I would say I am down with the premise, but I promise our ancestors were using some equivalent of a neti pot. Steam was used for lots of ailments. Probably a better answer than anti-histamines.

Im thinking about our hairy ancestor cavemen. And I think steam makes sense as a solution but you still have to blow your nose. It also wasn’t regularly available especially during the winter when you were most likely to get sick.
Can’t say I am well read on the topic, but maybe they were using leaves or plants? Who knows? We were using handkerchiefs within the last 50 years, so, 🤷🏻
In Africa we use eucalyptus leaves, we boil them with water and after it has been boiled to the point it releases that nice eucalyptus aroma, you cover your body and the pan with a blanket, slowly inhale and exhale the steam for at least 45 minutes. It saved my life during Covid infection. Your skin and lungs will literaly release all toxins through pores and mucus, because of the steam.
