A woman in a cardiac support group posted this week about drinking peppermint and licorice tea to help with recovery. Two cups sent her blood pressure through the roof. It took two days to come back down.

She'd also been told to avoid grapefruit, turmeric, and fish oil before leaving hospital. Nobody mentioned licorice.

Licorice root contains a compound called glycyrrhizin. It blocks an enzyme in your kidneys that normally keeps cortisol from activating your mineralocorticoid receptors. When that enzyme is blocked, cortisol behaves like aldosterone: your body retains sodium, loses potassium, and your blood pressure rises.

A 2024 randomised controlled trial published in the American Journal of Clinical Nutrition found that 100 mg of glycyrrhizic acid per day, for just two weeks, raised systolic blood pressure by more than 3 mmHg and suppressed renin and aldosterone in healthy young adults. That's the equivalent of a couple of cups of licorice-containing tea. For someone already on blood pressure medication or antiplatelet therapy, the margin for harm is much smaller.

The potassium loss matters separately. Low potassium prolongs the QT interval, which can trigger serious cardiac arrhythmias. If you're on digoxin, even modest potassium depletion can push you into toxicity territory.

Licorice is in more products than people realise: throat and digestive teas, herbal lollies, cough syrups, and some "adrenal support" supplements.

The thread also raised vitamin B6.

The TGA finalised a decision in November 2025 to make high-dose B6 products either pharmacist-only or prescription-only from June 2027. The reason: a sharp rise in reports of peripheral neuropathy, with tingling and numbness in the hands and feet, at doses well below what was once considered the danger zone. Some cases were documented at under 50 mg per day.

The problem isn't usually one large supplement. It's stacking: a multivitamin, a B-complex, a magnesium product, and an energy drink, each with a modest dose of pyridoxine, adding up to something significant over months.

This is exactly what naturopaths are for.

Not to scare you away from herbs and supplements. Quite the opposite. Many supplements are genuinely useful, and some, like fish oil at standard doses, have been shown to be safer alongside anticoagulants than the old warnings suggested.

But whether a supplement is right for you depends on what you're taking, what your body is doing, and what your specific history looks like. That context lives with a practitioner, not in a Facebook thread.

If your sleep has changed since perimenopause, here's the physiological reason why.

Oestrogen plays a moderating role in the HPA axis, the feedback loop that governs your cortisol and stress response. When oestrogen is stable, the HPA axis handles everyday stressors without much difficulty. As it declines, that buffer reduces. Cortisol, particularly in the evening and overnight, tends to rise as a result.

That elevated overnight cortisol is the driver behind the wired-but-tired pattern so many perimenopausal and post-menopausal women describe. Exhausted, but can't fall asleep. Or asleep by 10pm, then wide awake at 3am with a mind that won't chill out.

That's not a sleep discipline problem. That's a hormonal pattern.

Progesterone compounds the picture. It has a direct calming effect on the nervous system via GABA receptors, the same pathway involved in natural sleep regulation. Progesterone is also one of the first hormones to decline in the menopausal transition, which is why sleep patterns often shift earlier than people expect, sometimes years before their last period.

Sleep hygiene advice is reasonable as a starting point. But it addresses behaviour, not physiology. For most post-menopausal women, sleep improves meaningfully when the hormonal and metabolic drivers are addressed directly.

Today marks two years of Simply Naturopathics. 🥳

When I started, I wasn't sure anyone in a small regional town would want what I was offering. Turns out, plenty of you did. And most of you had been waiting a long time for someone to actually listen.

That hasn't changed.

Year three. I'm ready if you are.

If you've noticed your energy crashing in the afternoon, or your weight shifting despite no real change in what you eat, your blood sugar regulation is worth understanding.

In perimenopause, oestrogen decline directly affects how well your cells respond to insulin. The result is a blood sugar pattern that's harder to manage - sharper spikes after meals, more pronounced drops, and the fatigue, brain fog, and cravings that follow.

One thing that makes a meaningful difference: movement breaks.

A 2024 study found that getting up every 45 minutes and moving for just three minutes reduced post-meal blood sugar levels by up to 21%. (PMID: 38629807)

Squats were particularly effective because they recruit the large muscles of the legs and glutes - the primary sites of glucose clearance in the body.

Three minutes. Every 45 minutes.

Set a timer and that's the entire system!

I've written a full post covering why blood sugar becomes harder to regulate in perimenopause, what's actually happening after you eat, and how to make movement breaks work in a real day.

