FAQ #13: How do naturopathic doctors help prevent and treat cervical dysplasia and Human Papillomavirus (HPV)?

Cervical dysplasia refers to pre-cancerous changes in the cells on the surface of the cervix. While dysplasia can be caused by a number of factors, one common cause is the presence of one of the strains of Human Papilloma Virus, or HPV. Often times, the body will heal an HPV infection on its own and cervical cells go back to normal as the infection clears. In some cases, however, the grade of cervical dysplasia can worsen. Without treatment, advanced cervical dysplasia can progress to cervical cancer. In the U.S., Pap Smears have cut the incidence of cervical cancer in half over the past 40 years due to early detection. But approximately 40 percent of American women (and 45 percent of men) currently have some form of HPV, putting them at risk.

Naturopathic doctors who specialize in women’s health offer you and your sexual partner both preventive education and natural treatments for dysplasia and HPV. Naturopathic doctors focus on the least invasive, most natural, effective treatments first, and partner with conventionally trained specialists if surgical interventions are needed.

Risk Factors

The main risk factor for cervical dysplasia is the presence of HPV. Other risk factors include:

  • Multiple sexual partners
  • Young age at first intercourse (<16)
  • Intercourse with uncircumcised partner
  • Unprotected intercourse
  • Chlamydia and HIV
  • Compromised immune system
  • Smoking
  • Nutritional deficiencies
  • Diethylstilbestrol (DES) exposure
  • Long term oral contraceptive use (>5 years)
  • Low socioeconomic status

Screenings and Prevention

Naturopathic doctors follow the American College of Obstetricians and Gynecologists (ACOG) guidelines for dysplasia and HPV screenings in women 21-65 years old, utilizing the Pap Smear and HPV tests. Additionally, naturopathic doctors recommend and perform screenings for HPV and dysplasia in the mouth, throat, and anus, where the virus can also be spread through contact with sexual partners.2,3 Patients who have an abnormal result or test positive for HPV are advised to have their sexual partners also be tested and treated, to prevent further transmission.

Naturopathic doctors emphasize these important preventive measures:

  • Practicing safe sex. Safe sex decreases transmission of HPV, HIV, and other sexually transmitted diseases.
  • Smoking cessation. Smoking is linked to cervical cancer as it increases the duration of infection with high risk HPV.4 Smoking also weakens the immune system.
  • Optimizing nutrition. Poor nutritional status is linked to cervical cancer. Folate and B12 deficiencies have been associated with increased HPV infection.5 Low serum retinol levels have been linked to increased risk of dysplasia.6 Naturopathic doctors have advanced training in nutrition and will provide a comprehensive nutritional intake and individualized dietary counseling to address nutritional deficiencies.

HPV vaccination can reduce the risk of infection by the HPV types targeted by the vaccine. Because none of the currently available HPV vaccines protect against all HPV infections, it is important for vaccinated women to continue to undergo cervical cancer screening.


If you are diagnosed with cervical dysplasia and/or HPV after your Pap Smear and HPV test, your naturopathic doctor may refer you for a colposcopy, a procedure which uses a special magnifying instrument (colposcope) to determine the extent and degree of dysplasia. Dysplasia is then categorized as cervical intraepithelial neoplasia (CIN), and graded level I (lower grade change in cervical cells), II, or III (highest grade change).


Depending on your diagnosis, conventionally trained doctors often suggest one or more of four treatment approaches for dysplasia: 1) “watch and wait” and repeat the Pap Smear every 3 to 6 months, 2) cryoptherapy to freeze abnormal cells, 3) loop electrosurgical excision procedure (LEEP), which uses electricity to remove affected tissue, and/or 4) cone biopsy, to remove the affected portion of the cervix. Risks and complications of surgical procedures can include scar tissue, prolonged bleeding, and infection. These complications can have longer term effects on conception and childbirth.7 Additionally, these treatments may not address the underlying cause of the cervical dysplasia, which is the HPV infection.

