Hello, I'm from Changbai Mountain, which specializes in selling and wholesaling specialty products in Northeast China. Auricularia auricula is also one of our main specialty products. Auricularia auricula can clear away lung heat, but it doesn't have the effect of tonifying kidney. Lycium barbarum is a common medicinal material for tonifying kidney, and it is also a common ingredient for making soup and soaking wine at home. Of course, the northeast specialties for tonifying kidney include velvet antler, deer blood and deer whip.
