Like many spices, organic turmeric (Curcuma longa) has a long history of use in traditional medicine. This flavor-filled spice is primarily cultivated from the rhizomes, or roots, of a flowering plant that grows in India and other parts of Southeast Asia, and aside from giving curry its vibrant yellow color, organic turmeric ground is also known for having potent anti-inflammatory and antioxidant properties, according to a past review.
The primary active component of turmeric — and the one that gives the spice its characteristic yellow color — is curcumin.
Indeed, you can credit curcumin with most of turmeric’s potential health benefits.

1. Curcumin Is an Anti-Inflammatory
One of turmeric’s main claims to fame is that it’s commonly used to fight inflammation, and the bulk of turmeric’s inflammation-fighting powers can be assigned to curcumin. In fact, in the right dose, curcumin may be a more effective anti-inflammatory treatment than common inflammation-fighting medications such as ibuprofen and aspirin, according to a past study.
More research is needed in this area as well. Because chronic inflammation contributes to many chronic diseases, curcumin may help treat conditions like inflammatory bowel disease, pancreatitis, and arthritis, according to a past review.
2. Curcumin May Help Protect Against Heart Disease
A past study shows that curcumin may improve endothelial function, or the health of the thin membrane that covers the inside of the heart and blood vessels. This membrane plays a key role in regulating blood pressure.
Lower endothelial function is associated with aging and an increased risk of heart disease. Thus, curcumin may help protect against age-related loss of function and reduce your likelihood of developing heart disease. In one study, researchers compared the effects of an eight-week aerobic exercise program and a curcumin supplement in improving endothelial function in post-menopausal women. Both the exercise and the curcumin group saw equal improvements in endothelial function, whereas the control group saw no changes.
Organic cinnamon Ceylon also reduces risk of heart disease.
3. Curcumin May Help Prevent (and Possibly Treat) Certain Types of Cancer
As inflammation is linked to tumor growth, anti-inflammatory compounds such as curcumin may play a role in the treatment and prevention of a variety of cancer types, including colorectal, pancreatic, prostate, breast, and gastric cancers.
Research in mice suggests that curcumin may help slow the spread of tumor cells and may even prevent tumors from forming in the first place.
It may do this in several ways, including disrupting the formation of cancerous cells at various stages in the cell cycle, interfering with cell signaling pathways, and even causing those cancerous cells to die.
Whether curcumin can help treat cancer in humans has yet to be determined, but the research is ongoing. Some research also suggests that turmeric or curcumin can help with certain cancer symptoms. One review of 11 studies on the effects of turmeric on prostate diseases (including eight studies on patients with prostate cancer), published online in August 2021 as part of the Advances in Experimental Medicine and Biology book series, suggests that supplementing with turmeric or curcumin may offer perks.
While some studies found curcumin or turmeric supplements had no effect on patients with prostate diseases, a few showed beneficial effects on levels of prostate-specific antigen (a protein produced by the prostate gland; blood levels of this protein are typically higher in men with prostate cancer), urination frequency and urgency, and quality of life.
4. Curcumin May Help Ease Symptoms of Osteoarthritis
Thanks to its potent anti-inflammatory properties, curcumin may be a safe and effective long-term treatment option for people with osteoarthritis (OA). At least, that was the conclusion of the authors of a recent review of the clinical use of curcumin for the treatment of osteoarthritis. The review was first published online in August 2021 as part of the Advances in Experimental Medicine and Biology book series.
In a past study, people with osteoarthritis who took 1,000 mg per day of Meriva experienced significant improvements in stiffness and physical function after eight months, whereas the control group saw no improvements. Meriva is a proprietary treatment made up of a natural curcuminoid mixture (75 percent curcumin; 15 percent demethoxycurcumin; and 10 percent bisdemethoxycurcumin), phosphatidylcholine (a chemical found in eggs, soybeans, and other foods),
and microcrystalline cellulose (a refined wood pulp commonly used by the pharmaceutical and food industries).
Meanwhile, a recent clinical trial studied the potential effects of curcumin supplements on patients with knee ostearthritis. The group that took 40 mg of nanocurcumin in a capsule every 12 hours experienced a significant decrease in pain and stiffness after six weeks compared with the control group. The findings were published in 2020 in Current Rheumatology Reviews.
And a study in mice published in the June 2016 issue of Arthritis Research & Therapy found that 50 mg oral curcumin per kg of body weight significantly slowed the progression of OA, whereas a topical curcumin treatment provided pain relief.
5. Curcumin May Help Treat or Prevent Diabetes
According to a past review of studies, curcumin may help treat and prevent diabetes, as well as associated disorders like diabetic nephropathy (also called diabetic kidney disease), which affects people with type 1 diabetes and type 2 diabetes.
One drawback: Many of the studies were done only in animals, not humans. For example, one study found that feeding 80 mg of tetrahydrocurcumin (one of the main substances in curcumin) per kg of body weight to rats with type 2 diabetes for 45 days led to a significant decrease in blood sugar, as well as an increase in plasma insulin.
