Qigong is meditation in movement. Taiji would be included as a form of Qigong. Qigong is a profound method of achieving health, spiritual power and great longevity. Like yoga, Qigong is based on routines that were developed by masters, some many centuries ago. Most Qigong is slow moving and requires (and develops) great concentration. Over time, Qigong builds great, sustainable strength in all parts of the body, excellent flexibility, free and excellent blood circulation, and smooth flow of Qi throughout the body. Many of the same formulations used for fitness or for yoga would be useful for the Qigong practitioner. Of course, Qigong and tonic herbalism are both based on Yin and Yang principles and upon the Three Treasures inherent in life. They were developed by the same masters in tandem over the past three thousand years. So the products we will suggest here are ones inherent in the system.
