My own ways to cure sore throat:
1)BOIL Chrysanthemum tea, add a small piece
of rock sugar ( very important ).
2)Green bean soup. Also add rock
sugar instead of normal sugar as rock sugar have 'cooling'
purpose.
3)Eat watermelon but do not over
eat. 2-3 slice will do.
4)Last method and also the best
way: Raw Lotus Roots juice. WHO DARE TO DRINK LIKE TAT? 
Add a little honey if you hate the raw taste.
FYI:
Lotus root is sweet and can be eaten as fruit, sliced and stir
fried, or stuffed with glutinous rice in its flue-shaped holes and
steamed as dessert. Tender young lotus roots are good for salads
while starchy mature lotus roots are good for making soups. Ground
mature lotus root powder makes wonderful thick soup and dessert
soup. It also stops diarrhea, clears Heat and improve appetite.
Lotus roots contain much iron, vitamins B & C. The rich fibre
content of lotus roots stimulates peristalsis and relieves
constipation. Drinking 2 to 3 glasses of lotus root juice a day can
stop bleeding of the esophagus an stomach (vomiting blood);
bleeding of the rectum, intestines or stomach (blood in feces);
nose bleeding or gum bleeding. Lotus root soup also serves similar
purposes. Patients with high fever can drink it cold, while those
with steady temperature should drink it warm. Drinking water
chestnut juice mixed with pear juice can help clear phlegm while
mixing it with grape juice and carrot juice eases dry tongues.
