Witch Hazel Hamamelis Virginiana Article and Photos
by Steven Foster
An antique bottle
sat in my grandmother's bathroom labeled "witch hazel." It
always piqued my curiosity. Was this some sort of
strange brew, a grandmother's secret potion? I
asked her about it. She said it was simply a
toiletry. I knew nothing more. Then one day on a
cool New England autumn day, the trees already bare
of leaves, I walked in the woods behind my
grandmother's house. There on a woodside hill next
to the old pond sat a small, fork-branched shrub
decorated in tight clusters of spider-like yellow
flowers. "What's this?" I wondered. Clutching a
branch, I took it to my grandmother. "Witch hazel," she said.
I was surprised. A plant not a potion! I had always thought
of witch hazel as a clear liquid cosmetic stocked in grandma's
medicine cabinet. Now I had a new association for a name I
had always known.
Witch hazel's
name upholds mysterious connotations. In colonial America,
the shrub's flexible forked branches were a favorite "witching stick" of dowsers used for searching out
hidden waters or precious metals. This has nothing
to do with witches, but rather originates from the
old English word for pliable branches "wych." In
England dowsers call an elm (Ulmus glabra)
the "witch hazel tree." When early British settlers
arrived in the Americas, they fancied our witch
hazel as the logical replacement for dowsing
chores, given its pliable, crooked branches.
Although it's not a hazel
(Corylus species) the source of hazel nuts,
the leaves have a striking resemblance to those of
the common American hazelnut Corylus
americana. This brings me to an embarrassing
moment early in my career. I was invited to give a
lecture at a medical school on medicinal plants.
Several years earlier, I had photographed the
leaves of "witch hazel" and showed the slide while
discussing the herb. A botanist friend came up to
me after the lecture, and quietly let me know that
I had shown a photo of American hazelnut leaves -
not the leaves of witch hazel. Since then I have
never accepted a plant's identity at face value.
Plant identification keys are a constant companion
in my camera bag.
Botany and History
Botanists deem the common witch hazel Hamamelis virginiana. The generic name, Hamamelis, comes from a name that
Hippocrates applied to the medlar (a small
hawthorn-like fruit). The name combines two Greek
word roots meaning fruit (apple) and "together," referring
to the plant's habit of producing flowers at the same time
the previous year's fruits mature and disperse seed. The fruits
are worth a mention. Witch hazel produces a capsule-like fruit
enshrining two shiny hard black seeds with white,
oily, edible interiors. These nutty seeds were
savored by Indians of the South. The flavor is like
that of pistachio nuts. Witch hazel has a
mechanical seed dispersal action. When mature, the
seed capsules explode apart with a cracking pop,
catapulting the seeds up to ten yards from the
shrub. Remember this if you bring a bouquet of
witch hazel twigs indoors when flowering in autumn.
The seed capsules of the previous year are there at
the same time. When they heat-up in the warm
confines of a home, they will explode!
In a range extending from
Nova Scotia, west to Ontario, and south to Texas,
and Florida, common witch hazel flourishes on
shaded north-facing slopes, along fence rows,
country roads, and the stony banks of brooks.
Another North American species, vernal witch hazel
(Hamamelis vernalis), found only in its
native haunts along creek beds in the Ozark
plateau, blooms in early winter, hence the name "vernal". On
winter hikes in the Ozarks, I delight to the treat of a lovely
floral fragrance in the dead of winter. Nearby, a vernal witch
hazel is covered in its delicate, often red-tinted
blossoms. Some vernal witch hazel flowers are dark red, a rare but natural form H. vernalis f. carnea.
Any shrub that blooms in
winter, even when temperatures are in the single
digits, will certainly attract the attention of
horticulturists. Ironically most witch hazel in
American horticulture come from east Asia. Two
species of witch hazel, are commonly grown in
American horticulture. One is Hamamelis
japonica, obviously from Japan. Another is Hamamelis mollis, a Chinese species. They
have also been hybridized to produce an unusual
winter or early-spring blooming ornamental deemed Hamamelis x intermedia.
Witch hazel was widely used by American Indians
as a medicinal plant. The bark was used by the
Osage to treat ulcers of the skin, sores, and
tumors. The Potawatomi placed the twigs on the hot
rocks in a sweat lodge to bathe and soothe sore
muscles with the steam. The Menomini boiled the
twigs in water, then rubbed the decoction on their
legs to keep them limber, or to treat a lame back.
Among the Iroquois, witch hazel had many uses
including a strong tea for dysentery, to treat
colds and cough, as an astringent and blood
purifier among others. The Mohegans used a
decoction of the leaves and twigs to treat cuts,
bruises, and insect bites.
The earliest works on American medicinal plants
included witch hazel, primarily noting its use to
treat eye inflammations, hemorrhoids, bites, stings
and skin sores, diarrhea and dysentery, and many
other conditions for which a plant high in tannins
would produce relief by virtue of its astringency.
Herbalists consider it one of the best plant
medicines to check bleeding, both internally and
externally. A tea made from the bark or leaves is
given to stop internal bleeding. The same tea was
injected into the rectum to allay the pain and
itching of hemorrhoids, which today comes to the
consumer in the form of "pads" or ointments for
hemorrhoid treatment. A poultice of the fresh
leaves or bark was considered useful for relieving
the pain and swelling of inflammations. Dipped in a
cotton ball, witch hazel water is dabbed on insect
bites to calm pain and relieve itching. I find it
especially soothing on chigger and tick bites, as
well as mosquito bites, and poison ivy rash.
