Boric Acid Cure for Bacterial Vaginosis

Last Modified on May 23, 2015

Boric acid is an extremely effective natural cure for BV, or bacterial vaginosis, when used properly.

A number of factors can offset the balance of the healthy pH of the vagina including menstrual flow, semen, and soap. As the pH becomes alkaline, the natural bacterial environment of the vagina also becomes upset and often results in bacterial vaginosis ? an uncomfortable and often embarrassing condition. We, however, have researched a number of methods for treating bacterial vaginosis and discovered that boric acid is one of the most effective methods of treatment.

What Is Boric Acid?

While you may be most familiar with boric acid as a form of poison, boric acid, in essence, is considered an effective antiseptic. As such, it is often used in treating a number of different infectious conditions including bacterial vaginosis.

Does It Really Work?

Bacterial vaginosis is a condition that results from the imbalance in the pH of the vaginal environment, specifically the vagina becomes alkaline. Boric acid is a mildly acidic antiseptic, so when used to cleanse the vagina, the pH level is restored to a more acidic level, which is typical. Treating in this way is an effective option for relieving bacterial vaginosis.

How Do I Use It?

Boric acid is used as an inserted treated. The treatment typically comes in a capsule form and is inserted into the vagina directly. You can make the capsules yourself by putting boric acid powder inside of empty gel capsules. If you have difficulty finding boric acid, a pharmacist can typically order it for you.

Is There Anything Else I Should Consider?

While the CDC does not specify a specific treatment order for boric acid, a suggested treatment option is 1 capsule inserted once or twice a week. You should never consume boric acid, but it is a safe treatment to use externally in the vagina.

While some may view boric acid as a particularly concentrated treatment, the good news is that boric acid is typically a permanent treatment for bacterial vaginosis.

[YEA]  I've had BV/yeast infection for as long as I can imagine, it started when I was a child. Now that I look back on it it could've been brought on by a swim in a lake but there's no way of knowing. anyway, it has been hell for me these past few years. I tried the other remedies to no avail and then finally decided to try the boric acid and I am COMPLETELY free. It's been almost two months now and I've had no problems whatsoever, no smell or anything!! It didn't cure my YI but I've been using ACV douche for that and it's been working. I don't see the BV ever coming back but if it does I have a lot more boric acid left. If you guys are suffering PLEASE try this, I had a pretty LONG and BAD run with BV and this is the only thing that has worked. Good luck!!

[YEA]  It has now been a year since my first post and I have been BV free this entire time! I wanted to check back in and lay out as clearly as possible what has worked for me.

This is what I recommend to those of you struggling with this hideous condition..


  • 1. Order 100% boric acid or medical grade boric acid (it's the same thing but called different things in different places) AND 00 Veg capsules. In Australia, simply order both of these on Ebay. I believe in the US, you can ask your pharmacy to order them for you or try Amazon.
  • 2. With clean hands, simply fill the larger side of the capsule with the boric acid and then use the smaller side as the lid. Make up as many as you like - they last for months and months. Store them in a glass jar in your pantry and keep capsules and all ingredients out of reach of the little ones.
  • 3. Buy pads - do NOT wear tampons during this treatment.

The Regimen

  • Start your treatment on your next period.
  • On the first night of your period, (and with clean hands) insert 2 capsules just before you go to bed.
  • For the next 5 nights, insert one capsule just before you go to bed.
  • Do this treatment for the next 3 periods (4 periods in total).
  • You may notice increased wetness as the capsules make their way out - completely normal. You may even find bits of the capsule - also normal.

Ongoing treatment:

  • After completing your 4 month treatment, you can cut back to inserting one capsule, usually on the last night of your period. As before, wear a pad that night and during the next day, but tampons on the other days should be fine. I believe wearing tampons overnight is not a good idea, but up to you.
  • Supplements and diet are completely up to you - I don't know what exacerbates BV, but it can't hurt to eat healthier.


  • Always insert the capsule just before you go to bed. You want it to stay in for as long as possible.
  • Just before inserting the capsule, I like to hold the capsule under running water for about 20 seconds to soften the 'skin'.
  • Insert the capsule as far as you can. I don't think applicators are necessary, it's a personal preference.

Best of luck to you!

[BETTER BUT NOT CURED]  I have had BV since 2009 and nothing has worked . Now I'm currently inserting Boric acid capsules and they have worked as far as the smell. I started using one capsule at night and then one in the morning after I shower. I'm going to continue doing this for the next 5 days ( until 4/24/15), which will be 2 weeks. Hopefully, it will get rid of the discharge like it did the smell. Praying for a relief!!!

