prodructs you can try that are cheap and may help treat BV.
Douching with Hydrogen Peroxide once a day if you want to keep the discharge and smell at bay. cost=$1.00-$2.50.USD 32.oz bottle. Use one 4 oz. bottle and fill it half way with the hydro and the rest with distilled water or water that has been boiled.
Vitamins! a multivitamin plus extra folic acid and vitamin B complexes are good places to start. cost= multivitamins$8.00-$10.00, Vitamin B complexes start as low as $6.00+, Folic acid $4.00-10.00, depends on mgs.
Drink Garlic Tea! Garlic Cloves sell in a bundle from $1.00-2.50. crush those bad boys up and stir it into hot water and drink. It doesn't taste that bad compared to other things I've tried lol.
And Eat lots and lots of yogurt! The best brands with the most probiotics is Chobani and Kefir. Kefir is a bit pricey but is worth not only drinking but inserting into the vagina as well. It will help with inflammation and discharge.
These are some things you can try and buy that won't break your wallet. If you'd like to try other things that might be a bit more expensive please email me or ask and I'll be happy to share.
