Ginger is one of the most widely used and beloved ingredients in kitchens around the world. Its unmistakable zing adds freshness and complexity to everything—from teas and smoothies to desserts, soups, stir-fries, and meat or vegetable dishes. (Updated Aug 16, 2024)

Yet ginger is far more than a flavorful spice. For more than 2,000 years, traditional healers across Asia and the Middle East have relied on this vibrant root for its antiviral, antibacterial, anti-parasitic, and antioxidant abilities. Modern research now confirms that ginger contains over 40 potent pharmacological compounds, each contributing to its impressive therapeutic power. (1)

One of the most exciting modern discoveries is ginger’s potential anti-cancer activity. Studies have found that certain compounds in ginger may target cancer stem cells, help prevent new tumor formation, and support the survival of healthy cells—something conventional chemotherapy is often unable to do.

Ginger’s Anti-Cancer Compounds

The part of the ginger plant most commonly used is the rhizome, a firm, aromatic underground stem similar in appearance to a carrot. This rhizome is packed with essential nutrients, including calcium, iron, magnesium, manganese, phosphorus, potassium, sodium, and zinc. It also carries a broad spectrum of vitamins such as B1, B2, B3, B5, B6, folate, vitamin C, and vitamin E.

Perhaps even more valuable are ginger’s powerful antioxidant compounds—gingerols, shogaols, zingerones, and paradols. These bioactive molecules are believed to be responsible for many of ginger’s health benefits, including its anti-inflammatory and anti-cancer properties.

Research Findings on Cancer Prevention and Treatment

Numerous studies indicate that ginger may act as both a cancer-preventive agent and a therapeutic compound. A 2012 study published in the British Journal of Nutrition found that whole ginger extract (GE) significantly inhibited the growth of a variety of prostate cancer cells—reducing cell proliferation by up to 56%. (3,4)

Other studies suggest that ginger may help combat some of the most aggressive and difficult-to-treat cancers, including:

• Skin cancer (5)

• Lung cancer (6,7)

• Ovarian cancer (8)

• Colon cancer (9)

• Breast cancer (10,11)

• Pancreatic cancer (12)

Ginger and Ovarian Cancer

Ovarian cancer is especially dangerous because symptoms often appear only after the disease has progressed. More than 75% of women with ovarian cancer are diagnosed at an advanced stage. (13)

In a 2007 study published in BMC Complementary and Alternative Medicine, ginger not only inhibited ovarian cancer cell growth but also regulated the secretion of angiogenic factors—the substances cancer cells use to encourage nearby tissues to form new blood vessels. These new vessels supply tumors with oxygen and nutrients, allowing them to grow and spread (a process known as metastasis). (14)

By disrupting this process, ginger may help slow or block tumor development.

Ginger and Colon Cancer Prevention

Chronic inflammation in the colon increases the risk of developing colorectal cancer. One study found that individuals who took ginger supplements experienced a 28% reduction in colon inflammation markers. (15) This suggests that ginger may play a protective role when incorporated into a daily wellness routine.

Why Ginger Is So Effective Against Difficult Cancers

Cancer stem cells make up less than 0.2–1% of a tumor, yet they are incredibly resilient. These cells can regenerate and spread, making them responsible for recurrence and metastasis. Ginger appears to target these stem cells directly—addressing cancer at its root source.

Research also shows that ginger may help reduce the toxicity of certain substances, including chemotherapy drugs. While chemotherapy can cause cancer cells to become drug-resistant over time, a study from the University of Michigan showed that cancer cells did not develop resistance when exposed to ginger. (16)

For this reason, some researchers believe ginger could be a valuable complementary therapy alongside conventional treatments.

Forms of Ginger and How to Use Them

Ginger is available in many forms, each suitable for different purposes:

1. Fresh Ginger Root

Found in nearly all grocery stores, fresh ginger can be used immediately or frozen. When frozen, simply grate or slice off what you need. Fresh ginger is excellent for cooking, juicing, or making tea.

2. Crystallized Ginger

Often used as a snack or digestive aid, crystallized ginger is helpful for nausea, indigestion, or motion sickness.

3. Ginger Syrups

These are commonly sold in health food stores and are soothing for colds, flu, or respiratory issues.

4. Herbal Extracts (Tinctures)

Extracts may be water-based or alcohol-based. While both can be effective, studies suggest that alcohol-based ginger extracts may deliver stronger therapeutic benefits.

5. Ginger Supplements

Capsules or powders offer a convenient way to take ginger daily. As with any supplement, choose a reputable brand with high-quality sourcing and standardized potency.

6. Ginger Tea

You can buy a commercial tea or make your own. To prepare homemade ginger tea:

1. Cut about a 1-inch piece of fresh ginger.

2. Slice or grate it.

3. Boil it in 1½ cups of water for 10 minutes.

4. Add honey or stevia to taste.

This soothing tea is excellent for digestion, immunity, and overall wellness.

Important Safety Notes

While ginger is safe for most people, there are a few important guidelines:

• Do not exceed 4 grams of ginger per day from all sources combined.

• Ginger is a natural blood thinner, so if you take anticoagulant medications, consult a healthcare professional before using ginger regularly.

• Individuals with gallstones or certain digestive issues should also check with a medical provider before using large amounts.
