Chapter 5: Complementary & Alternative Therapies in Care

Welcome to Last Minute Lecture.

This free chapter overview is designed to help students review and understand key concepts.

Welcome back to another Deep Dive.

Today, we are doing something that feels a little bit like we're stepping out of the sterile hospital environment and into, well, maybe a garden, or perhaps an old world apothecary shop.

We are tackling a subject that is absolutely massive, often misunderstood,

and honestly a little bit controversial in the rigid world of Western medicine.

It is a huge topic, and it's one where the lines between food, culture, and medicine get very, very blurry.

We are looking at Chapter 5 of Pharmacology, a patient -centered nursing process approach, the 12th edition.

The title of the chapter is Complementary and Alternative Therapies.

I have to say, looking at the source material, this feels less like a chemistry class and more like a walkthrough, a very confusing, potentially dangerous, but also fascinating landscape.

It is a landscape that every single nurse has to learn how to navigate.

I say navigate because you can't just ignore it.

You can't just pretend it doesn't exist.

Exactly.

Here is the statistic that really grabbed me right at the start of this chapter.

I think this sets the stage for everything we're going to talk about.

The text says that approximately 40 % of adults use some form of complementary and alternative medicine, or CAM.

That is nearly half the population.

That is the hook right there.

Think about that for a second.

If you are a nurse working on a medsurg floor or in a clinic or in the ER, almost every other patient you walk in to see is going to have something in their system that isn't a standard prescription drug.

It might be a tea.

It might be a vitamin stack.

It might be a tincture they bought at a farmer's market.

And usually they don't tell you about it.

Right.

They don't consider it medicine, but chemically.

It's absolutely medicine.

And if you as the nurse don't know what those things are or how they interact with the anesthesia you're about to administer or the blood thinners the doctor just prescribed, you have a massive safety gap.

So that is our mission for this deep dive.

We are going to navigate this wild west of herbal supplements.

We need to understand the regulations, or maybe the lack of regulations is a better way to put it.

We need to break down the physics of how these things are made because apparently the difference between a tea and a tincture actually matters for safety.

It matters immensely.

And then we are going to do a serious A to Z roll call of the specific herbs that are most likely to show up on a nursing exam or in a patient's history.

We're going to separate the marketing from the science.

And the red thread running through this entire discussion, the thing I want everyone to keep in the back of their minds is safety.

We need to dismantle this idea that natural equals safe.

That is probably the most dangerous marketing slogan in healthcare history.

Arsenic is natural.

Snake venom is natural.

These plants we're discussing are chemically active substances.

They require the same respect as a loaded syringe.

Okay, let's unpack this.

The chapter starts by defining the landscape.

We use this term CAM, complementary and alternative medicine.

It seems like a broad bucket.

What exactly does that cover in the context of this specific pharmacology text?

It is a broad bucket.

So CAM includes things like physical therapy, massage, prayer and meditation.

But for the purpose of a pharmacology course in this chapter specifically, we are focusing on the biologics.

We are talking about botanicals, nutritional products and herbal supplements.

The text defines CAM as therapies used to augment, that's the complementary part, or replace, that's the alternative part, traditional medical therapies.

So if I take fish oil with my heart meds, that's complementary.

If I stop taking my heart meds and only take garlic, that's alternative.

Exactly.

And that distinction changes the risk profile significantly.

Now the text makes a distinction here that I think is interesting between a botanical and an herb.

I always thought those were synonyms.

I mean I use them interchangeably all the time.

Most people do.

But technically there's a nuance.

An herb is specifically a plant that is used for culinary or medicinal purposes.

Think of the basil in your pesto or the chamomile in your tea.

It's the plant itself.

A botanical is a broader term for an additive substance that comes from a plant.

So if you extract a specific chemical compound from a tree bark to put into a pill, that's a botanical additive.

Okay, so botanical sounds a bit more processed maybe, more scientific.

Often, yes.

It implies it's being used as an ingredient or an additive rather than just the whole plant.

Now this brings me to my first big aha moment reading the source material.

I think there is a tendency, especially in modern hospitals, to view herbal medicine and real medicine as enemies.

You know, like science versus superstition.

