Hi Lalitha You can recite Aditya Hridyam http://www.indusladies.com/forums/23264-post220.html or Sri Raamaraksha Stotram for good health and Sankatamochana Sri Hanuman Ashtakam for coming out of obstacles
I hope we can recite Dhanvantri mantram for good health. Also Anjaneyar slokams can be recited for good health and also for no obstacles.
Dear Chivukula, Can you please help me by guiding from where I can get these slokas in tamil. Sri Raamaraksha Stotram and Sankatamochana Sri Hanuman Ashtakam
