This extract is obtained from the flowers of the Sophora japonica tree, which is native to Asia.

2. Types of Sophora Japonica Flower Extract

2.1. Water - based Extract

- Features: Water - based extraction is a relatively simple and natural method. It mainly extracts water - soluble compounds from the Sophora japonica flower. The resulting extract is often milder in nature. - Benefits: It is suitable for those who may have a more sensitive system. It can retain some of the delicate nutrients and phytochemicals present in the flower. For example, it may contain water - soluble flavonoids which are known for their antioxidant properties. - Applications: Commonly used in the formulation of some herbal teas or mild topical products. For example, in some skin - care products designed for sensitive skin, the water - based Sophora japonica flower extract can provide gentle soothing and antioxidant effects.

2.2. Ethanol - based Extract
