Hi. I haven't heard of any of the other mentioned attempts to cure but what worked for me, as recommended to many people during COVID-19 2020 is to inhale strong + pure essential oils in each nostril separately at regular intervals. Peppermint, orange, lavender, spearmint, etc. The process behind this is that the cranial nerves crease to function properly from the virus. Stimulating these nerves to wake them up and coordinate and transmit signal again is the intended outcome. This approach worked for me.
Incredibly better news his just been published that breathing essential oils for only 2 hours while sleeping (thru a diffuser) increases memory dramatically. This is a medically published study result. I forwarded it to my Dr and she responded she loved it.
Wishing you the best.
