6. Immunity and regeneration: Aloin A, trauma hormone and polysaccharide peptide mannan (Ke-2) have the functions of resisting virus infection, promoting wound healing and recovery, diminishing inflammation and sterilization, clearing away heat and reducing swelling, softening skin and maintaining cell vitality. Gel polysaccharide combined with guaiacic acid also has wound healing activity, and is an ideal drug for treating trauma (hemorrhagic trauma and non-hemorrhagic trauma) without leaving scars.
