HERBAL-MEDICAL CONTRAINDICATIONS
by Michael Moore
Synergistic and iatrogenic potentials when certain herbs are used concurrent
with medical treatment or medical health care.
THE REASON FOR THIS LIST:
A list of side-effects written by a toxicologist or a pharmacognosist
will deal ONLY with potential problems that a particular constituent may
cause, and seldom treats a plant as a Gestalt. They don't understand HERBS.
A list of side-effects written by most herbalists will deal with side
effects from over-dosage or adulteration, and will seldom consider the
implications for drug or procedural medicine. They don't understand MEDICINE.
I feel fairly secure in both worlds, so this list of potential synergies
and contraindications is meant to honor BOTH approaches. I am talking
strictly to the working practitioner; these are PRACTICAL concerns, not
theoretical ones.
THE FOCUS OF THIS LIST:
My intent in this list is to wed both approaches:
A. What herbs may present overt drug reactions.
B. What herbs may present synergistic effects to
1. a person undergoing a particular metabolic stress
2. a person undergoing drug therapies
C. What herbs have side-effects BUT that are frequently
used without adequate warnings, marketed with an anti-
medical bias, or taken unwisely by those that feel NO
herb can be harmful because it is natural.
PHILOSOPHICAL CONSIDERATIONS:
If you are used to viewing biologically active agents as analogs to
drugs, you need to suspend those standards when dealing with most herb
preparations. Some of these plants CAN be reduced to the pharmacology
of specific constituents, and they are so noted. The majority of
potential reactions occur when an herb STIMULATES metabolic processes
that are already in an excited state. The usual models of drug toxicology
will fail to predict such reactions; these are NOT, strictly speaking,
drug reactions, but often predictable idiopathic synergies. Predictable,
that is, if you are willing to view most herbs as multi-systemic wholistic
medicines, offering a "profile" of effects that can help OR aggravate,
depending on the PERSON using them.
Herbs should be free of side effects within their therapeutic
window and when used by a person whose constitution is complimented,
not antagonized by the herbs. Whether or not you accept any value to
Botanical Medicine, this is Conventional Wisdom amongst herbalists.
Side effects from herbs are unwanted, both by herbalists wishing to
strengthen, not denigrate homeostasis, and by skeptics who doubt any
value to herbs except from placebo or accidental drug effects.
On the other hand, a careful evaluation of potential drug therapy
starts with the basic understanding that drugs HAVE side effects at the
proper dose, and the value must be weighed against the detriment. Most
possible problems I have listed will only occur in potentiated states,
and may be subtle enough to be ignored by Believers (Don't be so
defensive!), magnified totally out of proportion by Skeptics (Don't be
so judgmental!). We all tend to be too isolated in our peer groups,
always preaching to our particular choir.
Some physicians feel any self-treatment with biologically active
agents is dangerous. Many people consider this either professional
arrogance or the attempt to stifle competition. I have nearly always
observed the attitude to derive from a very real concern; a physician's
biochemical tools are drugs. By extension, docs may rightly presume that
any agent capable of promoting change probably has similar potential for
side effects. Carried to an irrational extreme, some medical folks
feel that anything WITHOUT potential side effects is quackery. This, of
course, leaves any alternative approach in a Catch-22 bind.
There is little intrinsic danger in using herbs, since few have the
potential for DRUG side effects. The side effects are usually
idiosyncratic or idiopathic, and not predictable by drug standards.
This brings me back to why I have assembled this list.
NOTES:
[1] Some of these plants are illegal, not from the pseudo-scientific
rationale of law-inforcement (except Cannabis and Lophophora) but for the
practical legality that THEY AREN'T SAFE. Nonetheless they still find
their way into personal use. I have developed the libertarian attitude
that permeated 19th and early 20th century pharmacy: "Let them take what
they want to...it's a Free Country. If they don't know any better, let's
thin the herd!". We, however, have a generation or two of people that
EXPECT a warning label on everything, and that have come to doubt common
sense. Of course many dangers in modern life do not warn by taste, smell
or appearance...radiation, pollution, etc. Given this, plant drugs like
Yohimbe and even Ma Huang should, in my opinion, not be available in the
same marketplace as Peppermint and Sarsaparilla. But they are.
[2] Some of these herbs are only encountered in "ethnic" use, but, with
most ethnic groups suffering diminished coherence of tradition, a Wise
Woman or folk herbalist may not be around to give appropriate advice.
[3] A few of these herbs are seldom encountered in the herb trade but
rather are wildcrafted and used inappropriately. Some of this may be MY
fault, since I write about the use of plants that are low-dosage
botanicals and presume that the reader has Common Sense...not always a
reality. Many of us distrust ANY authoritative limits...this antiauthor-
itarianism may be encountered in the way some people use even sensible
herb books.
