From Arthritis to Pain Relief: 5 Benefits of Ginger

By Dipa Kamdar

From warming winter teas to zesty stir-fries, ginger (Zingiber officinale) has long been a kitchen staple. But beyond its culinary charm, this spicy root has a rich history in traditional medicine – and modern science is catching up. Studies now show that ginger may offer a wide range of health benefits, from easing nausea and relieving colds to reducing inflammation and supporting heart health.

Here’s what you need to know:

1. Nausea Relief

Multiple clinical trials have shown consistent evidence that ginger can reduce nausea and vomiting, particularly when compared to a placebo. The NHS even recommends ginger-containing foods or teas for easing nausea.

Ginger seems especially effective for nausea during pregnancy. In small doses, it’s considered a safe and effective option for people who don’t respond well to standard anti-nausea treatments.

There’s also promising evidence that ginger can help with chemotherapy-induced nausea, though results are mixed when it comes to motion sickness and post-surgery nausea.

Researchers believe ginger’s anti-nausea effects may work by blocking serotonin receptors and acting on both the gut and brain. It may also help by reducing gas and bloating in the digestive tract.

2. Anti-Inflammatory Benefits

Ginger is rich in bioactive compounds, such as gingerol and shogaol, which have strong antioxidant and anti-inflammatory properties.

Recent research suggests ginger supplements may help regulate inflammation, especially in autoimmune conditions. One study found that ginger reduced the activity of neutrophils — white blood cells that often become overactive in diseases like lupus, rheumatoid arthritis and antiphospholipid syndrome.

Neutrophils produce extracellular traps (NETs), which are web-like structures used to trap and kill pathogens. But when NETs form excessively, they can fuel autoimmune diseases. In the study, taking ginger daily for one week significantly reduced NET formation.

While this study used ginger supplements, it’s unclear whether fresh ginger or tea has the same effect. Still, the findings suggest ginger may be a helpful, natural option for people with certain autoimmune conditions – though more research is needed.

Ginger also has antimicrobial properties, meaning it can help combat bacteria, viruses and other harmful microbes. Combined with its anti-inflammatory effects, this makes ginger a popular remedy for easing cold and flu symptoms like sore throats.

3. Pain Management

When it comes to pain, the research on ginger is encouraging – though not conclusive. Some studies show that ginger extract can reduce knee pain and stiffness in people with osteoarthritis, especially during the early stages of treatment. However, results vary, and not everyone experiences the same level of relief.

For muscle pain, one study found that taking two grams of ginger daily for 11 days reduced soreness after exercise.

Ginger may also ease menstrual pain. In fact, some studies suggest its effectiveness rivals that of non-steroidal anti-inflammatory drugs like ibuprofen.

Researchers believe ginger works by activating pathways in the nervous system that dampen pain signals. It may also inhibit inflammatory chemicals like prostaglandins and leukotrienes.

4. Heart Health and Diabetes Support

High blood pressure, high blood sugar and elevated “bad” cholesterol (low-density lipoprotein or LDL cholesterol) are all risk factors for heart disease. Ginger may help with all three.

A 2022 review of 26 clinical trials found that ginger supplementation can significantly improve cholesterol levels — lowering triglycerides, total cholesterol and LDL cholesterol, while raising HDL (“good”) cholesterol. It may also lower blood pressure.

For people with type 2 diabetes, ginger could offer additional benefits. A review of ten studies found that taking one to three grams of ginger daily for four to 12 weeks helped improve both cholesterol levels and blood sugar control.

These benefits appear to come from multiple mechanisms, including improved insulin sensitivity, enhanced glucose uptake in cells, and reduced oxidative stress. Ginger’s anti-inflammatory actions may also contribute to its heart-protective effects.

Some early research suggests that ginger may also offer benefits for sexual health, though evidence in humans is still limited. Animal studies have found that ginger can boost testosterone levels, improve blood flow, and enhance sexual behaviour. In traditional medicine systems, it has long been used as an aphrodisiac. While there’s not yet strong clinical evidence to confirm a direct impact on libido, ginger’s anti-inflammatory, circulatory and hormonal effects could play a supportive role, particularly for people managing conditions like diabetes or oxidative stress.

5. Brain Health

Emerging evidence suggests ginger may also offer neuroprotective and anti-cancer benefits. Lab-based studies show that ginger compounds can help protect brain cells from oxidative damage – a key factor in neurodegenerative diseases like Alzheimer’s.

Other in-vitro research has found that ginger can slow the growth of some cancer cells. However, these findings are still in early stages and more research is needed to confirm their relevance in humans.

Ginger is generally safe when consumed in food or tea. But like any supplement, it should be used in moderation.

Doses above four grams a day may cause side effects such as heartburn, bloating, diarrhoea or mouth irritation. These are usually mild and temporary.

Certain groups should use caution with high doses. Ginger may increase bleeding risk in people on blood thinners (like warfarin, aspirin or clopidogrel), and it can enhance the effects of diabetes or blood pressure medications, potentially leading to low blood sugar or blood pressure. Pregnant women should also consult a doctor before using high doses.

