Is Boric Acid Good for Your Vagina?

How does boric acid help treat vaginal infections?

Boric acid has antibacterial and antifungal properties and contains probiotics and vitamins C and E. As such, it helps restore normal vaginal acidity and vaginal flora balance and can be used to treat vaginal yeast infection symptoms such as burning, itching and odor. 

According to several studies, boric acid was effective in eradicating yeast infections in 40%-100% of cases. Treatment is thought to be relatively safe, with only minor, temporary side effects. It is also a less expensive option than more traditional treatments. 

Studies have also shown that boric acid can effectively suppress the growth of Trichomonas, another fairly common vaginal infection. If your trichomoniasis infection hasn’t responded to traditional treatment, boric acid treatment may be considered after discussing it with your doctor.

While there is not enough clinical evidence to support the claim that boric acid is effective in treating bacterial vaginosis, boric acid can restore the natural pH and flora of the vagina, and therefore help keep the vagina healthy.

What are common vaginal infections?

The two most common vaginal infections include:

Vaginal yeast infection

A fungal infection of the vaginal entrance and surrounding tissues caused by Candida. Antibiotics and pregnancy can disrupt the balance of bacteria in the vaginal canal, allowing yeast to flourish. Yeast thrives in the vagina, as it provides a moist and warm environment to grow. Signs and symptoms of vaginal candidiasis include:

• Intense itching in and around the vaginal area
• Swelling, burning, and redness
• Pain when urinating and having sex
• Soreness in the genital area
• Thick, white discharge that has a cottony texture but a normal odor

Bacterial vaginosis (BV)

During the reproductive years, BV is the most common cause of vaginal infection and discharge. When there is more harmful bacteria than healthy bacteria in the vaginal area, it leads to an imbalance in the flora. BV arises when Lactobacillus bacteria, which are present normally in the vaginal canal, are disrupted by an overgrowth of other harmful bacteria. Although there is no definitive cause, there are a few contributing factors such as having multiple sexual partners, using an intrauterine device, and not practicing safe sex. Signs and symptoms may include

• Fishy smell from the vaginal area
• White or grey vaginal discharge (might be watery or frothy in texture)
• Itching and/or discomfort in the vaginal area
• Burning sensation when urinating