A study of obese mice with type 2 diabetes published in the July 2019 issue of Nutrition & Metabolism revealed that curcumin supplements helped lower blood insulin levels after 16 weeks.
The authors of a recent review note that curcumin may be a good adjunct to diabetes treatment to improve insulin resistance and blood sugar control, and lower blood lipids (fatty substances found in the blood). The findings were published in August 2021 in Evidence-Based Complementary and Alternative Medicine.
Meanwhile, curcumin may help prevent diabetes through its anti-inflammatory and antioxidant properties, and improve many of the factors that contribute to diabetes, including insulin resistance, high blood sugar, and hyperlipidemia (a medical term to describe elevated levels of fat in the blood; one type of hyperlipidemia is characterized by high levels of LDL or "bad" cholesterol).
Cinnamon Ceylon also help prevent diabetes .
6. Curcumin May Help Delay or Reverse Alzheimer’s Disease
Organic turmeric may even help protect your brain against common degenerative diseases like Alzheimer’s. How? By increasing levels of brain-derived neurotrophic factor (BDNF), a protein found in the brain and spinal cord that plays a key role in keeping nerve cells (neurons) healthy, as well as regulating communication between nerve cells, which is critical for learning and memory.
As common brain disorders like Alzheimer’s are associated with lower levels of BDNF, turmeric (curcumin in particular) may help delay or reverse brain degeneration.
That said, much of the research has been done in rats.
Researchers note more research is needed to confirm the effectiveness of turmeric in the prevention and treatment of common brain diseases.
7. Curcumin May Play a Role in Depression Treatment
Like Alzheimer’s, depression is associated with lower levels of BDNF. Thanks to turmeric’s ability to boost levels of BDNF, the spice shows promise as an effective antidepressant. In fact, one study found that rats injected with 50, 100, or 200 mg/kg of curcumin for 10 days had a dose-dependent increase in BDNF, with the higher dose of 200 mg/kg showing greater antidepressant effects.
Meanwhile, in a study in humans that was published in Phytotherapy Research, researchers randomly assigned 60 patients with major depressive disorder to one of three groups: One group received daily 20 mg of fluoxetine ,another received 1,000 mg of curcumin, and a third received a combination of the two. By the end of six weeks, the three groups saw comparable improvements, leading researchers to suggest that curcumin may be a safe and effective treatment for major depressive disorder.
Still, scientists don’t fully understand the role of turmeric and curcumin in treating depression, and more research in humans is needed to confirm it is a safe and effective treatment. You should consult your primary care practitioner before beginning or changing any medications you may be taking.
8. Curcumin May Play a Role in Treating Rheumatoid Arthritis
Curcumin shows promise as a treatment for rheumatoid arthritis (RA), a chronic inflammatory disorder that commonly affects the joints but may spread to other areas, such as the eyes, lungs, skin, heart, and blood vessels.
RA causes a painful swelling of the joints that can cause the bones to erode over time and ultimately lead to deformities and physical disabilities.
In one study, people with RA were given 500 mg of curcumin, 50 mg of diclofenac sodium (a prescription nonsteroidal anti-inflammatory drug), or the two in combination.
After eight weeks, the curcumin-only group saw significant improvements in joint tenderness and swelling when compared with the other two groups. Researchers note the curcumin treatment was also safe, resulting in no harmful events
9. Turmeric May Improve Skin Health
Thanks to its anti-inflammatory, antimicrobial, and antioxidant properties, organic turmeric ground may be an effective treatment for a variety of skin conditions, including acne, eczema (atopic dermatitis), photoaging, and psoriasis. Yet robust research is lacking.
A review published in the January 2018 issue of Open Access Macedonian Journal of Medical Sciences suggests oral curcumin in particular may be an effective and safe treatment option for psoriasis (a chronic inflammatory skin disease), but more studies are needed before doctors make recommendations.
According to the authors of another review, topical curcumin treatments may be useful in treating skin disorders, especially as past research suggests curcumin is relatively safe even at high doses. But curcumin’s bright yellow-orange color, poor solubility, and poor stability at a high pH make it an unappealing topical skin treatment.

10. Turmeric Protects Your Body From Free Radicals
Antioxidants help protect your body against damage caused by free radicals, a class of highly reactive atoms that are generated in our bodies and found in environmental pollutants like cigarette smoke and industrial chemicals.
Too much exposure to free radicals can mess with the fats, proteins, and even DNA in your body, which may lead to a number of common diseases and health conditions, including cancer, arthritis, heart disease, and Alzheimer’s.
Therefore, antioxidant-rich spices like organic turmeric may play a role in protecting you from free radical damage. Curcumin in particular is able to scavenge different types of free radicals, control enzymes that neutralize free radicals, and prevent certain enzymes from creating specific free radical types, according to a review in the October 2017 issue of Foods.