So ginger isn’t just a fragrant kitchen spice – it’s a natural remedy with growing scientific support. For most people, enjoying ginger in food or tea is a safe and effective way to tap into its therapeutic potential. If you’re considering taking supplements, it’s always best to speak with your doctor or pharmacist first, especially if you’re managing a medical condition or taking medication.

Sen. Wyden Wants to Censor Pain Experts’ Opinions

By Lynn Webster, MD, Guest Columnist

In 2016, the Comprehensive Addiction and Recovery Act (CARA) created an advisory panel called the Pain Management Best Practices Inter-Agency Task Force and charged it to “develop a set of best practices for chronic and acute pain management and prescribing pain medication.”

The task force has just released its first draft report that makes several recommendations. One is to update the scientific evidence on which the Centers for Disease Control and Prevention’s controversial 2016 Guideline for Prescribing Opioids for Chronic Pain was based. Another goal is to expand areas already included in the guideline.

On December 18, 2018, just before the report was published, Oregon Senator Ron Wyden (D) wrote a letter to Alex Azar, Secretary of Health and Human Services (HHS). In it, he questioned the ability of several experts to serve impartially on the task force because of their alleged connections to the pharmaceutical industry. Specifically, Sen. Wyden worried that opioid manufacturers could exert “financial influence” on those task force members.

Wyden’s concerns about the HHS’s vetting practices would be understandable if the individuals who had been appointed to the advisory panel actually were receiving funds directly from industry. However, that is not the case.

Wyden’s letter specifically mentions Dr. Jianguo Cheng, president of the American Academy of Pain Medicine (AAPM), and Dr. Rollin Gallagher, editor-in-chief of the journal Pain Medicine.

In his letter, Wyden opposes Drs. Cheng and Gallagher’s participation primarily because of their association with AAPM, a professional medical organization that has registered concerns about the impact of the CDC’s opioid prescribing guideline on people in chronic pain.

Dr. Josh Bloom, the American Council on Science and Health’s Director of Chemical and Pharmaceutical Sciences, recently shared written communications from Drs. Cheng and Gallagher that make it difficult to see any logical reason to object to their participation on the panel.

SEN. RON WYDEN (D-OR)

Since he became president-elect of the AAPM at the end of 2016, Dr. Cheng has had no financial ties to the pharmaceutical industry. Similarly, to ensure Pain Medicine’s editorial independence, Dr. Gallagher voluntarily ended his relationships — consulting or advisory— with the industry when he became editor-in-chief more than 10 years ago.

Ironically, the AAPM has long advocated for alternatives to opioids and generally supported the CDC guideline. However, they did have concerns about lack of evidence for some of the CDC’s recommendations. Other organizations, including the American Medical Association (AMA), have also criticized components of the CDC guideline.

Wyden has previously lodged a similar complaint with the National Academies of Sciences, Engineering, and Medicine, also challenging members selected for an FDA advisory panel because of a perceived conflict of interest. Following his complaint, Dr. Mary Lynn McPherson, professor at Maryland University School of Medicine, and Dr. Gregory Terman, who was the president of the American Pain Society, were removed from the panel. Here again, neither Dr. McPherson nor Dr. Terman personally received funds from Pharma. The University of Maryland and the American Pain Society, with which they were associated, did.

If Wyden’s reasoning were taken to its logical conclusion, no member of the AMA or any professional organization of pain experts critical of the CDC opioid guideline would be an acceptable member of the advisory panel. Also, most university faculty members would be disqualified because their universities accept funding, in one form or another, from industry.

Some people assume that any association with industry must create bias and cause conflicts of interest. Perhaps so, but that does not apply to the people Wyden is trying to silence. Further, membership in a professional association or serving as a faculty member of a university that receives industry support should not necessarily disqualify an individual to make an important contribution to committees. The goal should be to seek out the most qualified individuals.

There is danger associated with Wyden’s persistent efforts to purge advisory panels of members who have expressed views he doesn’t share. In essence, eliminating people with differing views from advisory panels stacks the deck. It creates a special-interest group that is empowered to influence policy without having to consider differing opinions. The irony is that this very attempt to limit bias creates bias.

Prohibiting experts with no direct connections to industries, like Drs. Cheng, Gallagher, McPherson and Teman, from participating on advisory panels seems to be a punitive gesture. Physicians and researchers, such as these four individuals, who actually care for patients are uniquely equipped to help advisory committees set best practices for pain management. And these panels cannot afford to lose the expertise that these individuals can provide.

If the vetting process includes removing all potential conflicts of interest, then it should also flag anyone who has ties to insurance, including Medicare. Clearly, insurance companies have a financial interest in which treatments are recommended.

Today, Wyden and others are calling to ban anyone with direct or indirect ties to Pharma from serving as a government adviser. Tomorrow, another industry could be targeted. For example, people who work in energy or university researchers who receive industry grants to study the weather might not be permitted to advise the government on climate change. This would likely mean the committees would be comprised of the least knowledgeable individuals.

Hopefully, the HHS and other governmental bodies will consider viewpoints from a broad swath of qualified experts and not just those whose perspectives they endorse. A functioning democracy must value and listen to all views.
