1. Purple Amaranth Porridge Fresh purple amaranth is equal to japonica rice. After the roots are removed, the amaranth is washed and chopped, and porridge is cooked with japonica rice. Take it twice a day 10- 15 days. Amaranth is sweet and cool, which can clear away heat, cool blood and dissipate blood stasis. Making porridge is helpful to the physical recovery of patients with rectal cancer.

2. Walnut lotus seed cake: a certain amount of walnut kernel, a certain amount of kernel-removed lotus seed meat, and a proper amount of Euryale ferox powder. The total amount of glutinous rice is more than that of walnut kernel and kernel-removed lotus seed meat. Boil walnuts and lotus seeds in water and mash them. Soak glutinous rice in water for 2 hours, put it in a basin filled with peach paste lotus seed paste and Gordon Euryale seed powder, steam it in water, cut it into pieces after cooling, and sprinkle with a layer of sugar. Take it once in the morning and evening, 10- 15 days as appropriate. This is a beneficial dietotherapy method for rectal cancer, which can warm the kidney, strengthen the spleen and thicken the intestine to stop diarrhea.