But the text points out that a huge chunk of our modern pharmacology actually comes from plants.

Oh, absolutely.

This is what we call phytomedicine, the therapeutic value of plants.

It is the basis for much of modern pharmacology.

We didn't just invent drugs out of thin air in a lab.

Usually we found them in nature first, realized they worked, and then figured out how to synthesize them or extract them efficiently.

The text lists some classic examples that really drive this home.

I think every nursing student knows digitalis.

Digitalis is the classic example.

The drug is digoxin.

It's a cardiac glycoside used for heart failure.

It slows the heart rate and makes the contraction stronger.

It comes from the foxglove plant.

Which is a beautiful flower you see in gardens all the time.

It is, but if you just ate the flower, you'd probably die of cardiac arrest.

That's the power of the plant.

We refined it into a life -saving drug by standardizing the dose.

What about snakeroot?

That one sounds ancient.

Right.

Snakeroot gave us reserpine.

That was one of the first antihypertensives and antipsychotics.

It's rarely used now because of side effects, but it was a breakthrough that came from a root.

And aspirin.

I think most people know this one.

Willow bark.

People were chewing on willow bark for pain relief and fever reduction for centuries.

The active ingredient is salicin, which converts to salicylic acid.

Bayer eventually synthesized it into a salicylic acid aspirin to make it easier on the stomach, but the origin is the tree.

And the one that really surprised me was paclitaxel.

That's a heavy -duty chemotherapy drug.

It is.

It's used for ovarian, breast, and lung cancers, and it was originally derived from the bark of the pacific yew tree.

So the argument isn't that plants don't work.

It's almost the opposite.

No, not at all.

The argument is that they work so well that they are essentially drugs.

And because they are drugs, they have side effects, they have toxicities, and they have interactions.

If a plant is strong enough to kill a cancer cell or strong enough to stop a heart arrhythmia, it is certainly strong enough to damage your liver if you take it wrong.

That validates phytomedicine, but it also warns us about it.

And clearly people believe in that power.

The text mentions this is a huge industry.

Over $6 billion annually and growing.

It's a massive market.

But unlike the paclitaxel or the degoxin in the hospital pharmacy, the stuff sold at the health food store seems to operate by a different set of rules.

We need to talk about the laws, because this is where it gets confusing for patients and for us.

It is the most complicated part of this deep dive, the regulatory landscape, because these herbs exist in a regulatory gray area.

The text focuses heavily on the DSHEA, the Dietary Supplement Health and Education Act of 1994.

This seems to be the watershed moment.

It is the defining piece of legislation in the United States.

Before 1994, it was a bit murky how these things should be categorized.

Were they food?

Were they drugs?

DSHEA officially defined the term dietary supplement.

How does it define it?

What's the official line?

It says a dietary supplement is a product intended to supplement the diet.

It contains one or more dietary ingredients like vitamins, minerals, herbs, or botanicals.

It's intended to be taken by mouth, so not injected.

And it is labeled as a dietary supplement.

Okay, that sounds official.

But here is the part that scares me.

And I want you to clarify this for the listeners.

If I buy a bottle of antibiotics, I know the FDA has dragged that through Phase 1, Phase 2, and Phase 3 clinical trials.

They've spent millions of dollars and years proving it's safe and effective before it ever touches a shelf.

Does a supplement company have to do that under DSHEA?

No.

And this is the critical safety gap.

Under DSHEA, dietary supplements are regulated by the FDA, but the oversight is limited compared to prescription drugs.

Manufacturers do not, I repeat, do not have to demonstrate product safety or efficacy before the product is sold.

Wait, really?

They can just put it on the shelf?

Essentially, yes.

The manufacturer is responsible for ensuring the product is safe, but they don't have to submit proof to the FDA before marketing it.

The FDA usually only steps in after the product is on the market and people start reporting problems.

It is a reactive system, whereas drug regulation is a proactive system.

That is a wild difference.

Basically, the general public is the clinical trial.

In a way, yes.

And this lack of pre -market testing leads to a lot of confusion about what products can actually claim to do.

This brings us to the claims loophole.

I noticed this in the text.

There's a very specific set of rules about what the label can and cannot say.

It's like a word game.

Right.