[4] Herbal Cure-Alls and thinly-veiled Phytopharmaceuticals are a growing
part of the health-food industry. In Europe they are usually dispensed
under medical supervision; they have no place in American Standard
Practice but instead have entered the alternative health marketplace as
"Herbs". They are more concentrated, more refined, have little of the
biochemical buffering or "fuzz" that whole plants offer, and are NOT
metabolic tonics but substances intended for specific subclinical
pathologies...Little Drugs if you will. Their use is intended for
conditions that have been medically diagnosed...not for self-treatment
based upon sometimes inaccurate self-diagnosis. It's one thing to take
aspirin for a headache or use a bitter to trigger improved upper digestive
function. It's another thing to take proven immunostimulant or anti-
oxidant substances (even if derived from plants) if based on "I get sick
a lot" or "I bet my liver needs cleansing".
Not only is this an entirely new realm of potential iatrogenesis, but
it has a corruptive influence by my way of thinking. It centralizes the
MARKETING of herbs into the hands of a few, but without offering guide-
lines for DIAGNOSIS. And it seduces folks from the sensible heart of
self-treatment...self-knowledge.
One-size-fits-all is not self-empowerment

PREGNANCY
Some of these herbs are relatively harmless, but considering the highly
reactive state of pregnancy, and the fact that fetal growth is a template
that can manifest pharmacokinetics VERY differently than for an adult,
they are mentioned. Others are obviously inappropriate because of their

HERB-SPECIFIC PROBLEMS
HERBS WITH MISCONCEPTIONS:
ALETRIS FARINOSA (Star Grass, "True" Unicorn Root) Confused with
Helonias (Chamaelirium), an HCG agonist and reproductive stimulant. Aletris
is only a digestive stimulant
ANGELICA SINENSIS (Dong Quai, Tang Kwei) NOT a source of exogenous estrogen, it instead
increases utilization of ENDOGENOUS estrogens
ARNICA (A. montana. A. cordifolia, A. latiflora. etc.) Unsafe for internal use, it can be confused with
HETEROTHECA (Mexican Arnica)
CAPSICUM (Cayenne, African Bird Peppers)
Not a tonic or immunostimulant, it acts as a peripheral vasodilator, increasing
blood supply to the skin and mucosa. It is NOT appropriate for active inflammation.
CEREUS GRANDIFLORUS (Selenicereus, Peniocereus, Night-Blooming Cereus)
NOT a digitalis-like cardioactive, it moderates SA-AV depolarization and lessens adrenergic
or drug tachycardia. NOT for organic disease
CORYNANTHE (Pausinystalia Johimbe, Yohimbe)
An especially pernicious herb with simultaneous sympathetic
AND parasympathetic actions. It will mimic vasopressin and can irritate
the kidneys; it increases pelvic blood supply and can aggravate reproductive,
GU, and descending colon irritations; it can irritate arterial endothelium
and contribute to or cause vasculitis. Lousy for the prostate, it CAN trigger
a few and relatively useless erections, followed by rebound re-flaccidity.
DIOSCOREA VlLLOSA (Wild Yam) It has NO PROGESTERONE, or any other steroid
hormone. The first generation of synthetic steroids was made using diosgenin
(from MEXICAN Yam) and the Marker Degradation Method. By the mid-1950's
stigmasterol (a soy-derived lipoid) took its place, and other methods are
now used. It contains NO "precursors"...the only true human steroid
precursor is low-density cholesterol OR some other steroid hormone. Wild
Yam creams usually contain synthetic Natural Progesterone.
EPHEDRA VULGARIS
(Ma Huang, Chinese Ephedra) Although a useful and less edgy source of ephedrine,
it is almost totally used these days as an "anorectic" or "safe"
stimulant. Most people view CNS stimulants by comparison with caffeine
sources...a 3-4 hour buzz. Ephedrine lasts 7-8 hours, is more adrenergic,
and it is easy to overlap the dose addition, with extended serum levels,
tolerance to CNS effects can be quick (although other effects stay somewhat
level) and an individual can quickly creep up in dosage. Dangerous in this
context.
GINKGO BILOBA (Maidenhair Tree) A peripheral and cerebral vasodilator,
it helps those with impaired circulation. It is often sold, however, as
an aid to "intelligence" and is often used by students when cramming
for tests, etc. Under these misguided uses it causes many headaches
HETEROTHECA (Camphor Weed, Mexican Arnica) See ARNICA HYPERICUM (St. John's Wort)
Several preliminary tests implicated it as an anti-viral for HIV. These were overturned
in subsequent tests but the reputation still lingers. It IS useful for
helping some of the CNS symptoms of AIDS, but because of it's antidepressant
effects, NOT because it is antiviral.
LARREA (Chaparral, Gobernadora, Creosote Bush)
It should not be considered as a liver irritant, despite several
inexplicable cases. It IS an hepatic depressant (excessive antioxidant
activities) and CAN cause hemolytic-type responses if it is used well above
it's therapeutic window.
