==Role in traditional Chinese medicine==
The ''[[Huangdi Neijing]]'' ''(''"The Yellow Emperor's Classic of Medicine", circa 2nd century BCE) is historically credited with first establishing the pathways, called [[meridian (Chinese medicine)|meridians]], through which qi allegedly circulates in the human body.<ref>{{cite book|last1=Veith|first1=Ilza|title=Huang ti nei ching su wên = The Yellow Emperor's Classic of Medicine|date=1949|publisher=Williams and Williams|location=Baltimore|isbn=978-0520229365|edition=reissued, with a New Preface by Ken Rose; Berkeley, University of California Press, 2002 }}</ref>{{Page needed|date=January 2017}}<ref name="Lawson-Wood">{{cite book|last1=Lawson-Wood|first1=Denis|last2=Lawson-Wood|first2=Joyce|title=Acupuncture Handbook|date=1983|publisher=Health Science Press|pages=4, 133}}{{ISBN missing|date=November 2015}}</ref>

In traditional Chinese medicine, symptoms of various illnesses are believed to be either the product of disrupted, blocked, and unbalanced qi movement through meridians or deficiencies and imbalances of qi in the [[Zang Fu theory|''Zang Fu'' organs]].<ref name="Lawson-Wood"/> Traditional Chinese medicine often seeks to relieve these imbalances by adjusting the circulation of qi using a variety of techniques including [[herbology]], [[food therapy]], physical training regimens ([[qigong]], [[tai chi]], and other martial arts training),<ref>{{Cite book|last=Wu|first=Kung-tsao|title=Wu Style Tai Chi Chuan|trans-title=Wu Family T'ai Chi Ch'uan |script-title=zh:吳家太極拳|publisher=Chien-ch'uan T'ai-chi Ch'uan Association |orig-year=1980|year=2006|isbn=978-0978049904|title-link=Jianquan Taijiquan Association}}</ref>{{Page needed|date=March 2017}} [[moxibustion]], ''[[tui na]]'', or [[acupuncture]].<ref name="Lawson-Wood"/>{{rp|78}}The cultivation of Heavenly and Earthly qi allow for the maintenance of psychological actions<ref>{{lang|zh|李中梓}}, and {{lang|zh|江潤祥}}.

The [[nomenclature]] of Qi in the human body is different depending on its sources, roles, and locations.<ref name=":0">{{Cite web|url=https://www.orientmama.com/journal/what-is-qi-in-chinese-medicine|title=What is Qi in Chinese medicine?|date=23 April 2018|website=The Journal of Chinese Medicine on Orient Mama|access-date=29 April 2018}}</ref> For sources there is a difference between so-called "[[Yuanqi|Primordial Qi]]" (acquired at birth from one's parents) and Qi acquired throughout one's life.<ref name=":0" /> Or again Chinese medicine differentiates between Qi acquired from the air we breathe (so called "Clean Air") and Qi acquired from food and drinks (so-called "Grain Qi"). Looking at roles Qi is divided into "Defensive Qi" and "Nutritive Qi".<ref name=":0" /> Defensive Qi's role is to defend the body against invasions while Nutritive Qi's role is to provide sustenance for the body. To protect against said invasions, medicines have four types of qi; cold, hot, warm, and cool.<ref name=":2">Yang, Shou-zhong (1998). ''The Divine Farmer's Materia Medica: A Translation of the Shen Nong Ben Cao Jing''. pg. xii</ref> Cold qi medicines are used to treat invasions hot in nature, while hot qi medicines are used to treat invasions cold in nature.<ref name=":2" /> looking at locations, Qi is also named after the [[Zang-fu|Zang-Fu organ]] or the [[Meridian (Chinese medicine)|Meridian]] in which it resides:<ref name=":0" /> "Liver Qi", "Spleen Qi", etc. Lastly, prolonged exposure to the three evil qi (wind, cold, and wetness) can result in the penetration of evil qi through surface body parts, eventually reaching [[Zang-fu|Zang-Fu organs]].<ref>Hong-zhou Wu, et al.

A qi field (''chu-chong'') refers to the cultivation of an energy field by a group, typically for healing or other benevolent purposes. A qi field is believed to be produced by visualization and affirmation. They are an important component of [[Wisdom Healing Qigong]] (''Zhineng Qigong''), founded by Grandmaster Ming Pang.<ref name="Gu">{{cite book|last1=Gu|first1=Mingtong|title=Wisdom Healing (Zhineng) Qigong: Cultivating Wisdom and Energy for Health, Healing and Happiness|date=2011|location=Petaluma, California|publisher=Chi Center|isbn=978-0983504306|pages=61–80}}</ref><ref name="Gu2">{{cite book|last1=Gu|first1=Mingtong|title=An Introduction to Wisdom Healing Qigong|date=2009|location=Petaluma, California|publisher=Chi Center|pages=30, 46–47}}{{ISBN missing}}</ref><ref name="Ooi">{{cite book|last1=Hin|first1=Ooi Kean|title=Zhineng Qigong: The Science, Theory and Practice|date=2010|publisher=CreateSpace|location=North Charleston, South Carolina|isbn=9781453867600}}</ref>{{Page needed|date=March 2017}}