And for nurses, this is crucial to understand so you can explain it to patients who might be misled by marketing.

Under the law, manufacturers cannot make claims about diagnosing, treating, curing, or preventing a disease.

Those are medical claims.

So you will never see a legal label that says cures heart disease.

Correct.

That would get them shut down immediately.

You also can't say treats diabetes or prevents cancer.

But they can say things that sound very, very similar to that.

Exactly.

They are allowed to make what are called structure function claims.

They can say the product affects the structure or function of the body.

So instead of cures heart disease, they can say supports healthy heart function or helps increase blood flow to the heart.

Or instead treats diabetes, they could say helms maintain healthy blood sugar levels.

Right.

Or alleviates occasional hot flashes.

Note the word occasional.

They can't say cures menopause because menopause isn't a disease to be cured.

But hot flashes is a symptom they can claim to alleviate.

It's a linguistic dance.

It's all about implication.

It is.

And it allows them to imply a benefit without legally promising a cure.

And this is why every single bottle you pick up has that box with the famous disclaimer, the one in tiny print.

This statement has not been evaluated by the FDA.

This product is not intended to diagnose, treat, cure or prevent any disease.

Do patients actually read that box or even understand what it means?

In my experience, rarely.

They look at the big font that says brain booster or immune shield and they assume it works.

They assume that if it's in a pharmacy, someone checked it.

So if the FDA isn't checking every bottle before it ships to see if it works, are they at least checking what's inside?

I mean, how do we know the ginseng pill isn't just sawdust?

That has been a historical problem adulteration.

But there was a step forward.

In 2003, the FDA implemented the CGMP's current good manufacturing practices.

Okay.

CGMPs.

What does that cover?

These are multifaceted standards.

They require that package labels accurately reflect the quality and strength of the contents.

They require the product to be free of contaminants like lead, pesticides, bacteria, or even glass.

It's about manufacturing hygiene and truth and labeling regarding the ingredients.

Okay.

So that's a floor for quality.

It means the factory isn't dirty and the label shouldn't lie about the contents.

It's a baseline.

But since the FDA can't inspect every facility every day, there are private organizations that have stepped in to do testing.

You might see seals of approval from organizations like the USP, which is the US Pharmacopeel Convention, Consumer Lab, or NSF International.

Okay.

Let's talk about those seals.

If a patient brings in a bottle with a USP verified seal, what does that actually tell me?

Does it mean the herb works?

No.

And this is a nuance we have to hammer home.

Those seals verify identity and purity.

They confirm that if the label says 100 milligrams of ginseng, there is actually 100 milligrams of ginseng in the pill.

They confirm it dissolves properly in the stomach.

They confirm it's not full of mold or arsenic.

But there's a big but coming.

I can feel it.

But the seal does not guarantee that the ginseng will actually help your energy levels.

And crucially, it does not guarantee that it is safe for you personally to take.

It doesn't warn you about interactions with your other meds.

Purity does not equal efficacy, and it certainly does not equal safety.

That is a vital distinction.

So a USP seal means this is high quality ginseng, not this ginseng will save you.

Precisely.

It's a quality control stamp, not a medical endorsement.

The text also mentions a newer group, the Botanical Safety Consortium.

What's that about?

Yes.

Established recently in 2019, it's a partnership between the FDA, the NIH, and industry groups.

Their goal is to improve the science of safety testing for botanicals, basically trying to create better toxicology tools.

It shows that the industry knows safety is a blind spot and they are trying to fix it.

It's a step in the right direction.

Let's move from the legal side to the physical side.

I love the image the text describes in the section on forms of herbal preparations.

It mentions dried herbs hanging in bundles, a mortar and pestle, glass bottles.

It feels very old school apothecary.

It does, but we have to understand that the form matters.

You can't just document patient takes echinacea.

The form dictates the potency and how it's absorbed.

A cup of tea is very different from a concentrated alcohol extract.

Let's run through the definitions in table 5 .1 because these terms come up a lot on labels.

Start with a decoction.

A decoction is basically a tea, but it's made from the tough parts of the plant.

Think bark, roots, woody stems.

Because those parts are hard, you can't just pour water over them.

You have to boil them in water for a specific time to break down the material and extract the medicine.

