1. What is Polygonum Cuspidatum?

Polygonum Cuspidatum, also known as Reynoutria japonica or Japanese knotweed, is a large, herbaceous perennial plant. It is native to East Asia, including Japan, China, and Korea. This plant typically grows in a variety of habitats, such as along riverbanks, in waste areas, and on mountain slopes.
It has a stout, hollow stem that can grow up to several meters in height. The leaves are broad, oval - shaped, and have a pointed tip. The plant also produces small, white or greenish - white flowers in late summer or early autumn.

2. How is the Polygonum Cuspidatum Extract Obtained?

The extraction of Polygonum Cuspidatum is a multi - step process.

1. First, the plant material (usually the roots and rhizomes) is collected. It is important to ensure that the collection is done sustainably and in accordance with relevant regulations.
2. Next, the collected material is dried. Drying helps to remove moisture and preserve the plant material for further processing.
3. Then, various extraction methods can be used. One common method is solvent extraction. For example, ethanol or methanol can be used as solvents. The dried plant material is soaked in the solvent for a certain period of time. During this process, the active compounds in the plant are dissolved into the solvent.
4. After that, the solvent is removed through evaporation or other separation techniques. This leaves behind the concentrated Polygonum Cuspidatum Extract.