LOBELIA INFLATA (Lobelia, Indian Tobacco)
Fresh preparations of this herb show broad, many-layered stimulus of adrenergic-suppressed
parasympa- thetic functions. Dry, but unheated Lobelia retains some of
this function. By the time it is used for tea ONLY the emetic alkaloids
are still intact, and it has little other value.
PHYTOLACCA (Poke)
Although useful (with a skillful touch) in depressed metabolism and edematous adipose
tissues (the "Pillsbury Dough Person" syndrome), it has NO fat-reducing
effects, is easily toxic, and it's reputation comes from being used for
hypothyroid, goitrous conditions 100 years ago...in the Goiter Belt.
SENECIO AUREUS (Life Root, Squaw Weed) This native Eastern United States
wildflower seems to be beneficial for functional hypoestrogenic states, and has a
reliable place, at least in herbal therapy. It is also fairly unique as
a Senecio: it is devoid of toxic pyrrolizidine alkaloids. MOST of the herb
on the market, however, is either S. vulgaris or a similar Senecio. I don't
know how the confusion came about. They are not particularly similar in
appearance, but many otherwise reliable texts consider them interchangeable.
In fact they are VERY dissimilar in constituents. The OTHER Senecios are
VERY high in the toxic group. Know the plant or the picker, otherwise avoid
this remedy and stick with something like Dong Quai.
SILYBUM MARIANUM (Milk Thistle)
There are HUNDREDS of reliable biologic and medical studies that
support this plant's seeds' value for Amanita mushroom poisoning, lessening
the toxicity of heavy metals (if taken soon enough) and quickening CNS
and hepatic regeneration in solvent or alcohol detox. Like Ginkgo, however,
you NEED a problem to get benefit. Without an ongoing stress, using Silybum
or it's extracted silymarins on general principle can actually depress
normal liver function
VISCUM ALBUM (European Mistletoe)
Without attempting to comment on the European use (from the Rudolph Steiner hospitals)
of Mistletoe (I don't know enough), the fact is that the dried herb is SOMETIMES
not European but American Mistletoe (Phoradendron spp.), a VERY different
plant altogether (at least pharmacologically), with almost pernicious vaso-constrictive effects.
HERBS WITH HIDDEN or THRESHOLD EFFECTS
CANNABIS SATIVA (Marijuana. Hemp) It can be a strong estrogen-synergist,
shortening the estrus cycle in women, antagonizing testosterone in men
(or being synergistic with adipose estradiols)...bad for any prostate condition.
DAUCUS CAROTA (Carrot, Wild Carrot) Sometimes used as a contraceptive,
it contains aromatics that, in large enough quantities, can exaggerate
uterine inflammation.
EQUISETUM ARVENSE (Horsetail) If growing in areas
downstream of commercial farming, inorganic nitrates are metabolized into
abnormal nicotine- like alkaloids.
HYDRASTIS (Golden Seal) A mucus-membrane
stimulant, useful for congested and subacute stages, it can CAUSE inflammation
if not needed, can prematurely age the placenta, and, since it is threatened
in the wild and cultivation is still marginal, its use is rarely moral.
VALERIANA (Valerian) The dried plant, used consistently for a period of
time, can induce "Valerianism", a state of emotional lability
similar to what was formerly encountered with bromide abuse. The condition
reverses quickly if the Valerian is stopped.
HERBS LACKING ANY SOCIALLY REDEEMING VALUE
ARTEMISIA ABSINTHIUM (Wormwood)
CINCHONA (Peruvian Bark. Quinine Bark)
CORYNANTHE (Pausinystalia Johimbe, Yohimbe)
EPHEDRA VULGARIS (Ma Huang. Chinese Ephedra)
GALEGA (Goat's Rue) RUTA GRAVEOLENS (Rue, Ruda) TANACETUM (Tansy)
POST NOTE: These opinions are mine; they reflect my experiences
with these plants, as a merchant, wildcrafter, author and teacher. They
are not exhaustive, many are disagreed with by other herbalists, naturopaths
and those in pharmacy...I have enemies in ALL the camps. Crudely put, there
is no better method to "Brown Nose" a group of medical professionals
than by offering long lists of "Side Effects", thereby confirming
their worst fears about what herbs do. The major medical journals (NEJofM
and Lancet excluded) jerk the chains of readers by offering ill-researched,
anecdotal and slanderous "exposes" of herbs and natural healing,
using the shoddiest of peer-review procedures. Not only are there frequent
REAL mistakes (wrong botany, pharmacy, etc.), but the normally fastidious
standards of medical reporting are completely ignored in many of these
articles. It is as if the MEANS are unimportant, as long as the RESULTS
meet political-medical preconceptions. Politics be damned; there are potential
dangers mixing herbs and medicine. Unfortunately, as previously mentioned,
they often have little relationship to those that could be expected from
purely chemical causes. I am trying to be practical and realistic. Although,
as an herbalist, it is obvious where my heart lies, I am making NO attempt
to slant my list towards either end of the Wholistic vs Medical dialectic.
I am concerned about the patients.
