If you wake up bloated. If you can't stop craving sugar. If you grind your teeth at night. If you itch in bed and don't know why, this wasn't written by accident.

These aren't four unrelated problems. They're four warning signs of one hidden cause that modern medicine in the UK isn't looking for.

I've been treating it for 22 years. I've seen every test result imaginable come back 'normal' while the patient sat in front of me clearly not normal.

What Western medicine misses: most of what makes you feel terrible is caused by what's living inside you.

The 4 Signs I Check For

Do any of these sound familiar?

  • Sugar cravings you can't control Especially dairy, ice cream, yoghurt, cheese. Parasites feed on milk and sugar. They don't just crave it. They make you crave it.
  • Grinding your teeth at night That jaw tension, the clenching while asleep. It isn't stress. It's your nervous system reacting to what's inside you.
  • Itching at night, especially down there Parasites are most active when the body sleeps. This is when they move.
  • Bloating after every meal They take your nutrients first. What's left ferments. You end up swollen, gassy, exhausted, and told it's 'normal'.

Three or more? Keep reading. This wasn't written for people who only have one.

What's Actually Happening Inside You


An internal parasite or bacterial overgrowth is feeding on what you eat, poisoning what's left, and making your body work twice as hard to keep up.

These organisms are common. Far more common than anyone talks about. Testing for them in the UK essentially doesn't happen unless you've returned from abroad with a specific illness.

They cause the exact symptoms you're living with:

Sugar cravings: they want your sugar
Teeth grinding: they disturb your nervous system at night
Night itching: they're most active while you sleep
Bloating: they ferment your meals inside you

The NHS doesn't test for this. Private gastroenterology won't test for this. You're told it's 'probably IBS' and handed a prescription for symptoms, not a solution. Chronic illness is recurring revenue. That isn't cynicism. That's the business model.

What 2,000 Years of Medicine Already Knew


In our tradition we've treated this for two thousand years using two specific plants. Not one. Both together. Each one does what the other can't.

Western science is finally catching up. The primary compound in the first plant is now called carvacrol in their research. At 85% concentration, it destroys what's feeding on you. Below that, it just annoys them.

The second plant is what makes the first one safe. It escorts the dead organisms and their toxins out of your body before they can poison you on the way out.

Step 1
KILL - Wild Oregano Oil (85% Carvacrol)
KILL

The carvacrol in wild oregano dissolves the biofilm, the slime shield parasites hide behind, then kills them on contact.

Antibiotics can't penetrate the biofilm. Oregano oil below 50% concentration can't either. 85% is the threshold. Anything less is theatre.

Step 2
FLUSH - Cold-Pressed Black Seed Oil
FLUSH

Black seed oil binds to the dead parasites and their toxic waste, escorting everything out of your body safely.

Skip this step and you rot what you killed inside yourself, the 'die-off' feeling most people describe. With black seed oil in the protocol, most patients don't feel it at all.

One kills. One clears. Used alone, neither does the job. Used together, this is how we've been treating this for two thousand years.

"In 22 years I have watched this protocol do what three rounds of Western antibiotics could not. In less time. Without damaging the patient. This is not new medicine. This is what we have always done."

The Brand I Give My Patients


I've been asked hundreds of times which brand of oregano and black seed oil I recommend. I never endorsed one publicly until this year.

Most oregano oil in the UK tests at 30-50% carvacrol. At that concentration it does not kill parasites, it just irritates them into hiding deeper.

The only UK brand I've found that meets the 85% threshold, uses third-party verification, and combines both oils in the correct dose is Herbies Oregano+.

30 Days, Same Protocol, No Diet Changes


Below is what happens when someone with three or four of the warning signs follows the protocol, 2 softgels a day with their main meal, for 30 days. No changes to diet. No exercise programme. Just the oils.

Before and after 30 days on the protocol

Week 1. Bloating visibly reduces. Teeth-grinding stops, usually the partner notices first.

Week 2. Sugar cravings disappear. Most patients say this is the first time in years they're eating because they're hungry, not because something inside them is demanding it.

Week 4. Weight drops without dieting. Sleep through the night. Energy back.

What patients say at follow-up: "I didn't realise how sick I'd been until I wasn't anymore."

What Patients Say After the Protocol

Sign #1 was me. I thought I just had a sweet tooth. Three weeks on Herbies and I walked past the biscuit aisle without thinking about it. I didn't know that was possible.

My wife heard me grinding my teeth for six years. Three weeks on this and she says the bedroom is silent. I hadn't realised what I was doing to my jaw every night.

Bloated every single evening for as long as I can remember. I'm a week in and my stomach is flat again by 9pm. I nearly cried taking my jeans off without having to unbutton them first.

I spent £1,200 on private gastroenterology. Nothing worked. Two softgels a day with dinner and I feel like myself again. Why did no doctor mention this?

One note before you close this page.

I've been told Herbies is including a limited number of free bottles with orders this month. I can't confirm how long. If this is something you were planning to try, sooner makes more sense than later.

If It Doesn't Work, You Don't Pay.


I wouldn't be recommending this otherwise. The only risk is continuing to do what hasn't worked.

If you don't feel a clear difference within 60 days, Herbies refunds you. No questions, no forms, no phone calls.

Frequently Asked Questions

How quickly will I see results?

Most people notice changes in bloating and sleep within the first 7 days. Sugar cravings drop in week two. Full results usually land between week three and week four. Some people take longer. The body has been compensating for years, give it the full 60 days.

Is it safe to take with medication?

Wild oregano oil and black seed oil are food supplements, not drugs, but if you're on prescription medication, especially blood thinners, diabetes medication or blood pressure medication, speak to your GP or pharmacist before adding anything new to your routine.

Will I feel worse before I feel better?

This is called a 'die-off' reaction: temporary fatigue or loose stools as the body clears what the oregano has killed. It's a good sign, not a bad one. The black seed oil in Herbies specifically reduces this effect. Most customers don't notice it at all.

Do I need to change my diet?

No. You can cut sugar and refined carbs to help the protocol work faster, but it isn't required. Many customers see full results while eating exactly the same way they always have.

How long should I take it for?

A full cycle is 30-60 days. Most patients in my clinic do 60 days for a deep reset, then optionally 30 days twice a year for maintenance.

Is it safe if I'm pregnant or breastfeeding?

No. Wild oregano oil at therapeutic concentration is not recommended during pregnancy or while breastfeeding. Wait until after, or speak to a qualified practitioner about alternatives.

What if it doesn't work for me?

You return the bottle, even empty, within 60 days and Herbies refunds you in full. No forms, no phone calls. That's why I recommend it; I wouldn't otherwise.

P.S. If you recognise three or four of the warning signs in yourself, that's not coincidence. Most people live with them for years because no one tells them there's a name for it. There is. And there's something that works. Your body knows how to fight back when you give it what it needs.