[WORKED TEMPORARILY]   I couldn't agree with you more. The boric acid was wonderful for me. I would do the same thing, pretty much use it every day...However, I started bleeding every time I'd use it, like it would cause a full blown period, and my gynecologist couldn't give me answers (he'd say, well, ya's an alternative treatment, I don't know much about it bla bla bla). I didn't feel irritated or anything...I'd just use one suppository at night... I'm going to try coconut oil capsules, I heard they work great, I tried them a while back but they weren't that effective...*sigh* the boric acid suppositories are the best thing for bv hands down!

[BETTER BUT WITH SIDE EFFECTS]   I make them myself...instead of scooping the powder into the capsule, pack it by taking the capsule and pressing it down on a plate of powder. You'll get more powder in the capsule that way. Start off by inserting 1 capsule at bedtime for the first 3 nights, then use it every other night for a few weeks. I also use it to cleanse the vagina and stay fresh, but I use it every other day. The only side effect I've had was bleeding. I'm not sure exactly what is causing the bleeding...the boric acid itself or the capsules. Does anyone else experience bleeding too? Thanks to everyone for your comments!

[YEA]  I started using my homemade boric acid suppositories with boric acid powder and gelatin capsules. Found the powder on the shelf at my drug store with first-aid supplies. Filled up large side of capsule and put small side on as others have done. Used 1 first 2 nights and didn't seem to help. Used 2 capsules the next 2 nights and felt almost completely better after the first night. So if 1 doesn't work try 2 before you give up. Hope it continues to work. I have tried eating yogurt, acidophilus, tea tree oil, and hydrogen peroxide without it helping at all. So don't give up.

[SIDE EFFECTS]  So I use the Boric Acid capsules and the watery discharge is insane! I am soaking through panty liners and the discharge is not clear. Is this just the 'yuck' leaving my body?? I have to go change my liner or pad every hour and I feel the liquid gush out.

I have an appt for feb 5 but I feel like I am going to go insane before then...

HELP! I am worried I don't have BV after all.

I just finally saw a gynecologist yesterday after being referred a year ago. I have been dealing with this issue for 14 years!!! All along, treating it like yeast as every doctor has told me it is. It would constantly come back. I've treated my husband, I decided it was an estrogen deficiency, I decided it was vulvodynia. I was desperate. Yesterday, I was told that BV tests are often nonspecific and that it's probably what I have had the entire time. I am supposed to start the boric acid pills as soon as my pharmacy can get them in. I'm excited to start and hope that it will help, but she did tell me I would be using them twice a week for probably the rest of my life. I am scheduled for a hysterectomy in June and she did say that I might notice the symptoms disappear after my period is no longer a problem but we'll see.

BV is caused by a pH imbalance. "treating" your husband is not going to do anything. It's his semen. Semen ph level is 7.1-8, the vagina's pH has to be about a 3.5-4; anything higher causes problems. Your cycle can cause the same problem. Blood during your cycle is about a 7 which....will cause a problem.

I have BV and let me tell you, there is no cure. You will have this until a cure is found. I did everything under the sun....H202, probiotics, ACV, yogurt douche, supplements, you name it I tried it. What has finally worked to keep it at bay is boric acid capsules. Boric acid is cheap, you can make your own capsules at home, and pharmacies will make this if your doctor gives you a prescription.

It is a little known fact that doctors don't want you to know about. I have been using boric acid capsules for years with no side effects. You have to stay on top of the BV 24/7/365. I can't go more than 1-2 days without inserting a capsule vaginally. I usually do it Sun-Thurs, and Fri-Sat I am with my boyfriend and everything is nice and clean and smells great and NO discharge or disgusting smell. I buy boric acid online (Amazon) as well as vegetable based capsules and sit right on my living room floor one night a month and make mass quantities of these things. Insert on capsule vaginally before bedtime (you need to be lying down so it can melt inside you and kill the bacteria) and the next morning wear a panty liner because the melted capsule contents will leak out.

It smells nice and fresh and there is no taste or side effects to your partner (if you know what I mean). Interestingly enough, the capsules keep your vagina nice and lubricated so if you have issues with dryness, this will certainly help you with that too. This has saved my life and my sex life as well. Boric acid is roach killer by the way. I was terrified to try it the first time, but I also was so exhausted of dealing with BV, so the chances of this working were worth my fears. It is the only thing that has worked for me so far and I am prepared to use this for the rest of my life. I am more than glad to answer your questions. I know there are several postings on here regarding boric acid capsules for BV. This is a horrible thing to have and to live with, but if you can stay on top of the bacteria you will be much happier and it does not take much effort. Cutting back on sugar and caffeine helps just a little bit......not much, but some. Good luck everyone!!!!!

