Faith healing has to be taken with a pinch of salt. When nothing happened, the healer will say that you don't have enough faith.
To correct drifter's misconceptions that Qigong is faith based. Of course, there are many extraordinary claims to the power of Qi which should not be taken seriously including extraordinary power depicted in Kung Fu movies.
Qigong is basically a form of breathing exercise. There are many medical research done on Qigong. Read the below extract from widipedia on Qigong and the application in Martial Arts:
Qigong, chi kung, or chi gung (simplified Chinese: 气功; traditional Chinese: 氣功; pinyin: qìgōng; Wade–Giles: chi4 gong1; literally "Life Energy Cultivation") is a practice of aligning breath, movement, and awareness for exercise, healing, and meditation.[1] With roots in Chinese medicine, martial arts, and philosophy, qigong is traditionally viewed as a practice to cultivate and balance qi (chi) or what has been translated as "intrinsic life energy".[2] Typically a qigong practice involves rhythmic breathing coordinated with slow stylized repetition of fluid movement, a calm mindful state, and visualization of guiding qi through the body.[3] Qigong is now practiced throughout China and worldwide, and is considered by some to be exercise, and by others to be a type of alternative medicine or meditative practice.[4] From a philosophical perspective qigong is believed to help develop human potential, allow access to higher realms of awareness, and awaken one's "true nature".[5]
Martial arts training
The practice of qigong is an important component in both internal and external style Chinese martial arts.[5] Focus on qi is considered to be a source of power as well as the foundation of the internal style of martial arts (Neijia). T'ai chi ch'uan, Xing yi, and Baguazhang are representative of the types of Chinese martial arts that rely on the concept of qi as the foundation. [44] Extraordinary feats of martial arts prowess, such as the ability to withstand heavy strikes (Iron Shirt, 鐵衫) [45] and the ability to break hard objects (Iron Palm, 铁掌) [46] [47] are abilities attributed to qigong training.
