Mr Cao's treatment is suitable for children because it needn't oral antiphlogistics and injection. There is no pain during treatment period. The recipe is a kind of black medical powder with fragrant smell. It only can be put inside the ear for treatment.

Operation processes:

1. Pustule and other worthless fellows should be cleared away from ears before applying the powder.

2. Put the medical powder into the ear carefully till it is full.

3. Plug absorbent cotton in the ear and cover the ear.

4. Same procedures as above for the changing of medicine the next day. It will be cured during 2-7 days depending on the individual's illness condition.

Since the first day, the medicine has been full, how to add medicine the second day? Some people may ask this kind of questions. Here we answer as follows. The medicine can be absorbed by the ear itself. Even after the ear is fine and there are still something left in the ear, you also needn't worry because it will be absorbed slowly by the ear. Some patients may can not add more medicine inside the third day or forth day. If there are no worthless things, then you needn't add more medicine inside. If the condition is still not good, you should carefully get rid of the cube of medicine outside and then add more medicine.

Remarks:

1. The medical powder is not to be taken orally and the patient should be responsible for this result caused by his own mistake.

2. The medicine will affect during 2-3 days and you are forbidden to scrub it.

3. For the child patients, the hands should be controlled because it may result unforeseen matters if medicine put in child's mouth.

4. The people for adding medicine should be responsible specially.
