The Bronchial Mudra is very useful for the treatment of asthma as they have an impact on the biological map on the brain. This can be manipulated through the mudra in order to produce a positive effect on your autonomous nervous system, which controls your heart rate and breathe rate.
Place the little finger at the base of the thumb, the ring finger on the upper thumb joint, and the middle finger on the pad of the thumb. Extend the index finger. For an acute attack of asthma, use this mudra for 4 to 6 minutes or until breathing has become normal.
Inhalation: Direct your consciousness into your abdomen, stomach, chest, throat, forehead and top of the head. Hold breathe for 5 seconds.
Exhalation: Direct your consciousness from top to bottom and count backward from 7 to 1. Wait patiently until the impulse to inhale comes. Now direct the consciousness back to the top again while inhaling. The pauses after inhaling and exhaling are very important here.
Affirmation: Every breathe gives me strength. It strengthens my body, mind and soul.
