Plant Catalyst
Before it happens,
Purify the air.
Purify your life.
Prevention starts with your living environment.
Natural Ingredients
HPcure is made from 100% natural ingredients.
About 60% of the substances we absorb come from indoor air. A space full of chemicals or a clean, safe indoor environment—which would you prefer?
What is Sick Building Syndrome?
Modern homes use many building materials made with chemical substances. Sick Building Syndrome refers to health issues like dizziness and headaches caused by breathing air containing volatile chemicals from these materials.
1 in 13 people is said to have Multiple Chemical Sensitivity. Indoor air purification is essential for healthy living.

- ✓ Long-lasting beauty (antioxidant effect)
- ✓ Creates an aging-care space
What is Body Oxidation & Reduction?
Body "oxidation" occurs when oxygen we breathe transforms into reactive oxygen species that damage cells, causing aging and disease.
"Reduction" is the opposite of oxidation. When oxidized cells gain hydrogen (electrons), they return to stable cells, helping recover from fatigue, prevent aging, and improve overall health.
Apples turning brown is also oxidation
Mechanism
How Plant Catalysts Work
Space that oxidizes = ages the body
- × Synthetic chemicals
- × Odors & dirt
- × Mold, bacteria, viruses
- × Air fresheners & deodorizers
- × Disinfectants
- × Fabric softeners & synthetic detergents
Plant reduction action "decomposes"
Space that reduces = rejuvenates the body
- ✓ Body reduction effect
- ✓ Supports immune maintenance
- ✓ Antioxidant prevents aging
- ✓ Antibacterial & antioxidant
- ✓ Static control
- ✓ Protects beneficial bacteria
- ✓ Indoor air purification
- ✓ Decomposes harmful substances
Spending time in an HPcure-coated room is proven to reduce oxidation in the body.
The effect was verified through ORP (oxidation-reduction potential) measurements using medical devices approved by Japan's Ministry of Health, conducted by NPO Japan ORP Measurement Verification Association.
ORP value changes over time after entering a plant catalyst-treated room
ORP Value (mV)
ORP values gradually decreased after entry. Body potential changed from oxidation to reduction tendency.
Randomly selected subjects of various ages and genders entered a plant catalyst-treated room for 90 minutes without eating, drinking, or electromagnetic exposure. Saliva samples were collected at intervals to verify the effect.
Oxidation, Reduction & ORP Values
ORP (Oxidation-Reduction Potential) indicates oxidizing or reducing properties. Positive values indicate high oxidizing power, while negative values indicate superior reducing power. ORP values are also important in fertility treatment—high sperm ORP (oxidation) is one cause of infertility.
Doctor's Recommendation
HPcure Coating (Plant Catalyst) Recommendation
~ From the Frontline of Preventive Medicine ~ Prevent "Oxidation = Aging" and Extend Healthy Lifespan
Through years of working with patients in preventive medicine, I've strongly felt the importance of the perspective: "How do we maintain health before illness occurs?"
From a preventive medicine standpoint, I emphasize "oxidation" as a key concept. It's no exaggeration to say that "aging, disease, and injury all begin with body oxidation."
Unfortunately, modern homes use many chemical substances like formaldehyde, thinner, and toluene. These chemicals promote "oxidation = aging" and cause chemical sensitivity and various diseases.

Innovation
An Innovative Building Material: Plant Catalyst
What I'm focused on is an innovative building material called "plant catalyst." This material, which applies the natural power of plants, not only decomposes harmful indoor chemicals but remarkably has been scientifically proven to lower the oxidation-reduction potential (ORP) in the air, creating a reducing environment opposite to oxidation.
A space with low ORP (non-oxidized) is like a forest bath for our bodies—refreshing and energizing. By applying plant catalyst to your home, you can unconsciously suppress body oxidation and support immune function maintenance in daily life.
Plant catalyst has over 18,000 installation records, and many people have experienced the difference in air quality and physical condition. It costs less than building with natural materials like solid wood floors or plaster, and since it only coats over vinyl wallpaper or flooring, it can be introduced without altering your home's design—reasons why it's widely accepted.
To extend healthy lifespan and live longer with higher quality of life, I believe future homes should be spaces that actively "prevent" disease, not just places to live. Housing construction companies need to actively work on this with concrete measures, and plant catalyst should be a definite step toward that realization.
Please take this opportunity to gather detailed information about plant catalysts and seriously consider incorporating them into your home. By changing your home's air, your healthy lifespan will surely change significantly.
Fertility & ORP Values (Oxidation-Reduction Potential)
ORP values are also important in fertility treatment—high sperm ORP (oxidation) is one cause of infertility.
Simply spending time in a plant
catalyst-treated room suppresses oxidation.
It has been proven that ORP values decrease 40 minutes after spending time in a plant catalyst-treated room.
■ ORP value changes over time (mV)
↓ ORP value gradually decreases

Frequently Asked Questions
Q
How long does construction take?
[Floor]
For areas of approximately 100 sq. m, construction can be completed in one day. We will inspect the progress the following day.
[Walls & Ceiling]
For walls and ceilings with a floor area of approximately 100 sq. m, construction can be completed in one day. We carefully apply four layers.
*If furniture needs to be moved or prior cleaning is required, additional time will be required. Please contact us for details.
Q
What types of floors, walls, and ceilings can be coated? Can it be applied to solid wood floors or painted walls?
[Floor]
Compatible with standard flooring materials and underfloor heating. For solid wood flooring, we recommend installing it on the ceiling and walls to maximize the properties of the material.
[Walls & Ceiling]
Installation is typically performed on vinyl wallpaper. Installation is also possible on existing wallpaper. Installation may not be possible on existing wallpaper if it is dirty or yellowed, so please consult with us.
*If installation is required after repairing stains or scratches, an additional fee will be charged.
Q
How long will the coating last? What is the warranty period?
[Floors]
We offer a 10-year warranty against peeling of floor coatings. However, peeling caused by customer use is not covered by the warranty.
[Walls & Ceilings]
The effect lasts until the applied wallpaper (vinyl wallpaper) is removed. Wallpaper (vinyl wallpaper) generally has a lifespan of 10 years, so the effect will last approximately 10 years. We will respond promptly to any repairs due to poor installation.
Q
Is any care required after coating?
[Floor]
No special care such as waxing is required.
[Walls & Ceiling]
No special care is required. It prevents dust from accumulating, making cleaning easier.
