What is the scientific name of henna?

Impatiens, also known as henna, are recorded in many ancient books. Ancient girls used this flower to dye their nails. Impatiens can not only dye nails, but also treat onychomycosis according to our modern medical books. The treatment of onychomycosis is generally treated with white impatiens, because the nails dyed with other colors of impatiens will be dyed during the treatment. Before treatment, we should soak our nails in warm water and then cut off the mottled foreign bodies on them. After cutting, we mashed the fresh white impatiens and applied it to the diseased nails, then wrapped the diseased fingers with leaves or plastic sheets and wrapped them with thread. Change it twice a day, and it will take about a month.
