Don't confuse henna with henna root (Alkanna tinctoria), also referred to as alkanna root.
Historically, henna has been used for severe diarrhea caused by a parasite (amoebic dysentery), cancer, enlarged spleen, headache, jaundice, and skin conditions. These days, people take henna for stomach and intestinal ulcers.
Henna is sometimes applied directly to the affected area for dandruff, eczema, scabies, fungal infections, and wounds.
In manufacturing, henna is used in cosmetics, hair dyes, and hair care products; and as a dye for nails, hands, and clothing.
People also use henna on the skin as temporary "tattoos."
