Importance of Study

Culture plays a significant role in the type of CT used

Yoga has origins in India7 Tai Chi & Qi Gong have origins in China8

There is an influence of culture in the use of complementary therapies.

Effects of this influence in alternate practices may be unknown.

We must further understand the relationship between culture and complementary therapies to allow us to bridge the gap between

conventional and complementary medicine.