Versus an infusion.

That sounds more familiar.

An infusion is what you think of when you make a cup of Earl Grey.

You're using softer parts, flowers, leaves.

You pour boiling water over them and let them steep.

You don't boil the leaves directly usually because the heat might destroy the volatile oils.

So decoction equals boil the hard stuff.

Infusion equals steep the soft stuff.

Got it.

Then we have tinctures.

I see these in little dropper bottles at the store.

They seem potent.

A tincture is much more concentrated.

You take the herb and soak it in a solvent, usually alcohol, vinegar, or glycerin, for anywhere from two to six weeks.

The liquid pulls the active compounds out of the plant material because it's concentrated.

You usually only take a few drops, not a whole cup.

And the alcohol X is a preservative too, right?

So they last a long time.

Correct.

It gives it a long shelf life.

What about when we put stuff on our skin?

The text mentions a liniment and a poultice.

A liniment is an extract added to alcohol or vinegar that you rub on the skin.

Think of those muscle rubs that smell strong and feel warm.

A poultice is more rustic.

It's a moist mass of the actual plant material, like crushed leaves or roots wrapped in cloth and strapped directly onto the skin.

It's used to dry out infection or reduce swelling.

And then the big one everyone knows, essential oils.

Right.

These are aromatic volatile oils extracted from the plant.

They are incredibly concentrated.

The text implies a safety warning here.

Usually these are for aromatherapy or topical use, and they typically need to be diluted in a carrier oil.

You don't usually drink these.

Swallowing undiluted essential oils can be toxic and burn the mucosal lining of the GI tract.

And finally, there's a term here I hadn't heard before, percolation.

It sounds like making coffee.

It's physically very similar to making coffee.

It's an extraction process using gravity.

You pack the ground plant material into a cone -shaped vessel.

You pour the liquid solvent, which is technically called the menstruum over the top.

Menstruum.

That's a new word for me.

Yes.

M -E -N -S -T -R -U -U -M.

That's the liquid solvent.

It trickles down through the plant material, picking up the chemical constituents along the way, and drips out the bottom.

The solid stuff left over the wet grounds is called the mark, which you throw away.

Menstruum and mark.

Good vocab words for the exam.

So, understanding these forms really helps a nurse figure out the dose, basically.

Absolutely.

It helps you understand how much of the active ingredient a patient is actually getting.

It's a huge piece of the puzzle.

Okay, let's get into the meat of the chapter, the roll call.

The text provides a list of commonly used herbal remedies.

We need to go through these A to Z, because this is what nurses will see on medication lists.

For each one, we want to know, what is it used for?

What does the evidence say?

And crucially, what are the safety warnings?

Let's do it.

First up, Asian ginseng.

Pinax ginseng.

Very popular.

It's used for stress relief, boosting the immune system, and physical stamina.

People take it to feel more on, you know, for energy.

Does it work?

Is there good evidence for that?

The evidence is shaky.

There are some studies suggesting it might improve glucose metabolism, helping with blood sugar control, but the text notes, they aren't high quality.

So the jury's still out on its effectiveness.

And the safety alert.

What's the danger here?

There are a few.

First, diabetics need to be very careful, because it can lower blood sugar.

If you take it with insulin or other oral hypoglycemyx, you risk hypoglycemia, dropping the blood sugar too low.

It also interacts with calcium channel blockers.

Those are blood pressure meds and warfarin, which is a blood thinner.

And insomnia, right.

Since it's sort of a stimulant.

Correct.

Taking it at bedtime is a bad idea.

It can definitely keep you awake.

Next on the list, chamomile.

The classic sleepy time herb.

Used for sleeplessness, anxiety, and GI upset.

I feel like this is one almost everyone has in their cupboard.

It feels so harmless.

It is very common.

And the evidence is actually decent for generalized anxiety disorder.

And for kids mixed with other herbs, it can help with colic or upset stomach.

But here is the safety flag that surprises people.

Allergies.

Really?

You can be allergic to chamomile tea.

Yes.

Chamomile is in the Asteraceae family.

It's a cousin to ragweed, daisies, and chrysanthemums.

If a patient have a bad ragweed allergy, hay fever, chamomile can trigger a cross reaction.

