Collection: The Scent and Effects of Kuromoji

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, Kuromoji has been traditionally utilized as a herbal medicine known as "Usho." It is known for its effects in promoting sleep, regulating gastrointestinal function, and addressing respiratory issues such as phlegm and coughs.

Additionally, due to its strong antibacterial and antiseptic properties, it has been used for preventing colds. During the Edo period, it was even used as a toothbrush and continues to be used today as toothpicks in high-end restaurants.

Recent research has also confirmed its anticancer effects against human leukemia cells (HL60 cells) and its ability to block influenza viruses by over 99.5%.
