Chinese Herbs for Spasmodic Dysphonia

My cousin recommended a good Chinese doctor and I went to his clinic for a general checkup. He gave me some Chinese herbs to boil and told me to drink the concoction. I saw the assistants make the herbal preparation. They were different barks, leaves and other tree parts. Each ingredient had a different measurement.

It tasted like tea, very bitter tea. But it wasn't that bad. Or perhaps since I'm used to chinese medicine (my grandmother used to let me drink deer's horn extract and other chinese medications), this tea tasted alright. A closer look would show the barks and leaves:

After 3 days of drinking the concoction, my voice sounds louder and it's not as hard to control anymore! I don't know what these herbs are, but they sure do help :-)
