所谓的药食同源，主要以兼具药用价值和食用特性的天然食材为主，其核心在于利用食物的四性指寒、热、温、凉和五味指酸、苦、甘、辛、咸及归经属性调节人体机能，它们既能作为日常膳食的原料，又能在中医理论指导下发挥特定调理作用。比如生姜性辛、微温，归肺、脾、胃经，具有散寒解表、温中止呕、温肺止咳、解毒等功效，同时日常生活中又可以调味、熬汤、泡茶等；肉桂性味大热，辛、甘，归肾、脾、心、肝经，具有补火助阳、散寒止痛、温经通脉、引火归元等功效，日常中可以用来炖汤调味等；茯苓味甘、淡，性平归心、肺、脾、肾经，具有利水渗湿、健脾、宁心的作用，生活中也可以用来煮粥、煲汤、制作糕点等；陈皮味苦、辛，性温，归肺、脾经，具有理气健脾、燥湿化痰的功效，生活中可以泡水、煮粥、炖汤等；人参性微温，味甘、微苦，归脾、肺、心、肾经，具有大补元气、复脉固脱、补脾益肺、生津养血、安神益智等功效，日常生活中也可以用来炖汤、泡酒、入膳等；甘草性平味甘，归心、肺、脾、胃经，具有补脾益气、清热解毒、祛痰止咳、缓急止痛、调和药性等功效，生活中也可以用来泡水喝、煮粥、煲汤等，总之通过药食同源能辅助改善亚健康状态，预防慢性病或缓解轻微不适，能调理体质，增强免疫力，促进代谢等，但不能替代药物治疗疾病。

      The so-called "food and medicine sharing the same origin" mainly refers to natural ingredients that have both medicinal value and edible characteristics. Its core lies in regulating human body functions by utilizing the four natures of food, namely cold, hot, warm and cool, and the five flavors, namely sour, bitter, sweet, pungent and salty, as well as their meridian attributes. They can not only serve as raw materials for daily diets but also play specific regulatory roles under the guidance of traditional Chinese medicine theory. For instance, ginger is pungent and slightly warm in nature, and it belongs to the lung, spleen and stomach meridians. It has the functions of dispelling cold and relieving the exterior, warming and stopping vomiting, warming the lungs and relieving cough, and detoxifying. Meanwhile, in daily life, it can also be used for seasoning, making soup and brewing tea, etc. Cinnamon is highly hot in nature, pungent and sweet in taste, and enters the kidney, spleen, heart and liver meridians. It has the functions of tonifying fire and assisting Yang, dispelling cold and relieving pain, warming meridians and promoting blood circulation, and guiding fire back to its origin. In daily life, it can be used for stewing soups and seasoning, etc. Poria cocos is sweet and light in taste, neutral in nature, and enters the heart, lung, spleen and kidney meridians. It has the functions of promoting diuresis and removing dampness, strengthening the spleen and calming the heart. In daily life, it can also be used to cook porridge, make soup and produce pastries, etc. Dried tangerine peel is bitter and pungent in taste, warm in nature, and belongs to the lung and spleen meridians. It has the functions of regulating qi, strengthening the spleen, drying dampness and resolving phlegm. In daily life, it can be used to make tea, cook porridge, stew soup, etc. Ginseng is slightly warm in nature, sweet and slightly bitter in taste, and enters the spleen, lung, heart and kidney meridians. It has the functions of greatly replenishing vital energy, restoring the pulse and preventing collapse, tonifying the spleen and lungs, promoting the production of body fluids and nourishing blood, calming the mind and enhancing intelligence. In daily life, it can also be used to make soup, brew wine, and be incorporated into meals, etc. Licorice is neutral in nature and sweet in taste, and it belongs to the heart, lung, spleen and stomach meridians. It has the functions of tonifying the spleen and benefiting qi, clearing heat and detoxifying, eliminating phlegm and relieving cough, alleviating acute pain, and harmonizing the properties of other herbs. In daily life, it can also be used to make tea, cook porridge, and make soup. In short, through the principle of "food and medicine sharing the same origin", it can help improve sub-health conditions, prevent chronic diseases or relieve mild discomfort, regulate the constitution, enhance immunity, and promote metabolism. But it cannot replace drug treatment for diseases.