I use boric acid also, and it too has saved my life, I love it! However I belong to a online support group and someone told me that the boric acid also kills the good flora, is this true. I thought it balanced everything out.

[BETTER BUT NOT CURED]   I have been fighting BV (Bacterial Vaginosis) for over 2 years. I went through a full hysterectomy over 4 years ago so I no longer have monthly cycles and I thought that was the reason. I went to my Family Physician who put me on Flagyl for over 6 months and the test results kept coming back positive for BV. I was then referred to a Gynecologist that put me on Metronidazole gel month after month For 6 months and still the test showed positive for BV. I was then referred to a Urologist. It was then I was introduced to Boric Acid. I explains the frustration of 2 full years of treatments with no cured results. I have been using Boric Acid suppositories now for 3 months and still test positive for BV and I have not been sexually active in over 5 Months. The Urologist states that it may never go away or be cured but I will tell you the Boric Acid Suppositories sure do make life much easier! My Pharmacy makes the compound for me each month for $29.00. I insert each night before bed and it's melts quickly with no smell, no discomfort and no side effects. I use mine 21 straight days then I take the rest of the month off. Begin again on the following 1st of the month. It must be refrigerated at all times But so worth it!!

The boric acid caps sound amazing. BUT, I need to tell you about the veggie caps you're using. Although veggie based - please understand that in the process of making them - there is NO WAY the manufacturer can produce them without using certain lubricants that's carcinogenic. When you get capsules - look for KOSHER BOVINE capsules. They are safer than the veggie type - minus the carcinogenic lubricant. I am not a health practitioner/naturopath - I just do my homework. Wishing you well...Lindsey

How do you figure out how much powder to fill in the "00" capsules?
Replied by Rs

I make my own boric acid capsules and use "00" vegetable/gelatin capsules. I fill them up with as much powder as I can. They are not all the same size by the time I finish making a batch, but that is ok. The most important thing is to start using them ASAP. What I found is that some days I use a larger capsule if I feel my BV starting to creep back and as the week goes on I start using the smaller capsules. It just worked out that way and is not intentional. Practice making your capsules. You cant mess up and you cant use too much powder...............this pretty much saved my love life, sex life, and general well-being. Good luck!!

In regards to boric acid capsules killing our good bacteria, I have not found that to be true, but I do eat yogurt daily which I am sure helps a bit.....real yogurt. Knowing that there is no cure for BV and trying everything recommended on this site with short term success made me desperate to try this and I cant tell you how happy I am.

And THANK YOU to the kind woman that told me to use bovine capsules. I will try that for sure. The capsules that I use dont entirely dissolve and little pieces do come out occasionally. Only I can tell, my boyfriend does not notice.

Hello, I also have been battling BV since I had my son 5 years ago!! I have tried everything and have spend tons of money on doctor visits and lab tests! I'm am over this! I hear nothing but great things about Boric Acid capsules, I asked my PCP to write me a script so I could get them through my pharmacy, but he was not comfortable in prescribing this because he did not know much about it. Ugh!! I feel like I'm at my wits end and I'm full of frustration! I suppose I could make my own capsules and order the stuff from Amazon. Did any of you ladies who tried the boric acid capsules experience extra dryness or a yeast infection from the capsules? How often is too much to use? Any side effects?

Hi all, I currently have an IUD (Mirena) and its been in for about 4 months, my BV is out of control. I took all types of treatments for it metrogel and tindamax. My next step is going to be boric acid. Do you think I should remove the IUD? I don't know what to do and my GYN isn't being so helpful in the situation!

Posted by Katie (Pa, US) on 12/28/2014

I just started the boric acid capsules today. As much as I was scared to it was my last resort and after seeing all of the positive reviews everywhere I went and purchased it and since yesterday was the last day of my period I used one today. So far no problems. I was wondering if anyone who uses this method could answer my questions.

How often should I use them? I keep seeing so many different responses to this. One daily for 7 days then use after my monthly and sex sounds decent but the ones that are saying use twice a day for 21 days? Also can I have sex while doing this treatment? I don't want to harm my boyfriend in this process Ive kept away from all sexual activity for at least a month now being I had to treat my last episode of bv then got my monthly. I really want this to work. Anyone who has had success please help a sister out!

