it stains lips pinkish red

rural women with little access to cosmetics use it …as then they don’t need lipstick for 2-3 days

Dr Catherine its proved antimicrobial herb. Dried bark is used as brush to clean teeth. Quite effective.  it doesn’t stain teeth. But when you use it  mucosal skin stains..not much research has been done on it except antimicrobial activity..couldn’t find many publication but its a wool colorant in presence of alum.. can be pH related  just guessing…

Thanks for answering Perry. In rural parts of asia it is widely used as teeth cleaner  and lip stainer by women. PubMed published papers to prove its anti microbial properties and hair coloring ( that disapproves its use). Used in wool industry to color wool brown in presence of alum. so just wondered . Thanks for clearing my doubts
