This is

  • A personalised herbal AI that knows your medications
  • A real-time herb-drug interaction checker
  • UK-specific — Boots, Holland & Barrett, British Pharmacopoeia
  • Built on 16 years of practising herbalist knowledge
  • An answer to your specific question — not a generic herb summary

This is not

  • A course with modules, homework, or a certificate
  • A herb database or reference library to browse
  • A generic AI that searches the internet
  • A replacement for your GP
  • One-size-fits-all advice written for a notional average person
In practice

A real question. A real answer. From a real profile.

This is an actual exchange from The Green Tutor. Not a demo written to look good. The profile was set up at the start — the answer comes from it.

Profile: dry constitution  ·  prefers teas  ·  no current medications
You
I have chamomile, yarrow, and calendula at home and my head started hurting. Can they help?
GT

Can you tell me more about your headache — where it is, what it feels like (throbbing, dull, sharp), and whether anything else is going on?

You
It's throbbing.
GT

Any other symptoms — fever, neck stiffness, sensitivity to light or sound, nausea, changes in vision?

You
Nothing else.
GT
⚠ Checking against your constitution

A throbbing headache without fever or neck stiffness often signals congestion or circulatory pressure — sometimes with a heat element. Given your dry constitution, we want to address that without adding to dryness.

All three herbs you have are relevant here. Chamomile is the relaxant — it'll ease any nervous tension or irritation underlying the throb. Yarrow is the more active choice: it moves stagnant blood, opens peripheral circulation, and can draw congestion away from the head. Calendula adds anti-inflammatory and lymphatic support if there's any congestion in the head and neck contributing.

Try 1 part chamomile, 1 part yarrow, and half a part calendula. One tablespoon of the mix per cup, steep covered for 10–15 minutes, strain and sip warm. The cover matters — yarrow's volatile oils disperse in steam.

If the headache is severe, unusual for you, or doesn't ease within an hour or two, that's when you involve a GP rather than a herb.

It asked two questions before recommending anything. That's what a herbalist does. Every other resource would have given you a list of what chamomile "does." This one found out what you needed first.

Is this for you

This is built for a specific kind of person.

This works if you

  • Take herbs or supplements alongside prescription medication
  • Want a straight answer to your specific question — not another reference to look up
  • Feel overwhelmed by conflicting advice from books, apps, and Google
  • Are learning for yourself, your family, or both
  • Want something built for the UK — not adapted from the US

Probably not if you

  • Want a structured course with modules and a certificate
  • Prefer to browse a herb library at your own pace
  • Would rather work with a human herbalist directly (if you can, that's always the better option)
How it works

Tell it about you once. It remembers everything after that.

1

Tell it about you

Medications, sensitivities, health goals, who you're learning for. Takes 3 minutes. Does all the heavy lifting for every answer that follows.

2

Ask your question

In plain English. The one you Googled at 11pm. The one your GP dismissed. Start there.

3

Get an answer shaped to you

Not what this herb does in general. What's appropriate for you — with your medication list already checked before the answer reaches you.

4

Keep coming back

It remembers. Builds on what it knows. Gets more useful the longer you use it.

From members

In their own words. About their actual situations.

★★★★★
"I had this specific question about St John's Wort and whether it would be okay with my blood pressure tablets and every time I searched I just got the same vague 'consult a healthcare professional' answer. Within about half an hour I had an actual answer. Not a hedged non-answer. An answer. I've been on the blood pressure medication for four years and nobody — not the pharmacist, not my GP — had ever gone through the herb side of things with me."

"It flagged an interaction with my levothyroxine straight away. I'd been taking ashwagandha for months — the woman in Holland & Barrett suggested it. My GP doesn't even know I take supplements because every time I've brought it up she just says to check the packet. The packet said nothing. This did."

"I did an online diploma. £380, four months, learned almost nothing useful. The Green Tutor is different because it goes in the direction I'm already going. I don't have to work out how to apply the information to me — it already knows who I am. That sounds like a small thing but it's the entire problem with every other resource I've tried."

"My nan knew all of this. She had something for everything. I kept meaning to ask her to write it down properly and I left it too late. It's the first time I've found something where the learning feels like it's building toward something rather than just collecting facts. It feels more like remembering than studying, if that makes sense."

Why you're still stuck

Every resource you've tried answered the wrong question.

Your question was never "what does this herb do?" It was "is this herb safe for me — right now, with my blood pressure medication, my history?" No book, app, or generic AI can answer that. Not because the information doesn't exist. Because they were built for everyone, which means they were built for no one in particular.

