Polymers can be classified in ways that reflect their chemical makeup, or perhaps more importantly, their properties and applications. Many of these factors are strongly interdependent, and most are discussed in much more detail in subsequent sections of this page.
Centella asiatica (Gotu Kola) is a well known herb traditionally used in the treatment of skin damage as well as for circulatory enhancement. This is a specialized extraction employed for the concentration of the active constituents for enhanced therapeutic benefits to the skin.