It can range from hives to bronchospasm, or potentially even anaphylaxis in rare cases.

That is a great catch.

I would never have hay fever with a cup of tea.

Next,

echinacea.

The cold and flu go -to.

People take it to stimulate the immune system to ward off colds.

Does it actually stop a cold?

The text says it might slightly reduce your chance of catching a cold.

It's not a miracle cure, but there's something there.

The evidence is modest.

Is it safe?

Generally yes for short -term use.

The text is clear that long -term safety is uncertain.

It can cause some GI side effects like nausea

Moving on to garlic.

People eat this, so it must be safe, right?

In food amounts, yes.

But as a supplement, people take high concentrations to lower cholesterol and clud pressure.

The evidence supports a slight reduction in cholesterol and LDL, and maybe a little help with BP.

But there's a surgical warning here, which sounds serious.

Big time.

Garlic affects clotting.

It inhibits platelet aggregation.

That creates a bleeding risk.

If a patient is heading for surgery or even dental work, they need to tell their provider and stop the garlic beforehand.

And there is a specific drug interaction mentioned that is super specific but critical.

Sequinovir.

That's an HIV medication.

It's a protease inhibitor.

Garlic reduces the effectiveness of sequinovir.

It induces the metabolism, clearing the drug too fast from the body.

So a patient trying to be healthy by taking garlic supplements could actually cause their HIV treatment to fail.

That is a massive interaction.

That is scary.

That could be a life -or -death interaction.

Okay, Ginger.

Used for nausea.

Pregnancy nausea, chemo nausea, motion sickness.

It's very popular for that.

Does it work?

For pregnancy, nausea, morning sickness, short -term use is effective, and the research supports it.

For motion sickness or chemo, the jury is still out.

The results are inconclusive.

Side effects?

Anything major?

Mostly just gas and bloating.

Pretty mild compared to the others we've discussed.

Now here's a big one.

Ginkgo.

Ginkgo biloba.

Everyone's grandparent takes this for memory, right?

It's the brain herb.

People take it for dementia, memory improvement, anxiety.

But here's the headline the text gives us.

The big letdown.

A letdown?

Why?

Yes.

There was a massive study, the GM study, that followed 3 ,000 older adults.

It showed Ginkgo neither prevented dementia nor cognitive decline.

Wow.

So all those bottles sold for memory.

Not backed by high -quality science, according to this text.

It might help a little with peripheral artery disease or glaucoma because it helps blood flow, but the brain claims are weak.

And the safety risk is, once again, bleeding.

It interacts with anticoagulants.

That seems to be a theme.

The G, herbs, garlic, ginger, ginkgo, ginseng, all seem to increase bleeding risk.

That is a fantastic mnemonic for students.

The four Gs mean bleeding risk.

Watch out for warfarin, aspirin, and surgery.

Okay, let's flip to the second half of the alphabet.

Lavender.

Mostly used for anxiety, depression, relaxation.

Small studies show some benefit for anxiety.

It's generally safe in food amounts or as aromatherapy.

Just be careful with direct skin application of the oil.

It can cause a rash if it's not diluted.

Saw palmetto.

This is huge for men's health.

Right.

For BPH benign prostatic hypertrophy.

Older men take it to help with urinary symptoms, like having to pee constantly at night.

Does it work?

The text is pretty brutal here.

It says research shows it is no more effective than placebo.

Ouch.

So it's the placebo effect.

Any benefit they feel is just in their head?

According to the text, yes.

It's well tolerated.

Side effects are mild.

But it likely isn't actually shrinking the prostate or improving urine flow in a meaningful way.

Now we arrive at the one I call the nightmare interaction herb.

St.

John's wort.

This is the one every nurse must remember.

If you remember nothing else from this list, remember St.

John's wort.

It's used for depression.

They call it nature's pro vac.

Does it work for depression?

The evidence is mixed.

It might help mild depression.

But the text says it's no better than placebo for moderate or severe depression.

But the interactions.

Oh boy.

Let's list them.

Why is it so dangerous?

What's the mechanism?

It messes with the liver enzyme, specifically the

system.

It induces them, meaning it puts them into overdrive.

This makes your body metabolize other drugs too fast.

