Used for pain relief, infertility, turning babies from breech to head down, and various other conditions.
Qi, which is loosely called Energy, travels along Meridians in the body, of which there are thirteen, six on each side and one in the middle (although there are theories that there are more or less Meridians). If there is an impediment to the transmission of energy along the meridians, disability, disease or death can occur. The practitioner determines by history and examination which Meridian and locus on the meridian is affected and piquers those points to unblock the meridian so that energy can travel unimpeded and health is restored.
Acupuncture is generally more accepted in the western world than Ayurveda.
