Analysis:
Walnut, also known as Walnut, is said to have been brought back by Zhang Qian when he went to the Western Regions. It may be a specialty of northwest ethnic groups, including Hu cut, pepper and Hu Qin. It is now produced in Taihang Mountain, Xinjiang, Shandong and other semi-mountainous areas or hilly areas, and is drought-tolerant.
Walnut is known as "longevity food", which is sweet and warm. It can tonify lung and kidney, nourish yin and yang, moisten intestines and relieve constipation, and relieve cough and asthma. Compendium of Materia Medica says: "Treat deficiency cold, cough and asthma, lumbago and leg pain." It is called "the key medicine for strengthening muscles and bones" in medical enthusiasm. "Kaibao Materia Medica" said that eating walnuts often can: "make people fat and healthy, moisturize muscles and blacken hair." Walnut kernel can be used to treat impotence, nocturnal emission, soreness of waist and knees, insomnia, amnesia, frequent urination, deficiency of qi and blood, dysmenorrhea and other symptoms.
Modern walnuts are mainly rich in fat, including linoleic acid glyceride, linolenic acid glyceride and oleic acid glyceride, which is beneficial to reduce the increase of cholesterol in blood and is suitable for patients with arteriosclerosis and cardiovascular and cerebrovascular diseases. Walnut contains high phospholipids, which can maintain normal cell metabolism, enhance cell vitality and prevent brain cells from declining. It is a good brain food. Choline in phospholipids can promote fat metabolism in liver cells, thus reducing the degree of fatty liver. Feeding peach kernels to mice has also been proved to have the effects of reducing blood lipid and delaying aging. Walnut contains more lysine, which can increase serum albumin and maintain body weight, which is beneficial to the treatment of consumptive diseases such as tumor and tuberculosis. Moreover, walnut contains juglone, which has inhibitory effect on some transplanted tumors.

It is also reported that boiled eggs with fresh walnut branches are folk remedies for cervical cancer.
