I have just get a pack of herbs from a Chinese medicine shop and will try your method too. Hopefully I can talk tomorrow....it is so difficult to deal with my son while I can't speak. :-( :-( :-(
My voice is partially back. Thanks to your advise. Also, I was told a secret receipt this morning while I am having my breakfast with my husband in a local tea shop.
a teaspoonful of sugar
mix it with an raw egg
pour hot boiling water and stir
Besides, you can alos take some "STAR FRUIT" Juice (add salt optionally), this is good for sore throat and can get your voice back quickly. Whenever there is sore throat I take one glass of Star fruit juice twice a day (no ice but room temperature to avoid stimulation) and help to ease the pain and dryness.
