Historically, spices are treasured for the unique flavors they bring to food and for their healing properties.
Most spices provide some health benefits.
But one spice that shines for its medicinal benefits is turmeric.
You may have seen turmeric in the news as a potential treatment for diseases as diverse as arthritis, cancer, diabetes, heart disease, psoriasis, and Alzheimer’s.
But does this spice live up to its press?
And can you get the benefits of turmeric from food alone or should you take a turmeric supplement?
Turmeric and curcumin are often used interchangeably. What’s the difference between them?
Here’s everything you need to know about the health benefits of turmeric.
Traditional Health Benefits of Turmeric
Turmeric is a spice that comes from the root of Curcuma longa, a beautiful flowering tropical plant native to India.
Turmeric has been used for healing for thousands of years going back to Ayurveda, India’s 5,000-year-old natural healing system. (1)
Cooking residue found on pottery shards shows that people in parts of Asia cooked with turmeric 4,500 years ago. (2)
It is one of several spices used to make curry powder, an essential ingredient in south Asian cuisine.
It’s usually used dry, but the root can also be grated fresh like ginger.
It was applied externally for wounds and skin conditions.
It was also used as a beauty treatment. (5)
Soaps and creams containing turmeric are experiencing a surge in popularity today.
Turmeric paste is still applied to the skin of both the bride and groom in a ceremony before marriage in some parts of India, Bangladesh, and Pakistan to beautify skin and as a form of good luck.
The Relationship Between Turmeric and Curcumin
Many websites, even authoritative medical sites, incorrectly use the terms turmeric, curcumin, and even curry powder interchangeably.
This makes it hard to understand the information on turmeric.
Let’s clear up any confusion.
Curry powder is a mix of many spices including the spice turmeric.
Turmeric contains hundreds of compounds, each with its own unique properties.
But of all the compounds in turmeric, curcumin is by far the most promising and is the most widely studied.
Curcumin is not unique to turmeric, it is also found in ginger, another spice with a long history of medicinal use.
You can find many websites that make unrealistic claims about turmeric.
A few natural health websites boldly state that turmeric has been proven beneficial for over 600 ailments.
But the vast majority of studies were done on the isolated compound curcumin, not turmeric.
The National Center for Complementary and Integrative Health says this about turmeric studies: “… there is little reliable evidence to support the use of turmeric for any health condition because few clinical trials have been conducted.” (6)
Why would this be?
It’s easier to study a compound like curcumin which can be isolated and standardized and acts more drug-like than spice-like.
But the overriding reason may be that there is little monetary incentive to research a spice that’s already found in millions of kitchens worldwide unless it can be transformed into a substance that can be patented.
Proven Health Benefits of Turmeric
As we’ve seen, the majority of studies have been done on curcumin — not turmeric — and it looks like there aren’t many health conditions this compound won’t help.
Proven health benefits of curcumin include alleviating allergies, breaking up the brain plaques of Alzheimer’s, easing the pain of arthritis, treating depression, controlling diabetes, and decreasing risk of heart attack. (7, 8, 9, 10, 11, 12, 13)
But what about turmeric — what is it good for?
So far, turmeric has been found to contain at least 20 compounds that are antibiotic, 14 known cancer preventatives, 12 that are anti-tumor, 12 anti-inflammatory, and at least 10 antioxidants. (14)
And studies point to a few specific conditions that turmeric can help.
Turmeric for Alzheimer’s
One of the most exciting benefits of turmeric is that it may prevent Alzheimer’s.
Elderly villagers in India who eat turmeric as a regular part of their diet have the lowest rate of Alzheimer’s in the world. (17)
Over 200 compounds have been identified in turmeric and curcumin is not the only one being studied for Alzheimer’s. (18)
Another compound in turmeric, turmerone, stimulates the production of new neurons and seems to encourage the brain to repair itself. (19)
This property could make it a useful treatment for a variety of degenerative brain diseases besides Alzheimer’s, including Parkinson’s, traumatic brain injury, and stroke. (20)
Turmeric for Arthritis
Arthritis and other inflammatory diseases are extremely common.
Over $650 million is spent in the United States every year on natural remedies for treating chronic inflammation.
Turmeric is anti-inflammatory and has been found to be beneficial for arthritis when taken internally and when applied topically. (21)
The Arthritis Foundation reports that turmeric can provide long-term improvement in pain and function for those with osteoarthritis.
Their suggested dosage for osteoarthritis is to take one capsule (400-600 mg) three times per day or 0.5-1.0 gram of powdered turmeric root up to 3 grams per day.
Turmeric for Cancer
Curcumin is a promising candidate as a cancer treatment. (22)
It selectively kill tumor cells while leaving normal cells unharmed and works synergistically to increase the effectiveness of both chemotherapy and radiation. (23)
Dr. Saraswati Sukumar is a medical oncologist at the Johns Hopkins University School of Medicine and has been involved in hundreds of studies on the effects of turmeric on cancer. (24)
She has found that eating turmeric prepared in food provides more benefits than taking either curcumin or turmeric supplements. (25)
Turmeric Is Better than Prozac for Depression
Turmeric has impressive antidepressant properties.
In fact it’s been found to be more a more potent antidepressant than fluoxetine, the generic name for Prozac. (26)
It is believed to work by reducing the stress hormone cortisol while increasing serotonin, the neurotransmitter associated with happiness.
