第四医学是一门新兴的边缘学科，是本人通过调研和考察把绿色疗法升华而提出的，由于其指导思想符合了当前人们的需要，因此发展很快，当前从事第四医学工作者越来越多，但还有不少人对第四医学不够了解，为了使更多的人关注了解第四医学，下面就谈谈自己对第四医学的认识和理解。

      第四医学的形成是在人类的第四次大革命——健康革命启发下而诞生的。在人类历史的发展中，每次科学技术革命，无不给人类的社会生活带来巨大影响，农业革命使人们不必自相残杀，弱肉强食，人人可以温饱地生活;工业革命使劳动效率大大提高，使人们在短时间的劳作就可以安逸舒适的生活;信息革命又使时空缩短，大大提高了劳动生产率，使人们的休闲时间大大超过了劳作时间。当前所面临的是人类的第四次大革命——健康革命。它的目标使人们愉快、健康、长寿，高质量地渡过幸福的一生。要想达到这一目标就需要第四医学工作者来完成。第四医学包含了刮痧拔罐疗法、砭石疗法、按摩疗法、足疗、美容、心理学、理疗、合理运动、食疗等。
现在，心、脑血管病、癌症、糖尿病、精神性疾病、意外伤残及污染性的慢性病明显增加，而目前的医学对这些疾病常无良策。在这种情况下，自己设法维护自身健康的医学必然兴起，是任何力量也阻挡不了的必然趋势，“自我保健”这一兴起的医学——第四医学，也就瓜熟蒂落，应运而生了。

      第四医学就是绿色医学，自我保健医学，也可以叫做大众医学、家庭医学。它与第一医学（临床医学）、第二医学（预防医学）、第三医学（康复医学）相比，从理论到实践方法上都不相同。它不再仅仅以病和病人为对象，而是更加强调自我保护，倡导科学的自我保健，包括自我保健和相互保健方法的科学应用。当前，国内外医学界正在进行“医学目的”的学术讨论，提出医学应以提高人类的生命质量为目的，而不是局限于“治病救人，救死扶伤”。“自我保健”是人们为了自身的健康，自我发现，自我保护，自我处理或协同医院治疗的一种保健行为。自我保健服务是非职务性卫生保健服务。在这里人们从医疗服务机构的被服务者变成了促进自身健康的自我服务者。它所起到的健康效果是现有卫生服务体系难以达到的。
第四医学的内涵是：利用自己所掌握的医学知识和养生保健手段在不住医院，不求医生、护士的情况下，依靠自己和家庭的力量，对身体进行自我观察、诊断、治疗、护理和预防等工作。逐步养成良好的生活习惯，建立起一套适合自身健康状况的养生方法，以达到祛病强身、推迟衰老和延年益寿的目的。

      第一医学（临床医学）又称治疗医学。人类的祖先在最早的捕猎、劳动中受伤，他们为了生存便开始寻求草药或利用空气、水分、阳光等自然条件来治疗伤病，这就是最早的治疗医学。现在，由于X线、激光等先进医药技术的问世，治疗医学得到不断的完善与发展，所以，至今仍是人们生命健康的重要保证。
第二医学（预防医学）又称分子矫正医学。那是在发明显微镜，特别是18世纪中叶发现细菌之后，才发展起来的。当时人们惊奇地发现，原来许多疾病竟是一些小小的微生物作怪的结果。那么，能不能防止这些病菌侵入我们的机体呢？认识到防患于未然的重要性，于是便有了预防医学。近百年来，以婴幼儿开始接种疫苗等“预防为主”的原则对人们的健康起了很大的作用。
第三医学（康复医学）又称健康医学。随着社会生产力的发展，人们生活水平的提高，医疗技术的进步，伤残者、疾病后遗症者，要求康复的心理变得愈来愈强烈，于是保健康复医学便应运而生。目前，国内外保健康复医院，保健药品，保健器械层出不穷，对延年益寿，提高健康水平作出贡献。

