Toxins are a great hindrance for any cure. Unless they are removed first, practising yoga may not give much benefits, as the energy generated through Asana and Pranayama will be used up to eliminate these toxins, and not for the actual healing. It is because, the body views toxins as life threatening, and uses all the energy it can gather to expel them.
In Hatha Yoga, there are six purifying practices- Neti, Dhauti, Basti,Nauli, Tratak and Kapalbhati. Of them all, Nauli and Basti are difficult practices and can be skipped. The other four are most important. Dhauti washes the digestive tract while Neti clears the nasal passage-both are extremely beneficial in today's highly polluted world. The last two practices are meant to energize the brain and clear unwanted elements from it.
