Hello...it is necessary to know for me that why u go for yr mothers TSH test... It's a routine test that is done or she has any major components that leads u to the test..anyway If she doesn't have any major complaints n as u say it is recently diagnosed Homeopathy is the best option n definitely help her in a better way... If  she has any major issues then start both simultaneously n letter on with supervision u can continue Homeopathic medicine only...