      世界卫生组织（WHO）明确指出：健康不仅仅是没有疾病和衰弱，而是应该包含四个层次：一是身体健康。指人体结构完整，生理功能正常；二是心理健康。指具有责任心、自信心、爱心、情绪稳定、热爱生活、善于交往，有自控能力;三是道德健康。最高标准是无私奉献，最低标准是不损害他人利益。四是社会适应良好。指能适应当时复杂的环境变化。只有这四个方面都健全，才是完全健康的人。

      第四医学所追求的已不是“更好地治病”，而是“让人生活得更健康”！因为健康是金，是事业的前提、生命的基础：健康是乐，没有健康便享受不到生活的乐趣：健康是寿，只有身体健康、愉快地活着，才可“活得长久”：健康是智，智力的发挥要以健康作为后盾：健康是财，是人生最大的财富;健康是富，是每个人在这个世界上最大的权利，充分享受这一权利是最大的幸福;不求长生不老，但求老而不衰，是合理又可能的要求。第四医学康而福研制的康而福排毒、清咽丸。螺旋藻、乐多寿迪芬斯系列、灵芝、泗滨砭石刮痧板、床垫、床、砭石仪、砭石杯系列等，排毒保健产品，能使你身体健康，延缓衰老，加入康而福使您成为完全健康人。

目前，第四医学康而福培训基地建立的技术推广系统——康而福健康法，实际上就是典型的第四医学，它具有第四医学的一切特征：在康而福大学校里已经没有“大夫”和“病人”的严格界线，人人都是大夫，人人又都是病人，人人都在用康而福健康法维护自身和他人的健康。人人又都是自我保健受益者。人人都在为提高自身他人的生命质量，防病治病，康体健身和延年益寿而奋斗！第四医学康而福大学校热烈欢迎各位朋友早入加入康而福。
以上论文，不足之处望广大同仁指正。

The Fourth Medicine, as a rising frontier discipline brought forward by Professor Lv Jiru, a famous Taiwan specialist in the preventive medicine, has witnessed a rapid development owing to its ideas. Currently, there are more and more medical workers engaged in this field. However, lots of people only have a smattering of the knowledge about the Fourth Medicine. So, to help more people learn about it, I put forward my opinions in the following.

I.           Establishment of the Fourth Medicine
The Fourth Medicine came into being with the health revolution, the fourth great revolution. In the development history of human beings, each scientific and technical revolution has greatly influenced people's life: the Agricultural Revolution has put an end to the dog-eat-dog age and solved the problem of food and clothing; the Industrial Revolution has greatly improved the efficiency, making people enjoy a comfortable life while work for a shorter time and the Information Revolution has shortened the time and space, providing more leisure time for people. At present, people are faced with the health revolution, aiming to make people have a pleasant, healthy, longevous and high-quality life. To meet that end, the fourth medical workers need to make great efforts. The Fourth Medicine contains scraping (Gusha in Chinese) and cupping therapy, stone needle therapy, massotherapy, foot massage, body beauty, psychology, physiotherapy, reasonable movement and food therapy, etc.

Nowadays, cardio/cerebrovascular diseases, cancer, diabetes, mental diseases, traumata and the diseases caused by environmental pollution have markedly increased, while the current medicine always has little effect on such diseases. Thus, a medicine that makes people protect their health emerged as required and this medicine is the Fourth Medicine.

II.         What is the Fourth Medicine?
The Fourth Medicine, namely Green Medicine, Self Health-care Medicine, and also called Popular Medicine and Family Medicine, is different from the First Medicine (Clinical Medicine), the Second Medicine (Preventive Medicine) and the Third Medicine (Rehabilitation Medicine) theoretically and practically. The Fourth Medicine stresses self-protection, advocates scientific self health-care including the scientific application of the self health-care method and the mutual health-care method, instead of targeting diseases and patients. Currently, an academic discussion on the purpose of medicine has been undergoing both home and abroad and it puts forward such an end that the medicine shall improve the life quality of human beings instead of limiting to "cure the sickness to save the patient and heal the wounded and rescue the dying". Self health-care is such a behavior that people discover the disease and treat by themselves or with the cooperation of the hospital to guarantee their health. Self health-care services are non-post health-care ones. When people are receiving such services, they become a self-service person to promote self-health instead of a service-receiver. Of course, the effect of such services is unmatchable by the existing health service system.

