This is not mentioned here on this site but with respect to labia issues, I wanted to put in my 2 cents worth.
Labia itching, extreme/intense, at the pubic line has plagued me for several years. Recently, I itched while sleeping so bad I caused an ulcer to develop. VERY painful.
The cream my skin doc. had prescribed was not helping with the itching this time. I grabbed a jar of Calcium Bentonite Clay that was handy on my bathroom sink and applied the powder all around. The itching stopped immediately. No pain except the ulcer from patting the powder on it.
It's been 5 days, applying the powder once a day in the am, the ulcer is healing and there is zero itching.
Relief! Hope this helps someone.