So if you are taking other meds, St.

John's wort flushes them out of your system before they can work.

So what drugs does it run?

The list is long.

Birth control pills.

It can cause unintended pregnancy because it metabolizes the hormones too fast.

Cyclosporine.

That's an organ anti -rejection drug.

Imagine losing a kidney transplant because you took a supplement for your mood.

Digoxin, warfarin, seizure meds.

It interferes with so many critical medications.

And what if you take it with an antidepressant, like an SSRI?

Then you risk serotonin syndrome.

Because St.

John's wort increases serotonin, if you combine it with an SSRI like Prozac or Zoloft, you get way too much serotonin.

That can cause fever, muscle rigidity, seizures.

It can be life -threatening.

St.

John's wort is not something to play around with.

It really sounds like it should be a prescription drug with that many interactions.

Okay, last one on the roll call.

Turmeric.

Used for inflammation and arthritis.

The problem here is bioavailability.

The active ingredient curcumin is very unstable and hard for the body to absorb.

So there isn't a lot of strong research proving it works simply because it's hard to get it into the bloodstream in high enough amounts to have a real effect.

It's safe in moderate food -like amounts, though.

So that's our roster.

But we need to zoom out and talk about the general hazards.

The text has a section called Hazards of Herbals, and the subtitle is Natural Does Not Mean Safe.

We've touched on this, but let's look at the disclosure problem.

Patients don't tell nurses they're taking these things.

They fear judgment, or they just don't count them as meds.

So they list their metformin and their lists in opryl, but forget the three herbal teas and the garlic pills and the tincture their aunt gave them.

Exactly.

And that's where interactions happen.

We talked about St.

John's wort inducing enzymes, making drugs less effective.

But look at Goldenseal.

It's a potent inhibitor.

That's the opposite.

It slows down the liver's ability to process drugs.

So drugs stay in the system too long and can become toxic.

Right.

Which can lead to toxicity.

If you are on a drug with a narrow therapeutic index, Goldenseal could push you into overdose territory just by preventing your body from clearing the This is really specific, but so important.

It brings up digoxin levels.

Yes.

Two Chinese herbs, Danshan and Shansu, can interfere with the lab test, the assay used to measure digoxin levels in the blood.

They can make the test give a false reading.

If a patient is on digoxin, they absolutely must avoid these, or the nurse will be making dose decisions based on bad data.

And then there's the route of administration.

The example given is comfrey, which sounds terrifying.

Comfrey is a great example of location, location, location, used externally as an ointment.

It's great for sprains and swelling,

but used internally, taken by mouth.

It contains purelazodine alkaloids that cause a veno -occlusive disease in the liver.

It can be fatal.

Fatal from an herb.

Fatal.

Severe, irreversible liver damage.

So if a patient says, I'm using comfrey, the nurse's next question must be, how are you using it?

The route is everything.

We've mentioned surgery a few times, but let's codify the rule.

The American Society of Anesthesiologists has a guideline.

The rule of thumb.

Discontinue all herbal therapy two to three weeks before surgery.

Why so long?

That seems like a lot of time.

You need to wash these compounds out of the system completely.

They interfere with anesthetics, meaning you might not stay asleep properly, or your blood pressure could crash.

And they interfere with clotting.

We already listed the herbs, but also feverfew, donkwai, and even chamomile can affect bleeding.

You don't want to surprise hemorrhage on the operating table.

And there's a little gray box in the text about COVID -19.

What does it say?

Yes.

It's an explicit disclaimer.

No herbs have been shown effective for preventing or treating COVID -19.

Period.

Full stop.

Clear enough.

So we have all this knowledge.

How do we apply it?

This brings us to section seven, the nursing process.

It starts with assessment recognizing cues.

The nurse needs to ask the right questions.

Instead of saying, do you take drugs?

Which sounds accusatory.

Ask, what are you taking to stay healthy?

Do you drink any herbal teas?

Who recommended them?

Ask open -ended, non -judgmental questions.

The text suggests the brown bag method.

It's the gold standard.

Ask the patient to put everything they take, pills, vitamins, teas, tinctures, old bottles from the back of the cabinet into a brown bag and bring it to the clinic.