📚 The Books

Indexed by Latin name. Written for practitioners. One member spent £87 on three books and used none of them. They're still on the shelf.

📱 The Herb Apps & Sites

A beautiful database of 400 herbs, none of which know anything about you. Search "valerian and ramipril" and get a generic warning with no context, no follow-up, no memory of your situation.

🔍 Google & the Forums

Two contradicting studies, both from 2009. A Mumsnet thread that ends with "but definitely check with your GP." You check with your GP. They suggest paracetamol.

🏥 Your GP

76% of people who use herbal remedies don't mention it to their GP — not because they're hiding something, but because they've tried once and learned the conversation isn't worth having.

What's actually going on

The information was never the problem.

Every resource you've tried answered the same question: "What does this herb do?"

That wasn't your question.

Your question was: "Is this herb safe for me — right now, with my medication, my symptoms, my history?"

No book, app, or generic AI was built to answer that. They were built for everyone. That's structurally why they couldn't work for you — and why this has nothing to do with how hard you tried.

"I do not feel I can gather enough reliable information about specific conditions, treatments, and dosages to actually use it safely."
— UK herbal forum. One of thousands of identical posts.
77%
of herbal users in the UK don't understand the risks of what they're taking. More information hasn't fixed that number. Different information will.
What makes it different

Three things every herbal resource skips. We built the whole product around them.

01
🧠

Contextual Memory

You tell it your medications, health goals, sensitivities. It stores your profile and filters every answer through it — every time, without you having to repeat yourself.

Ask about ashwagandha today. It already knows you're on warfarin. It gives you the answer you actually needed, not the one on the packet.

Every other resource resets to zero when you open it
02
📍

Adaptive Learning

No fixed syllabus. No predetermined path. It builds outward from your real questions — starting where you actually are, not where a course designer assumed you'd be.

You don't need to learn 500 herbs. You need to understand the 8 most relevant to your current situation. It starts there.

Every reference tool resets to zero each time you open it
03
🛡

Real-Time Safety Layer

Built and maintained by Roland from the British Herbal Pharmacopoeia, 16 years of clinical notes, and peer-reviewed herb-drug interaction research. Checks dosage safety against your profile — not a generic adult template.

This is the layer that makes the fear go away — not by pretending risks don't exist, but by navigating them for your specific situation.

Generic AI has no safety architecture. It has confidence. That's worse.
Your first 6 months

What this actually looks like, in real life.

Not a curriculum. This is what members tend to find themselves doing — because the learning follows their questions, not the other way around.

Week 1
Start with whatever's already in your cupboard
  • Ask about the supplements you've been taking without quite knowing if they're right for you
  • Run your first safety check against your own medication list
  • Get a straight answer to the question you've been putting off
  • No syllabus. No pressure. No homework.
First Month
Know a handful of herbs properly — not a hundred herbs vaguely
  • Really understand 5–7 herbs: how they work, for whom, and when not to use them
  • Grasp the safety fundamentals most books bury in appendices
  • Make your first simple preparations and actually trust them
  • Start seeing the patterns that connect different herbs
Three Months
Handle everyday situations without second-guessing yourself
  • Know what to reach for when someone in your family needs support
  • Understand when a herb isn't working — and why — instead of just giving up
  • Begin making your own decisions on preparation and dose
  • Feel the difference between information and understanding
Six Months
The knowledge your grandmother had — rebuilt, and yours
  • Navigate most everyday situations without needing to look anything up
  • Pass the knowledge on to your family in a way that actually sticks
  • Build a home herb kit specific to your household
  • Know clearly when herbal knowledge ends and when a GP is the right call

Not about becoming an expert. About becoming someone who trusts what she's doing — because she understands it, not just because a packet told her to.

When a herb "doesn't work"

You tried valerian for sleep. It didn't work. That's not evidence that herbs don't work. It's evidence that nobody asked you the right questions first.

You bought it from Holland & Barrett. You took it at bedtime, as directed. Maybe you even tried it for a week. You still couldn't sleep.

And so you arrived at the conclusion so many women arrive at: either herbs don't work, or they don't work for you.

Valerian is not a general sleep herb. It's a specific herb for a specific kind of sleeplessness. A herbalist would have asked you six questions before recommending it. Not one of them is on the packet.
Reason 01
Valerian may be the wrong herb for your type of insomnia

It works for tension-based sleeplessness. If your problem is a racing mind, lemon balm or passionflower are more appropriate. If you're wired and restless, hops or skullcap address that pattern more directly. Generic herb advice skips that question entirely.

