Klebsiella macrocarpa* extract, and *
Alternaria rubra* extract, wherein the
mass ratio of
soybean lecithin, *Alnus macrocarpa* seed oil, *
Klebsiella macrocarpa* extract, and *
Alternaria rubra* extract is (1-5):(1-10):(0.1-3):(0.5-5). Compared with existing technologies, this invention uses multiple
plant extracts as active ingredients, employing a compounding of *Alnus macrocarpa* seed oil, *
Klebsiella macrocarpa* extract, and *
