Yes Asians have lots of such hacks based on wisdom of ancient ppl. Many work too. My only concern is ppl don't take precautions like masks etc after following such hacks. In Pakistan ppl started taking a Herb based on Prophet Hadith which has nothing to do with this covid-19. Some one recommend and everyone started following as a religious obligatory. Many suffered from dirrehea . My friend died due to one of these hacks. He took no mask, got severe congestion and died.