What attracted
the attention of witch hazel as an herbal product was a
patent medicine developed in the mid 1800s. In the
1840's, Theron T. Pond of Utica, New York
established an association with the Oneida Indians
of the state. He learned from a medicine man that
they held a shrub in high esteem for all types of
burns, boils, and wounds. It was witch hazel. Pond
learned as much as he could of the extract, and
finally after several years, in 1848, Mr. Pond and
the Medicine Man decided to market the extract,
under the trade name "Golden Treasure". After
several moves and sales of the company, a
manufacturing facility was established in
Connecticut, and after the death of Theron Pond,
the name of the witch hazel preparation was changed
to "Pond's Extract".
Witch Hazel Today
The witch hazel industry is still centered in
Connecticut with the E. E. Dickinson Co., the T. N.
Dickinson Co., and the American Distilling and
Manufacturing Co., producing most of the witch
hazel extract sold on the American market. Much of
the harvest still comes from the woods of
northwestern Connecticut, where landowners contract
directly with the manufaturers. Harvest begins in the
autumn. Branches are cut to the ground, but
resprout, producing a new harvest in a few years.
Portable chippers allow for on site processing. It
is then taken to the factories for distillation in
stainless-steel vats. The witch hazel is steam
distilled for thirty-six hours, then re-heated,
condensed and filtered. Alcohol is added as a
preservative.
Witch hazel "extract" is
a steam distillate of the recently harvested twigs of
the shrub, with about 14 percent alcohol added.
This is the witch hazel "water" that reaches most
pharmacies in America. In Europe, however, a
water-alcohol extract of witch hazel twigs and
leaves is more commonly used. Witch hazel is also
used an astringent ingredient in a wide range of
personal care products including deodorants, after
shave lotions, cloth wipes, soaps, creams, and
other products.
Depending upon how a preparation is made witch
hazel products contain varying amounts of active
compounds such as flavonoids, tannins
(hamamelitannin and proanthocyanidins), small
amounts of volatile oil, and other components,
which may be responsible for its astringent action
and to stop bleeding. Tannins have been
characterized as hamamelitannin and a number of
proanthocyanidins. The bark contains 31 times more
hamamelitannin than the leaf extract, so place part
used in preparation is important. In distilled
witch hazel products much of the tannin content is
lost.
A recent study shows there
may be more at work in witch hazel than has been
previously known. A specially filtered fraction of
the extract, containing mostly proanthocyandins,
was found to have significant anti-viral activity
against Herpes simplex virus type 1. The
same fraction was also found to have a strong
antiphlogistic (inflammation-reducing) effect. In
contrast, fractions high in hamamelitannin were
found to have weaker antiviral or antiphlogistic
activity. The significant of this study is that it
shows that compounds other than tannins may play a
role in witch hazel's recognized antiphlogistic
effects, as well as newly recognized topical
antiviral activity. Such studies serve to improve
products available to consumers by helping
manufacturers refine extraction processes to
enhance the best possible therapeutic
results.
Antioxidant,
radiation-protective, and anti-inflammatory
activity have been confirmed. Recently
hamamelitannin and proanthocyanidins isolated from
witch hazel were evaluated for their mechanisms of
action in reported anti-inflammatory activity. It
was found that some proanthocyanidin fractions
inhibit inflammatory mediators derived from
arachidonic acid and inhibited the formation of
platelet-activation factor, a chemical mediator of
inflammatory processes. When it is quelled, so is
inflammation. Strong antioxidant
activity against superoxide (a highly reactive form
of oxygen), released by several enzymes during the
inflammatory process may also play a role in witch
hazel's anti-inflammatory effects. In a recent
study, Japanese researchers sought plant compounds
that protect cells in skin tissue from damage
against harmful forms of oxygen. Witch hazel was
found to have strong activity against reactive
oxygen in skin tissue. The scientists proposed that
witch hazel extracts should be further researched
for their potential application in anti-aging or
anti-wrinkling products to apply to the skin.
Although most herbs are sold in the United States as dietary
supplemenst, witch hazel is one of very few American
medicinal plants still approved as an ingredient in
non-prescription drugs by the Food and Drug
Administration. Witch hazel is approved as an
over-the-counter astringent in the external
analgesic (pain-relieving), skin protectant
categories, and as an external anorectal, primarily
used for symptomatic relieve of hemorrhoids (as
pads, ointments, or suppositories). In Germany, the
bark and leaf are approved for treatment in mild
diarrhea, inflammation of the gums and mucous
membranes of the mouth, and mild irritation or
local inflammation of the skin, hemorrhoids, and
varicose veins. There, witch hazel is considered
astringent, inhibits-inflammation, and locally
styptic.
For over 200 years,
witch hazel has been valued for astringent, tonic,
and mild pain-relieving qualities, used in treating
hemorrhoids, itching, irritations, and other minor
pains. Few clinical studies have been conducted,
but every generation of Americans, since the
formation of the United States, has had witch hazel
preparations in their medicine cabinets. Thanks
