Nature gives us everything to protect us

And at the right time.


For example it gives us fruits from citrus trees to protect us from caching a cold or doing way with it.


It can be seen that the first ripe fruit in a tree is ready the first day of feeling cold after autumn. For example a bitter orange. They are full of vitamin C which seems to be the source of energy for our immunity system.


In fact every fruit around the year should serve a specific purpose.
