What cures illness faster? Such as fever, cold and flu. Medicines or home remedies?

None: To be honest with you - none of the listed will cure it faster. It depends on your immune system and the severity of the flu. Both medications and home remedies only give you symptomatic relief. Tamiflu (oseltamivir) has been shown to shorten the flu for about 24 hours, but I've not been impressed with this medication and it is only effective if taken withing the first 24 hours since the onset. ...Read more

My toddler vomitted for several hours yesterday without fever nor diahra. Today she is back to normal. I wonder what illness could she have?

May not have been il: A kid can certainly have a brief vomiting episode from an infectious trigger & viruses are most common. However, given toddlers interest in exploring the world & using their taste buds to test their curiosity; this could have been related to ingesting a foreign substance.

I have fever body pain and itching. Itching is not too much. Fever is 100. Any idea from which illness I am suffering from. Anything seriouu?

Likely viral illness: The most common cause of elevated body temperature/fever is viral illness/infection. It is a defense mechanism your body is mounting in attempt to rid off the infection quicker--heat speeds up chemical reaction, thus body can work a bit quicker. If it is mild and not causing symptoms for you, leave it alone. If too high, motrin/tylenol as needed for comfort. Consult doc if much worse. Good luck. ...Read more
