Tui Na - (Twee Nar) is a form of Chinese Remedial Massage based in the same theoretical understanding of the body as Acupuncture. It is similar to both Shiatsu and Thai Yoga Massage in style. The question of which was developed first, or who copied who, will vary depending on who you ask. So to save arguments let's just stick with the fact that these therapies developed alongside each other, with a healthy exchange of ideas and techniques. (But Tui Na came first!)
Although not as widely practiced in the West, it is a popular modality within China, where entire sections of hospitals are dedicated to Tui Na Massage practice. Often described as the Traditional Chinese equivalent of sports massage, Tui Na application can be used to treat a variety of symptoms and is an effective alternative to acupuncture for those unwilling or unable to be needled.
Digging Deeper Classically Tui Na was a Pillar of Chinese Medicine (The other three Pillars being Acupuncture, Herbs and Qigong). It included with bone setting techniques and manipulations akin to those used by both osteopaths and chiropractors. (technically they are the same but let's not open that can of worms.) Most of these techniques are no longer practiced as part of Tui Na and instead the focus is on the soft tissues, or in a traditional session, the meridians and Jing Jin.
Wait, Jing what? Jing Jin are the lines of tendons and connective tissue, as they relate to the meridian system. Handy when working without needles!
Treatment Specifics Traditionally Tui Na is performed fully clothed, through a blanket or towel. However for those who are a bit more adventurous, a selection of infused oils can be used instead. This is handy for both cases where the herbal or essential oil based oils boost treatment effects, and for those used to a more western style of massage. The long and short answer is, the choice is yours. If you'd like oils or to remain clothed, both can be used to great effect for both relaxation and specific conditions. The oils used are either a blend with Indonesian herbs to promote smooth flow of Qi and Blood, or an Alchemical mix of essential oils brewed in Cornwall. The aptly named Pirate Oil!
