Last time the baby's toe was bitten by a mosquito, the whole toe was swollen and rough. Finally, a famous family of Chinese medicine practitioners here opened a kind of snake pill (I forgot the specific name, so I just looked around and couldn't find the rest. I don't know where it was thrown to the baby, but it is a black pill for oral and external use to treat the bite of poisonous snakes and insects. After grinding the pill into powder, it is mixed with calamine solution (it seems to be used again). I wonder if it belongs to mirabilite. Anyway, most pharmacies have a white liquid with precipitation, which is very cheap (2, one bottle in 3 yuan). Shake well, pour some out and mix with the powder just now. Should be effective. My baby wiped it twice and disappeared. It's best to go to the hospital or get some medicine for internal and external application. Don't be careless on your face.
