4. Nettle Tea
Moving away from oils for a moment, nettle tea is an interesting option that can help you to fight a cold. That’s because it is a natural anti-histamine, which means it will block one of the hormones that triggers the allergic reaction in the first place.
Do keep in mind that histamine is a natural excitatory neurotransmitter. That means that it plays an important role in increasing activity in the brain and anything you do to reduce it is going to cause a little drowsiness and grogginess.
It’s not just the OTC medications that are responsible for this!
