Shiso’s essential oil is collected in Hokkaido. Shiso and shikka are both members of the shiso family. The essential oil of shiso is made by applying the same technology used to extract the essential oil of shikka. Shiso essential oil is made from green shiso.


Shiso essential oil is used as an essential oil for aromatherapy, which is a very small portion of the production. Most of it is used as a natural flavoring agent in food products, such as dressings.

The main component of shiso essential oil is perillaldehyde, which accounts for about half of all the components of shiso essential oil.
Perillaldehyde has a strong antibacterial and antiseptic effect, and is effective in preventing food poisoning.
It also contains many antihistamine components. Perillaldehyde has been shown to be effective in treating atopic dermatitis, but it should not be recommended to customers easily due to research results showing that it may cause skin sensitization.
Be sure to use a small amount first.
