I agree with the parent when it comes to things like the cold. I seriously don't understand people who take paracetamol and tons of other over the counter stuff for that. When it comes to allergies though (hay fever in my case) I can barely function without antihistamines (and with them I'm still a wreck). I haven't found any of the home remedies to be effective for it whereas in the case of the cold plenty of water and some lemon and ginger tea seems to improve things a bit. In fact I've noticed I feel better with that than over the counter stuff for the cold.
