The SYLVANA cold-air nebulizing diffuser in ribbed glass and brass, releasing a fine mist on wet stone beside a 10ml amber oil bottle, in a misty old-growth forest.

SYLVANA

Nature's pharmacy,
cold-diffused.

We put the healing air of the world's ancient forests into your home.

Trees release healing compounds called phytoncides. We bottle them and diffuse them into your home — the documented benefits of a forest walk, every day, without leaving the house.

What We Do

We bring the forest indoors.

Not the scent of a forest. The actual compounds that make forest air measurably good for you.

01

We study the air

Researchers in Japan measured precisely which airborne compounds give ancient forests their effect on the body. They're called phytoncides — volatile compounds trees release to defend themselves, which our bodies respond to when we breathe them.

Decades of measurement. A specific list of molecules.

02

We formulate the compounds

Each SYLVANA formulation is built to match a documented terpene profile — the same molecules found in that forest air. Pure oil, 10ml, no carrier, no filler, no synthetic fragrance.

Every compound named on the bottle, and cited on this site.

03

We put them in your air

A cold-air nebulizing diffuser turns the pure oil into a dry micro-mist without water or heat — because heat degrades the very compounds that do the work.

What leaves the bottle is what you breathe.

04

It isn't the walk. It's the air.

The obvious objection is that forests make people healthier because people exercise in them. Researchers tested exactly that — pooling 20 trials, comparing people walking through forests against people who simply sat and looked at one.

Blood pressure fell in both groups, by almost the same amount: −3.48 mmHg walking, −2.99 mmHg sitting still. The authors concluded the effect is not caused by physical activity at all.

Which means the benefit is in the air itself — and air is something we can bottle.

−3.15 mmHg Systolic blood pressure Meta-analysis · 732 people, 20 trials

Heart rate fell by an average of 3.84 bpm across 13 trials — and among people who already had elevated blood pressure, systolic pressure dropped 6.33 mmHg, nearly double the overall effect. For scale, Japan's national health programme estimates that a 4 mmHg drop in average systolic pressure measurably lowers stroke mortality.

These are findings from published research measuring people in forest environments and breathing diffused tree compounds — the science SYLVANA is built on. Every study is listed with a link on The Science.

The Difference

Not zero VOC.
Beneficial VOC.

Most clean brands market around removing harm. We market around adding measurable biological benefit.

Phytoncides

The same volatile compounds emitted by Akasawa Forest's ancient hinoki cypress trees, now in every formulation we make.

Peer-Reviewed

Every terpene in every formulation is backed by published clinical research. We don't guess at what makes you feel good.

Documented Effects

Cortisol reduction. Dopamine activation. Endorphin receptor binding. Real outcomes, real science.

The Collection

Five states of mind.
One forest.

Each formulation is built around a distinct, documented terpene profile — engineered for a specific biological outcome. 10ml pure oil. No fillers. No synthetics.

The highest antioxidant score ever recorded in nature.

Dragon's blood — harvested from the Croton lechleri tree deep in the Amazon rainforest — carries more antioxidant power than any substance known to science. 9x stronger than cloves. 550x more potent than vitamin E. It is our hero ingredient, and it is in every body oil we make.

Origin

Inspired by Akasawa Forest, Japan

Deep in the mountains of Nagano, Japan, the Akasawa Natural Recreation Forest has been healing people for centuries. Home to 300-year-old hinoki cypress trees, it was designated Japan's first official Forest Therapy Base. The air there — dense with phytoncides — has been proven to lower cortisol, reduce blood pressure, and increase natural killer cell activity by over 50%. SYLVANA was born from one question: what if you could bring that forest home?

Delivery

The Delivery Difference

The molecule only works if it survives the trip into your air.

Why Nebulizing Wins

A nebulizing diffuser uses pressurized cold air to atomize pure oil into a dry micro-mist — no water, no heat, no carrier. Terpenes are volatile and heat-sensitive: burn them or boil them and you degrade the exact compounds you were trying to breathe. Cold atomization delivers the full profile intact, at therapeutic concentration.

Why Ours Is Undiluted

Most diffuser oils are a few drops of active material suspended in a carrier. SYLVANA formulations are pure terpene oil — nothing added to stretch the bottle, nothing synthetic, nothing we can't name and cite. Every compound in the bottle is there because published research says it does something.
