Kuromoji Care Aroma Spray <Relax> - noi

Kuromoji has a rich, sweet and spicy aroma

Kuromoji is an important aromatic wood that inspired us to start up noi after we were struck by its scent in the forests at the foot of Mount Fuji.

As its name suggests, this plant has branches that look like black spots, and in spring it produces small yellow flowers along with green new shoots, in summer it grows lush green leaves, turns yellow in autumn, and in winter it loses its leaves, leaving only the branches to wait for spring.

It is a Japanese native fragrant wood. It is known as the "Japanese Rosewood" because of its rich, sweet, spicy and elegant aroma. In particular, the Kuromoji from Mt. Fuji has a strong citrus scent. Just pour in hot water and you're ready to make tea. It can be made into an herbal tea , and essential oils can be extracted through steam distillation.

At noi, we hand-pile Kuromoji from the foothills of Mt. Fuji and slowly dry it at low temperatures for long periods of time to make herbal tea, and we also extract essential oils through steam distillation to create home and self-care products.

Kuromoji as a herbal medicine

In Japan, it has long been used as a medicinal herb called "Usho."
Camphor is effective in promoting restful sleep, regulating gastrointestinal function, and treating phlegm, coughs, and bronchial problems.

Also, because it has strong antibacterial and germicidal properties, it was used to prevent colds, as toothbrushes during the Edo period, and even today as toothpicks in high-end restaurants.

Recent studies have confirmed that it has anti-cancer effects against human leukemia cells (HL60 cells) and blocks influenza viruses by more than 99.5%.

The effects of Kuromoji essential oil

The aromatic components of Kuromoji are mostly linalool, but also contain carvone, geraniol, limonene, 1,8-cineole, alpha-pinene, camphene, and other compounds, which provide a variety of beneficial effects.

- Relaxing and sedative effects

Linalool provides a stable sedative effect, relieving irritation and tension and relaxing the mind and body.

- Improved sleep

Linalool prevents the brain from waking up during the night and promotes continuous sleep. Linalool usually promotes impaired judgment, but it has been confirmed that the ingredients in Kuromoji do not impair judgment.

- Antibacterial effect

Kuromoji essential oil has antibacterial properties against tooth decay bacteria, periodontal disease bacteria, and Candida bacteria.

- Relief of skin problems

It also has antibacterial, sedative and anti-inflammatory properties, which help relieve skin problems. By applying it to areas affected by skin diseases such as atopic dermatitis and eczema that cause itching and inflammation, or to areas affected by insect bites, it helps to reduce symptoms and maintain healthy skin.

- Respiratory support

The aromatic components of Kuromoji help support the respiratory system by expanding the airways and promoting mucus secretion. This helps relieve symptoms such as stuffy nose and bronchitis, and makes breathing smoother. It is especially effective when used for colds and allergies.
