Perilla leaves, a seemingly simple natural ingredient, have become the heart of Lá Mây’s household cleaning products thanks to a scientific and sustainable fermentation process. This is the journey from nature to technology, transforming lush green leaves into an effective, eco-friendly cleaning agent in every product.
To turn these humble leaves into a powerful cleaning component, we have developed a meticulous and advanced fermentation process. Each step is carefully executed to preserve the precious nutrients from nature while maximizing cleaning efficiency. This journey begins with selecting the freshest, highest-quality materials and sets the stage for a fully enclosed production cycle that surpasses conventional technologies in quality and sustainability.
PERILLA LEAF FERMENTATION PROCESS
The Essence of Nature - The Innovation of Science

The perilla leaf fermentation process at Lá Mây is not only a perfect combination of science and nature but also a testament to our commitment to quality and environmental responsibility. Every product is the result of a closed-loop process, from pristine green leaves to pure fermented solutions, delivering superior cleaning performance and absolute safety. With Lá Mây, every step of cleaning goes beyond caring for your home—it contributes to protecting a sustainable green environment for the future.
1. Harvesting and Selecting Perilla Leaves

The journey begins in clean farming areas, where perilla leaves are cultivated without harmful chemicals or pesticides. Each leaf is meticulously selected to ensure freshness and retain its natural nutrient content. Harvesting is carried out at the optimal stage of leaf development, when natural compounds such as polyphenols and flavonoids are at their peak.
2. Cleaning and Preparing Ingredients

After harvesting, perilla leaves are carefully washed with water to remove dirt and impurities. This process ensures the leaves are clean while preserving all their natural nutrients. The leaves are then finely chopped and lightly processed to prepare for the fermentation stage.
The perilla leaf fermentation process at Lá Mây is not only a perfect combination of science and nature but also a testament to our commitment to quality and environmental responsibility. Every product is the result of a closed-loop process, from pristine green leaves to pure fermented solutions, delivering superior cleaning performance and absolute safety. With Lá Mây, every step of cleaning goes beyond caring for your home—it contributes to protecting a sustainable green environment for the future.
3. Establishing a High-Tech Fermentation Environment
Once the perilla leaves are thoroughly cleaned, they are transferred into a closed fermentation system utilizing advanced technology to comprehensively control environmental factors. This is a critical stage that determines the quality of the fermented solution and its effectiveness in household cleaning products.
-
The fermentation environment is precisely controlled

The fermentation tanks are made from specialized stainless steel, ensuring they are corrosion-resistant and non-reactive with natural ingredients. The system is programmed to monitor and regulate temperature, humidity, and oxygen concentration throughout the fermentation process, maintaining optimal conditions for beneficial microorganisms. The temperature is consistently maintained between 30–37°C, the ideal range for lactic bacteria and enzymes to function at their best.
-
Eliminating the Risk of Cross-Contamination

To ensure purity and prevent harmful bacteria or impurities from entering, the entire system operates under sterile conditions. All materials and equipment that come into contact with the perilla leaves are meticulously sterilized using high-pressure steam before use. Furthermore, the pumps and lids of the fermentation tanks are designed to be completely sealed, allowing only necessary gases to pass through sterile filters.