Naturopathic doctors offer natural therapies to treat dysplasia and HPV directly, and to help the body’s immune system fight the virus. In doing so, naturopathic doctors may reverse low-grade cervical cell abnormality and eliminate HPV. Naturopathic doctors treat low- and mid-grade dysplasia with a combination of lifestyle modification, therapeutic diets, nutrient and botanical therapies, and local treatment of the cervix. Specific therapies are individualized to the patient based on their diagnosis, emotional, and physical constitution. Nutrient and botanical therapies may include:

  • Folic acid8
  • Indole-3-carbinol9,10
  • Antioxidants11,12
  • Vitamin C13,14
  • Green tea extract15
  • Coriolus versicolor16
  • Curcumin17
  • Methyl B1218

Local cervical treatments may include:

  • Vaginal suppositories consisting of green tea and/or curcumin, which draw infection out of the cervical cells and boost the immune system.19,20
  • Escharotic treatment, which uses natural enzymes and herbal solutions to remove abnormal, damaged tissue and stimulate the regrowth of normal tissue. This treatment is performed two times per week for approximately six weeks.21,22

Thousands of patients have safely benefited from this treatment, but larger clinical studies are needed.

It is important to have a comprehensive diagnosis and consider all of your options for managing cervical health. There are times natural medicine is not an option for treating cervical cell changes due to the severity and location of disease. In many cases, however, naturopathic treatment of cervical dysplasia and HPV is a safe and effective option.

Bruce Barlean

Bruce Barlean is an owner and founder of Barlean’s, a global dietary supplement manufacturer located in the Pacific Northwest in Ferndale, WA. Bruce has been actively involved in the Natural Products industry since 1989 and is passionate about making a difference in the world and positively impacting the lives of others.

Bruce believes that people can make a difference in the world through ordinary purchases. He is committed to improving the quality of life for every person on the planet by making the best products and by using the profits to support outreach programs. Bruce summarizes it simply, “We make good stuff to do good stuff”.

In the late 1980’s Bruce became passionate about how health could be dramatically improved with Flax Oil Supplementation. Bruce along with his entrepreneurial parents saw the potential to improve the lives of many people and in 1989 they began selling Flax Oil under the Barlean’s name. From 1989 – 2000 the business grew an average of 40% year over year. While most companies saw a decline in business in the 2001 recession, Barlean’s continued to grow and soon became America’s #1 selling flaxseed oil and continues to be to the present. The brand has since expanded to include additional oils, green food concentrates and other premium supplements. Bruce continues to drive innovation and over the years his products and company have won countless awards including: Eight consecutive Vity Awards for #1 EFA, Six consecutive Vity Awards for #1 Greens Food Supplement, Natural Choice Award for Best Specialty Supplement, Best Product of the Year, Best New Product, Gold Medal Taster’s Choice Award, Gold Medal American Masters of Taste Award, #1 Health Food Store Brand for Consumer Satisfaction by Consumer Lab, and Manufacturer of the Year.

In 2013 as the company was on the eve of celebrating the 25th year in business Bruce and his parents decided to take their desire to help people to a new level that they call Pathway to a Better Life – which is now seen in the Barlean’s logo. Bruce and his parents had always been generous in their giving and support of charities, but as part of the Pathway to a Better Life they decided to increased partnership with charitable organizations such as: Vitamin Angels, Compassion International, KidsTown International, Autism Hope Alliance, Engedi Refuge, Project 92, and others. And because so many people are unable to meet basic nutritional needs, Bruce created a comprehensive Omega-3 and multivitamin formula that he distributes free-of-charge to local food banks. In addition, Bruce decided the company would supply food banks with organic coconut oil to provide people with a health alternative to standard cooking oils.

Always generous with his time Bruce has served as a youth leader for his local church for several years and continues to mentor youth. He has been on several not for profit boards including; Whatcom County Pregnancy Center (2003-2006), Natural Products Association (dates?), and the Institute for Natural Medicine Leadership Council (presently).

The Barlean family have been avid supporters of Bastyr University since the 1990’s and in 2013 were given Bastyr’s most prestigious honor, the Mission Award, which recognizes their leadership over time in improving the health and well-being of the human community.

Bruce currently resides in Ferndale, WA with his wife Lisa and their two dogs: Heinz & Shadow. When he’s not helping others he can be found fishing (catch & release).
