【Efficacy and Functions of Di Yu】

Studies have shown that Di Yu has an improvement effect on swelling caused by inflammation and has inhibitory effects on various bacteria such as Escherichia coli, Shigella, and Proteus.

Pharmacological studies have also shown that Di Yu has an antiemetic effect and can inhibit emesis caused by digitalis.
【Usage of Di Yu】
To treat dysentery (bloody or watery): Take 2 qian (about 7.5 grams) of Bai Di Yu, stir-fry 5 Wu Mei (Chinese plum), and take 1 qian (about 3.75 grams) of Shan Cha. Decoct in water and take orally. Use brown sugar as an adjuvant for red dysentery and white sugar for white dysentery.
To treat rectal bleeding: Take 4 liang (about 150 grams) of Di Yu and 3 liang (about 112.5 grams) of Zhi Gan Cao (honey-fried licorice). Take 5 qian (about 18.75 grams) each time, decoct in 2 cups of water, add 1 qian (about 3.75 grams) of Sha Ren (cardamom) powder, simmer until half a cup remains, and divide into two doses.