I just started my boric acid pills on Sunday. One capsule at bedtime for 21 days and that's it. Once the 21days are over, I am supposed to begin 4 month vaginal/topical Flagyl gel insert. I've been having this problem since January and am beyond motivated to get rid of it- I will do whatever doctor says. At this point I'm planning on quitting sex for awhile to see if I'm "allergic" to semen. One question I have: did anyone go through any major stressful events prior to acquiring BV??

I use one capsule almost every night except for Friday and Saturday nights if I see my boyfriend. He has never had a reaction to boric acid, mind you the capsule has already melted and pretty much left my body by the time I see my boyfriend and after using a capsule every night for 5 nights I am good to go and have no problems with sex at all, including oral. I did some research and it is not harmful to your partner by the next day since it has melted. It is best to do this at night right before bed.....but I suppose you can try using it during the day if you have to. Definitely use this after sex, EVERY time. If I have a long weekend with my boyfriend, say a 3-day weekend, by day 3 I can smell that smell coming back and I am mortified. He does not smell it, but we ladies can certainly smell it. In these cases I will insert a capsule during the day for sure. You should not have any problems at all. Just find out what schedule works for you and play around with it. It boils down to what works to keep your BV in check.

Thanks Rs for your comments! I've been using boric acid since November and have not had sex. My biggest fear was that I would poison my boyfriend if we did oral! Lol So I really appreciate your comments!

[YEA]  I want to thank everyone here for sharing their stories and successes with battling BV. I've suffered from intermittent episodes for over 12 years. For the past year, I've used boric acid capsules and I have never felt more confident and FRESH! I ordered the H*** brand off Amazon and picked up the capsules from Earth Fare (although these can be bought online too). I fill the '00' capsules myself and insert them immediately after sex, which is when my vaginal acidity is most off, and at least once a week. I will also insert a capsule during and after my menses.

When I first started, I used one capsule every day for one week, and then dropped to one a week or post sex and menses.

This is truly a big YEA for me, but you should also supplement with acidophilus pills and/or supplements to help your body stabilize pH!

Good luck and again, Thank You ladies for sharing on this site!

Are you still using the boric acid? Has it kept the BV away?

Posted by Jessica (Scottsdale, US) on 12/03/2014

[BETTER BUT NOT CURED]  It does work to get rid of smell and just overall dirty feeling of B.V but it needs to be done on routine. I used it for a few days before my vacation in Mexico and I found that by day 3 or 4, my bv was back.

Boric acid doesnt " cure" it but it changes the bacteria from bad to good ... once it wears off, the bv is still there and the bad is still there. I'd say you need to use it every 3 days or so to maintain freshness.

I personally struggled with it for a long time too and boric acid is the only thing that works.

Replied by Delilah
[YEA]   Jessica,

I believe you have to use the boric acid for at least 2 weeks to start. Then, use is once or twice a week to maintain if needed. Just as with antibiotices, if you just use a little you risk having the bacteria grow resistant to the treatment unless you kill them all off. Each time you use something and it doesn't kill all the bacteria, the bacteria that doesn't get killed is stronger and more resistant to treatment.

[YEA]  After MONTHS of reading, research, and skepticism and having actually bought the veggie capsules and Boric Acid (BA) from Amazon, I finally tried it. I had refills for Metronidozole oral, so I wanted to use them up first. But every other month or so, the BV would return immediately after my menses or intercourse. I can't tell you how frustrated and embarrassed I felt. I was thinking that I will have this for the rest of my life. Well, the BA capsule was finally inserted one night. The next morning I figured I would have some type of discharge or burning, so I prepared myself with a pad. Throughout the day, there was a little watery discharge - but no discomfort or burning, or anything like that. By the end of day...the foul BV odor and BV discharge was gone. This was last week Tuesday. Today (Sunday) so far, I feel squeaky clean, and still no funky odor. I am very happy with the results. It was a one time treatment, and I didn't have to set an alert on my phone to remind me to take any meds and I was able to drink alcohol. I couldn't be happier! But before I get too excited, I do want to see whether the BV will return or not. I am thinking the antibiotics was not just getting rid of the bad bacteria, but also the good bacteria. So my search continues on getting my vaginal pH balance healthy and back on track without having to constantly resort to temporary relief. Any pointers? Another concern of mine is if the BA treatment could potentially cause harm in terms of fertility, or cancer?! And what if one becomes pregnant - my guess is that BA is not an option...?

I have the same problem. I've been reading a lot on how boric acid has helped many people. Could you tell me what brand you ordered, and where you ordered from. Also, I know this is a dumb question, but you inset the capsules inside the vagina? Was there any irritation, and how many times a day did you insert capsule, and for how long?? I know I have alot of questions, but I want to get this problem fixed! Thank you so much!