Then you go through it item by item.

You get so many things this way that aren't on the official chart.

And we need to be culturally sensitive when we do this.

Absolutely.

Many of these remedies are deeply rooted in cultural traditions.

If you dismiss them as nonsense, you lose the patient's trust immediately.

You need to ask, who recommended this?

How long have you been taking it?

Understand the why.

You are there to guide, not to judge.

Then we move to planning and interventions.

Education seems to be the main intervention here.

It is.

We teach them to read labels, look for that USP seal for purity.

We teach them about consistency.

Because manufacturing varies, we advise patients to stick to one brand.

If they switch brands of St.

John's wort, the potency might change completely, and suddenly their drug interactions change.

And we need to teach about food and herb interactions too.

Right.

Just like with prescription meds, some foods enhance or diminish the action of herbs.

And of course, tell them to report any side effects immediately.

Let's apply this clinical judgment with a case study.

The text gives us a scenario about a 55 -year -old with type 2 diabetes.

This is a classic scenario.

He is prescribed metformin, 500 milligrams, but he admits he never frumped it.

Instead, his neighbor told him to use cinnamon.

Because Google said it lowers blood sugar.

Exactly.

So he's taking a heaping spoonful of baking cinnamon in his tea every morning.

What is the problem here?

I mean, cinnamon is tasty.

Is it really that bad?

The problem is threefold.

One, baking cinnamon, which is usually cassia cinnamon, is not a standardized dose.

A heaping spoonful is not a measurement.

Two, high doses of cassia cinnamon contain coumarin, which can be toxic to the liver.

But the biggest problem is replacement.

He's replacing a prescribed, proven medication like metformin with a spice without consulting the provider.

His diabetes is currently uncontrolled.

So as the nurse, do you scold him?

Stop that.

Take your pill.

No, that shuts down communication.

First, assess.

What are your blood sugar readings?

How are you feeling?

Then, education.

You explain that while some studies on cinnamon exist, it is not a substitute for metformin.

You explain the risks of uncontrolled diabetes, nerve damage, kidney failure.

You try to bring him back into the therapeutic plan without making him feel stupid.

It's about being a partner in their health, not a dictator.

Precisely.

Maybe he can keep the cinnamon in his tea in a smaller amount if he also takes the metformin, assuming no interactions.

But he needs to know that the cinnamon alone isn't doing the job.

This has been quite a journey through the pharmacy aisle.

Let's wrap this up with a quick fire review.

I'm going to throw some concepts at you from the review questions, and you give me the key takeaway.

Hit me.

D .S .H .E .A.

1994 Act.

Reclassified herbs as dietary supplements allows suggested dosages but forbids claims of curing disease.

And the big one,

no pre -market safety testing required by the FDA.

Action step.

A patient lists four herbal supplements.

What do you do first?

Inform the provider, get the full list on the chart, then immediately check those supplements for interactions with their prescribed medications.

Anticoagulants.

Which herbs are the enemies?

The G -Force, garlic, ginger, ginkgo, ginseng, fever, fuel, and licorice.

They all increase bleeding risk.

Stop them before surgery.

Garlic specifically.

What's the summary?

Good for cholesterol, maybe BP,

bad for dental work because of bleeding, and a potentially deadly interaction with HIV meds like sequinavir.

You nailed it.

I try.

It's a lot to remember.

So what is the final thought for our listeners today?

We've covered a lot of chemistry and law.

I think the final thought is about the nurse's role as a bridge.

Patients exist in a world where are bombarded with natural is better marketing.

Medicine exists in a world of rigid trials and chemistry.

The nurse is the only person who stands in the middle.

You have to respect the patient's choices and culture, but you also have to protect them from the chemistry they don't understand.

Natural does not mean safe.

If you can teach your patients that one phrase, you might save a life.

That is a powerful place to end.

We've unpacked the regulatory gray areas, the forms of herbs, the specific players from ginseng to St.

John's wort, and the critical safety checks for surgery and drug interactions.

It's a lot to digest, but it's practical knowledge you will use every single day in practice.

Thanks for joining this deep dive.

This has been the Last Minute Lecture Team.

Good luck with your studies.

Good luck, everyone.

Stay safe out there.
