
of this herb reveal exciting
data about reversal of toxic liver damage as well as protection from
potential hepatotoxic
agents.
These clinical findings highlight a role for milk thistle in the
treatment of toxic/metabolic liver disease (including both alcohol-
and drug-induced forms), some forms of hepatitis, cirrhosis of the
liver, and fatty degeneration of the liver.
The best results are found in toxic metabolic hepatitis and
cirrhosis. Milk thistle shortens the course of viral hepatitis,
minimizes post-hepatitis complications, and protects the liver
against problems resulting from liver surgery. It is an excellent
remedy for use in the prevention and treatment of many liver
disorders.
Nettle (Urtica dioica): In the Western
world nettle is
one of the most widely used herbs. This common plant has received little attention from the medical
community. Throughout Europe nettle is used as a spring tonic and
detoxifying remedy. If used regularly over the long-term it can be
remarkably successful in cases of rheumatism and arthritis. It might be
surmised that nettle is
a safe immunomodulating tonic. A lectin (plant protein)
found in a nettle's leaf stimulates the proliferation of human
lymphocytes.
Traditional use of nettle in the treatment of allergic rhinitis (hayfever)
is gaining research support.
It is especially indicated for cases of childhood eczema and
beneficial in all the varieties of this condition. Fresh nettle has
been used as a safe diuretic.
Passion Flower(Passiflora incarnata):
Passion flower is used as remedy with mildly anodyne properties. In Germany, passion flower is approved as an
over-the-counter drug for states of "nervous unrest."
In Europe, passion flower is often added to other calming herbs,
usually valerian and hawthorn. Passion flower and hawthorn are often
used together as antispasmodics for digestive spasms in cases of
gastritis and colitis. Pharmacological studies indicate
antispasmodic, sedative, anxiolytic (anxiety-allaying), and
hypotensive activity of passion flower extracts.
Peppermint(Mentha piperita): Peppermint has been a
popular folk remedy for digestive disorders for over two hundred
years. Today it is one of the most economically significant
aromatic food/medicine crops produced in the United States.
In some countries in Europe, peppermint leaf is
recognized as a digestive aid due to the carminative
(gas-preventing) and cholagogue (bile
increasing) action of the aromatic oil. In Germany, peppermint oil
is approved as an over-the-counter drug for upper gastrointestinal
cramps and spastic conditions of bile ducts, catarrh (inflammation
of mucous membranes) of upper respiratory area, and inflammation of
oral mucosa.
It is also approved (in enteric, coated capsules) for irritable
bowel syndrome, as the oil exerts a relaxing effect on the smooth
muscles of the bowel. As many essential oils, peppermint oil also has antibacterial
properties. Peppermint oil and menthol
are common ingredients in over-the-counter external analgesic
products like balms and liniments. In Germany, this combination is
approved for external use for muscle and nerve pain. Moreover, peppermint oil is approved by
ESCOP (the European Scientific Cooperative in Phytotherapy) for
gallbladder inflammation and gallstones, and skin conditions such as
pruritis (severe itching) and urticaria (eruption of wheals with
intense itching).
St. John's Wort(Hypericum perforatum):
A remedy long used as an anti-inflammatory, wound-healing nervine,
St.
John's Wort has recently regained medical attention because of its mild
anodyne and pain-reducing properties, Taken
internally, it has traditionally been used to treat neuralgia,
anxiety, tension, and similar problems. It can also ease fibrositis, sciatica, and rheumatic pain.
It is even used in the case of
menopausal changes triggering irritability and anxiety. It is recommended in the treatment of depression.
Recent research has suggested a role for this herb in the treatment
of virus infections, from influenza to HIV,
and thus it is currently the focus of intense investigation. Used
externally, it is a valuable curing and anti-inflammatory remedy.
As a lotion it will speed the curing of wounds and bruises,
varicose veins, and mild burns. The oil is especially useful for
healing sunburn.
Saw Palmetto (Serenoa repens): Saw
palmetto is a herb that acts to tone and strengthen the male
reproductive system. It may be used with safety where a boost to the
male sex hormones is required. It is most effective in cases of
benign prostatic hypertrophy (enlargement of the prostate
gland).
The treatment of this condition with plant-based medicines is
attracting the attention of the medical community.
It can help in cases of prostatitis (inflamed prostate gland) if
combined with echinacea and bearberry.
Senna(Cassia angustifolia): Senna is a laxative from
the leaves and pods of the senna plant, a member of the pea family
that is derived from ancient Arabic medicine. In Europe and in the
United States, extracts from senna are approved in over-the-counter
stimulant laxative products. The German government has approved
senna for all conditions in which constipation and the need for soft
stools is indicated. There are no known negative side effects
connected with the use of senna, other than those normally
associated with the use of stimulant laxatives, in which case,
long-term use or misuse can result in dependency and electrolyte
loss.
Like other stimulant laxatives, senna should not be used during
pregnancy or lactation unless professionally supervised.
Siberian Ginseng or Eleuthero(Eleutherococcus
senticosus): Siberian ginseng is one of the best adaptogen
herbs, increasing the body's ability to resist and endure stress.
This herb has a very low toxicity. Clinical and
laboratory researches has been conducted on Siberian ginseng in the
former Soviet Union. Initial findings from controlled experiments
indicate a dramatic reduction of total disease occurrence,
especially in diseases related to environmental stress. This herb
can help in treatment of such illnesses as chronic gastritis, diabetes, and atherosclerosis
(hardening of the arteries). Results from surgical studies show that
Siberian ginseng speeds postoperative recovery and is being used in
this way in the treatment of cancer patients, easing the stress
response that can aggravate metastasis
(the spreading of a tumor
from its site of origin to distant sites).
Siberian ginseng reduces the cytotoxicity (cell-attacking nature) of
antineoplastic (cancer-fighting) drugs, and the narcotic effects of
anodynes.
Valerian(Valeriana officinalis): The odorous root of
valerian has been used in European traditional medicine as a
stimulant for centuries. In Germany, valerian root and its teas and
extracts are approved as over-the-counter medicines for "states
of excitation" and "difficulty in falling asleep owing to
nervousness."
A scientific team representing the European community has reviewed
the scientific research on valerian and concluded that it is a safe
nighttime sleep aid. These scientists also found that there are no
major negative reactions associated with the use of valerian and,
unlike barbiturates and other conventional drugs used for insomnia,
valerian does not have a synergy with alcohol. Founder of the American School of Herbalism,
Christopher Hobbs,
notes that other uses include nervous heart conditions, children's
anorexia caused by excitement, trembling, and stomach complaints. He
recommends a valerian-hops preparation as a good daytime anodyne as
it will not interfere with or slow one's reflexive responses.
Witch Hazel(Hamamelis virginiana):
Witch hazel is found in most households in the form of a distilled
liquid. It is a safe astringent
for common usage. As with all astringents, this herb may be used
wherever there has been bleeding, both internally or externally. It
is especially useful in the easing of hemorrhoids.
Topically it has a well-deserved reputation in the treatment of
bruises and inflamed swellings, and also with varicose veins.
Witch hazel will stop diarrhea and aid in the treatment of dysentery.