This is great news for the millions who have tried antidepressants without success or for those who experience unacceptable side effects (27)
Unlike antidepressant drugs, turmeric either in food or as a supplement can used indefinitely.
Enhancing Turmeric Naturally
Unfortunately, turmeric’s main active ingredient curcumin is not very well absorbed.
Unless the right steps are taken, it largely passes through the intestines unutilized.
You can greatly increase absorption by adding black pepper, as is done in curry powder.
The compound piperine found in black pepper increases curcumin absorption by a whopping 2,000%. (29)
Since curcumin is fat soluble, its bioavailability is enhanced when turmeric is cooked in oil. (30)
Again, tradition has this covered.
Indian cuisine liberally uses peanut, sesame and coconut oil, and butter-derived ghee. (31)
Turmeric tea is a great compromise between to trying to get enough turmeric into your daily diet and taking supplements.
Boiling turmeric in water for 10 minutes increases the solubility of curcumin up to 12 times. (32)
The people of Okinawa, Japan are the longest-lived in the world, with an average life span of 81.2 years.
And they drink large amounts of turmeric tea. (33)
To make basic turmeric tea, put 1/2 teaspoon of turmeric powder in 1 cup of water and simmer for 10 minutes.
Strain if needed and serve.
If you actually enjoy it, you’re in luck because not everyone is crazy about it.
It’s very bitter and medicinal-tasting.
I’ve been experimenting to find a recipe that’s both healthy and delicious.
This recipe is tasty and assures maximum bioavailability by both heating and adding coconut oil, a top brain-healthy fat.
Liquid Gold Turmeric Tea
1/2 cup water
1/2 teaspoon turmeric powder
1/2 cup coconut milk
1 tablespoon coconut oil
Honey or stevia to taste
Bring water to a boil. Add turmeric powder and simmer gently for 10 minutes.
Add coconut milk and coconut oil. Heat until warmed through.
Sweeten with honey or stevia to taste.
Feel free to experiment with the ingredients and proportions to create the brew that is just right for you.
You can substitute almond milk or regular milk for coconut milk, as long as it contains some fat.
Ghee, traditional clarified Indian butter, works great instead of coconut oil and adds a rich buttery flavor.
Most of us in Western countries are familiar only with the turmeric found in the dried spice section at the grocery store.
But you can buy turmeric root in some produce sections — it looks a lot like ginger, a plant cousin that’s another source of curcumin.
According to the University of Maryland’s Complementary and Alternative Medicine Guide, here are suggested turmeric dosages for adults:
Cut root: 1.5-3 grams per day
Dried, powdered root: 1-3 grams per day
Fluid extract (1:1): 30-90 drops per day
Tincture (1:2): 15-30 drops, 4 times per day
Their recommended curcumin dosage for a standardized powder supplement is 400-600 mg, 3 times per day.
Look for products standardized for 95% curcuminoids that also contain piperine or black pepper extract.
When unsure, follow the dosage instructions on labels. (34)
Turmeric Supplement Side Effects
Turmeric consumed as a spice in food is considered safe.
There are almost no known turmeric side effects except for an increased risk of kidney stones in those susceptible. (35)
But I was somewhat surprised to learn that turmeric supplements carry a large number of possible side effects, interactions, and warnings.
While clearly turmeric and curcumin are not identical, their respective side effects and reactions are treated as one on sites like Drugs.com, RXlist.com, and the National Institutes of Health’s MedLine.
All three sites were in agreement that you should not take either curcumin or turmeric supplements if:
You are pregnant. Curcumin stimulates the uterus and raises the risk of a miscarriage. The safety of this spice while breastfeeding has not been established.
You are trying to conceive. If you are having trouble conceiving, turmeric could add to your difficulties.
You have a hormone-sensitive condition. Turmeric can act like estrogen so should be avoided if you have reproductive cancer, endometriosis, or uterine fibroids.
You have gallstones or gallbladder disease. Turmeric can make gallbladder problems worse.
You are scheduled for surgery in the next two weeks. Turmeric increases the risk of bleeding.
You take medications that slow clotting such as aspirin, clopidogrel, diclofenac, ibuprofen, naproxen, and warfarin. Turmeric increases the risk of bruising and bleeding.
You have GERD, ulcers, or other stomach problems. Turmeric can make GERD worse and cause gastric irritation, stomach upset, nausea, and diarrhea.
You take drugs to reduce stomach acid. Turmeric can interfere with the actions of medications like Zantac, Tagamet, and Nexium, increasing the production of stomach acid. (36)
You take diabetes medication. Turmeric increases the risk of hypoglycemia (low blood sugar).
You have an iron deficiency. Turmeric can prevent the absorption of iron.
According to Drugs.com, 70 drugs interact adversely with turmeric and curcumin supplements.
You can find a complete list of turmeric interactions here.
Turmeric Benefits: The Bottom Line
Turmeric is a traditional healing spice with a long history of safe and effective use.
While there are turmeric capsules and turmeric tinctures available, their bioavailability is questionable.
They are also significantly more likely to cause side effects than cooking with turmeric which has no downside.
Some experts believe that the liberal use of turmeric in cooking is all you need to get therapeutic amounts.
We agree that it’s prudent to start first with turmeric in food and tea for that sweet spot of maximum benefits with virtually no risk of side effects.
And if you don’t get the results you want, you can try turmeric supplements.
If that still doesn’t bring the relief you’re looking for, then you can try curcumin supplements, staying mindful of interactions and side effects.