The connotation of the Fourth Medicine is: by utilizing their medical knowledge and health protection methods and without the aid of doctors and nurses, people are able to carry out self observation, diagnosis, treatment, nursing and prevention with the help of their family. And gradually, they will from a good living habit and build a set of health-care methods fitting their health conditions, as a result, to remove diseases, strengthen their body, suspend the senescence and prolong their life.

III.        What Are the First Medicine, the Second Medicine and the Third Medicine?
The First Medicine (Clinical Medicine), also called Therapeutic Medicine, was the earliest medicine which can be traced back to human's ancestors who would use herbal medicines or natural conditions like air, water and sun to treat their injuries caused during hunting and working. For the moment, owing to antibiotic substances, X-line and lasers, this medicine has been greatly developed, so it is still an important guarantee for people's life health.

The Second Medicine (Preventive Medicine), also called Ortho-Molecular Medicine, came into being with the invention of microscopes, especially the discovery of bacteria in the middle 18th Century. At that time, people discovered surprisingly that many diseases originally were caused by some microorganism and began to wonder how to prevent the germina entering human body. People also began to realize the significance of nipping in the bud and as a result, the preventive medicine was put forward. For about one century, the principle of vaccination from the child has contributed a lot to people's health.

The Third Medicine (Rehabilitation Medicine), also called Health Medicine, emerged owing to people's increasing demand for rehabilitation from injuries and sickness sequelae and due to the development of social productive forces and the growth in the living standard and technical advancement in medical treatment technology. Presently, health-care rehabilitation hospitals, health-care medicines and apparatus dedicated to prolonging life and improving the health level have been emerging one after another both home and abroad.

IV.     Health Standards of the Fourth Medicine
World Health Organization (WHO) has clearly stated that health refers to more than being free of sickness and enervation, but contains four hierarchies: firstly, physical health, referring to the integrity of body construction and normal physiological functions; secondly, mental health, referring to one's sense of responsibility, self-confidence, love, emotional stability, life devotion, capability of communication and self-control; thirdly, moral health, the highest standard for which is selfless dedication and the minimum standard is not harming others' benefits; fourthly, social adaptation ability, referring to the adaptability to the complicated environmental changes. Only meeting the four standards can a person be called healthy.

V.       Pursuance of the Fourth Medicine
The Fourth Medicine aims to make people live healthier instead of better curing diseases. Health means gold, the precondition of one's career and the foundation of life; health means pleasure and without it, no pleasure can be found in life; health means longevity and only healthy and happy life can realize it; health means wisdom and is the supporter of intellectual performances; health means fortune and is also the most expensive in life; health means wealth and the maximum right for everybody to enjoy. People's courting for longevity instead of permanent-youth, for aging instead of senescence is a reasonable and possible requirement. Beijing Kang'erfu Health-care Product Company affiliated to China Academy of Traditional Chinese Medicine and Shaanxi Detong US-returned M.D. Medicine Science & Technology Co., Ltd. have produced Shuangnuoxi (SHNX), Tongtai, spirulina, Leduoshou and Difensi series products, which are helpful to people's physical health and able to postpone senescence. So join us!

VI.     Welcome to Enter the Fourth Medicine School

So, in Kang’erfu, everybody is both doctor and patient and protects self-health and others' health by utilizing the method of Lv. Everyone here has benefited from self health-care and strives for improving life quality, preventing and curing diseases, building body and prolonging life.
