It is currently the season for citrus fruits. Oranges are neutral in nature and sweet and sour in taste. They have the effect of promoting fluid production and relieving cough, and are used for symptoms of stomach and intestinal dryness and heat; they also have the effect of harmonizing the stomach and promoting urination, and are used for conditions such as lung heat and cough.
Research by experts has confirmed that fresh orange juice contains a substance with strong anti-cancer activity called "nomilin," which can decompose carcinogenic chemicals, inhibit and block the growth of cancer cells, and double the activity of detoxifying enzymes in the human body. It prevents damage to the cell nucleus by carcinogens and protects the integrity of genes. The peel, seeds, and white network of the orange can all be used for medicinal purposes. The dried orange peel is called "dried tangerine peel" (because the older it is, the better its medicinal effect). The volatile oil in dried tangerine peel can enhance the contractility of the heart, dilate the coronary arteries, and increase blood flow; it can reduce the permeability of capillaries; dilate the bronchi, and has an anti-asthmatic effect; it can also promote the secretion of digestive fluids and expel gas from the intestines. The white "orange network" on the pulp contains vitamin P, and has effects such as dredging collaterals, resolving phlegm, regulating qi, and eliminating stagnation. Orange seeds have the effect of regulating qi and relieving pain, and can be used to treat hernia, back pain, and other conditions.
In summary, oranges are an excellent fruit for men, women, and the young, especially for the elderly, and patients with acute and chronic bronchitis and cardiovascular diseases. Of course, they should not be eaten in excess. Eating too many can easily lead to "heatiness," causing symptoms such as dry mouth, dry throat, and constipation, and can also trigger adverse effects such as stones and induce abdominal pain. Patients with internal heat, fever, infectious diseases, and women in menopause should try to eat as few as possible.
