This invention relates to the field of wound repair technology, and in particular to a wound repair patch containing aloe vera gel. By weight, the raw materials of the wound dressing containing aloe vera gel include: 20-25 parts aloe vera gel, 7-10 parts chitosan, 100 parts polyvinyl alcohol, and 8-12 parts white tea extract. Aloe vera gel has certain anti-inflammatory and antibacterial properties, promotes local metabolism, astringes wounds, and promotes cell regeneration. The wound dressing prepared by electrospinning has good breathability and can effectively absorb exudate from the wound, creating a relatively dry environment. However, an overly dry environment is not conducive to the repair and reconstruction of skin tissue. The amino acids and complex polysaccharides contained in the aloe vera gel in the dressing constitute natural moisturizing factors, which can replenish the lost moisture in the skin, quickly restore the function of skin collagen, and promote wound healing.
