Gotu Kola when added to a facial mask to rejuvenate and regenerate the skin and strengthen the tissues. Centella Asiatica has long been recognised for its healing activity. The principal modes of action of Da Wan ointment are related to the ability of Centella Asiatica to influence the inflammatory process in the wound healing cascade and its ability to promote Type 1 and Type 3 collagen balance. The immature thickened wound is characterised by a prolonged inflammatory stage and an abundance of Type 3 collagen. The promotion of Type 1 collagen production and the winding down of the inflammatory process is directly influenced by Centella Asiatica, as manifested by improved wound healing and scar formation. This inflammatory modulation property of Centella Asiatica may stop the conversion of the myofibroplasts, the cell type known to be associated with thickened, keloid type scars.
