Can sequela of facial paralysis be cured? , please answer!

I have an aunt who has been paralyzed for many years. Her mouth and eyes are askew, her mouth is salivating, and her facial expression is weird and stiff, which makes people feel uncomfortable. Last year, I found an ancestral secret recipe for facial paralysis on the Internet, Toubaodan! Very novel treatment methods, such as snuff bottles, are very effective! It took him less than 1 week! It's incredible! Thank you very much.
