Kudzu is medicinal. I grow medicinal herbs in my farm and so I get to ‘hear in’ what herbalists discuss amongst themselves.

Kudzu in combination with other herbs was considered for covid during early times. I subscribe to homeopathy myself rather than herbalism and found Byronia Alba a close substitute. Altho I use it as a prophylactic. (Not medical advice. It’s just for my own constitution and supports my constitutional remedy. Not falsifiable)