Low ferritin that won't shift despite supplementation is a pattern I see often in clinic - and there's almost always a reason.

The problem is rarely a simple lack of iron. More often it comes down to one of three things:

1️⃣ How well the gut is absorbing iron in the first place;
2️⃣ Whether stomach acid is adequate to activate it, or
3️⃣ Whether low-grade inflammation is triggering a hormone called hepcidin that physically blocks iron from entering the bloodstream.

That last one surprises most people. Your body sequesters iron deliberately when it detects an inflammatory load - even the kind that doesn't feel like obvious illness. More iron supplementation doesn't solve it. The environment needs to change first.

Your thyroid and your menopause are connected - and most women aren't told that.

When oestrogen drops, it affects thyroxine-binding globulin - the protein that carries thyroid hormones through your blood. The result is that your thyroid has to work differently, and the symptoms - fatigue, weight resistance, brain fog - can look almost identical to menopause.

Your TSH might sit in the normal range. You might still not feel right. That gap is real, it's well-documented, and it's worth looking at properly.

A thorough assessment looks at your symptoms, your blood results in context, and what your body is actually doing - not just what falls outside the flagged range.

I'm a naturopath and former registered nurse. I'm also someone who has had a heart attack caused by SCAD, spontaneous coronary artery dissection, a condition many people have never heard of.

My calcium score was zero, and my arteries weren't blocked in the usual way, so the standard picture of cardiovascular risk didn't apply to me. I hadn't even reached 50 yet!

SCAD is a recognised cause of heart attack that disproportionately affects women, and it is not the usual cholesterol-driven, atherosclerotic pattern of heart disease.

That experience shapes the way I think about women's cardiovascular health, particularly during and after menopause.

As oestrogen levels decline, the cardiovascular system changes too, including blood vessel function and lipid patterns, which means risk can look different from the standard messaging we often hear.

I'm not sharing this to alarm anyone. I'm sharing it because Heart Week often centres a picture of heart disease that leaves many women unrecognised.

If cardiovascular health is something you'd like to understand better in the context of your own
hormonal picture, I'm currently taking bookings for Initial Clinical Assessments, in-person in Rutherglen and Yarrawonga, or via telehealth anywhere in Australia. Book through the link below.

"Everything looks normal."
It's one of the most frustrating things to hear when you know something has shifted in your body. I've heard it myself.

Standard reference ranges are designed to detect disease — not to identify where your body is functioning below its best.

Ferritin at 28 is within range.
It's also low enough to impair energy and thyroid hormone conversion — without triggering a single flag on a standard report.

TSH at 3.8 is within range.
It sits toward the end that correlates with fatigue, weight changes, and low mood in many post-menopausal women.

Functional blood chemistry analysis reads the same results differently — against optimal ranges for your age and symptoms, and across markers rather than in isolation.

It's not about finding something your GP missed.
It's about asking a different clinical question of the same data.

Have you ever been told your results are normal but still felt something wasn't right?

I'd love to hear your experience in the comments.

Waking at 3am and can't get back to sleep?

It's one of the most frequent things I hear from women in their 50s, 60s, and 70s — and one of the most consistently misunderstood.

It isn't traditional insomnia. And it usually isn't stress, even when it feels that way.

There are three specific physiological reasons why 3am is such a consistent pattern in post-menopause — and none of them are fixed by a magnesium supplement and an earlier bedtime.

I've written a full explanation on the blog, including what's actually happening hormonally between 2am and 4am, and three evidence-informed places to start.

Simply Naturopathics supports clients in Corowa, Rutherglen, Yarrawonga, Mulwala, Howlong, Chiltern, Wangaratta, Albury and Wodonga.If you’re outside the local area, I also offer telehealth consultations across Australia, so you can access care from wherever you are.

You don't have to be going through something dramatic
for cortisol to be affecting your weight, sleep, and energy.

After menopause, oestrogen no longer buffers cortisol's effects on the body.
The same daily load (busy schedule, disrupted sleep, high exercise output) lands differently at 55 than it did at 40.
Not because you're handling it worse.
Because the hormonal context has changed.

Elevated cortisol drives fat storage around the abdomen.
It raises blood sugar.
It disrupts sleep.
It slows the conversion of thyroid hormone into its active form.

And the sources aren't always obvious.

Under-eating raises cortisol.
Over-exercising without adequate recovery raises cortisol.
Poor sleep both causes and results from elevated cortisol.

This is one of the first things I look at in clinic —
because until cortisol load is addressed,
most other interventions have limited effect.

Does this resonate with where you're at?
