Some remedies arrive and fade. Valerian stayed.
It has been in continuous use as a sleep and calming herb for over two thousand years, across cultures that had nothing in common except this one plant and the human need for rest. That kind of longevity isn't sentiment or folklore. It's a track record.
Hippocrates wrote it down
The earliest documented use of valerian as a medicinal herb dates to ancient Greece. Hippocrates — the physician whose name is still attached to the oath every doctor takes — described its properties around 400 BC. Galen, the Roman physician whose influence shaped European medicine for over a millennium, prescribed it regularly for patients suffering from sleeplessness and nervous agitation.
The name itself is telling. Valerian comes from the Latin valere — to be strong, to be well. The same root gives us valiant, valid, and value. The Romans were precise people. They chose that name deliberately.
The monks, the abbeys, and the physic gardens
Through the medieval period, valerian became a staple of European herbal medicine. Benedictine monasteries across Germany, France, and England grew it in their physic gardens alongside lavender, chamomile, and rosemary. It was cultivated not as decoration but as medicine — a working plant with a specific job.
Hildegard of Bingen, the 12th century German abbess, mystic, and extraordinary pioneer of natural medicine, wrote about valerian's calming properties in her medical texts. She was centuries ahead of the pharmacological research that would eventually explain why she was right.
In medieval England, valerian root was expensive, sought after, and used as a spice, a perfume, and a medicine simultaneously. It was ground into food, steeped in ale, tucked into bedding. People who couldn't afford physicians found it in hedgerows and knew exactly what to do with it.
The First World War
Here is the detail that stops people.
During the First World War, valerian was administered to soldiers suffering from shell shock — what we would now recognise as acute post-traumatic stress disorder. The sustained terror of industrial warfare, the inability to sleep, the nervous system locked permanently in a state of alarm — valerian was one of the few tools available to military physicians trying to help men whose bodies had forgotten how to be still.
It didn't undo what the trenches had done. Nothing could. But it was prescribed because it worked well enough to matter, in circumstances where almost nothing else did. That is not a small thing.
What's actually happening
Valerian root contains a group of active compounds — valerenic acid being the most studied — that appear to inhibit the breakdown of GABA in the brain. GABA is the neurotransmitter responsible for reducing neuronal excitability. The brain's natural brake pedal.
When GABA breaks down too quickly, the brain stays alert. Restless. Busy. Valerian slows that breakdown. The brake pedal finds purchase. Sleep becomes possible.
This is also, broadly, how benzodiazepines work — the class of prescription drugs that includes diazepam and temazepam. The mechanism has similarities. The intensity and risk profile are entirely different. Valerian works gently, without the dependency, without the morning fog, without the prescription.
Two thousand years of use before anyone understood the mechanism. The mechanism, when finally understood, confirmed exactly what the Greeks had observed.
The smell
We should be honest about this because everyone who has ever opened a bottle of valerian extract has had the same reaction.
It smells terrible. Earthy, pungent, aggressively herbal in a way that is difficult to describe politely. Dioscorides mentioned it. Medieval herbalists mentioned it. Every modern review of valerian supplements mentions it.
The smell comes from isovaleric acid, produced as the root dries and ages. It is not subtle.
This is precisely why valerian has traditionally been taken in capsules, or combined with something powerful enough to hold its own against it.
Bara Brith Syrup — warm with muscovado sugar, cinnamon, cloves, orange peel, and blackstrap molasses — holds its own against it with considerable ease. You would not know valerian was there. That is entirely the point.
Valerian in Noddfa Nos
We use an alcohol-free 1:1 Valerian Root Extract — meaning the active compounds are preserved without the burn of an alcohol tincture. Three millilitres per bottle, the largest single herbal component in the formula.
It earns that place. After two thousand years of consistent use across almost every culture that encountered it, valerian has the longest and most consistent track record of any herb in Noddfa Nos.
Hippocrates was right. The Roman physicians were right. The medieval monks were right. The First World War doctors were right.
Some things just work.
Noddfa Nos is available now at noddfa.rest. £19.95 for 30ml. Two pumps in warm milk at bedtime.
