Uterine fibroids are benign (non-cancerous) tumours that develop within the muscular wall of the uterus. They are composed of smooth muscle and connective tissue and are typically round and firm in texture. Fibroids can range in size from very small—sometimes no larger than a pea—to much larger growths, occasionally comparable to a hen’s egg or more. Their size may also fluctuate throughout the menstrual cycle.

From a naturopathic perspective, uterine fibroids are commonly associated with hormonal imbalance, particularly oestrogen dominance—a state where oestrogen levels are high relative to progesterone. This imbalance may also indicate that the liver is under strain and not efficiently metabolising and clearing excess oestrogen from the body.

Fibroids generally grow slowly over many years, and their growth is influenced by the total amount of oestrogen the body is exposed to over time.

Common Symptoms of Uterine Fibroids

Symptoms vary depending on the size, number, and location of fibroids, and may include:

Prolonged or heavy menstrual bleeding
Painful periods, cramps, or spasms
A feeling of fullness or pressure in the abdomen
Enlargement of the lower abdomen
Pain during sexual intercourse
Frequent urination due to pressure on the bladder
Bowel discomfort or pain

Some women may have fibroids with minimal symptoms, while others experience significant disruption to daily life.

Causes of fibroids

Uterine fibroids develop as a result of multiple interacting factors rather than a single cause. From a naturopathic perspective, the most significant driver is hormonal imbalance, particularly oestrogen dominance, where oestrogen levels are high relative to progesterone. This imbalance may be influenced by increased lifetime exposure to oestrogen, poor liver clearance of hormones, excess body fat (which produces oestrogen), and exposure to environmental or synthetic oestrogens. Fibroid growth is also affected by insulin resistance, chronic inflammation, and impaired detoxification pathways. Genetic susceptibility, nutritional deficiencies, and long-term stress—through its effects on adrenal and thyroid function—may further contribute. Together, these factors create an internal environment that supports slow, progressive tissue overgrowth within the uterine muscle.

Hormonal Balance and the Role of Vitex Agnus Castus

Vitex Agnus Castus (Chaste Tree)

Vitex Agnus Castus is a traditional herbal medicine widely used to support female reproductive and hormonal health. Rather than supplying hormones directly, Vitex works by influencing the communication between the brain and the ovaries, helping to regulate the menstrual cycle.

In naturopathic and traditional medicine systems, menstrual and reproductive issues are often linked to disturbances in the flow of blood and energy (Qi). Vitex is traditionally used to support cycle regularity, reduce heavy bleeding, and ease premenstrual symptoms.

Vitex is particularly valued for its ability to:

Support healthy progesterone levels in the luteal phase
Improve the oestrogen–progesterone ratio
Reduce symptoms of premenstrual tension such as anxiety, low mood, and breast tenderness

⚠️ Vitex is not recommended for individuals using the oral contraceptive pill or certain hormone-based medications unless supervised by a healthcare professional.

Diet Tips for Supporting Fibroids

Nutrition plays a central role in hormonal balance and liver detoxification.

Foods to Emphasise

“Alive” and growing foods such as wheatgrass, barley grass, spirulina, sprouts, soaked grains, and seeds
Plenty of fresh vegetables, especially green leafy vegetables
Antioxidant-rich foods such as berries, grapes, and green tea
Whole grains like millet, brown rice, and buckwheat
Oily fish for anti-inflammatory support (if included in the diet)

Foods to Reduce

Processed and preserved foods
Refined sugar
Alcohol, tea, and coffee
Foods that may contribute to lymphatic congestion such as excessive dairy and refined wheat

Some naturopathic approaches recommend a low-fat, whole-food, mostly plant-based diet to reduce excess oestrogen load and support alkalinity.

Hydration and Liver Support

Increase water intake through filtered water and herbal teas
Use vegetable juices (rather than fruit juices) to support lymphatic flow and liver detoxification
Adequate hydration assists hormone clearance and reduces congestion

Lifestyle Factors That Influence Fibroids

Acupuncture: May help improve pelvic circulation and reduce stagnation
Liver support programs: Can assist with hormone metabolism and clearance
Weight management: Excess body fat increases oestrogen production
Avoid alcohol: Alcohol reduces the liver’s ability to metabolise oestrogen
Limit synthetic oestrogens: Including hormonal contraceptives, where appropriate
Regular exercise: Improves circulation, lymphatic flow, insulin sensitivity, mood, and hormone balance

Topical and traditional supports may include:

Clary sage essential oil (topical use with guidance) for pelvic discomfort
Ginger poultices applied to the lower abdomen to reduce congestion and pain

Natural and Herbal Support

Under professional guidance, herbs commonly used to support fibroids and ovarian health may include:

Vitex Agnus Castus: Hormonal regulation
Paeony: Traditionally used for menstrual pain and blood flow
False Unicorn Root: Reproductive system support
Bupleurum: Liver and hormonal support
Milk Thistle: Liver detoxification and protection
Evening Primrose Oil: Supports inflammation and hormone balance

Nutritional Support

Vitamin C and bioflavonoids: Antioxidant and tissue support
Fish oil: Potent natural anti-inflammatory
B vitamins: Support hormone metabolism, adrenal balance, and menstrual regulation
Chromium: May be helpful where blood sugar imbalance or ovarian cysts are present

Uterine fibroids are common and often reflect long-standing hormonal and metabolic patterns rather than a sudden issue. A naturopathic approach focuses on addressing underlying causes, particularly oestrogen dominance, liver function, inflammation, and lifestyle factors, while supporting the body’s natural ability to rebalance over time.