Reason 02
The preparation may be wrong for your metabolism

Standard tea steeped for 5 minutes may be too weak. For some metabolic types, tinctures are the only preparation that produces a measurable effect. The "one cup at bedtime" instruction is a liability-minimising average.

Reason 03
You may have a plant family sensitivity nobody flagged

If you have hay fever or pollen allergies, herbs from the Asteraceae family can trigger a histamine response that actively disrupts sleep rather than promoting it. Not rare. Just not mentioned on any packet.

Reason 04
Timing and quality matter more than most people realise

Taking valerian within 90 minutes of caffeine means the stimulant effect wins. Using an 18-month-old product from the back of the shelf means you may have lost 50–70% of the active constituents.

Reason 05
The dose was never calibrated to you

A 52kg woman and an 88kg man are advised the same dose on the same packet. Fast metabolisers need more or more frequent doses. Sensitive types need half. Neither gets useful guidance from a general label.

Reason 06
You may have an interaction nobody told you about

Valerian interacts with sedatives, antihistamines, antidepressants, and some blood pressure medications. The packet says "consult your GP." Your GP hasn't been trained in herb-drug interactions. The Green Tutor's safety layer has — and it checks before suggesting anything.

🌿

None of those six questions are hard. A herbalist asks them before recommending anything. A packet can't ask them at all. That's the gap. The Green Tutor asks them first — every time, for every herb, filtered through what it already knows about you.

Before anything else

The safety layer wasn't a feature. It was the reason we built this at all.

Roland has seen too many women use herbs that interacted with their medication because no one told them. Not because the information didn't exist — but because it wasn't connected to their specific situation.

The safety layer was built before anything else. Before the learning pathways, the herb library, any of it. Because without it, The Green Tutor would just be another way to give you information you couldn't safely act on.

Every herb-drug interaction is verified by Roland against clinical literature. The knowledge base doesn't access the internet. Updated quarterly. Checked against your profile — not a generic adult template. You.

Questions

If you're sceptical, good. Here's what you should ask.

Fair question. Generic AI generates answers by pattern-matching across the internet — including the bad information. The Green Tutor's knowledge base was built by Roland over 16 years of clinical practice, grounded in a BSc in Biology and cross-referenced against the British Herbal Pharmacopoeia and peer-reviewed herb-drug interaction research. It does not access the internet. The AI delivers that knowledge. It doesn't create it. Every herb-drug interaction in the safety layer has been verified against clinical literature, not inferred by a language model.
Herb apps are databases. They store information about herbs and let you search it. The Green Tutor isn't a database — it has a profile of you. It knows your medication list, your goals, your sensitivities. Every answer is filtered through what it already knows about your situation. That's not a better reference tool. It's a structurally different kind of thing — built around your specific question, not around organising information for a generic user.
It retains everything you share. Your medications, goals, sensitivities — stored in your profile and applied to every interaction. Ask about a herb today, come back next month: it already knows your context. (The memory refreshes every 30 days, so you'll occasionally be asked to confirm your profile is still accurate. That's a safety feature, not a flaw.)
Built for the UK. Holland & Barrett. Boots. NHS context. British plant names. British Herbal Pharmacopoeia as the reference standard. Perimenopause, not "menopause transition." PMT, not PMS. Metric measurements. The herb names match the packets you're actually buying. You'll notice the difference within your first interaction.
No — and we'll tell you clearly when something should go to your doctor. The Green Tutor exists in the enormous space between a GP appointment and endless Googling: which herbs are safe with your medication, how to use the supplements in your cupboard, what's appropriate for your symptoms. For anything that needs a diagnosis or prescription, your GP is the right call. We're not competing with that.
If you can send a text message, you can use The Green Tutor. It's a conversation, not a dashboard. You type a question in plain English — no Latin names, no correct format required. No settings to configure. No onboarding video. The first useful interaction takes about 5 minutes from signup, including the 3 minutes to set up your profile.
Simple. If in your first 30 days you don't find The Green Tutor more genuinely useful than any herbal resource you've previously tried, email us and we'll refund in full — no questions asked. Every plan includes this guarantee. We make that offer because we're confident. You should be sceptical enough to hold us to it.
Your subscription renews automatically at the end of each billing period. Cancel any time from your account profile and you won't be charged again. No phone call, no retention team. If you cancel mid-period, you keep access until the end of the period you've already paid for.

Somewhere in your family, this knowledge existed.
It just didn't get passed down in time.

Most of us have a grandmother, or a great-aunt, or a neighbour who just knew. That knowledge wasn't magic. It was accumulated, personalised, and trusted. The Green Tutor is the first tool built to give it back — properly, safely, in a way that's actually yours.
