THE CLINIC
Heal Naturally started with just a couple of local patients, but with exactly the same goal as today: to help people overcome chronic gut health problems.
I'm now lucky enough to practise from a beautiful dedicated clinic space on my smallholding in North Devon.
Outside of clinic hours, I'm usually outside doing something muddy! - Rewilding, growing food, and managing the woodland.
MY HEALTH JOURNEY
If you’re reading this, chances are you're stuck in the cycle of bloating, fatigue, and frustration that comes with gut problems.
Trust me, I know how draining that is, because I’ve been there too.
In my twenties, I was training to be a pharmacist - I was exhausted from the unrelenting pressure, had a terrible diet and I ended up taking multiple courses of antibiotics for tonsillitis that just constantly came back.

In the background my body and microbiome were falling apart. It got the point where every day was an extreme challenge, I was exhausted and in constant pain from my gut problems. I pushed through every day by using coffee, pain killers and antispasmodic drugs.
It was so frustrating to be told repeatedly by healthcare professionals that the symptoms dominating my life were: "just IBS” or even worse that they were "psychological".
I tried everything I could to fix things - a million supplements, endless advice from books and reddit 'experts', every 'superfood' I could think of.
Nothing worked.
Each new attempt brought hope but it would eventually end in the same cycle of bloating, exhaustion, and anxiety. I felt totally dismissed by the system, stuck in a body that wasn’t working, and increasingly hopeless that anything would change.
Luckily, discovering natural medicine changed everything. Though the process of recovery was challenging and full of hurdles, through herbal medicine, nutrition, and a deeper respect for the body’s own signals, I finally began to see lasting improvement. My symptoms eased, my energy returned, and I was able to rebuild my life. That experience not only transformed my health, it completely reshaped my the way I think about medicine.
Today, I have the privilege of helping other people who feel stuck, hopeless, or dismissed by conventional medicine to finally get answers that make sense and treatments that actually work to help correct the root causes of their gut symptoms.

So if you have tried everything, been told it is just IBS, and still don't have answers, you are in the right place.
I know what it feels like to be stuck, and I know you can feel well again.
I told myself I was way too young to be this ill.
