Some poorer /smaller countries like Slovakia/Czechia
Thailand pop =60 million used Sinovac .. but there wasn't much around and they have low bargaining power with Pfizer ..
so they approved andrographis paniculata..or king of bitters, a plant remedy..
seems to have immunomodulatory effects..
My friend Don has a bottle made in Australia just in case..he gets Covid
He said the Thai government really had no choice at the time..
no good for prevention...since prolonged usage can harm the liver..
A promising development in the fight against Covid
After five days of treatment, more than 300 Covid-19 patients have been cured by fah talai jone (andrographis paniculata) or green chireta.
