As much as holistic believers and others would like to think that herbal
remedies are harmless they are not. They are
drugs. Just as
acetaminophen (Tylenol) or ibuprofen (Advil) have serious side effects
so does ginkgo biloba or garlic.
Many of today’s medications are chemical duplicates of natural remedies
that were used for years. But mixing standard medications and herbal
remedies is dangerous. For instance, digitalis, a common heart
medication, is actually a chemical duplicate of the substances found in
Foxglove, a common garden flower.
Pharmaceutical companies duplicate the substances so they can control
the quality and quantity of the chemical delivered in each pill. There
has been research that shows that taking the chemicals in their natural
form has better results than those that are duplicated in the lab.
The problems that happen when mixing standard medications and herbal
remedies are called drug interactions. Drug interactions come in three
categories. There are drug/drug interactions, drug/food interactions and
drug/condition interactions. Mixing standard medications and herbal
remedies would fall under the drug/drug interaction category. However,
herbal remedies can also interact with foods or other medical conditions
as well.
Herbal remedies do not fall under the regulatory arms of the Federal
Drug Administration (FDA). This can be both good and bad. Since they
can’t regulate the industry the quality of some supplements can be
called into question. However, on the flip side, if the health food
industry was regulated the range of herbal supplements that really do
work would not be available as the pharmaceutical industry has a vested
interest in people using their duplicated chemicals and not the natural
substances.
According to the May 2005 Annals of Rheumatic Diseases only 25% of
people who took supplements understood there was a potential for a drug
interaction; and 10% of patients taking
NSAIDs increased their risk of
bleeding by taking ginkgo biloba, garlic or devil’s claw.
In drug/drug interactions the medications interact with each other.
These can be prescription, over the counter or herbal. Even vitamins and
Tylenol have the potential to interact with medication you are already
taking. When two
drugs interact the overall
effect may be greater than desired, or less. For instance, certain
antiacids taken with antibiotics decrease the antibiotics effectiveness
by decreasing the absorption into the blood.
Drug/food interactions happen when something you eat or drink interferes
with the medication you are taking. For instance certain foods you eat
will interfere with blood thinners making them less effective or
drinking grapefruit juice may increase the amount of cholesterol
lowering drug in your system. Mixing alcohol with
drugs
is also a dangerous cocktail. The combination can increase your risk of
liver damage, stomach bleeding, slow your reaction time even further or
may you more tired.
Drug/condition interactions happen when a medicine reacts with a
condition. For instance taking decongestants can raise your blood
pressure, which can be dangerous in someone who already has high blood
pressure.
There are specific things you can do to prevent these types of
interactions mixing standard medications and herbal remedies. The first
thing you can do is read the labels on both the standard medications and
the herbal remedies. Second, tell you doctor and/or pharmacist of ALL
the medications you use.
Note: Although your doctor has a broad knowledge of all things medical
your pharmacist as an intensive knowledge of all things medicine. The
pharmacist should be your first line for questions.
Ask you doctor or pharmacist for advice before adding any medication to
your regimen, which includes over the counter medications or herbal
remedies.
Before mixing standard medications and herbal remedies always consult
your pharmacist and you won’t go wrong!
