@literally45-- I agree that tea tree suppositories are great for yeast infections. I personally have treated mine with it, along with probiotic yogurt. The suppositories do burn for like the first ten seconds but the feeling goes away after that. It hasn't been a big deal for me but I understand that others might be more sensitive about it.
My sister in law also uses tea tree suppositories sometimes, not for yeast infections but for interstitial cystitis. She says it relieves her symptoms somewhat.
